But, due to paucity of instrumental records, such effects are poorly studied, particularly in mountains outside Europe and North America. Here, we quantified water body area fluctuations for the last 32 years in 15 lakes spread over an area of 14.3 million ha in the Argentine Puna, through the classification of Landsat images; and we quantified peatlands NDVI (a proxy of vegetation productivity) from MODIS images. We evaluated the pairwise similarity between lakes interannual fluctuations and their relationship with climate models (TRMM 3B43 v7; CRU TS 4.10) and potential controls (ENSO index); and the correlations between water body area and the NDVI variation of its associated peatlands. Lakes were grouped in two clusters defined by their synchronic water body area variability and these clusters define two main geographic zones: NE and SW. Consistent with previous observations of an overall aridization trend, water body area generally decreased but showed large variability among lakes. Peatlands productivity was more correlated with lake variability than with modeled precipitation, and lake water body area was weakly related to indices of ENSO, providing an additional tool to relate local climate with continental and global climate models. The analysis shows that lake behavior is highly variable spatially and temporally, and that satellite-based monitoring is a valuable tool for assessing ecological conditions of wetlands in the region, characterized by the lack of climatic instrumental records; and to explore the vulnerability of wetlands to climate change.","publicationDate":"2019-01-01","doi":"10.1007/s10113-019-01514-7","url":"https://andes.mountain-wetlands-repository.info/api/v1/items/56aa8093-1e9b-4b97-b256-03c916387f66","timeperiod_startdate":null,"timeperiod_enddate":null,"placename":null,"country_code":null,"source_details":{"id":7,"name":"Mountain Wetlands Repository","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":"Mountain Wetlands Repository (MaRESS)","works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Casagranda","et al."],"keywords":["Peat","Wetland","Cru","Environmental science","Physical geography","Climate change","Normalized Difference Vegetation Index","Precipitation","Lake ecosystem","Vegetation (pathology)","Climatology","Ecosystem","Hydrology (agriculture)","Geography","Ecology","Geology"],"topics":["Peatlands and Wetlands Ecology","Climate variability and models","Hydrology and Watershed Management Studies"],"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":"https://openalex.org/W2947164770","openalex_match_info":null,"openalex_fulltext_origin":"journal","openalex_is_retracted":false,"openalex_ids":{"doi":"https://doi.org/10.1007/s10113-019-01514-7","mag":"2947164770","openalex":"https://openalex.org/W2947164770"},"openalex_open_access_status":"bronze"}},{"id":747,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[{"type":"Point","coordinates":[-68.30397835688937,-23.539188356282335]}]},"bbox":[-68.30397835688937,-23.539188356282335,-68.30397835688937,-23.539188356282335],"properties":{"title":"Solute inputs in the Salar de Atacama (N.

Glacial lake outburst floods (GLOFs) pose risks to exposed and vulnerable populations and can be linked in part to long-term post-Little Ice Age climate change because precariously dammed glacial lakes sometimes formed as glaciers generally retreated after the mid-1800s. This paper provides an interdisciplinary and historical analysis of 40 years of glacier hazard management on Mount Hualcán, at glacial Lake 513, and in the city of Carhuaz in Peru’s Cordillera Blanca mountain range. The case study examines attempted hazard zoning, glacial lake evolution and monitoring, and emergency engineering projects to drain Lake 513. It also analyzes the 11 April 2010 Hualcán rock-ice avalanche that triggered a Lake 513 GLOF; we offer both a scientific assessment of the possible role of temperature on slope stability and a GIS spatial analysis of human impacts. Qualitative historical analysis of glacier hazard management since 1970 allows us to identify and explain why certain actions and policies to reduce risk were implemented or omitted. We extrapolate these case-specific variables to generate a broader socio-environmental framework identifying factors that can facilitate or impede disaster risk reduction and climate change adaptation. Facilitating factors are technical capacity, disaster events with visible hazards, institutional support, committed individuals, and international involvement. Impediments include divergent risk perceptions, imposed government policies, institutional instability, knowledge disparities, and invisible hazards. This framework emerges from an empirical analysis of a coupled social-ecological system and offers a holistic approach for integrating disaster risk reduction and climate change adaptation.","publicationDate":"2012-01-01","doi":"10.1007/978-3-642-31110-9_34","url":"https://andes.mountain-wetlands-repository.info/api/v1/items/ae4ea8c4-1fd0-444b-8218-050d4d94028f","timeperiod_startdate":null,"timeperiod_enddate":null,"placename":null,"country_code":null,"source_details":{"id":7,"name":"Mountain Wetlands Repository","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":"Mountain Wetlands Repository (MaRESS)","works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Carey","et al."],"keywords":["Adaptation (eye)","Vulnerability (computing)","Livelihood","Supply chain","Climate change","Scale (ratio)","Adaptive capacity","Business","Disaster risk reduction","Environmental resource management","Environmental economics","Agriculture","Risk analysis (engineering)","Computer science","Geography","Economics","Marketing","Ecology"],"topics":["Climate change impacts on agriculture","Agricultural Innovations and Practices","Agricultural risk and resilience"],"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":"https://openalex.org/W23057450","openalex_match_info":null,"openalex_fulltext_origin":"book series","openalex_is_retracted":false,"openalex_ids":{"doi":"https://doi.org/10.1007/978-3-642-31110-9_34","mag":"23057450","openalex":"https://openalex.org/W23057450"},"openalex_open_access_status":null}},{"id":745,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[{"type":"Point","coordinates":[-77.673074179185,-8.994891179906146]},{"type":"Point","coordinates":[-77.62877095246509,-9.061735050494194]},{"type":"Point","coordinates":[-77.64533187163184,-9.074655406775266]}]},"bbox":[-77.673074179185,-9.074655406775266,-77.62877095246509,-8.994891179906146],"properties":{"title":"Living and dying with glaciers: people's historical vulnerability to avalanches and outburst floods in Peru","type":"article","abstract":"Human populations worldwide are vulnerable to natural disasters.

Guanacos spent more time in the shrubsteppe than in the vegas, where the highest percentage of vigilant guanacos was recorded. A positive and significant relationship between time devoted to foraging and number of animals per herd was observed in both habitats.

High solar irradiance occurs in an atmosphere permanently depleted in ozone falling below ozone hole definition for 33–36 days and between 30 and 35% depletion the rest of the year.

Ultimately, the purpose of this approach is to achieve an inclusive and viable plan for conservation and management of existing resources. The participatory analysis provided local people’s perceptions of bofedal (wetland) and tolar (shrubland) ecosystem services, as well as their assessment of likely scenarios for the future. We identified 2 important factors in the hypotheses the local people provided: extreme events such as water scarcity and drought, and participation of the private sector in water distribution. Participants estimated that water storage and fuel for cooking were likely to have the strongest effects on current and future ecosystem services. Based on this, we jointly developed hypotheses using a stepwise approach and used software to calculate probabilities in a systematic way and produce a series of scenarios. The likelihood of these scenarios was also assessed by groups of stakeholders, yielding 5 scenarios for consideration in designing management plans. Future scenarios are highly dependent on proper management of the bofedal. We conclude that foresight helps to involve local people better in the process of developing viable strategies for the future of the reserve and for the conservation of the natural resources that it harbors.","publicationDate":"2018-01-01","doi":"10.1659/mrd-journal-d-17-00090.1","url":"https://andes.mountain-wetlands-repository.info/api/v1/items/eb3bca99-4b4b-4357-8d7a-421638258ba1","timeperiod_startdate":null,"timeperiod_enddate":null,"placename":null,"country_code":null,"source_details":{"id":7,"name":"Mountain Wetlands Repository","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":"Mountain Wetlands Repository (MaRESS)","works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Blancas","et al."],"keywords":["Ecosystem services","Futures studies","Environmental resource management","Business","Ecosystem","Scenario analysis","Environmental planning","Environmental economics","Environmental science","Ecology","Computer science","Economics"],"topics":["Land Use and Ecosystem Services","Conservation, Biodiversity, and Resource Management","Economic and Environmental Valuation"],"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":"https://openalex.org/W2896018625","openalex_match_info":null,"openalex_fulltext_origin":"journal","openalex_is_retracted":false,"openalex_ids":{"doi":"https://doi.org/10.1659/mrd-journal-d-17-00090.1","mag":"2896018625","openalex":"https://openalex.org/W2896018625"},"openalex_open_access_status":"gold"}},{"id":737,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[{"type":"Point","coordinates":[-72.28933653568669,6.497502517174405]},{"type":"Point","coordinates":[-72.27844191689233,6.476974101837528]},{"type":"Point","coordinates":[-75.34265794082854,4.859408811500626]}]},"bbox":[-75.34265794082854,4.859408811500626,-72.27844191689233,6.497502517174405],"properties":{"title":"The influence of climate change on recent peat accumulation patterns of Distichia muscoides cushion bogs in the high-elevation tropical Andes of Colombia","type":"article","abstract":"extensive cushions of Distichia muscoides found at high elevations in the Andes form deep deposits of peat and function as peatland. The location of Distichia peatlands at the highest elevations makes them susceptible to the effects of global change including global warming.

This study used 210Pb chronologies to infer the recent dynamics of three Distichia muscoides peatlands located above 4000 m in elevation. Chronological markers from dated volcanic eruptions were correlated to the 210Pb chronologies of Distichia peat and validated the 210Pb chronologies. Changes in 210Pb activity with depth indicated rapid accumulation in recent times. Organic matter had a mean accumulation rate of 1400 g m_x0001_2 yr_x0001_1 during the past 10 years, with values well above the observed regional accumulation rate of 300–400 g m_x0001_2 yr_x0001_1. The same pattern was observed in peat accretion rates, with growth rates of 1–2 cm per year during the last 10 years. Cushion plants engineer their own environment, allowing the system to be less susceptible to direct changes in climate. However, the high rates of peat accretion in recent times may be originated from increasing temperatures and excess water from nearby glacier melt. However, glaciers are predicted to disappear during the next 20 years in the northern Andes, reducing water inputs in tropical high-elevation ecosystems.","publicationDate":"2013-01-01","doi":"10.1002/2013jg002419","url":"https://andes.mountain-wetlands-repository.info/api/v1/items/1a528093-02cd-4b7c-a2e8-f80168a31f55","timeperiod_startdate":null,"timeperiod_enddate":null,"placename":null,"country_code":null,"source_details":{"id":7,"name":"Mountain Wetlands Repository","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":"Mountain Wetlands Repository (MaRESS)","works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Benavides","et al."],"keywords":["Peat","Glacier","Climate change","Physical geography","Geology","Ecosystem","Bog","Global warming","Water table","Elevation (ballistics)","Accretion (finance)","Environmental science","Organic matter","Hydrology (agriculture)","Ecology","Geomorphology","Oceanography","Geography","Groundwater"],"topics":["Peatlands and Wetlands Ecology","Geology and Paleoclimatology Research","Coastal wetland ecosystem dynamics"],"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":"https://openalex.org/W1558632136","openalex_match_info":null,"openalex_fulltext_origin":"journal","openalex_is_retracted":false,"openalex_ids":{"doi":"https://doi.org/10.1002/2013jg002419","mag":"1558632136","openalex":"https://openalex.org/W1558632136"},"openalex_open_access_status":"bronze"}},{"id":736,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[{"type":"Point","coordinates":[-75.0,0.0]},{"type":"Point","coordinates":[-72.661910048034,7.358248889913305]},{"type":"Point","coordinates":[-72.68569691130482,6.611848085623589]},{"type":"Point","coordinates":[-72.29792881479,6.452236825569937]},{"type":"Point","coordinates":[-73.43069020889213,5.65052100787539]},{"type":"Point","coordinates":[-73.27755347966955,5.150574627178138]},{"type":"Point","coordinates":[-73.59621299709595,5.379153715650078]},{"type":"Point","coordinates":[-74.01846500781996,5.180413769269302]},{"type":"Point","coordinates":[-73.76511380138551,4.485668460958033]},{"type":"Point","coordinates":[-74.19074382819532,4.260467388571881]},{"type":"Point","coordinates":[-74.28645428395944,4.24470331350485]},{"type":"Point","coordinates":[-74.2188939622436,4.093818595006131]},{"type":"Point","coordinates":[-75.33589128127889,4.933818595006463]},{"type":"Point","coordinates":[-75.34827734026014,4.803201973022497]},{"type":"Point","coordinates":[-75.30661514186869,4.646687227714123]},{"type":"Point","coordinates":[-75.50929610701623,6.709529050771242]},{"type":"Point","coordinates":[-75.6770709059439,6.604810552111683]},{"type":"Point","coordinates":[-75.64216473972405,6.455051838974894]},{"type":"Point","coordinates":[-75.26270093275336,5.150011624497167]},{"type":"Point","coordinates":[-76.50581085232487,4.028510284014144]}]},"bbox":[-76.50581085232487,0.0,-72.29792881479,7.3582488899133045],"properties":{"title":"Response curves and the environmental limits for peat-forming species in the northern Andes","type":"article","abstract":"Peatlands, with organic soils, are usually dominated by one or a few species.

Understanding how these species relate to climatic or water chemistry gradients will help to predict the fate of those ecosystems under current climate change. The patterns of abundance and occurrence of 12 major peat-forming species from different structural plant groups were quantified along gradients of elevation, precipitation, and water chemistry. The species were distributed in four major structural groups: cushion plants, true mosses, sedges, and Sphagnum mosses. A response curve for each species was built with Generalized Additive Models. Niche breadths, species tolerances, and species optima were estimated using bootstrap resampling. Our results showed that species were limited in their elevational ranges; Sphagnum species were biased toward low to intermediate elevations, sedges, and true mosses to intermediate elevations and cushion plants to very high elevations. Sphagnum species were more likely to occur in sites with low precipitation, while sedges preferred wet sites. Sphagnum species preferred habitats with acidic pH. The species tolerances and optimum distributions are an indication to the vulnerability of the species to changes in their environment. Species with limited tolerances are more vulnerable, such as the narrow elevational distribution of cushion plants or the low pH and narrow tolerances observed for Sphagnum species. Climate and hydrological changes will very possibly affect the distribution of those species forcing changes on ecosystem functioning.","publicationDate":"2014-01-01","doi":"10.1007/s11258-014-0346-7","url":"https://andes.mountain-wetlands-repository.info/api/v1/items/3802f2db-3066-4ce3-9067-9df43d88675c","timeperiod_startdate":null,"timeperiod_enddate":null,"placename":null,"country_code":null,"source_details":{"id":7,"name":"Mountain Wetlands Repository","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":"Mountain Wetlands Repository (MaRESS)","works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Benavides","Vitt"],"keywords":["Sphagnum","Peat","Ecology","Ombrotrophic","Species distribution","Abundance (ecology)","Ecosystem","Indicator species","Environmental science","Bog","Biology","Habitat"],"topics":["Peatlands and Wetlands Ecology","Coastal wetland ecosystem dynamics","Botany and Plant Ecology Studies"],"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":"https://openalex.org/W2048154645","openalex_match_info":null,"openalex_fulltext_origin":"journal","openalex_is_retracted":false,"openalex_ids":{"doi":"https://doi.org/10.1007/s11258-014-0346-7","mag":"2048154645","openalex":"https://openalex.org/W2048154645"},"openalex_open_access_status":null}},{"id":735,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[{"type":"Point","coordinates":[-73.431,5.69318]},{"type":"Point","coordinates":[-73.43,5.69245]},{"type":"Point","coordinates":[-73.431,5.69396]},{"type":"Point","coordinates":[-73.432,5.69373]},{"type":"Point","coordinates":[-73.431,5.69476]},{"type":"Point","coordinates":[-73.429,5.69317]},{"type":"Point","coordinates":[-73.424,5.69772]},{"type":"Point","coordinates":[-73.432,5.69528]},{"type":"Point","coordinates":[-73.424,5.69939]},{"type":"Point","coordinates":[-73.423,5.69838]},{"type":"Point","coordinates":[-73.426,5.70092]},{"type":"Point","coordinates":[-73.425,5.70004]},{"type":"Point","coordinates":[-73.426,5.70307]},{"type":"Point","coordinates":[-73.426,5.70215]},{"type":"Point","coordinates":[-73.44,5.68906]},{"type":"Point","coordinates":[-73.439,5.68963]},{"type":"Point","coordinates":[-73.439,5.69247]},{"type":"Point","coordinates":[-73.439,5.69092]},{"type":"Point","coordinates":[-73.439,5.69342]},{"type":"Point","coordinates":[-73.44,5.69087]},{"type":"Point","coordinates":[-73.426,5.69817]},{"type":"Point","coordinates":[-73.425,5.69898]},{"type":"Point","coordinates":[-73.426,5.70481]},{"type":"Point","coordinates":[-73.426,5.69801]},{"type":"Point","coordinates":[-73.428,5.70706]},{"type":"Point","coordinates":[-73.428,5.71151]}]},"bbox":[-73.44,5.6890599999999925,-73.423,5.711510000000001],"properties":{"title":"The effect of drainage on organic matter accumulation and plant communities of high-altitude peatlands in the Colombian tropical Andes","type":"article","abstract":"The tropical Andes store and regulate water outflow that serves nearly 60 million people.

The ability of peat to store water and carbon was also reduced in drained peatlands. Vegetation records show a shift towards sedge-Juncus communities around 50 years ago when agricultural use of water increased.

We assessed the response of vegetation to the exclusion of grazing by pack animals over one growing season in the highest park in the Southern Hemisphere, Aconcagua Provincial Park, dry Central Andes. Twenty pairs of exclosures and unfenced quadrats were established in three high-altitude Andean alpine meadows that are intensively grazed by horses and mules used by commercial operators to transport equipment for tourists.

Data was analyzed using mixed models and ordinations. Vegetation responded rapidly to the removal of grazing. Vegetation in exclosures was more than twice as tall, had 30% more above-ground biomass, a greater cover of grasses including the dominant Deyeuxia eminens, and less litter than grazed quadrats. These changes in the vegetation from short-term exclusion of grazing are likely to increase the habitat quality of the meadows for native wildlife.","publicationDate":"2014-01-01","doi":"10.1657/1938-4246-46.2.333","url":"https://andes.mountain-wetlands-repository.info/api/v1/items/8fb5e365-e877-49b9-aa53-f2f6643a6039","timeperiod_startdate":null,"timeperiod_enddate":null,"placename":null,"country_code":null,"source_details":{"id":7,"name":"Mountain Wetlands Repository","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":"Mountain Wetlands Repository (MaRESS)","works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Barros","et al."],"keywords":["Grazing","Vegetation (pathology)","Quadrat","Exclosure","Biomass (ecology)","Grazing pressure","Ecology","Geography","Environmental science","Livestock","Grassland","Forestry","Biology","Shrub"],"topics":["Wildlife Ecology and Conservation","Ecology and Vegetation Dynamics Studies","Rangeland and Wildlife Management"],"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":"https://openalex.org/W2059698574","openalex_match_info":null,"openalex_fulltext_origin":"journal","openalex_is_retracted":false,"openalex_ids":{"doi":"https://doi.org/10.1657/1938-4246-46.2.333","mag":"2059698574","openalex":"https://openalex.org/W2059698574"},"openalex_open_access_status":"bronze"}},{"id":733,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[{"type":"Point","coordinates":[-69.22392099735556,-18.188672848013784]}]},"bbox":[-69.22392099735556,-18.188672848013784,-69.22392099735556,-18.188672848013784],"properties":{"title":"Evolution of High Andean Puna Ecosystems: Environment, Climate, and Culture Change over the Last 12,000 Years in the Central Andes","type":"article","abstract":"In the High Andes, much of the traditional knowledge related to natural resource utilization and agricultural practices was lost with the arrival of the Spaniards.

As wetlands are vulnerable and particularly susceptible to changes of water supply, alterations and modifications in the hydrological regime have direct effects on their ecophysiological condition and vegetation cover. The aim of this study was to evaluate the potential of Worldview-2 and Sentinel-2 sensors to identify and map Andean wetlands through the use of the one-class classifier Bias support vector machines (BSVM), and then to estimate soil moisture content of the identified wetlands during snow-free summer using partial least square regression.\nThe results obtained in this research showed that the combination of remote sensing data and a small sample of ground reference measurements enables to map Andean high altitude wetlands with high accuracies. BSVM was capable to classify the meadow areas with an overall accuracy of over ∼78% for both sensors. Our results also indicate that it is feasible to map surface soil moisture with optical remote sensing data and simple regression approaches in the examined environment. Surface soil moisture estimates reached r2 values of up to 0.58, and normalized mean square errors of 19% using Sentinel-2 data, while Worldview-2 estimates resulted in non-satisfying results. The presented approach is particularly valuable for monitoring high-mountain wetland areas with limited accessibility such as in the Andes.","publicationDate":"2018-01-01","doi":"10.1016/j.isprsjprs.2018.04.001","url":"https://andes.mountain-wetlands-repository.info/api/v1/items/71bbf73d-4811-40bd-ac3a-b4b3ebd69a77","timeperiod_startdate":null,"timeperiod_enddate":null,"placename":null,"country_code":null,"source_details":{"id":7,"name":"Mountain Wetlands Repository","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":"Mountain Wetlands Repository (MaRESS)","works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Araya Lopez","et al."],"keywords":["Wetland","Environmental science","Altitude (triangle)","Watershed","Remote sensing","Hydrology (agriculture)","Vegetation (pathology)","Land cover","Water content","Physical geography","Land use","Geography","Ecology","Geology"],"topics":["Soil Moisture and Remote Sensing","Remote Sensing in Agriculture","Soil erosion and sediment transport"],"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":"https://openalex.org/W2797446964","openalex_match_info":null,"openalex_fulltext_origin":"journal","openalex_is_retracted":false,"openalex_ids":{"doi":"https://doi.org/10.1016/j.isprsjprs.2018.04.001","mag":"2797446964","openalex":"https://openalex.org/W2797446964"},"openalex_open_access_status":null}},{"id":18,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[{"type":"Polygon","coordinates":[[[7.849731445312501,50.94804539355076],[8.135375976562502,50.90649688226162],[8.388061523437502,51.07937094724242],[8.651733398437502,51.16212186002124],[8.486938476562502,51.2928411273273],[8.695678710937502,51.51216124955517],[8.610534667968752,51.6469983484713],[8.324890136718752,51.681070878869825],[7.962341308593751,51.64018076739535],[7.775573730468751,51.56170488911645],[7.748107910156251,51.31516382328001],[7.594299316406251,51.29455864325789],[7.759094238281251,51.04657442107223],[7.849731445312501,50.94804539355076]]]}]},"bbox":[7.594299316406251,50.90649688226162,8.695678710937502,51.681070878869825],"properties":{"title":"The Digitalization of Local Owner-Operated Retail Outlets: How environmental and organizational factors drive the use of digital tools and applications","type":"article","abstract":"The digitalization of the retail industry is a disruptive innovation process which endangers the very existence of Local Owner Operated Retail Outlets (LOOROs).

While the urgent demand for automated pre-processing methods comes from various fields, it is still an unsolved challenge. In this article, we tackle this challenge by proposing a cheap computational heuristic for the identification of ``face artifacts, i.e., geometries that are enclosed by transportation edges but do not represent urban blocks. The heuristic is based on combining the frequency distributions of shape compactness metrics and area measurements of street network face polygons. We test our method on 131 globally sampled large cities and show that it successfully identifies face artifacts in 89% of analyzed cities. Our heuristic of detecting artifacts caused by data being collected for another purpose is the first step towards an automated street network simplification workflow. Moreover, the proposed face artifact index uncovers differences in structural rules guiding the development of cities in different world regions.","publicationDate":"2025-07-14","doi":null,"url":"https://service.tib.eu/komet/ojs330/index.php/gmdj/article/view/39","timeperiod_startdate":[null],"timeperiod_enddate":[null],"placename":null,"country_code":null,"source_details":{"id":9,"name":"geoMetadata Demo Journal","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":null,"works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Fleischmann","Martin"],"keywords":["JOSIS"],"topics":null,"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":null,"openalex_match_info":null,"openalex_fulltext_origin":null,"openalex_is_retracted":false,"openalex_ids":null,"openalex_open_access_status":null}},{"id":15,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[{"type":"Polygon","coordinates":[[[107.6349989,13.9096752],[107.6349989,22.5086717],[100.0843247,22.5086717],[100.0843247,13.9096752],[107.6349989,13.9096752]]]}]},"bbox":[100.0843247,13.9096752,107.6349989,22.5086717],"properties":{"title":"Goods and Ethnicity: Trade and Bazaars in Laos from a Gift Perspective; A Discussion","type":"article","abstract":"Drawing on ethnographic observations in Lao markets and bazaars, this article proposes a new and experimental framework for the analysis of multi-ethnic trading.

Both main minerals used for dating—quartz and K-rich feldspar—commonly have suboptimal luminescence properties when of volcanic origins, primarily a low signal intensity and, for K-rich feldspars, high rates of anomalous fading. The present work provides a case study of the Leang Bulu Bettue (LBB) archaeological site in Indonesia, a key site in our understanding of the early human occupation of the island of Sulawesi, showing that currently available state-of-the-art methods can provide robust chronologies for volcanic sediments. Through various reliability tests, we establish the suitability of a post-IR IR stimulated luminescence (pIRIR) standardised growth curve (SGC) procedure for De estimation of ‘micro-aliquots’ containing 5–10 grains of K-rich feldspar and apply these methods together with dose rate estimates to determine 10 new reliable finite ages for the sedimentary deposits at LBB. Further, by applying the LnTn method to circumvent truncation of the De distribution caused by the non-linearity of the dose response curve in the higher dose range, we could extend the site’s chronology to span ~20–210 ka. The new chronology is in keeping with previous radiocarbon and U-series ages for the site’s upper layers. We show that the low fading rate of micro-aliquots relative to using large aliquots composed of hundreds of grains lies in a brightness-based selection. By targeting bright grains with low fading rates, the need for fading corrections is greatly reduced and they can be made with a smaller uncertainty propagated through into the final age estimate, resulting in optical ages of improved accuracy and precision for volcanic sediments.","publicationDate":"2025-07-14","doi":null,"url":"https://service.tib.eu/komet/ojs330/index.php/gmdj/article/view/32","timeperiod_startdate":[null],"timeperiod_enddate":[null],"placename":"Kolaka, Sulawesi, Southeast Sulawesi, Indonesia","country_code":"ID","source_details":{"id":9,"name":"geoMetadata Demo Journal","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":null,"works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Sontag-González","Mariana"],"keywords":["EarthArXiv"],"topics":null,"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":null,"openalex_match_info":null,"openalex_fulltext_origin":null,"openalex_is_retracted":false,"openalex_ids":null,"openalex_open_access_status":null}},{"id":12,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[{"type":"Polygon","coordinates":[[[8.300314,56.5631286],[8.300314,56.6031286],[8.260314,56.6031286],[8.260314,56.5631286],[8.300314,56.5631286]]]}]},"bbox":[8.260314,56.5631286,8.300314,56.6031286],"properties":{"title":"Beach-ridge formation as a possible indicator for an open Limfjord – North Sea connection","type":"article","abstract":"Raised beach ridges are prograded sequences of wave-built deposits that may provide valuable information about past relative sea-level changes, climate change and coastal evolution.

The xenolith minerals compositionally overlap with phenocrysts from the volcanic rocks, but they also contain evidence for the presence of highly evolved melt compositions in the form of melt inclusions with extremely silica-rich compositions (up to 82 wt.% SiO2) and high enrichments of incompatible trace elements coupled with increasing negative Eu anomalies in clinopyroxenes. Since these characteristics correlate systematically with differentiation indices and rock type, they are interpreted to reflect melt evolution via fractional crystallisation as the dominant differentiation process with no significant role of reactive porous flow. These observations highlight that trapped melt fractions can influence mineral compositional variations in the plutonic xenoliths, and in turn the mineral compositions demonstrate a melt compositional variability not preserved in the volcanic rock record.","publicationDate":"2025-07-14","doi":null,"url":"https://service.tib.eu/komet/ojs330/index.php/gmdj/article/view/30","timeperiod_startdate":[null],"timeperiod_enddate":[null],"placename":"Thira Regional Unit, South Aegean, Greece","country_code":"GR","source_details":{"id":9,"name":"geoMetadata Demo Journal","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":null,"works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Whitley","Sean"],"keywords":["Volcanica"],"topics":null,"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":null,"openalex_match_info":null,"openalex_fulltext_origin":null,"openalex_is_retracted":false,"openalex_ids":null,"openalex_open_access_status":null}},{"id":10,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[{"type":"Polygon","coordinates":[[[24.145783,49.0020468],[24.145783,55.03605],[14.0696389,55.03605],[14.0696389,49.0020468],[24.145783,49.0020468]]]}]},"bbox":[14.0696389,49.0020468,24.145783,55.03605],"properties":{"title":"Analysis of the Housing Market Dynamics Using NARX Neural Network","type":"article","abstract":"This study employs a Nonlinear Autoregressive with eXogenous inputs (NARX) neural network to model the dynamics of the housing construction market in Poland, with a distinction made between segments of developers and individual investors.

Here, we examine the variation of parasitism across seasons and identify the likely climatic factors that explain this variation using Agriocnemis femina damselflies and Arrenurus water mite ectoparasites as host-parasite study system. We assessed parasitism in a natural population in a subtropical climate between 2021-2023 and calculated prevalence (percentage of infected individuals) and intensity (the number of parasites on an infected individual) of parasitism across different seasons. Parasite prevalence and intensity were greater during cooler seasons (autumn and winter) compared to hotter seasons (spring and summer). Mean temperature and precipitation were negatively correlated with parasite prevalence whereas only mean precipitation was negatively correlated with parasite intensity. Tropical, Subtropical and Mediterranean countries are predicted to experience extreme climatic events (extreme temperature, less precipitation and frequent drought) as a consequence of anthropogenic climate change, and our finding suggests that this could increase parasitism in aquatic insects.","publicationDate":"2025-07-14","doi":null,"url":"https://service.tib.eu/komet/ojs330/index.php/gmdj/article/view/28","timeperiod_startdate":[null],"timeperiod_enddate":[null],"placename":"Sylhet, Sylhet Sadar Upazila, Sylhet Division, Bangladesh","country_code":"BD","source_details":{"id":9,"name":"geoMetadata Demo Journal","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":null,"works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Kawsar Khan","Md"],"keywords":["EvoEcoArXiv"],"topics":null,"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":null,"openalex_match_info":null,"openalex_fulltext_origin":null,"openalex_is_retracted":false,"openalex_ids":null,"openalex_open_access_status":null}},{"id":8,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[{"type":"Polygon","coordinates":[[[7.3493347,51.4105176],[7.3493347,51.5313721],[7.1020817,51.5313721],[7.1020817,51.4105176],[7.3493347,51.4105176]]]}]},"bbox":[7.1020817,51.4105176,7.3493347,51.5313721],"properties":{"title":"Crowdsourcing air temperature data for the evaluation of the urban microscale model PALM—a case study in central Europe","type":"article","abstract":"In summertime and during heat events the urban heat island can negatively impact public health in urban areas. In the context of climate change, climate adaptation receives more attention in urban planning. Microscale urban climate modelling can identify risk areas and evaluate adaptation strategies. Concurrently, evaluating the model results with observational data is essential. So far, model evaluation is mostly limited to short-term field campaigns or a small number of stations. This study uses novel crowdsourcing data from Netatmo citizen weather stations (CWS) to evaluate the urban microscale model PALM for a hot day (Tmax ≥ 30 °C) in Bochum in western Germany with anticyclonic atmospheric conditions. Urban-rural air temperature differences are represented by the model. A quality control procedure is applied to the crowdsourced data prior to evaluation. The comparison between the model and the crowdsourced air temperature data reveals a good model performance with a high coefficient of determination (R2) of 0.86 to 0.88 and a root mean squared error (RMSE) around 2 K. Model accuracy shows a temporal pattern and night-time air temperatures during the night are underestimated by the model, likely due to unresolved cloud cover. The crowdsourced air temperature data proved valuable for model evaluation due to the high number of stations within urban areas. Nevertheless, weaknesses related to data quality such as radiation errors must be considered during model evaluation and only the information derived from multiple stations is suitable for model evaluation. The procedure presented here can easily be transferred to planning processes as the model and the crowdsourced air temperature data are freely available. This can contribute to making informed decisions for climate adaptation in urban areas.","publicationDate":"2025-07-14","doi":null,"url":"https://service.tib.eu/komet/ojs330/index.php/gmdj/article/view/27","timeperiod_startdate":[null],"timeperiod_enddate":[null],"placename":"Bochum, North Rhine-Westphalia, Germany","country_code":"DE","source_details":{"id":9,"name":"geoMetadata Demo Journal","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":null,"works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["van der Linden","Lara"],"keywords":["EarthArXiv"],"topics":null,"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":null,"openalex_match_info":null,"openalex_fulltext_origin":null,"openalex_is_retracted":false,"openalex_ids":null,"openalex_open_access_status":null}},{"id":7,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[{"type":"Polygon","coordinates":[[[-7.0327437,40.3806077],[-7.0327437,40.7009638],[-7.467313,40.7009638],[-7.467313,40.3806077],[-7.0327437,40.3806077]]]}]},"bbox":[-7.467313,40.3806077,-7.0327437,40.7009638],"properties":{"title":"A quantitative spatial methodology for delimiting historical centers - an application in Guarda, Portugal","type":"article","abstract":"A historical center can be defined as the oldest part of a city where a significant part of the building stock dates back to the early stages of urban growth. Historical centers often contain special urban fabrics with unique, historic, social and cultural identity. Owing to this, they have been subject to special urban planning interventions in order not only to protect the existing urban fabric and its originality, but also to revert depopulation and built deterioration processes aiming to make these old centers attractive and functional again. However, in the inter-urban domain, there is a deficit of spatial planning research, and the delimitation of historical centers is a topic that has been under explored. This paper describes a morphological approach for delimiting the historical center of Guarda, Portugal. Methodologically, the work uses building stock-age data from eight periods between <1919 to 2011 and is supported by both statistical and spatial analysis. Statistically, the urban evolution of the city was analyzed through threshold values and five novel building indexes. Spatially, the work involved disaggregated GIS analysis to map the evolution of built-up areas and to identify the consolidated urban areas. A sensitivity analysis was also performed to assess the influence of some parameters on the obtained boundary. Results indicated that the historical center of Guarda was consolidated in the 1960s and, since then, has been relatively unchanged. The obtained boundary shows a suitable spatial adjustment considering the consolidated urban area and the official boundary included in the Urban Rehabilitation Area. ","publicationDate":"2025-07-14","doi":null,"url":"https://service.tib.eu/komet/ojs330/index.php/gmdj/article/view/26","timeperiod_startdate":["1919-01-01"],"timeperiod_enddate":["2011-12-31"],"placename":"Guarda, Guarda, Portugal","country_code":"PT","source_details":{"id":9,"name":"geoMetadata Demo Journal","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":null,"works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Soares","Maria Elisabete"],"keywords":["JOSIS"],"topics":null,"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":null,"openalex_match_info":null,"openalex_fulltext_origin":null,"openalex_is_retracted":false,"openalex_ids":null,"openalex_open_access_status":null}},{"id":6,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[]},"properties":{"title":"Post-Brexit Power of European Union From the World Trade Network Analysis","type":"article","abstract":"We develop the Google matrix analysis of the multiproduct world trade network obtained from the UN COMTRADE database in recent years.

It is argued that older cultural styles and variations within local Islam have not disappeared, and that, more generally, characterizing the development of Indonesian Islam by using a single label is misleading. ","publicationDate":"2025-07-14","doi":null,"url":"https://service.tib.eu/komet/ojs330/index.php/gmdj/article/view/23","timeperiod_startdate":[null],"timeperiod_enddate":[null],"placename":"Sulawesi, Indonesia","country_code":"ID","source_details":{"id":9,"name":"geoMetadata Demo Journal","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":null,"works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Houben","Vincent"],"keywords":["heiJOURNALS"],"topics":null,"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":null,"openalex_match_info":null,"openalex_fulltext_origin":null,"openalex_is_retracted":false,"openalex_ids":null,"openalex_open_access_status":null}},{"id":3,"type":"Feature","geometry":{"type":"GeometryCollection","geometries":[{"type":"Point","coordinates":[16.415339112281803,48.27811289083328]}]},"bbox":[16.415339112281803,48.27811289083328,16.415339112281803,48.27811289083328],"properties":{"title":"First report of the parasitoid wasp Trissolcus basalis (Wollaston, 1858) in Austria (Hymenoptera: Scelionidae)","type":"article","abstract":"Im Sommer 2021 wurden parasitierte Eigelege der Grünen Reiswanze Nezara viridula (Linnaeus, 1758) in Wiener Privatgärten festgestellt.

It further shows that there is a subtle division of labor between the two kinds of constructions. It is proposed that the distributional difference between these two provides evidence in favor of the theories of conditionals that classify Hypothetical Conditionals and Biscuit Conditionals as having the same underlying semantics. Furthermore, it is shown that the distinction extends to the then-word tahole in the language. This leads to a pragmatic account of the conditional participle -le in different types of participial conditionals. The paper ends with discussing how a pragmatic account leads to an unresolved question regarding the syntactic classification of the conditionals.","publicationDate":"2025-07-14","doi":null,"url":"https://service.tib.eu/komet/ojs330/index.php/gmdj/article/view/20","timeperiod_startdate":[null],"timeperiod_enddate":[null],"placename":"Sreepur Upazila (Magura), Khulna Division, Bangladesh","country_code":"BD","source_details":{"id":9,"name":"geoMetadata Demo Journal","issn_l":null,"openalex_id":null,"openalex_url":null,"publisher_name":null,"works_count":null,"works_api_url":null,"default_work_type":"article"},"status":"p","status_display":"Published","authors":["Ishani Guha University of Delhi"],"keywords":["KIM"],"topics":null,"bok_concepts":null,"bok_concepts_resolved":[],"openalex_id":null,"openalex_match_info":null,"openalex_fulltext_origin":null,"openalex_is_retracted":false,"openalex_ids":null,"openalex_open_access_status":null}}]}}
