Metagenomic analysis of Raphidiopsis raciborskii microbiome: beyond the individual
Raphidiopsis raciborskii is a toxic, invasive bacteria with a defined biogeographic pattern attributed to the generation of ecotypes subjected to local environmental filters and t…
Mating marks on museum specimens reveal breeding patterns in species of Pterostichus Bonelli (Carabidae, Pterostichini)
We found distinct and consistently placed, species- and sex-specific abrasions of the cuticle on museum specimens of 14 species of the Pterostichus Bonelli, 1810 (Carabidae, Ptero…
Revision of the Exechia parva group (Diptera: Mycetophilidae)

Here, we describe BIOVERA-Tree, a database on tree diversity, community composition, forest structure, and functional traits collected in 120 forest plots distributed along an ext…
Revison of Metaplagia Coquillett (Diptera: Tachinidae) with description of five new species from Area de Conservación G…
We revise the genus Metaplagia Coquillett, 1895 and describe five new species from Area de Conservación Guanacaste (ACG) in northwestern Costa Rica. All new species were reared fr…
New distributional records for ants and the evaluation of ant species richness and endemism patterns in Mexico
Ants (Formicidae) in Mexico have been usually undersampled despite their ecological significance and their utility as service providers and bioindicators. This study estimates the…
Patterns of richness, diversity and abundance of an odonate assemblage from a tropical dry forest in the Santiago Domin…
A study on the patterns of richness, diversity and abundance of the Odonata from Santiago Dominguillo, Oaxaca is presented here. A total of 1601 specimens from six families, 26 ge…
Effects of stream permanence on stonefly (Insecta, Plecoptera) community structure at Mammoth Cave National Park, Kentu…
Stoneflies (Plecoptera) are often associated with inhabiting cold perennial streams, but many species also inhabit intermittent streams that experience reduced or lack of flow dur…
Diversity patterns of free-living nematode assemblages in seagrass beds from the Cuban archipelago (Caribbean Sea)
Diversity patterns of free-living marine nematodes in tropical seagrass beds are understudied. Here, we describe the species richness and assemblage composition of nematodes in 13…
Species richness and biogeographical affinities of the marine molluscs from Bahía de Chamela, Mexico
For more than 10 years (2007-2018), the benthic macroinvertebrates of Bahía de Chamela (Mexican Pacific) were sampled at 31 sites (0-25 m depth). A total of 308 species of the fiv…
Additions to the “Martian Flora”: new botanical records from the Mars Desert Research Station, Utah
The Mars Desert Research Station (MDRS) is a Mars-simulation campus set in a Martian planetary analogue in southern Utah. Despite a long history of astrobiology research, collecti…
Surveys in northern Utah for egg parasitoids of Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) detect Trissolcus ja…
The highly polyphagous and invasive brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), has become a significant insect pest in North America since its…
Natural history of the social millipede Brachycybe lecontii Wood, 1864
The millipede Brachycybe lecontii Wood, 1864 is a fungivorous social millipede known for paternal care of eggs and forming multi-generational aggregations. We investigated the lif…
A fortuitous find: a unique haplotype of Ooencyrtus nezarae Ishii (Encyrtidae: Encyrtinae) discovered in Florida
The adventive arrival of biological control agents circumvents the regulatory process by introducing exotic species to control invasive pests and is generally followed by post hoc…
Monogonot rotifers species of the island Cozumel, Quintana Roo, México
The current study adds 23 new records to the previously described monogonot rotifers of Cozumel, increasing the number of reported species to 40; these species are grouped into tw…
First record of Xestochironomus Sublette and Wirth, 1972 (Chironomidae: Chironominae) in the Mexican Nearctic with note…
We report the first record of Xestochironomus Sublette and Wirth, 1972 for the Mexican Nearctic. Larvae of Xestochironomus are known from the Neotropics and Nearctic regions. We r…
Evaluation of the population dynamics of microalgae isolated from the state of Chiapas, Mexico with respect to the nutr…
As Chiapas state, México, counts on an extensive hydrography with diverse nutrimental and climatic characteristics, it therefore allows isolating and identifying microalgae with b…
Effects of a recalcitrant understory fern layer in an enclosed tropical restoration experiment
Establishing mixed-species tree plantings and fencing them to protect seedlings from herbivory is a valuable strategy for reconnecting forest fragments separated by agropastoral l…
Do dense layers of invasive plants elevate the foraging intensity of small mammals in temperate deciduous forests? A ca…
Monospecific stands of invasive plants can dramatically restructure habitat for fauna, thereby elevating population densities or promoting foraging of consumer species who benefit…
Context-dependent differences in the functional responses of conspecific native and non-native crayfishes
Invasive species are proliferating globally and cause a range of impacts, necessitating risk assessment and prioritization prior to management action. Experimentally derived estim…
Effects of osmotic and thermal shock on the invasive aquatic mudsnail Potamopyrgus antipodarum: mortality and physiolog…
Invasive freshwater species, such as the exotic mollusc Potamopyrgus antipodarum (New Zealand mudsnail), can frequently survive under harsh conditions, including brackish and hypo…
Unravelling the origin and introduction pattern of the tropical species Paracaprella pusilla Mayer, 1890 (Crustacea, Am…
Paracaprella pusilla Mayer, 1890 is a tropical caprellid species recently introduced to the Eastern Atlantic coast of the Iberian Peninsula and the Mediterranean Sea. In this stud…
The dark side of facilitation: native shrubs facilitate exotic annuals more strongly than native annuals
Positive interactions enhance biodiversity and ecosystem function, but can also exacerbate biological invasions. Facilitation of exotic invaders by exotic foundation species (inva…
Comparing functional traits and abundance of invasive versus native woodwasps
Functional traits are useful for comparing the resource use of invasive and native species, with goals of identifying resource overlap to predict competitive interactions. The inv…
Importance of soil and plant community disturbance for establishment of Bromus tectorum in the Intermountain West, USA
The annual grass Bromus tectorum has invaded millions of hectares in western North America and has transformed former perennial grass and shrub-dominated communities into annual g…
Collapse of a reproducing population of non-native African jewelfish (Hemichromis letourneuxi) in a Florida lake
Established populations of non-natives may collapse without a clear causal mechanism. Hypothetically, fluctuations in habitat structural complexity may influence dynamics of invad…
Distribution and abundance of exotic earthworms within a boreal forest system in southcentral Alaska

Comparing functional similarity between a native and an alien slug in temperate rain forests of British Columbia
The impacts of invasive alien species are greatest when they become dominant members of a community, introduce novel traits, and displace native species. Invasions by alien mollus…
