Invasive non-native species are an important cause of biodiversity loss, particularly in fresh waters. The mosquitofish Gambusia holbrooki are among the world’s worst invasive spe…

Invasive species pose a significant threat to ecological systems, impacting biodiversity and ecosystem functioning. Invasive plants and bees can alter mutualistic networks by incr…

Facultative paedomorphosis is a widespread polyphenism in newts and salamanders, but it is declining due to the introduction of non-native species. Conversely, caudates have often…

Recent declines in the population size and habitat of the native European Impatiens noli-tangere have led to its observed disappearance. The spread of the North American I. capens…

The life-history traits of fish are influenced by numerous factors, including parasitic infections. Parasites can significantly impact host mortality, growth performance, and repr…

Human activities have been transporting caprellid amphipods (or “skeleton shrimps”) across the oceans for many decades. As a result, some caprellid amphipods now are among the mos…

The invasive ambrosia beetle Euwallacea fornicatus (Eichhoff, 1868) poses a significant threat to forests sensu latu in South America. Uruguay marked the third regional record sin…

There is increasing concern that the effects of biological invasions may be magnified by other human-induced global changes. Here, we compare the non-consumptive effects imposed b…

Studying the coexistence of native species and invasive species with similar functional traits, habitat usage, and feeding habits is crucial for understanding the dynamics of inva…

The “bloody-red shrimp” species Hemimysis anomala, native to the Ponto-Caspian Region, has spread rapidly and adapted over recent decades to new aquatic ecosystems worldwide, caus…

The number of alien species continues to climb uninterrupted with a proportion of them becoming invasive, impacting native biodiversity and socioeconomic parameters. Many alien sp…

Although understanding the relationship between the reproductive mode and mass-dispersal potential of plants is crucial for studying invasion phenomena, the morphological features…

Estuarine ecosystems are often characterised by endemic foundation organisms which facilitate ecosystem interactions and processes established over millennia. Introduction of non-…

Introductions of non-native species (NNS) are major drivers of biodiversity loss. Gammarids (Crustacea, Gammaroidea) have been particularly successful in establishing and spreadin…

Invasive alien (IA) predators pose significant threats to native ecosystems, often leading to profound impacts on prey species through both direct and non-consumptive effects (NCE…

Plant material of invasive alien plant species (IAPS) must be appropriately disposed of to prevent unintended spread. The current guidelines in Slovenia and in several other Europ…

Climate warming can modify the process of biological invasions by affecting the outcomes of competition between alien species and their native counterparts in invaded environments…

The success of invasive species can be measured by invasiveness, which depicts intrinsic characteristics that enable them to thrive in new environments. In invasive seaweeds, for …

Ambrosia artemisiifolia is a serious threat to human health and agricultural yield. Due to its annual growth form management should focus on the prevention of seed production in t…

Understanding how some introduced plants achieve invasive status while most simply become naturalized is a fundamental question in invasion ecology. Traditional approaches compari…

Invasive insects threaten ecosystem stability, public health, and food security. Documenting newly invasive species and understanding how they reach into new territories, establis…

Invasive alien plants cause severe global problems; therefore, determining the factors that lead to the success or failure of invasion is a critical question in the field of invas…

Losses in crop yield due to invasive insects, weeds, pathogens, and herbivores cost trillions of dollars per year globally. To prevent further spread of invasive agricultural pest…

Unionid mussels are globally threatened by several human disturbances, including the introduction of non-native species. Among these, biofouling zebra and quagga mussels of Ponto-…

Insect pest species are generally expected to become more destructive with climate change because of factors such as weakened host tree defences during droughts and increased volt…

The invasive fish, Amur sleeper, poses a significant and growing threat to Central European freshwater ecosystems. Despite its rapid spread, the ecological implications of its inv…

Allee effects are density-dependent barriers that can impact species establishment and population growth, such as through reduced mating success at low population densities. The e…

Ambrosia trifida (giant ragweed) is an invasive species that causes habitat destruction and competitively excludes native plants in many parts of Europe and Asia. In this study, w…

1. Ecosystem engineering freshwater bivalves, burrowing in the substratum and accumulating shell deposits, transform bottom habitats. Especially the invasive Asian bivalve Sinanod…

The invasive mosquito species Aedes albopictus (Skuse, 1894) is rapidly spreading in Europe, posing an increasing threat because of its high vector competence for chikungunya and …

Although belowground invasive species are probably equally widespread and as important as their aboveground counterparts, they remain understudied, and their impacts are likely to…

Invasive species pose a major threat to natural ecosystems and directly outcompete many native species, placing them at imminent threat of extinction. The topmouth gudgeon (Pseudo…

Determining the consumptive effects of non-native predators, for which several direct and indirect methods have been applied, is a common goal in invasion biology. Functional resp…
