Biological invasions are a population‐level rather than a species‐level phenomenon

Biological invasions pose a rapidly expanding threat to the persistence, functioning and service provisioning of ecosystems globally, socio-economic interests. The stages successful are driven by same mechanism that underlies adaptive changes across species in general-via natural selection on intraspecific variation traits influence survival reproductive performance (i.e., fitness). Surprisingly, however, rapid progress field invasion science has resulted predominance species-level approaches (such as deny lists), often irrespective theory, local adaptation other population-level processes govern invasions. To address these issues, we analyse non-native dynamics at population level employing database European freshwater macroinvertebrate time series, investigate spreading speed, abundance impact assessments among populations. Our findings reveal substantial variability speed trends within between biogeographic regions, indicating levels invasiveness differ markedly. Discrepancies inconsistencies risk screenings real data were also identified, highlighting inherent challenges accurately assessing effects through assessments. In recognition importance assessments, urge shift invasive management frameworks, which should account for different populations their environmental context. Adopting an adaptive, region-specific population-focused approach is imperative, considering diverse ecological contexts varying degrees susceptibility. Such could improve refine while promoting mechanistic understandings risks impacts, thereby enabling development more effective conservation strategies.

Non‐native species have higher consumption rates than their native counterparts

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Год журнала: 2025, Номер unknown

ABSTRACT Non‐native species can be major drivers of ecosystem alteration, especially through changes in trophic interactions. Successful non‐native have been predicted to greater resource use efficiency relative trophically analogous native (the Resource Consumption Hypothesis), but rigorous evidence remains equivocal. Here, we tested this proposition quantitatively a global meta‐analysis comparative functional response studies. We calculated the log ratio paired and responses, using attack rate maximum consumption parameters as variables. Explanatory variables were consumer taxonomic group feeding group, habitat, assemblage latitude, distinctiveness. Maximum rates for 70% higher, on average, than those their counterparts; also tended not significantly so. The magnitude effect sizes varied with being highest favour non‐natives molluscs herbivores. differences between freshwater taxa, perhaps reflecting sensitivity insular food webs novel consumers; pattern needs explored further additional data are obtained from terrestrial marine ecosystems. In general, our results support Hypothesis, which partly explain how successful reduce populations restructure webs.

The need of centralized coordination to counter biological invasions in the European Union

Environmental Sciences Europe, Год журнала: 2024, Номер 36(1)

Опубликована: Июль 8, 2024

Abstract Non-native species monitoring faces global challenges due to resource disparities, hindering effective implementation. Current strategies are fragmented and resource-dependent, inadequately addressing non-native dynamics subjected reporting biases, being further ridiculed by political borders. To overcome these challenges, a paradigm shift towards targeted, large-scale is crucial, requiring standardized protocols advanced technologies like environmental DNA analysis, orchestrated, applied—and enforced—following international collaboration. Despite existing efforts, networks, laws, even larger entities the European Union suffer from lack of information exchange as well economic, political, socio-cultural differences among member status, ultimately hampering united efforts against threat posed species. The absence comprehensive central hub authority, guided scientific input at same time empowered institution, emerges compelling solution. potential drawbacks, this possibly bridging gaps in approach, could coordinate standardize reporting, allocate resources, advocate increased funding. Considering rising introduction rates accelerating impacts species, creating centralized institution becomes imperative for enhancing management foster collaborative response threats.

Human-induced pressures have led to substantial changes in marine ecosystems worldwide, with the introduction of non-indigenous species (NIS) emerging as a significant threat ecological, economic, and social aspects. The Macaronesian islands, comprising Azores, Madeira, Canary Islands, Cabo Verde archipelagos, are regions where regional economy is dependent on resources (e.g., traffic, ecotourism fisheries).

Freshwater crayfish are amongst the largest macroinvertebrates and play a keystone role in ecosystems they occupy. Understanding global distribution of these animals is often hindered due to paucity distributional data. Additionally, non-native introductions becoming more frequent, which can cause severe environmental economic impacts. Management decisions related their habitats require accurate, up-to-date data mapping tools. Such currently patchily distributed with limited accessibility rarely up-to-date.

Spatial Scale and the Underestimation of Stream Fish Community Invadedness

Global Ecology and Biogeography, Год журнала: 2025, Номер 34(1)

Опубликована: Янв. 1, 2025

ABSTRACT Scale‐Dependency of Native Status Classifying populations as native or nonnative requires well‐defined range boundaries for species. While many studies define status according to large biogeographic realms, natural dispersal barriers often limit species distributions at regional smaller spatial extents. As such, native/nonnative definitions are inherently scale‐dependent and estimates community invadedness thus depend on the resolution which is defined. For example, can be introduced among regions within ecological provinces (hereafter, simply “provinces”). By explicitly considering scale‐dependency definitions, we more effectively compare results across studies, comprehensively evaluate degree invasion levels, objectively communicate a Location 30,034 stream segments, conterminous United States. Time Period 2000–2023. Major Taxa Studied Freshwater fishes. Quantifying Fish Community Invadedness Across US Streams We illustrate importance by quantifying richness relative abundance in fish communities States, finding that provincially nearly four times prevalent extra‐realm species, represented approximately 10% all individuals average surveys. Implications Unrealistically broad underestimate invadedness. Dismissing regionally have severe consequences, including displacement hybridisation with loss unique through biotic homogenisation. These consequences may undermine efforts maintain protect distinct local biodiversity conserve endemic

The Role of Non‐Native Plant Species in Modulating Riverbank Erosion: A Systematic Review

River Research and Applications, Год журнала: 2025, Номер unknown

Опубликована: Янв. 21, 2025

ABSTRACT Riverbank erosion is a naturally occurring process that influences riparian zone habitats. However, anthropogenic activities are increasing rates of riverbank erosion. Climate change and hydrological physical modifications drive perturbations. Whilst native vegetation can reduce erosion, the proliferation non‐native plant species has been linked to instability, with marked changes in fluvial erosional regimes attributed invasion by such as Impatiens glandulifera (Himalayan Balsam) or Tamarix (Tamarisk) into zones. Yet, role modulating remains unclear, part due lack investigations quantify geomorphic change. We systematically assessed relevant ecological geomorphological literature determine current understanding offer recommendations for future research on plant—riverbank Included articles focused limited number across restricted range habitats types, dependency topographic generally short study duration obscuring potential causal links feedback cycles.
