Non‐native fishes are often blamed for exerting adverse ecological impacts on native fishes,
but the evidence is circumstantial and the true impacts remain largely unknown. This …

The current freshwater fish fauna crisis is such that natural resource managers urgently
need to identify priorities and understand the management consequences of actions aimed …

Stable isotope analyses have emerged as an insightful tool for ecologists, with quantitative
methods being developed to analyse data at the population, community and food web …

Microplastic pollution and ingestion are ubiquitous phenomena in freshwater ecosystems.
However, our understanding of the role of trophic niche in microplastic ingestion is still …

Statistical mixing models have been developed to help ecologists deal with isotope tracer
data and to estimate source contributions in complex systems such as food webs and …

Ecological theory attempts to predict how impacts for native species arise from biological
invasions. A fundamental question centres on the feeding interactions of invasive and native …

Aim Exotic species invasion often leads to declines in local and regional biodiversity,
particularly in freshwater ecosystems. This biodiversity loss is generally facilitated by human …

When invasive species become integrated within a food web, they may have numerous
direct and indirect impacts on the native community by creating novel trophic links, and …

Biological invasions exert multiple pervasive effects on ecosystems, potentially disrupting
species interactions and global ecological processes. Our ability to successfully predict and …

Introduced non-native fishes can cause considerable adverse impacts on freshwater
ecosystems. The pumpkinseed Lepomis gibbosus, a North American centrarchid, is one of …
