TLDR
The present study provides an illustrative conspectus of the most recent literature reporting ecological impacts of non-native freshwater fishes from a wide range of species and geographic locations and concludes with a prospectus of needed areas of scientific inquiry.Abstract:
There is a long history of introduction of non-native fishes in fresh waters and the introduction rate has accelerated greatly over time. Although not all introduced fishes have appreciable effects on their new ecosystems, many exert significant ecological, evolutionary, and economic impacts. For researchers, managers, and policy makers interested in conserving freshwater diversity, understanding the magnitude and array of potential impacts of non-native fish species is of utmost importance. The present study provides an illustrative conspectus of the most recent literature reporting ecological impacts of non-native freshwater fishes from a wide range of species and geographic locations and concludes with a prospectus of needed areas of scientific inquiry. Both directly and indirectly, invasive fishes affect a wide range of native organisms from zooplankton to mammals across multiple levels of biological organizations ranging from the genome to the ecosystem. Although a great deal of knowledge ha...read more

Non-native species promote trophic dispersion of food webs
TL;DR: The study of pollutant cycling and bacterial response to organic pollutants will improve current riverine pollution remediation strategies and management tools and provide insights for possible bioremediation strategies.
Journal ArticleDOI
Response diversity, nonnative species, and disassembly rules buffer freshwater ecosystem processes from anthropogenic change.
TL;DR: In this article, the authors examined the response of freshwater fishes and their nutrient excretion to human land development across the contiguous United States and found that the more tolerant species were also the species contributing greater ecosystem function.

The use of barriers to limit the spread of aquatic invasive animal species: a global review

TL;DR: In this article, the authors conducted a quantitative literature review to evaluate the use of barriers to control aquatic invasive species (AIS) in freshwater ecosystems worldwide The quantitative aspect of the review was supplemented by case studies that describe some of the challenges, successes, and opportunities for the application of AIS exclusion barriers globally and highlight the pressing need for AIS control in many ecoregions.

Multi‐trophic impacts of an invasive aquatic plant
TL;DR: Given the effects observed across multiple habitat characteristics and biota, parrotfeather appears to be a highly impactful invader where it establishes and managers should specifically consider contrasting characteristics between non-native and native physical structure when assessing and prioritising threats of invasive macrophytes.
Journal ArticleDOI
Invasive Apple Snail Diets in Native vs. Non-Native Habitats Defined by SIAR (Stable Isotope Analysis in R)
TL;DR: Invasive apple snails adversely impact the ecological function of non-native habitats, resulting in eutrophication as well as reduced biodiversity, which diminishes ecosystem goods and services, thereby [negatively] impacting human well-being as discussed by the authors .

TL;DR: This article explores the special features of freshwater habitats and the biodiversity they support that makes them especially vulnerable to human activities and advocates continuing attempts to check species loss but urges adoption of a compromise position of management for biodiversity conservation, ecosystem functioning and resilience, and human livelihoods.

Extinction by hybridization and introgression
TL;DR: Nonindigenous species can bring about a form of extinction of native flora and fauna by hybridization and introgression either through purposeful introduction by humans or through habitat modification, bringing previously isolated species into contact.

Impact: Toward a Framework for Understanding the Ecological Effects of Invaders

TL;DR: This paper argues that the total impact of an invader includes three fundamental dimensions: range, abundance, and the per-capita or per-biomass effect of the invader, and recommends previous approaches to measuring impact at different organizational levels, and suggests some new approaches.

TL;DR: This work explores the nature of these recent biotic exchanges and their consequences on evolutionary processes, and shows how flexibility in behavior, and mutualistic interactions, can aid in the success of invaders in their new environment.

The problems with hybrids: setting conservation guidelines
TL;DR: This work provides a categorization of hybridization to help guide management decisions and recognizes that nearly every situation involving hybridization is different enough that general rules are not likely to be effective.
