Freshwater Fish Invasions: A Comprehensive Review

Annual Review of Ecology Evolution and Systematics, Journal Year: 2022, Volume and Issue: 53(1), P. 427 - 456

Published: Sept. 3, 2022

Freshwater fish have been widely introduced worldwide, and freshwater ecosystems are among those most affected by biological invasions. Consequently, invasions one of the documented animal taxa, with much information available about invasive species, their characteristics, invaded regions, invasion pathways, impacts, management. While existing reviews address specific aspects invasions, there is still a gaping lack comprehensive assessments that simultaneously pivotal connected elements process. Here, we provide holistic review, together quantitative assessments, divided into four major parts: ( a) introduction b) characteristics nonnative species andinvaded explain successful processes, c) impacts mechanisms, d) We highlight data gaps biases in current databases basic understanding several In addition, recommendations for future studies.

Biotic homogenisation and differentiation as directional change in beta diversity: synthesising driver–response relationships to develop conceptual models across ecosystems

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2023, Volume and Issue: 98(4), P. 1388 - 1423

ABSTRACT Biotic homogenisation is defined as decreasing dissimilarity among ecological assemblages sampled within a given spatial area over time. differentiation, in turn, increasing Overall, changes the dissimilarities (termed ‘beta diversity’) an increasingly recognised feature of broader biodiversity change Anthropocene. Empirical evidence biotic and differentiation remains scattered across different ecosystems. Most meta‐analyses quantify prevalence direction beta diversity, rather than attempting to identify underlying drivers such changes. By conceptualising mechanisms that contribute or composition space, environmental managers conservation practitioners can make informed decisions about what interventions may be required sustain predict potential outcomes future disturbances. We systematically reviewed synthesised published empirical for terrestrial, marine, freshwater realms derive conceptual models explain diversity. pursued five key themes our review: ( i ) temporal change; ii disturbance regime; iii connectivity alteration species redistribution; iv habitat v trophic interactions. Our first model highlights how occur function local (alpha) diversity regional (gamma) independently invasions losses due occurrence assemblages. Second, magnitude depends on interaction between variation (patchiness) (synchronicity) events. Third, context redistribution, divergent have dispersal characteristics, associated with also strongly alpha gamma prior invasion. Fourth, positively linked variability, when heterogeneity decreases increases, respectively. Fifth, interactions influence via modification, disease, consumption (trophic dynamics), competition, by altering ecosystem productivity. synthesis multitude cause more less spatially similar (taxonomically, functionally, phylogenetically) through consider studies should aim enhance collective understanding systems clarifying driving focusing only reporting per se .

The Use of Barriers to Limit the Spread of Aquatic Invasive Animal Species: A Global Review

Frontiers in Ecology and Evolution, Journal Year: 2021, Volume and Issue: 9

Published: Feb. 9, 2021

Aquatic invasive species (AIS) are one of the principal threats to freshwater biodiversity. Exclusion barriers increasingly being used as a management strategy control spread AIS. However, exclusion can also impact native organisms and their effectiveness is likely be context dependent. We conducted quantitative literature review evaluate use animal AIS in ecosystems worldwide. The aspect was supplemented by case studies that describe some challenges, successes, opportunities for globally. Barriers have been since 1950s AIS, but effort has increasing 2005 (80% studies) an diverse range taxa now targeted wide habitat types. global concentrated North America (74% studies), Australasia (11%), Europe (10%). Physical (e.g., weirs, screens, velocity barriers) most widely (47%), followed electric (27%) chemical (12%). Fish were (86%), crustaceans (10%), molluscs (3%) amphibians (1%). Most moderately successful limiting passage with 86% tested deterring >70% individuals. only 25% evaluated barrier impacts on species, development selective still its infancy. too short (47% < 1 year, 87% 5 years) detect ecological or failed robust before-after-control-impact (BACI) study designs (only 5%). Hence, more effective monitoring required assess long-term tool.

Anthropogenic influences reshape lentic fish diversity: Patterns of homogenization and differentiation across a Mediterranean biodiversity hotspot

The Science of The Total Environment, Journal Year: 2025, Volume and Issue: 973, P. 179154 - 179154

Published: March 20, 2025

Freshwater ecosystems are increasingly impacted by human activities, resulting in species invasions and extinctions, disrupting biodiversity ecosystem functions. This study investigates the patterns of taxonomic functional homogenization differentiation fish assemblages within 103 lentic across a Mediterranean hotspot (Greece). We focus on how non-native have altered diversity at both national ecoregional levels while exploring drivers pathways behind these changes. Our analysis combined historical current data, evaluating effects introductions local extinctions distinct freshwater ecoregions. calculated similarities using Jaccard Gower dissimilarity indices employed generalized linear models (GLMs) to assess significance changes over time. Results reveal significant ecosystems, primarily driven introduction widespread alien translocated species. In contrast, was less pronounced, with some regions exhibiting differentiation, including increases richness due ecological traits. Non-native introduced through angling, ornamental trade, unintentional were primary contributors homogenization. The findings highlight prominent regional differences vulnerabilities: mainland ecoregions experienced stronger homogenization, insular differentiation. Additionally, reveals decoupling changes, emphasizing need consider assessments conservation management. research contributes broader understanding reshape functions systems. approach provides useful framework for assessing biotic implications management strategies worldwide.

Published: Oct. 26, 2022

Abstract Anthropogenic impacts on biodiversity can lead to biotic homogenization (BH) and differentiation (BD). BH is a process of increasing similarity in community composition (including taxonomic, functional, phylogenetic components), whereas BD decreasing over space time. Here, we conducted systematic review plant communities tropical subtropical forests identify trends knowledge gaps. Our bibliometric search the Web Science returned 1989 papers, which 151 matched our criteria were included analysis. The Neotropical region had largest number articles, Brazil was most represented country with 92 studies. Regarding type change, more frequent than (noted 69.6% publications). taxonomic diversity component measured often functional components. Most studies (75.6%) assessed based single observation time; as opposed few that monitored multiple years. Forest fragmentation cited main determinant processes (57.2% articles). results highlight importance evaluating time components (i.e., phylogenetic) advance understanding differentiation. Both scale dependent not mutually exclusive. As such, future research should consider potential transition phase differences both may depend spatial temporal adopted. Understanding complexity causes essential for conservation world increasingly affected by anthropogenic disturbances.

Diversity and Distributions, Journal Year: 2023, Volume and Issue: 29(11), P. 1492 - 1507

Published: Sept. 25, 2023

Abstract Aim Analysing the spatio‐temporal patterns and dynamics of non‐native species is essential to understanding mechanisms underlying successful invasions developing effective management strategies. Yet, such analyses generally neglect influence receiving ecosystem types sources (i.e. alien species, non‐natives originating outside concerned region; translocated introduced locations their historical range within region). Location Yunnan, China. Methods We analysed long‐term (1950–2022) potential fishes in a biodiversity hotspot (Yunnan, China), paying special attention waterbody comparing species. did this through compiling highly comprehensive occurrence dataset native fishes. Results recorded 783 94 (49 45 species), which mainly belonged order Cypriniformes (52 species) were via purposes for advancing aquaculture. Most frequently encountered either intentionally aquaculture or small‐bodied fish unintentionally activities. The richness spatial ranges increased consistently since 1950s demonstrated pronounced change after 2000s, with densely populated areas middle lower reaches large rivers being more profoundly affected. number records exceeded 2000s. Lakes reservoirs are hotspots both introductions, watersheds Yunnan (e.g. Jinsha‐Yangtze Lancang‐Mekong basins) contained fish. Main Conclusions Our study highlights need consider invasion sensitivities ecosystems pay intra‐regional translocations when prevention strategies against particularly important around world.
