A global analysis of the introduction pathways and characteristics associated with non-native fish species introduction, establishment, and impacts

Ecological Processes, Journal Year: 2024, Volume and Issue: 13(1)

Published: March 12, 2024

Abstract Background The invasion success of introduced freshwater fishes is influenced by many factors, including ecological, species, and socioeconomic characteristics. Most studies that document the importance these characteristics are conducted at local scales and/or focus on a single step process. In this study, we aim to determine species characteristics, ecological non-native fish invasions. Our assessment was done global scale considers all three steps (i.e., introduction, establishment, impact). For purpose, applied generalized linear models 20 variables collected for 307 modeled them as function environmental features), traits functional morphological), human use introduction pathways). We considered number countries in which each introduced, established, or had impacts proxy success. also explored specifics through aquaculture ornamental trade pathways. Results found with broad diets, high parental care, multiple pathways most widely established worldwide. reported best explained type pathway fisheries). Moreover, among aquaculture, those belonging Cypriniformes having diets were species. contrast, belonged various taxonomic orders but mainly native tropical regions. Conclusions Considering several types factors important when analyzing disentangling different steps. These findings have strong implications anticipating profile potential invade countries.

Quantifying and Predicting the Spread of Established Non-Native Fishes in Peninsular Florida, USA

Biology, Journal Year: 2025, Volume and Issue: 14(2), P. 189 - 189

Published: Feb. 12, 2025

The spread of non-native species plays a substantial role in the designation as invasive, yet determination and measurement non-native-species is challenging, particularly for fishes, which are limited by aquatic connectivity. Spread has been quantified fishes variety ways exact methods vary region taxonomic group. In this study, we fish peninsular Florida used life history traits to understand what factors contribute rate at spread. Using statistical analyses, found that fast spreaders tend have larger body size, narrow diet, shorter time hatch, greater salinity tolerance, higher fecundity. However, some variables like parental care, egg diameter, reproductive guild were same or very similar across all established included analyses. Predicting whether an will quickly slowly may be more challenging than predicting introduced establish, there support regions use risk assessment process.

Climate Impacts on Lake Food‐Webs Are Mediated by Biological Invasions

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(3)

Published: March 1, 2025

ABSTRACT Climate change and biological invasions are among the most important drivers of biodiversity ecosystem change. Despite major advances in understanding their ecological impacts, these often considered individually, overlooking possible complex interrelationship. By applying structural equation modeling to an extensive nationwide dataset 430 fish communities across 257 French lakes, we investigated how taxonomic, size, trophic diversities impacted by climate warming exotic species occurrence. Our goal was compare relative signature or lasting impacts after factors had taken effect determine whether mediate current state community diversities. Drawing on a set interconnected hypotheses, suggest that could be indirect warming. This aspect must fully grasp overall effects change, beyond just its direct thermal impacts. results support our hypothesis negatively size However, mostly mediated warming‐induced increase richness, which, turn, promotes total richness. These have substantial role determining impact obscuring diversity patterns predicted temperature alone. We conclude cannot understood without considering via invasions, underscoring need intertwined roles predicting managing consequences.

Abstract This study investigates the temporal and spatial distribution of species richness in Turkish portions Euphrates Tigris catchments Mesopotamia, aiming to identify areas lacking sufficient research inform future conservation management efforts. Data from 153 fish assemblages catchment 100 catchment, spanning 1941 2022, were analysed using a combination analytical occurrence, space‐for‐time mixed effect models. Results indicate an increase reported over time, attributed heightened sampling efforts, reveal significant differences influenced by uneven environmental suitability. Identification with insufficient research, potential undetected biodiversity losses highlights need for improved assessments prevent unnoticed loss ecosystem degradation. Our results emphasize importance accurate effective interventions these catchments.

Responses of Showy Leopard Frog Larvae (Lithobates spectabilis) to the Presence of Introduced Rainbow Trout in Mexico

Aquatic Conservation Marine and Freshwater Ecosystems, Journal Year: 2024, Volume and Issue: 34(9)

Published: Sept. 1, 2024

ABSTRACT The introduction of invasive fish for aquaculture can significantly impact native aquatic fauna, especially in regions where amphibians have a biphasic life cycle. We conducted three laboratory experiments to assess the effects introduced rainbow trout ( Oncorhynchus mykiss ) on showy leopard frog Lithobates spectabilis Mexico. aimed understand visual and chemical cues tadpole behaviour, long‐term (in interaction with density) growth, development survival. In Experiment 1, we exposed groups tadpoles cue trout, comparing their refuge use position within tank control group. 2,we contrasting 3, at different densities prolonged period, recording Results showed that did not alter response but positioned themselves farther from these compared controls. Tadpoles increased cues. Long‐term exposure affect or survival, higher led lower survival rates. Our findings suggest farming, through escapement untreated farm water discharge containing cues, could trigger behavioural responses L. larvae, increasing local densities, ultimately compromising and, potentially, species persistence.

ABSTRACT While biological invasions continue to threaten biodiversity, most of current assessments focus on the sole exposure invasive alien species (IAS), without considering native species' response threat. Here, we address this gap by assessing vertebrates' vulnerability invasions, combining measures both (i) 304 identified IAS and (ii) realized sensitivity 1600 vertebrates We used IUCN Red List Threatened Species identify threatened IAS, their distribution, range characteristics associated IAS. found that 38% worldwide terrestrial lands are exposed but alone was insufficient assess since further world hosted sensitive invasions. delineated areas highly vulnerable is, high located in Australia coastal states North America with a confidence level, also—depending group—in Pacific islands, Southern America, Western Europe, Africa, Eastern Asia, New‐Zealand medium level. Assessing completeness data, revealed strong biases global description well‐known invasion hotspots, limited being assessed The overall very high, for three studied taxonomic groups. also demonstrated coldspots were low terms data completeness, which coincided biodiversity hotspots. There is thus critical need these knowledge shortfalls jeopardize efficient conservation initiatives, regarding threats vertebrate taxa.
