Global Patterns and Drivers of Freshwater Fish Extinctions: Can We Learn From Our Losses? [PDF]
Glob Chang BiolNearly one‐third of freshwater fish species are currently at risk of extinction, with 100 species already lost. This study examines extinction patterns over the past 165 years, identifying habitat modification and loss, pollution, and invasive species as key drivers.

Sexual Dimorphism in Fin Size and Shape in North American Killifish. [PDF]
Ecol EvolSexual dimorphism is pervasive in North American killifish in the size and shape of their dorsal and anal fins. These fins perform multiple functions, including grasping females during spawning, dominance displays towards rival males, and courtship towards females. Sexual selection may share a common direction across this group.

Disentangling the drivers of diversification in an imperiled group of freshwater fishes (Cyprinodontiformes: Goodeidae). [PDF]
BMC Evol Biol, 2018 One of the most perplexing questions in evolutionary biology is why some lineages diversify into many species, and others do not. In many cases, ecological opportunity has played an important role, leading to diversification along trophic or habitat-based axes.

Distribution and current conservation status of the Mexican Goodeidae (Actinopterygii, Cyprinodontiformes). [PDF]
Zookeys, 2019 The current distribution and abundance of the 40 species of Goodeidae fishes known from Mexico are described, and a total of 84 Evolutionarily Significant Units (ESUs) is designated within these species. Two species and four ESUs are likely extinct with no captive populations, and three species and eight ESUs are probably extinct in the wild but have ...

The complete mitogenome of the live-bearing fish Xenotoca variata (Bean, 1887) (Actinopterygii: Goodeidae). [PDF]
Mitochondrial DNA B Resour, 2017 The live-bearing fish Xenotoca variata is representative of the viviparous Goodeinae subfamily (Goodeidae) from central Mexico. The mitogenome of the X. variata consist of 37 genes in 16,462 bp. Comparing with X. eiseni, the most related of the mitogenomes included, an identity of 91.1% was found and trna-met duplication in X.

The invasive twospot livebearer's biology, and its current and potential global distribution
Journal of Fish Biology, Volume 103, Issue 5, Page 854-863, November 2023., 2023 Abstract Poeciliids are widely recognized as successful invaders, possessing traits associated with invasion success. Native to Central America and south‐eastern Mexico, the twospot livebearer (Pseudoxiphophorus bimaculatus) is a species recently recognized as invasive in both Central and northern Mexico.

Overlooked Invaders? Ecological Impacts of Non‐Game, Native Transplant Fishes in the United States
Fisheries, Volume 48, Issue 2, Page 62-71, February 2023., 2023 Nonnative fishes can cause ecological impacts as invasive species, but identifying which nonnative species have harmful impacts is critical to prioritizing management and policy responses. Here, we characterized the state of knowledge on the impacts of a possibly overlooked group of invasive species in the United States: non‐game native transplant ...

A global review of problematic and pathogenic parasites of farmed tilapia
Reviews in Aquaculture, Volume 15, Issue S1, Page 92-153, February 2023., 2023 Abstract Over the past 80 years, tilapia have been translocated globally for aquaculture; active production is recorded in >124 countries. Of 7 million tonnes of tilapia produced in aquaculture, 79% is from 79 countries outside the natural range of tilapia.
