Ecology and Evolution, Volume 15, Issue 9, September 2025.We find support for a benthic origin of sharks, with four discrete transitions towards pelagic‐type morphology occurring during the Jurassic and Cretaceous. Increased habitat availability driven by biotic and abiotic environmental change may have driven shifts towards pelagic‐type morphology. These results may help explain discordance between molecular

Journal of Biogeography, Volume 52, Issue 9, September 2025.ABSTRACT Aim How communities of organisms come together has long fascinated scientists, with renewed interest in using functional and evolutionary patterns to infer mechanisms of community assembly. Ecological theory predicts that biotic interactions could lead to either divergence in the event of niche partitioning or convergence through the exclusion

Dopaminergic Neurons in the Zebrafish Subpallium Belong to the Extended Medial Amygdala
Journal of Comparative Neurology, Volume 533, Issue 8, August 2025.We identify directly adjacent to the pallial–subpallial boundary a pax6a‐negative dorsal Vdd2 portion of the zebrafish larval subpallium that develops into the extended medial amygdala (EMeA). Zebrafish subpallial dopaminergic neurons that locate to Vdd2 belong to the EMeA and form a heterogeneous group differentially expressing calbindin2a and ...

Sex Differentiation and Long‐Distance Gene Flow in the Elusive Antarctic Fish Aethotaxis mitopteryx
Ecology and Evolution, Volume 15, Issue 8, August 2025.This genetic study of a rare Antarctic fish, the longfin icedevil (Aethotaxis mitopteryx) investigates population connectivity across the Weddel Sea, revealing little to no differentiation even over vast geographic distances. Unexpectedly, the strongest genetic differentiation is instead observed between male and female fishes, which suggests a ...

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 8, August 2025.Abstract Mountain building reorganizes drainage networks, influencing riverine biodiversity. Northern Italy offers a natural experiment in the impact of tectonic and geomorphic processes on aquatic species distribution. We combined geomorphic analysis with environmental DNA from rivers to assess the influence of tectonically driven drainage ...

A Global Account of Established Non‐Native Fish Species
Global Change Biology, Volume 31, Issue 8, August 2025.This study compiles the most complete global database of non‐native fish species that have successfully established themselves in new freshwater and marine environments. It documents 1535 species across 193 countries, identifies their main introduction routes—such as aquarium trade, aquaculture, and artificial waterways—and highlights that many ...

New records of fishes (Actinopterygii: Ostariophysi) from the Upper Tapajós River Basin
Check List, 2012 The first report of Sartor (Anostomidae) and Tatia intermedia (Auchenipteridae) for the Upper Tapajós River Basin are presented here. Sartor is very rare on collections, and is reported only from the Trombetas, Tocantins and Upper Xingu river basins. Tatia intermedia is registered in the upper reaches of the Araguaia, Tocantins, Xingu, and Capim rivers,

Fishes (Osteichthyes: Actinopterygii) from igarapés of the rio Acre basin, Brazilian Amazon
Check List, 2013 This study presents a list of species from igarapés tributaries of the rio Acre, Acre State, Brazil. Fish assemblages were sampled in October 2009, August and October 2010, using standard ichthyological gear, along fifteen sampling sites. A total of 11,395 specimens, distributed in 94 species, 24 families and six orders were collected. The most species-

Multiple Origins of Sex Chromosomes in Nothobranchius Killifishes
Molecular Ecology, Volume 34, Issue 16, August 2025.ABSTRACT Sex chromosomes have evolved repeatedly across eukaryotes. The emergence of a sex‐determining (SD) locus is expected to progressively restrict recombination, driving convergent molecular differentiation. However, evidence from taxa like teleost fishes, representing over half of vertebrate species with unmatched diversity in SD systems ...
