Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River. [PDF]

open access: yesConserv Biol
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Linking rivers, mixing faunas: How artificial connectivity between the Middle and Upper Paraná River basins shapes fish diversity in a tributary of the Itaipu Reservoir, Brazil. [PDF]

open access: yesJ Fish Biol
Abstract This work aimed to investigate the distribution and occurrence of fish species along the São Francisco Falso Braço Norte (SFFBN) River basin, a tributary of the Middle Paraná River basin now artificially connected to the Upper Paraná ecoregion, to evaluate how such connectivity may affect the biogeographic distribution and regional composition

Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling. [PDF]

open access: yesMol Ecol
ABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

A Global Account of Established Non-Native Fish Species. [PDF]

open access: yesGlob Chang Biol
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 ...

Female mating preferences in blind cave tetras Astyanax fasciatus (Characidae, Teleostei). [PDF]

open access: yes, 2006
The Mexican tetra Astyanax fasciatus has evolved a variety of more or less color- and eyeless cave populations. Here we examined the evolution of the female preference for large male body size within different populations of this species, either surface-

On the habitat and isolation of Gymnocharacinus bergi (Osteichthyes: Characidae) [PDF]

open access: yesEnvironmental Biology of Fishes, 1995
Gymnocharacinus bergi is a rare Paranensean fish which is the only characiform almost lacking scales in the adult. It is endemic and the only species in a peculiar spot — a tributary of the Valcheta creek — in the Somuncura plateau in northern Patagonia, Argentina, over 300 km from the nearest place with a paranensean fish fauna.

Sperm phylogeny of Characidae (Teleostei, Characiformes)

open access: yesZoologica Scripta, 2022
AbstractThe phylogeny of the very diverse Neotropical fish family Characidae has been the subject of several recent contributions based on morphological characters, molecular data or both in combined analyses. In cases of conflict between these kinds of data, resolution by combined analyses most often tends to agree with the molecular evidence, given ...
