Changes in parasite communities of fishes from an intermittent river in the Brazilian semi-arid, after a major interbasin water transfer
Rivers interlinking by transposition projects have multiplied in the world, altering the landscape and flow regime of continental water systems....

Upstream movement of juvenile eels (Anguilla anguilla L.) in a southwestern European river
The upstream movement of juvenile eels (median total length (TL) = 138 mm) in the Mondego River, Portugal, was analysed between January 2017 and...

Is the São Francisco River a historical barrier to gene flow for populations of Melipona mandacaia Smith, 1863 (Hymenoptera: Apidae)?
AbstractLarge rivers are usually associated with vicariance and diversification of terrestrial species, but little is known about these effects in...

Beyond just a dam blockage problem: larger artificial reservoirs are additional obstacles to reproductive fish migration in the Neotropics
One of the most conspicuous impacts of dam construction on fish is the blocking of their migratory routes. However, the formation of the reservoir, a...

Influences of small hydroelectric power plants on homogenization of the ichthyofauna in a tropical river
The native fishes of the Neotropical region have been heavily impacted by the construction of reservoirs that block the rivers in different degrees....

Influence of species invasion, seasonality, and connectivity on fish functional and taxonomic beta-diversity in a Neotropical floodplain
Studies that combine functional and taxonomic beta-diversity are essential for explaining some ecological processes, including the process of species...

The decline of the ecosystem services generated by anadromous fish in the Iberian Peninsula
This work aims to present an historical review of the ecosystem services provided by anadromous fish (i.e., species that migrate from the sea to the...

Ecological traits and range size determine the occurrence of non-native fish species in a Neotropical floodplain
In this study, we assessed the invasion process of non-native fish species in the upper Paraná River floodplain using survey data from 1986 to 2018....

A novel ZZ/ZW chromosome morphology type in Eigenmannia virescens (Gymnotiformes: Sternopygidae) from upper Paraná River basin
Gymnotiformes fishes present a great variation in chromosome numbers. Sternopygidae species are either sex-homomorphic or sex-heteromorphic. This...

Complete mitochondrial genomes and updated divergence time of the two freshwater clupeids endemic to Lake Tanganyika (Africa) suggest intralacustrine speciation
BackgroundThe hydrogeological history of Lake Tanganyika paints a complex image of several colonization and adaptive radiation events. The initial...

Repetitive DNAs and chromosome evolution in Megaleporinus obtusidens and M. reinhardti (Characiformes: Anostomidae)
The high dynamism of repetitive DNAs is a major driver of chromosome evolution. In particular, the accumulation of repetitive DNA sequences has been...

Differential MC5R loss in whales and manatees reveals convergent evolution to the marine environment
Melanocortin 5 receptor ( MC5R ), which is expressed in the terminally differentiated sebaceous gland, is a G protein-coupled receptor (GPCR). MC5R ...

Non-native fishes in Brazilian freshwaters: identifying biases and gaps in ecological research
Brazil is the country in the world with the highest freshwater fish diversity. Because of the high rates of species introduction, the number of...
