Fishing Into the MicroRNA Transcriptome

Frontiers in Genetics, 2018
In the last decade, several studies have been focused on revealing the microRNA (miRNA) repertoire and determining their functions in farm animals such as poultry, pigs, cattle, and fish.

Genomic selection signatures in farmed Colossoma macropomum from tropical and subtropical regions in South America

Evolutionary Applications, 2022
Tambaqui or cachama (Colossoma macropomum) is one of the most important neotropical freshwater fish used for aquaculture in South America, and its production is concentrated at low latitudes (close to the Equator, 0°), where the water temperature is warm.

Genomic Differences Between the Sexes in a Fish Species Seen Through Satellite DNAs

Frontiers in Genetics, 2021
Neotropical fishes have highly diversified karyotypic and genomic characteristics and present many diverse sex chromosome systems, with various degrees of sex chromosome differentiation. Knowledge on their sex-specific composition and evolution, however,

Time-calibrated phylogeny of neotropical freshwater fishes

Frontiers in Bioinformatics
Neotropical Freshwater Fish (NFF) fauna exhibits the greatest phenotypic disparity and species richness among all continental aquatic vertebrate faunas, with more than 6,345 species distributed across the mostly tropical regions of Central and South America.

Subsistence harvest for food and pets associated with declining global mammal populations

Frontiers in Ecology and the Environment, EarlyView.
Subsistence harvest can have substantial impacts on mammalian biodiversity, yet its effects on the conservation status of mammal species are poorly understood. We analyzed trade and use data in species accounts from the International Union for Conservation of Nature (IUCN) Red List to examine the effects of subsistence harvest on the conservation ...

Comparative Cytogenetics Analysis Among Peckoltia Species (Siluriformes, Loricariidae): Insights on Karyotype Evolution and Biogeography in the Amazon Region

Frontiers in Genetics, 2021
Peckoltia is widely distributed genus in the Amazon and Orinoco basins and the Guiana Shield, containing 18 valid species, and distinct morphotypes still needing description in the scientific literature due to its great taxonomic complexity.

Linking regional and global functional trait data: insights from mammal communities in a fragmented Atlantic Forest landscape

Oikos, EarlyView.
Accurate functional trait data are essential for understanding ecosystem services and processes in fragmented landscapes. We evaluated whether the global EltonTraits 1.0 database adequately represents the functional structure of mammal communities in forest fragments and restoration sites in a highly fragmented Atlantic Forest landscape.

Reynolds shear-stress and velocity: positive biological response of neotropical fishes to hydraulic parameters in a vertical slot fishway

Neotropical Ichthyology
The barriers created by dams can cause negative impacts to aquatic communities, and migratory fish species are directly affected. Fishways have been developed to allow the upstream passage of fishes through dams.
