Population genetic structure and dispersal in white-lipped peccaries (Tayassu pecari) from the Brazilian Pantanal
(Alliance Communications Group Division Allen Press, 2011-04-15)
In many mammals social organization promotes genetic structuring, which can be influenced by the dispersal pattern of the species. We analyzed the population genetic structure and dispersal of white-lipped peccaries (Tayassu ...
The amphibian tree of life
(Amer Museum Natural History, 2006-01-01)
The evidentiary basis of the currently accepted classification of living amphibians is discussed and shown not to warrant the degree of authority conferred on it by use and tradition. A new taxonomy of living amphibians ...

Molecular identification of trypanosomatids in wild animals
(Elsevier B.V., 2014-06-16)
Diverse wild animal species can be reservoirs of zoonotic flagellate parasites, which can cause pathologic Chagas disease. The present study aimed to detect the natural occurrence of flagellate parasites through direct ...
Improved solution for vitrification of Prochilodus lineatus embryos based on the reduction in risk factors: Toxicity, osmotic responses and ice-nucleation
(Wiley-Blackwell, 2018-02-01)
The objective of our work was to describe a low toxicity cryoprotectant solution that allowed vitreous solid formation. Embryos of Prochilodus lineatus were submitted to sensitivity evaluations of six internal cryoprotectants ...
Morphological evaluation of Prochilodus lineatus embryos after vitrification-thawing in high-osmolarity cryoprotectant solution
(Wiley-Blackwell, 2018-12-01)
We aimed to vitrify embryos of Prochilodus lineatus in a high-osmolarity cryoprotectant solution, evaluating, after the vitrification-thawing process, their morphological changes. Thus, 240 embryos in the 20-somite phase ...
Growth, fatty acid composition, and reproductive parameters of diploid and triploid yellowtail tetra Astyanax altiparanae
(Elsevier B.V., 2017-03-20)
The aim of this study was to evaluate the growth, carcass yield, fatty acid composition, and reproductive parameters of diploid and triploid Astyanax altiparanae. Triploidization was induced by heat shock (40 degrees C for ...
Capturing, induced spawning, and first feeding of wild-caught Pseudopimelodus mangurus, an endangered catfish species
(Univ Catolica De Valparaiso, 2020-01-01)
This study aimed to describe a procedure for sampling, reproduction, and first feeding of the Neotropical catfish Pseudopimelodus mangurus, an endangered fish species. Wild adult P. mangurus specimens were collected in the ...
The first case of induced gynogenesis in Neotropical fishes using the yellowtail tetra (Astyanax altiparanae) as a model organism
(Elsevier B.V., 2020-01-01)
Gynogenesis is a chromosome manipulation technique applicable on the production of all-female populations, generation of inbred or clonal lines and identification of genetic sex determination mechanisms in fish. Therefore, ...
Staphylococcus sciurias a Reservoir ofmecA toStaphylococcus aureusin Non-Migratory Seabirds from a Remote Oceanic Island
(Mary Ann Liebert, Inc, 2020-08-18)
Aim:Genomic analysis of a methicillin-resistantStaphylococcus aureus(MRSA) strain cultured from a non-migratory seabird at Fernando de Noronha Archipelago (Brazilian oceanic islands) was carried out to investigate the ...
