Dimensões lúdico-sagradas e resistências das congadas em Lambari (MG)

Revista Extraprensa, 2020
A Congada é uma tradicional festa popular brasileira criada por pessoas negras escravizadas como uma reedição dos cortejos reais africanos. Essa manifestação cultural modificou seus significados originais diante das necessidades de representação e de reatamento dos laços identitários de uma população sequestrada da sua terra natal e lançada ao trabalho

The effect of LHRHa with and without dopamine antagonist on reproductive performance in lambari Astyanax altiparanae

Aquaculture, 2022
The present study evaluated the effect of luteinizing hormone-releasing hormone analogue (LHRHa) with and without dopamine antagonist (i.e., domperidone (D)) on the reproductive performance of lambari females (Astyanax altiparanae) as well as on secretion of 17α-20β-dihydroxy-4-pregnen-3-one (17,20β-P) and prostaglandin F2α (PGF2α)) and on the ...

Efeito anestésico do óleo de cravo em alevinos de lambari [PDF]

Ciência Rural, 2009
Para avaliar o efeito anestésico do óleo de cravo em lambaris (Astyanax altiparanae), cinco grupos de 30 alevinos (0,6±0,1g) foram expostos às concentrações de 50, 75, 100, 125 e 150mg L-1, medindo-se, respectivamente: tempo de indução à anestesia profunda (caracterizada pela perda de equilíbrio, pela ausência de natação, pela redução dos movimentos ...

Eco-evolutionary factors that influence its demographic oscillations in Prochilodus costatus (Actinopterygii: Characiformes) populations evidenced through a genetic spatial-temporal evaluation. [PDF]

Evol Appl, 2023
Abstract The human activity impact on wild animal populations is indicated by eco‐evolutionary and demographic processes, along with their survival and capacity to evolve; consequently, such data can contribute toward enhancing genetic‐based conservation programs.

Genetic evaluation of migratory fish: Implications for conservation and stocking programs. [PDF]

Ecol Evol, 2020
We investigated the genetic diversity, population structure, and gene flow (migration) of the Neotropical migratory fish Prochilodus costatus in the Três Marias dam in São Francisco River basin, Brazil. The samples showed low genetic variability, with inbreeding and the presence of only four genetic pools.

Antioxidant Defenses in the Kidneys and Heart of the Freshwater Fish Astyanax lacustris Subjected to High (31°C) and Low (15°C) Temperatures. [PDF]

Cell Biochem Funct
ABSTRACT Aquatic ecosystems have their abiotic and biotic factors constantly altered by various factors. Among them, water temperature is an abiotic factor that can significantly affect fish physiology, increasing energy demand, which can impact homeostasis and survival. Endocrine and metabolic changes and enzymatic modulation are referred to as stress

Distribution modelling for Neotropical freshwater stingrays Potamotrygon brachyura and Potamotrygon motoro (Myliobatiformes, Potamotrygonidae) in the Uruguay River basin. [PDF]

J Fish Biol
Abstract This study aimed to identify geographical distribution patterns of the giant short‐tailed river stingray Potamotrygon brachyura and the motoro stingray Potamotrygon motoro in the Uruguay River basin. Data on presence/absence of stingrays were based on fishers' knowledge accessed by interviews through expeditions in Brazil, Argentina and ...
