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.

Efeito anestésico do óleo de cravo em alevinos de lambari Anesthetic effect of clove oil on lambari

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

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
