ABSTRACT Understanding the impact of human activities on fish communities is critical for the effective conservation of Amazonian ecosystems. In this study, we sampled environmental DNA (eDNA) from 17 sites (lakes and rivers) in two Peruvian national reserves, Pacaya‐Samiria and Allpahuayo‐Mishana, using a metabarcoding approach with four genetic ...

Transmission Behavior of B Chromosomes in Prochilodus lineatus (Characiformes, Prochilodontidae).
The population of Prochilodus lineatus found in the Mogi-Guaçu River is karyotypically polymorphic, carrying acrocentric, metacentric, and submetacentric B chromosomes. The analysis of each B chromosome frequency in this species revealed a variation in the distribution pattern, with the metacentric type having the highest frequency (73.30%), followed ...

Using eDNA metabarcoding, we assessed fish diversity in isolated sinkholes in southern Brazil, uncovering signs of local extinction and species persistence. This approach offers a non‐invasive tool for biodiversity assessment and informs conservation efforts in unique karst environments.

Neste trabalho foram avaliadas as alterações histopatológicas de fígados de juvenis de curimbatá, Prochilodus lineatus (Valenciennes, 1836) expostos a uma concentração de 0,2 µl/L do organofosforado Dipterex 500 (Trichlorfon).

Low‐Effort eDNA Sampling Reveals Fish Community Patterns in a Neotropical River Basin
Low eDNA sampling effort (< 10 sample sites) using a portable on‐site kit with syringe filters and a modest water volume (< 500 mL per site) provided a rapid and robust snapshot of fish biodiversity. Environmental DNA based species richness increases along the upstream‐downstream gradient showing a significant negative correlation with river elevation ...

Comet assay in gill cells of Prochilodus lineatus exposed in vivo to cypermethrin
Agricultural chemicals can induce genetic alterations on aquatic organisms that have been associated with effects on growth, reproduction and population dynamics. The evaluation of DNA damage in fish using the comet assay (CA) frequently involves the utilization of erythrocytes.

Thiacloprid (THI), widely used for crop protection and pest control, is easily residual and accumulated in the environment because of long half‐life and high leaching effect. The detectable rate of THI in soil and water is high, which can lead to the accumulation in organisms and cause toxic effects through sustained exposure to humans and nontargeted ...
