Effects of anthropic actions and forest areas on a neotropical aquatic ecosystem.

This research aimed to understand how anthropic impacts generated by sugarcane plantations and urban development affect a Neotropical river in northeastern Brazil, through the evaluation of the relationships between the local ichthyofauna and environmental variables, and different patterns of land cover, in addition to seasonal variation. Monthly samples of environmental parameters and icthyofauna were taken from September 2013 to August 2014 in the lower course of the Capibaribe River (PE, Brazil). Environmental parameters varied significantly among land cover and seasons, grouping separately samples from the Anthropized and Forested areas.

Ichthyofauna used in traditional medicine in Brazil.

Fish represent the group of vertebrates with the largest number of species and the largest geographic distribution; they are also used in different ways by modern civilizations. The goal of this study was to compile the current knowledge on the use of ichthyofauna in zootherapeutic practices in Brazil, including ecological and conservational commentary on the species recorded. We recorded a total of 85 species (44 fresh-water species and 41 salt-water species) used for medicinal purposes in Brazil.
