Ichthyofauna Used in Traditional Medicine in Brazil
Evidence-Based Complementary and Alternative Medicine, Volume 2012, Issue 1, 2012., 2012 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

Ecotoxicology and Environmental Safety, 2002 Tributyltin (TBT) is widely used as a biocide in antifouling paints. Astyanax bimaculatus adult fish were acclimatized in a laboratory and isolated in groups of eight individuals. Two groups were used as a control (similar handling and corn oil control) and one group was exposed to TBTCI dissolved in corn oil (0.0688 +/- 0.0031 microg TBT.g(-1)) every ...

Continuous tooth replacement: what can teleost fish teach us?
Biological Reviews, Volume 99, Issue 3, Page 797-819, June 2024.ABSTRACT Most tooth‐bearing non‐mammalian vertebrates have the capacity to replace their teeth throughout life. This capacity was lost in mammals, which replace their teeth only once at most. Not surprisingly, continuous tooth replacement has attracted much attention. Classical morphological studies (e.g.

International Journal of Zoology, Volume 2012, Issue 1, 2012., 2012 To date, little attention has been devoted to possible complementary effects of multiple forms of public information similar information on the foraging behaviour of predators. In order to examine how predators may incorporate multiple information sources, we conducted a series of predator attraction trials in the Lower Aripo River, Trinidad.

Assessing fish diversity in abandoned mining ponds in Madre de Dios, Peru, using environmental DNA
Environmental DNA, Volume 6, Issue 1, January–February 2024.We surveyed four lentic systems in Madre de Dios, Peru: two abandoned mining ponds created by ASGM and two unmined oxbow lakes as a reference to assess fish recolonization. We compared two alternative eDNA processing methods and contrasted our results with historic data from traditional biodiversity monitoring. Our results indicate that eDNA could be a
