Parasites with complex life-cycles and trophic transmission are expected to show low specificity towards final hosts. However, testing this hypothesis may be hampered by low taxonomic resolution, particularly in helminths. We investigated this issue using two intestinal fish parasites with similar life-cycles and occurring in sympatry, Pomphorhynch...

Loricariichthys platymetopon ocorria originalmente nos rios Uruguai, Paraguai e baixo Paraná. Com a formação do reservatório de Itaipu em 1982, invadiu e colonizou o alto rio Paraná. Usando os dados obtidos trimestralmente em nove pontos de amostragem na planície de inundação do alto rio Paraná, foram caracterizadas as fases reprodutivas e células ...
Male reproductive development is intricately dependent on fetal androgen action. Consequently, disrupted androgen action during fetal life can interfere with the development of the reproductive system resulting in adverse effects on reproductive function later in life. One biomarker used to evaluate fetal androgen action is the anogenital distance ...
This study focused on the study of earthworm survival, growth, reproduction, enzyme activities, and protein contents to evaluate and predict the effects of different soil pH levels and determine the optimal risk assessment indicators for the effects. Survival rate, growth rate, and cocoon number as well as four enzyme (glutathione peroxidase (GSH-P...
