Predation of eggs and embryos is one of the reasons of early mortality in anurans, and it is known that embryos of several amphibian species can accelerate its hatching, as a mechanism to reduce predation risk. Several ...

In the animal kingdom, behavioral traits encompass a broad spectrum of biological phenotypes that have critical roles in adaptive evolution, but an EvoDevo approach has not been broadly used to study behavior evolution. ...

Leeches exhibit a marked scope of diversity, including different kinds of symbiosis. The aim of the present study was to demonstrate through biochemical and histological analysis that a species of piscicolid leech, Myzobdella ...

The review proposes a comparison between recurrent inhibition in motor systems of vertebrates and the leech nervous system, where a detailed cellular and functional analysis has been accomplished. A comparative study shows ...

The occurrence of Helobdella triserialis associated with two freshwater snails, Pomacea diffusa and Pomacea canaliculata, is recorded for the first time in Brazil. We also point out the new association between the leech ...

The organization of the cytoskeleton in the early first interphase zygote and its involvement in organelle redistribution were studied in the glossiphoniid leech Theromyzon trizonare by confocal and electron microscopy, ...

Abstract Background Several Trypanosoma species transmitted by leeches infect marine and freshwater fish worldwide. To date, all South American fish trypanosome species ...
