AFLPs (and to a lesser extent ISSRs and RAPDs) are increasingly being used for phylogenetic inference among closely related species. Presence/absence characters for each AFLP allele treat all absences as homologous to one another. With three or more alleles, terminals are grouped by their shared absence of alleles in character-based phylogenetic-inference methods in a manner that is not redunda...

<p>El metil mercurio (MeHg) es un contaminante ambiental tóxico y nocivo que se bioacumula biomagnifica en la cadena trófica. La tortuga Trachemys scripta elegans (Tse), considerada centinela de contaminación debido a su longevidad, posee eritrocitos (RBCs) nucleados con afinidad del 90% por MeHg. Este estudio determinó citotoxicidad genotoxicidad in vitro MeHg sobre RBCs Tse concentracio...
