Deceptive desmas: molecular phylogenetics suggests a new classification and uncovers convergent evolution of lithistid demosponges.

Tendo em conta os aspetos destacados ao longo do enquadramento teórico apresentado anteriormente, foram definidos dois grandes objetivos para o presente estudo: (1) testar

Laboratory-adapted strains of the closely related parasites Sarcocystis falcatula and Sarcocystis neurona were investigated, along with Neospora caninum , Neospora hughesi ,

Thus, this study aimed to evaluate the trade of juvenile catfish between seed suppliers and fish farmers in Brazil using molecular markers (four nuclear loci and 1

In that sense, models of molecular signatures representing directional selection or neutral evolution were tested in the HoxA13 of snakes, amphisbaenians and caecilians using

The present analysis was based on a robust genetic tool consisting of the sequences of a fragment of mitochondrial DNA (used to identify the maternal lineage) and multiplex PCR of a

This study has four aims: (1) to propose a robust hypothesis of phylogenetic relationships for the tribe based on the analysis of all genera and 80% of the valid species in
