The neotropical bee Centris nitida Smith has naturalized in southeastern Florida and in Sarasota on the Gulf coast. This furry yellow and black bee has been confused with the closely related C. lanosa Cresson, a native bee restricted to northern Florida and the American Southwest and adjacent Mexico. Female C. nitida are smaller than those of both C. lanosa and C. errans Fox, a furry brown-colo...

As a resource for vertebrate phylogenetics, we developed 75 new protein-coding genes using a combination of expressed sequence tags (ESTs) available in Genbank, and targeted amplification of complementary DNA (cDNA). In addition, we performed three additional analyses in order to assess the utility of our approach. First, we profiled the phylogenetic informativeness of these new markers using t...

Although the phenomenon of sexual dimorphism is widespread in vertebrates, the molecular mechanism of sex-determination is not the same across animal phyla, in contrast to other areas of developmental biology. Recent extensive studies, however, have given proof of evolutionarily conserved function in genes which share a novel DNA binding DM domain, primarily identified in two invertebrate sex r...

The recent segregation of 12 genera in the tribe Streblocladieae suggests that taxonomy some species belonging to Polysiphonia sensu lato is updated with transfer and proposal new combinations. Accordingly, six additions on basis morphological molecular analyses are presented as a consequence this segregation. These include description Carradoriella platensis sp. nov., following combinations Eu...
