All Theses
Diplectrona modesta Banks 1908 (Trichoptera: Hydropsychidae) is a common inhabitant of streams across eastern North America. This species is well known and used often in biomonitoring studies. Experts in the field have long noted the morphological variation in larval head color and patterns as well as the species presence in many different types of habitats, such as springs, seeps, streams, and some small rivers. This study examines the species both morphologically and molecularly using mitochondrial and nuclear genes in order to determine if the species is a complex of several species or one highly variable species. DNA sequencing using the …

Oysters (Ostreidae) manifest a high degree of phenotypic plasticity, whereby morphology is of limited value for species identification and taxonomy. By using molecular data, the aim was to genetically characterize the species of Crassostrea occurring along the Brazilian coast, and phylogenetically relate these to other Crassostrea from different parts of the world. Sequencing of the partial cytochrome oxidase c subunit I gene (COI), revealed a total of three species of Crassostrea at 16 locations along the Brazilian coast. C. gasar was found from Curuca (Para state) to Santos (Sao Paulo state), and C. rhizophorae from Fortim (Ceara state) to Florianopolis …
