Inferring the evolutionary and biogeographic history of taxa occurring in a particular region is one way to determine the processes by which the biodiversity of that region originated. Tree boas of the genus Corallus are an ancient clade and occur throughout Central and South America and the Lesser Antilles, making it an excellent group for investigating Neotropical biogeography. Using sequence...
There are almost 1,700 species of mammals occurring in the Neotropical region broadly defined as including Mexico, Central America, the Caribbean Islands, and South America. The Barcode of Life Data (BOLD) Systems established an institutional collaboration with the Royal Ontario Museum (ROM) beginning in 2005 to DNA barcode the mammal tissue collections for the cytochrome oxidase subunit I (COI...
We present a DNA barcoding study of Neotropical odonates from the Upper Plata basin, Brazil. A total of 38 species were collected in a transition region of "Cerrado" and Atlantic Forest, both regarded as biological hotspots, and 130 cytochrome c oxidase subunit I (COI) barcodes were generated for the collected specimens. The distinct gap between intraspecific (0-2%) and interspecific variation ...
Water mite species of the genus Hydrodroma Koch, 1837 are common in running and standing waters Neotropical region. In this study four reported from Argentina. Redefinitions given for H. peregrina (Koenike, 1905), robusta K. Viets, 1954 stat. nov., longiseta 1954, nov. Two species, i.e., argentinensis sp. ventana described as new science.
Corbicula fluminea is an aggressive invasive species of bivalve that arrived into the Río de la Plata River between the late 60's and early 70's, and dispersed widely throughout the Neotropical region, evidencing a great adaptive flexibility to different environmental conditions. This species is a functional hermaphrodite with larval incubation inside the inner demibranch. Despite its widesprea...
Interest in studying galls and their arthropods inducers has been growing rapidly in the last two decades. However, the Neotropical region is probably the least studied region for gall-inducing arthropods. A study of the richness and composition of gall-inducing arthropods was carried out at Coiba National Park in the Republic of Panama. Field data come from samples obtained between August 1997...
