Recognition Of Two New Species Of Freshwater Crabs From The Seychelles Based On Molecular Evidence (Potamoidea: Potamonautidae)., Neil Cumberlidge, Savel Regan Daniels Phd

Journal Articles

The Afrotropical freshwater crab genus Seychellum is endemic to the granitic Seychelles in the Indian Ocean (Mahé, Silhouette, Praslin, La Digue and Frégate). Here we describe two new cryptic species of Seychellum that represent two evolutionarily separate lineages of a previously monotypic genus. This raises to three the number of species of freshwater crabs known from Seychelles. Each species is endemic to either one island (Silhouette) or to a pair of islands (Mahé and Frégate, or Praslin and La Digue). The three species can be clearly distinguished as separate lineages by DNA analysis, haplotyping and examination of gonopod characters. The …

It's Not Too Late For The Harpy Eagle (Harpia Harpyja): High Levels Of Genetic Diversity And Differentiation Can Fuel Conservation Programs, Heather R. Lerner, Jeff A. Johnson, Alec R. Lindsay Ph. D., Lloyd F. Kiff, David P. Mindell

Background: The harpy eagle (Harpia harpyja) is the largest Neotropical bird of prey and is threatened by human persecution and habitat loss and fragmentation. Current conservation strategies include local education, captive rearing and reintroduction, and protection or creation of trans-national habitat blocks and corridors. Baseline genetic data prior to reintroduction of captive-bred stock is essential for guiding such efforts but has not been gathered previously.

Methodology/Findings: We assessed levels of genetic diversity, population structure and demographic history for harpy eagles using samples collected throughout a large portion of their geographic distribution in Central America (n = 32) and South America …
