Area of Taxonomic Interest: Mollusca
Country: United States
Gary Rosenberg's research centers on the magnitude and origin of species-level diversity in the Mollusca. Estimates of the total number of living mollusc species range from less than 100,000 to more than 200,000 but there is little agreement even as to how many species of molluscs have already been discovered.
He uses electronic databases to better document the known diversity of molluscs and to estimate their total diversity. One such database is Malacolog 3., which gives distributions and synonyms for more than 4500 for Western Atlantic marine gastropods. Another is a 'Biotic Database of Indo-Pacific Marine Mollusks', collaborative effort across several institutions that treats about 25,000 species.
He also does research in Jamaica, which has one of the most diverse faunas of terrestrial mollusks in the world, with more than 550 species, about 90% of which are endemic. An interactive key to Jamaican land snail species is online at http://clade.ansp.org/malacology/collections/jamaica/index.html.
