Land Bridges and Ecology in Bat Distribution on Islands off the Northern Coast of South America

Bats of the Antillean Island of Grenada : a new zoogeographic perspective /

“…The species is abundant and widespread on Trinidad, Tobago, and Little Tobago (Goodwin and Greenhall, 1961). Seba's shorttailed bat would appear to be successfu1 in habitats d~s-tubed by human or weather activities; therefore, the appropriate habitats would appear to be available on Remarks.-The lesser gray fmt-eating bat has been reported previously from Grenada based upon a single speclmen from Grand 6tang (Koopman, 1958). This female bat was captured in November 19 12.…”

“…The specimen from Vendbme was taken in another habitat type at an elevation of about 300 m. Nets were set over a small stream as it emerged from Grand tan^ Forest Reserve. The Remarks.-Because the Brazilian large-eared bat is represented from Grenada by a single, long-preserved museum specimen, we have questioned, as h d Koopman (1958), whether it represented an existing population or a slngIe accidental record. However, with report of a population of this species on St. Vincent by Vaughan (1 995) and Vaughan and Hill (1997), it seems possible that our specimen could represent a Grenadan population.…”

The value of georeferenced collection records for predicting patterns of mosquito species richness and endemism in the Neotropics

“…The species richness of Trinidad-Tobago has also been shown for bats and passerine birds (Koopman, 1958). These islands are considered continental, and would have been joined to the mainland during the Pleistocene (Koopman, 1958). Only 33 species, however, are common between Trinidad-Tobago and Venezuela (the closest continental area), including five of seven Wyeomyia, three of eight Anopheles, six of 13 Culex, and five of seven Aedes.…”

Patterns of Species Co-occurrence in the Antillean Bat Fauna

“…In the first approach, plots of column totals (island species-richnesses) against island area and other physiographic parameters have been analysed statistically with linear and multiple regression models to investigate what has been called the species-richness/island area relationship (MacArthur and Wilson 1967 ;Connor and McCoy 1979). An earlier analysis of West Indian bats in a similar vein was undertaken by Koopman (1958), but without statistical treatment. Recently, Mammalia, t. 53, n° 1, 1989.
