Census of Private Mammal Collections

A census of mammal populations in Punta Leona Private Wildlife Refuge, Costa Rica.

Population sizes of six mammal species were estimated using the King method during the late dry season (March) of 1996 in the Punta Leona Private Wildlife Refuge, Costa Rica. The white-faced monkey (Cebus capucinus), coati (Nasua narica) and nine-banded armadillo (Dasypus novemcinctus) with 148, 46, and 8 sighted individuals, respectively, demonstrated the largest populations in the refuge. The...

Marine Mammal Census Using Space Satellite Imagery

A new era of commercial high-resolution imagery from space began late in 1999 resulting in resolution that is now sufficient to resolve marine mammals. This encouraged investigating the use of satellite imagery for marine-mammal population census and related studies. The question was raised: Can marine mammals be reliably detected above sensor noise and ocean clutter? To answer this question, a...

Taxonomic resolution of sawfish rostra from two private collections

Management and recovery of endangered sawfishes are challenged by the un certainty of species determination. Frequently, dried rostra (saws) are the only material available to represent an historical occurrence, yet traditional methods of species identification of datadeficient rostra (rostral tooth counts) are unreliable. We evaluated the utility of morphometric characters for the identificati...
