Integrating multiple genetic detection methods to estimate population density of social and territorial carnivores
(Ecological Society of America, 2018-10)
Spatial capture-recapture models can produce unbiased estimates of population density, but sparse detection data often plague studies of social and territorial carnivores. Integrating multiple types of detection data can ...
An assessment of the niche centroid hypothesis: Pteropus lylei (Chiroptera)
Recent ecological theories propose that species reach their highest abundance and genetic diversity in the center of their ecological niche and decline toward the edges. We assessed whether Lyle's flying fox, Pteropus ...
Evaluating methods for estimating rare events with zero-heavy data: a simulation model estimating sea turtle bycatch in the pelagic longline fishery
(National Marine Fisheries Service Scientific Publication Office, 2012-07)
Estimating rare events from zero-heavy data (data with many zero values) is a common challenge in fisheries science and ecology. For example, loggerhead sea turtles (Caretta caretta) and leatherback sea turtles (Dermochelys ...
Ocelot Leopardus pardalis in Belize: the impact of trap spacing and distance moved on density estimates
(Cambridge University Press, 2007-10)
We used remote cameras to obtain information on an elusive species and to examine the effects of different camera trapping methodologies on abundance estimates. We determined activity pattern, trail use, trap success, and ...
A production modeling approach to the assessment of the horseshoe crab (Limulds polyphemus) population in Delaware Bay
(National Marine Fisheries Service Scientific Publication Office, 2006-04)
Horseshoe crab (Limulus polyphemus) is harvested commercially, used by the biomedical industry, and provides food for migrating shorebirds, particularly in Delaware Bay. Recently, decreasing crab population trends in this ...
