Ecology of the Porcupine caribou herd
Researchers have described general patterns of population regulation that fit most caribou (Rangifer tarandus) herds. Nevertheless, specific factors operating on particular populations vary greatly, and efforts to categorize herds according to the general patterns often lead to confusion. It is difficult for biologists to attempt to describe population dynamics in terms of density relationships...
متن کاملParasite prevalence, infection intensity and richness in an endangered population, the Atlantic-Gaspésie caribou
The Atlantic-Gaspésie caribou (Rangifer tarandus caribou) population is a small isolated relict herd considered endangered according to the Canadian Species at Risk Act (SARA). This population has low recruitment and survival rates but the potential role of parasites on individual fitness is unknown. In this context, we explored the parasite status of this population with the aim of 1) assessin...
متن کاملSeasonal movements of satellite-collared caribou from the Bathurst herd
SUMMARY We tracked the movements of between six and 19 caribou cows from the Bathurst herd from April 1996 to December 2000 using collars that transmit to a satellite. Spring migration routes partially depended where the caribou wintered which changed from northwest of Great Slave Lake to southeast of Great Slave Lake in winter 1997/98 and 2000/01. In winters of 1998/99 and1999/2000, distributi...
متن کاملTesting the Goodness of Supplementary Feeding to Enhance Population Viability in an Endangered Vulture
BACKGROUND Human-predator conflicts are directly or indirectly threatening many species with extinction. Thus, biologists are urged to find simple solutions to complex situations while avoiding unforeseen conservation outcomes. The provision of supplementary food at artificial feeding sites (AFS) is frequently used in the conservation of scavenger bird populations currently suffering from indir...
متن کاملPopulation-specific vital rate contributions influence management of an endangered ungulate.
To develop effective management strategies for the recovery of threatened and endangered species, it is critical to identify those vital rates (survival and reproductive parameters) responsible for poor population performance and those whose increase will most efficiently change a population's trajectory. In actual application, however, approaches identifying key vital rates are often limited b...
