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 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 کاملVariations in plant forage quality in the range of the Porcupine caribou herd 1
Understanding potential impacts of vegetation change on caribou energetics requires information on varia¬ tions in forage quality among different plant types and over time. We synthesized data on forage quality (nitrogen, neutral detergent fiber and dry matter digestibility) for 10 plant growth forms from existing scientific literature and from field research in the Arctic National Wildlife Ref...
متن کاملModeling Caribou Movements: Seasonal Ranges and Migration Routes of the Central Arctic Herd
Migration is an important component of the life history of many animals, but persistence of large-scale terrestrial migrations is being challenged by environmental changes that fragment habitats and create obstacles to animal movements. In northern Alaska, the Central Arctic herd (CAH) of barren-ground caribou (Rangifer tarandus granti) is known to migrate over large distances, but the herd's s...
متن کاملSmallholder Dairy Herd Management in Kenya

The main breeds for dairy production are Friesian, Guernsey, Ayrshire and their crosses with the local East African Zebu (EAZ). The EAZ population is estimated at about 10 mil...
