Seasonal Climate Variation and Caribou Availability: Modeling Sequential Movement Using Satellite-Relocation Data
Livelihood systems that depend on mobile resources must constantly adapt to change. For people living in permanent settlements, environmental changes that affect the distribution of a migratory species may reduce the availability of a primary food source, with the potential to destabilize the regional social-ecological system. Food security for Arctic indigenous peoples harvesting barren ground...
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 کاملUnveiling trade-offs in resource selection of migratory caribou using a mechanistic movement model of availability
animals move in response to a variety of competing pressures such as the need to feed, avoid predators, breed, and rear offspring (Brown et al. 1999, Cresswell 2008). These competing demands give rise to trade-offs that individuals must mediate through their space use and movements (Lima 1998, Hebblewhite and Merrill 2009), resulting in distinctive patterns of habitat selection. Numerous studie...
متن کاملContagious Yawning and Seasonal Climate Variation
Recent evidence suggests that yawning is a thermoregulatory behavior. To explore this possibility further, the frequency of contagious yawning in humans was measured while outdoors in a desert climate in the United States during two distinct temperature ranges and seasons (winter: 22°C; early summer: 37°C). As predicted, the proportion of pedestrians who yawned in response to seeing pictures of...
متن کاملFirst satellite tracks of South Atlantic sea turtle ‘lost years’: seasonal variation in trans-equatorial movement
In the South Atlantic Ocean, few data exist regarding the dispersal of young oceanic sea turtles. We characterized the movements of laboratory-reared yearling loggerhead turtles from Brazilian rookeries using novel telemetry techniques, testing for differences in dispersal during different periods of the sea turtle hatching season that correspond to seasonal changes in ocean currents. Oceanogra...
