Large-scale climate oscillations may contribute to the observed dramatic fluctuations and regional synchrony in Rangifer abundance. Here, we test this hypothesis using long-term abundance and physical condition datasets to investigate the relationships between broad climate patterns, summer-range quality, and population dynamics in three barren-ground caribou herds in northern Canada. We found that positive intensities of the Arctic Oscillation (AO) in the summer were associated with warmer… Expand

Spatial heterogeneity in climate change effects decouples the long‐term dynamics of wild reindeer populations in the high Arctic
It is shown that spatially autocorrelated fluctuations in annual winter weather synchronize wild reindeer dynamics across high‐Arctic Svalbard, while, paradoxically, spatial variation in winter climate trends contribute to diverging local population trajectories. Expand
Population dynamics under climate change ad harvesting: Results from the high Arctic Svalbard reindeer
Arctic winters have become increasingly warmer and rainier.Where permafrost prevails, winter rain (or rain-on-snow) is known to occasionally cause extensive ice layers at the snow/ground interface,Expand

Linkages between large-scale climate patterns and the dynamics of Arctic caribou populations
Recent research has linked climate warming to global declines in caribou and reindeer (both Rangifer tarandus) populations. We hypothesize large-scale climate patterns are a contributing factorExpand
Long-term responses in arctic ungulate dynamics to changes in climatic and trophic processes
How different winter climate regimes and density-dependent processes during the past century have affected population dynamics of two arctic ungulate species is explored on a recently developed plant–herbivore–climate model. Expand
Arctic greening from warming promotes declines in caribou populations
It is demonstrated that the sea ice cover in the Arctic Ocean has provided a strong signal for climate-induced changes on the adjacent caribou summer ranges, outperforming other climate indices in explaining the caribous-plant dynamics. Expand
Observed and predicted effects of climate change on Arctic caribou and reindeer
The ability of many species to adapt to the shifting environmental conditions associated with climate change will be a key determinant of their persistence in the coming decades. This is a challengeExpand
Experimental warming alters migratory caribou forage quality.
The demonstration of the potential for significant warming impacts on forage quality at critical times for these animals underscores the importance of effective Rangifer range conservation to ensure sufficient appropriate habitat to support adaptability in forage selection in a rapidly changing environment.

Study of changes in the abundance, vital rates, body size, and timing of migration of the Buchans Plateau caribou herd in Newfoundland, Canada found that Spring migration was significantly later and autumn migration significantly earlier, and it is surmise that these responses may reflect heightened density-dependent competition for summer forage.

Voles, lemmings and caribou - population cycles revisited?
Caribou responses to decadal trends in climate likely accumulate through successive cohorts as changes in body mass which, in turn, leads to changes in lifetime reproductive success. Expand
Evolving perspectives on caribou population dynamics, have we got it right yet?
A review of the mortality of young calves documented in the past 30 years provides no support for the hypothesis that hypothermia is a common mortality problem and is hypothesized that the most important ecological variable in all seasonal distributions of caribou is predation risk rather than to maximize forage supplies.

Limiting factors in caribou population ecology
A diversity of limiting factors affecting caribou and wild reindeer populations is a reflection of the ecologial complexity of the species, a concept that has often been ignored in past efforts to reach management decisions by extrapolation from the limited localized knowledge available on the species.

Synchronization of animal population dynamics by large-scale climate
It is reported that the dynamics of caribou and musk oxen on opposite coasts of Greenland show spatial synchrony among populations of both species that correlates with the NAO index, indicating that animal populations of different species may respond synchronously to global climate change over large regions.
