Amazing how what SHOULD have been just a good paper on Wildlife Management and Ecology HAS TO BE about Global Warming..
Articles like this one --- tho good science --- make me suspicious that we are using GW as an EXCUSE to general scientific work.. And that leads to corrupted works and conclusions..
The average weight of adult reindeer on Svalbard, a chain of islands north of Norway, has fallen to 48kg from 55kg in the 1990s as part of sweeping changes to Arctic life as temperatures rise, they said. “Warmer summers are great for reindeer but winters are getting increasingly tough,” said Steve Albon, an ecologist at the James Hutton Institute in Scotland who led the study with Norwegian researchers.
Less chilly winters mean that once-reliable snows fall more often as rain that can freeze into a sheet of ice, making it harder for the herbivores to reach plant food. Some reindeer starve and females often give birth to stunted young. In summer plants flourish in a food bonanza that ensures healthy females more likely to conceive in autumn — a pregnancy lasts about seven months. The wild herd studied had expanded to about 1,400 animals from 800 since the 1990s. “So far we have more, but smaller reindeer,” Albon said of reindeer on Svalbard, about 1,300km from the North Pole.

The rising population also means more competition for scarce food in winter. Arctic temperatures are rising faster than the world average amid a build-up of greenhouse gases in the atmosphere. Most studies of global warming around Svalbard have focused on polar bears that hunt seals at sea, rather than year-round land residents led by reindeer, Arctic foxes and Svalbard rock ptarmigan birds.
Arctic fox numbers have risen slightly because they thrive in severe ice winters by scavenging dead reindeer, said Eva Fuglei, a researcher at the Norwegian Polar Institute and the Fram Centre who was not involved in the reindeer study. “All the weak reindeer die — the sick, the elderly and calves,” she said. However, that means foxes struggle to feed the next winter because only the fittest adult reindeer have survived.
