In research presented lately at a meeting of the British Ecological Society in Liverpool, scientists will explain how rising temperatures are depriving female reindeer of nutrients during important phases of gestation.
日前,科学家们在利物浦英国生态学会的会议上展示了这项研究成果,他们将解释在雌性驯鹿怀孕的关键阶段,气温升高是如何令其失去营养的。
Snow in Svalbard typically covers the ground for eight months of the year, which, combined with low temperatures, limits grass growth to June and July.
通常,斯瓦尔巴德岛一年中有八个月都被白雪覆盖,而且气温极低,小草的生长期仅限于六月和七月。
But as summer temperatures have increased by around 1.5℃, pastures have become more productive, allowing female reindeer to gain more weight by the autumn and therefore to conceive more calves.
但由于夏季气温升高了约1.5℃,牧草地变得更茂盛,这使得雌性驯鹿到了秋天会变胖且能孕育更多小鹿。
However, warmer winters have brought with them greater rainfall which freezes when it settles on the snow, thereby locking out the reindeer from the life-sustaining food below.
然而,温暖的冬天带来了更多的降雨,雨水落在雪地里会结冰,阻止驯鹿获得冰面下维持生命的食物。
As a result, female reindeer are becoming starved, causing them to abort their calves or giving birth to much lighter young.
