科学家们研究斯瓦尔巴德的北极熊如何适应冰融化,但未来仍不确定。 Scientists study adapting polar bears in Svalbard as ice melts, but future remains uncertain.

挪威极地研究所40年来一直在研究斯瓦尔巴德群岛的北极熊,调整了跟踪全球迅速升温影响的方法。 The Norwegian Polar Institute has been studying polar bears in the Svalbard archipelago for four decades, adapting methods to track the impacts of rapid global warming. 今年,科学家们正在使用新的技术,包括监测熊体内的“永远的化学物质”。 This year, scientists are using new techniques, including monitoring "forever chemicals" in the bears' bodies. 他们观察到北极熊的饮食正在改变 包括更多的陆地食物 因为冰融化, 但仍比预期的更好适应。 They observe that polar bears are changing their diet to include more land-based foods due to melting ice, but are still adapting better than expected. 尽管如此,未来仍不确定,因为进一步的冰块流失可能影响到它们捕猎海豹的能力,而海豹是它们的主要食物来源。 Despite this, the future is uncertain as further ice loss could affect their ability to hunt seals, their primary food source.
