Grizzly bears have stopped eating salmon in favour of elderberries after being forced to make a choice due to climate change. Warming temperatures meant that the berries are ripening earlier than usual, at exactly the same time as the freshwater streams on Alaska’s Kodiak Island are overflowing with sockeye salmon.

由于气候变化的影响，灰熊被迫做出艰难抉择，放弃鲑鱼改吃接骨木果。温暖的气候使得浆果成熟期提前，与此同时，阿拉斯加科迪亚克岛的淡水河流里也挤满了红鲑。

The island's brown bears typically feed first on salmon in early summer, followed by elderberries later in the season, in late August and September.

往年，岛上的棕熊在夏初先吃了鲑鱼，然后在八月末和九月吃接骨木果。

"What you have is a scrambling of the schedule," said William Deacy, a biologist at Oregon State University that studied the phenomenon.

研究这个现象的俄勒冈州立大学的生物学家威廉•迪西称：“如今的生物成熟期十分混乱。”

"It's essentially like if breakfast and lunch were served at same time and then there is nothing to eat until dinner.

“这就好比早餐和午餐同时送上来，那么晚餐前就什么都没得吃了。”

"You have to choose between breakfast and lunch because you can only eat so much at a time."

“你必须在早餐和午餐间做抉择，因为你一次只能吃那么多。”
