Some trials suggested that flies kept outdoors lived just as long when they ate extra food as their hungrier outdoor counterparts—contrary to what tends to happen in the lab.
一些试验表明，当养在户外的苍蝇补充摄入食物时，其寿命与忍受饥饿的户外同类苍蝇的一样长——这与实验室中通常表现出的情况相反。

Around 65 per cent of Antarctic animals and plants could decline by the end of the century if conservation efforts aren’tratchetedup. Species expected to undergo the steepest population drops are emperor penguins, Adélie penguins, chinstrap penguins and soilnematodes.
如果保护工作不加紧进行，到本世纪末，约65%的南极动植物的数量可能会减少。预计数量减少最严重的物种将是帝企鹅、阿德利企鹅、帽带企鹅和旱地线虫等。
In a two-part analysis, Jasmine Lee at the British Antarctic Survey and her colleagues compiled scientific data topinpointwhich of the Antarctic’s wildlife will be most at risk under moderate and severe warming scenarios. Then, they asked a group of 29 international experts on Antarctic biodiversity to assess the cost and effectiveness of different management strategies over the next century, like reducing tourism and the spread of invasive species.
英国南极考察处的贾丝明·李和她的同事们在一项分两部分开展的分析中，汇集了科学数据，确定在中度以及极端气候变暖情况下，面临风险最大的南极野生动植物品种。翻译划线句，长按文末小程序码打卡，答案下期公布~
Under current management strategies and moderate warming, the team found 65 per cent of land plants and animals will decline by the end of the century. If warming is limited to below 2°C by 2100, the estimate drops to 31 per cent. “Everyone tends to think of Antarctica as this remote and untouched wilderness that’s free of these threats that are facing the rest of the world,” says Lee, but the results suggest otherwise.
研究小组发现，在当前管理策略和气候中度变暖的情况下，到本世纪末，65%的南极陆地动植物的数量将会出现下降。如果2100年以前把变暖幅度控制在2℃以内，估计这一比例会降至31%。李说，“每个人都往往认为南极洲距离遥远，是不会受到影响的荒野之地，可以免受世界其它地区面临的威胁”，但研究结果表明并非如此。
Seabirds wereslatedto endure the steepest declines, with emperor penguins (Aptenodytes forsteri) losing 90 per cent of their population by 2100, largely because they rely on ice for breeding. Dry soil nematodes and Adélie penguins (Pygoscelis adeliae) are expected to decline by more than half. Not all species suffered from climate change: some native flowering plants are expected to spread with warmer temperatures and more available liquid water.
海鸟数量预计将出现最严重的下降，到2100年，帝企鹅的数量将会减少90%，主要是因为它们依赖冰来繁殖。旱地线虫和阿德利企鹅的数量预计将减少一半以上。并非所有的物种都会受到气候变化的影响：一些本土花卉植物预计会随着温度升高、可用液态水增加而繁衍壮大。
Finally, the 29 experts collectively identified 10 key steps to reduce the most severe damage at an annual cost of $23 million – excluding the cost of addressing climate change – that could benefit up to 84 per cent of plants and animals. The most promising solutions were increasing habitat protection for vulnerable species, managing the spread of disease and reducing the introduction of invasive species.
最后，29位专家共同确定了10个关键步骤以此来减少给南极带来的最严重的破坏，每年花费的成本为2300万美元（这其中不包括应对气候变化的成本），可使高达84%的动植物受益。最有希望的解决方案是加强对脆弱物种的栖息地保护，控制疾病的传播，减少入侵物种的引入。
