So this means that their thermal tolerance range narrows. And that we found for both species.

这意味着它们的热耐受性范围变窄了。我们发现这两个两种鳕鱼都是如此。

Even this desert-adapted bird has a thermal tolerance limit, and the sweltering Phoenix summer – exacerbated by the urban heat-island effect – often surpasses it.

即使是这种适应沙漠的鸟类也有耐热极限，而炎热的凤凰城夏季——由于城市热岛效应而加剧——常常超过它。
