热带低地昆虫面临大规模死亡,因为气候变化迫使气温超出其耐热能力。 Tropical lowland insects face mass die-offs as climate change pushes temperatures beyond their heat tolerance.

一项新的研究显示,热带低地昆虫对生态系统至关重要,但适应气温上升的能力有限,亚马逊未来地表温度高达52%,有可能在半数研究的昆虫群中造成与热有关的死亡。 A new study reveals tropical lowland insects, vital to ecosystems, have limited ability to adapt to rising temperatures, with up to 52% of future surface temperatures in the Amazon potentially causing heat-related death in half the studied insect community. 与一些高海拔物种不同,低地昆虫在耐热性方面表现出的生理灵活性很小,受稳定蛋白结构的限制,限制了进化适应。 Unlike some high-altitude species, lowland insects show little physiological flexibility in heat tolerance, constrained by stable protein structures that limit evolutionary adaptation. 该研究以非洲和南美洲2 000多个物种为基础,警告气候变化、威胁授粉、分解和食物网导致的昆虫大量死亡。 The research, based on over 2,000 species across Africa and South America, warns of widespread insect die-offs due to climate change, threatening pollination, decomposition, and food webs.
