栖息地的丧失对全球生物多样性构成了重大威胁。许多研究探讨了森林砍伐对动物种群的潜在损害，但很少有人认为树木是温度调节的微栖息地，或解决树木损失如何影响气候变化下物种的命运。使用生物物理的方法，我们探讨树木损失可能会影响半树栖昼夜变温动物（蜥蜴）在当前和预计的气候。我们发现，树木的损失可以减少蜥蜴的活动时间和活动季节的长度的增长。虽然气候变化通常可以促进蜥蜴的种群增长，但森林砍伐可以逆转66%的模拟种群的积极影响，并进一步加速另外18%的种群下降。我们的研究强调了树木可用性与人口生存和增长之间的机械联系，从而倡导森林保护，并将生物物理建模和微生境多样性纳入保护战略，特别是在面对气候变化时。
Habitat loss poses a major threat to global biodiversity. Many studies have explored the potential damages of deforestation to animal populations but few have considered trees as thermoregulatory microhabitats or addressed how tree loss might impact the fate of species under climate change. Using a biophysical approach, we explore how tree loss might affect semi-arboreal diurnal ectotherms (lizards) under current and projected climates. We find that tree loss can reduce lizard population growth by curtailing activity time and length of the activity season. Although climate change can generally promote population growth for lizards, deforestation can reverse these positive effects for 66% of simulated populations and further accelerate population declines for another 18%. Our research underscores the mechanistic link between tree availability and population survival and growth, thus advocating for forest conservation and the integration of biophysical modelling and microhabitat diversity into conservation strategies, particularly in the face of climate change.
