Interspecific variation in life-history traits and physiological limits can be linked to the environmental conditions species experience, including climatic conditions. As alpine environments are particularly vulnerable under climate change, we focus on the montane-alpine fly . Here, we characterized some of its life-history traits and physiological limits and compared these with those of other drosophilids, namely , , and . We assayed oviposition rate, longevity, productivity, development time, larval competitiveness, starvation resistance, and heat and cold tolerance. Compared with the other species assayed, is less fecund, relatively long-living, starvation susceptible, cold adapted, and surprisingly well heat adapted. These life-history characteristics provide insights into invertebrate adaptations to alpine conditions which may evolve under ongoing climate change.
生活史特征和生理极限的种间差异可能与物种所经历的环境条件有关，包括气候条件。由于高山环境在气候变化下特别脆弱，我们聚焦于山地-高山果蝇。在此，我们描述了它的一些生活史特征和生理极限，并将这些与其他果蝇物种（即 、 和 ）的特征进行了比较。我们测定了产卵率、寿命、繁殖力、发育时间、幼虫竞争力、抗饥饿能力以及耐热和耐寒能力。与所测定的其他物种相比， 繁殖力较低、寿命相对较长、易受饥饿影响、适应寒冷，且令人惊讶地适应高温。这些生活史特征为无脊椎动物对高山条件的适应提供了见解，而这些适应可能会在持续的气候变化下发生进化。
