Abstract

Insects have major impacts on forest ecosystems, from herbivory and soil-nutrient cycling to killing trees at a large scale. Forest insects from temperate, tropical, and subtropical regions have evolved strategies to respond to seasonality; for example, by entering diapause, to mitigate adversity and to synchronize lifecycles with favorable periods. Here, we show that distinct functional groups of forest insects; that is, canopy dwellers, trunk-associated species, and soil/litter-inhabiting insects, express a variety of diapause strategies, but do not show systematic differences in diapause strategy depending on functional group. Due to the overall similarities in diapause strategies, we can better estimate the impacts of anthropogenic change on forest insect populations and, consequently, on key ecosystems.

森林昆虫的季节性:为什么要停歇?
昆虫对森林生态系统有重大影响,从食草和土壤养分循环到大规模杀死树木。温带、热带和亚热带地区的森林昆虫已经进化出应对季节性的策略,例如,通过进入休眠期来缓解逆境,并使生命周期与有利时期同步。在这里,我们展示了森林昆虫的不同功能群,即树冠栖息昆虫、树干相关物种和土壤/粪便栖息昆虫,它们表达了各种不同的休眠策略,但并没有显示出不同功能群在休眠策略上的系统性差异。由于停歇策略的总体相似性,我们可以更好地估计人为变化对森林昆虫种群的影响,进而对关键生态系统的影响。

期刊介绍: Trends in Ecology & Evolution (TREE) is a comprehensive journal featuring polished, concise, and readable reviews, opinions, and letters in all areas of ecology and evolutionary science. Catering to researchers, lecturers, teachers, field workers, and students, it serves as a valuable source of information. The journal keeps scientists informed about new developments and ideas across the spectrum of ecology and evolutionary biology, spanning from pure to applied and molecular to global perspectives. In the face of global environmental change, Trends in Ecology & Evolution plays a crucial role in covering all significant issues concerning organisms and their environments, making it a major forum for life scientists.
