Resource specialists lead local insect community turnover associated with temperature - analysis of an 18-year full-seasonal record of moths and beetles.

摘要: Insect responses to recent climate change are well documented, but the role of resource specialization in determining species vulnerability remains poorly understood. Uncovering local ecological effects temperature with high-quality, standardized data provides an important first opportunity for predictions about specialists, and long-term time series essential revealing these responses. Here, we investigate temperature-related changes insect communities, using a sampling site more than quarter-million records from two decades (1992-2009) full-season, quantitative light trapping 1543 moths beetles. We investigated annual as fauna composition, abundance phenology climate-related context affinities data. Finally, explored dietary specialization. Across both beetles, affinity specialists increased through net gain hot-dwelling loss cold-dwelling species. The composition generalists remained constant over time. observed increase richness groups. Furthermore, divergent phenological between cold- species, advancing delaying their relative abundance, respectively. Phenological advances were particularly pronounced cold-adapted specialists. Our results suggest explaining compositional communities increases. propose that particular affected by increase, leading distinct temperature-mediated turnover seen this group. number could have been facilitated dissimilar utilization expanded growing season hot-adapted indicated oppositely directed An especially advancement suggests such might help minimize further temperature-induced Although limited single study site, our several concordance expected larger-scale
