Population and trait dynamics of hosts and parasitoids from an 18-month microcosm experiment under gradually increasing temperature to plus 2 or 4 degrees Celsius

This dataset contains population and trait dynamic and life history data of the host organism Indian meal moth Plodia interpunctella, and its parasitoide wasp Venturia canescens in response to temperature changes, from an 18-month microcosm experiment. Variables in this dataset include weekly dead adult count of hosts or parasitoids, leg length (proxy to adult body size), and multi-variate life history measures (survival, development time, sizes). During the experiment, lines of hosts, with or without parasitoids, were exposed to gradual increases in temperature at either +2 or +4 degrees celsius over 18 months, in the presence or absence of stochastic fluctuations. This dataset was created as part of a study to investigate the impact of long-term climate warming on generational multispecies interactions, The data will be beneficial for any studies related to population cycles, long-term dynamics, density-dependence responses and climate change projection.

本数据集源自一项为期18个月的微宇宙实验，涵盖宿主生物印度谷螟（Plodia interpunctella）及其寄生蜂刻绒茧蜂（Venturia canescens）在温度变化下的种群动态、性状动态与生活史数据。数据集包含的变量包括宿主或寄生蜂的周度成虫死亡数、足长（作为成虫体型的替代指标），以及多变量生活史指标（存活率、发育时长、体型大小）。实验过程中，设置携带或不携带寄生蜂的宿主株系，在18个月的周期内以2℃或4℃的升温速率逐步提升环境温度，并设置是否存在随机温度波动的处理条件。本数据集作为一项探究长期气候变暖对跨世代多物种互作影响的研究的组成部分构建而成。该数据集可用于与种群周期、长期动态、密度制约响应以及气候变化预估相关的各类研究。
