The Resilience of Tropical Forest Invertebrates to Microclimate Change

This dataset examines the thermal physiology of ants accross the SAFE project, with the goal of understanding how changing microclimates affect communities of invertebrates in disturbed landscapes. Tropical invertebrates are expected to already live close to their upper thermal tolerances, and so the rapid changes to microclimate brought about by logging may be a powerful determinant of the emergent communites in disturbed forests. The worksheet contains the upper critical temperature (CTmax) of individual ants identified to genus level. Ants were collected from the ground or soil layer unless specified as arboreal. CTmax was determined using a ramping procedure whereby temeprature was increased from 32 degrees upwards at a rate of 0.2 degrees per minuted until individuals lost motor control. Ants were found by searching opportunistically throughout entire blocks, therefore for locations we have simply inputted one large fractal order from each sampling block used.

本数据集基于SAFE项目考察蚂蚁的热生理学特征，旨在探究微气候变化如何影响受干扰景观中的无脊椎动物群落。热带无脊椎动物的生存环境被认为已接近其热耐受上限，因此伐木导致的微气候快速变化可能是受干扰森林中新生群落构成的关键决定因素。工作表包含已鉴定至属级的单只蚂蚁的临界高温上限（CTmax）数据。除非明确标注为树栖，否则蚂蚁样本均采自地面或土壤层。CTmax通过温度梯度升温法测定：从32℃开始，以每分钟0.2℃的速率升温，直至蚂蚁失去运动控制能力。蚂蚁通过在整个样区的随机搜索采集，因此在位置信息栏中，我们仅录入了每个采样区块对应的一个大分形阶数。
