Commonwealth Scientific and Industrial Research Organisation (CSIRO) and North Australian Tropical Transect (NATT) - Ant data (1996-1997)

In this survey, ant species richness and composition was sampled using pitfall traps on three occasions at 1-ha sand, loam and clay sites at each of five locations along the 600 km Northern Australian Tropical Transect (NATT) to determine species diversity. Study locations are located along a bioclimatic gradient of increasing latitude and decreasing rainfall in the Australian tropical savannas, from 12°50' S (1400 mm mean annual rainfall) to 17°21' S (650 mm). The collected data could be re-used to model biodiversity responses to climate change and disturbance, using ants as an indicator taxon.

本调查沿全长600 km的澳大利亚北部热带样带（Northern Australian Tropical Transect, NATT）设置5个采样点位，每个点位布设1公顷的沙地、壤土与黏土样地，分三次采用陷捕器（pitfall trap）采集蚂蚁样本，以获取其物种丰富度与物种组成数据，进而探究蚂蚁的物种多样性特征。各研究点位坐落于澳大利亚热带稀树草原的生物气候梯度上，呈现纬度升高、年降雨量逐步降低的变化趋势，采样覆盖范围从南纬12°50′（年平均降雨量1400 mm）延伸至南纬17°21′（年平均降雨量650 mm）。本次采集得到的数据集可被重复利用，以蚂蚁作为指示分类单元（indicator taxon），模拟生物多样性对气候变化与干扰活动的响应机制。本项目为澳大利亚北部热带样带（NATT）研究计划的组成部分。
