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600公里长的北澳热带样带（Northern Australian Tropical Transect, NATT）设置5个采样点位，每个点位分别布设1公顷的沙地、壤土与黏土样地，采用陷阱诱捕器（pitfall trap）分三次进行采样，以调查蚂蚁的物种丰富度与物种组成，解析区域物种多样性水平。研究点位分布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特征，采样范围覆盖南纬12°50′（年平均降雨量1400毫米）至南纬17°21′（年平均降雨量650毫米）。本项目采集的相关数据可被重复利用，以蚂蚁作为指示类群，构建生物多样性对气候变化与人为干扰的响应模型。本项目属于北澳热带样带（NATT）研究的一部分。请通过以下链接获取该数据集：http://aekos.org.au/collection/csiro/natt/ants9697
