Foraging activity of Western Cape ant species at different temperatures

This excel workbook contains the density of foragers of Western Cape ant species at different temperatures. Observations were made in 13 sites in the Fynbos and Succulent Karoo Biomes in spring, summer, autumn, and winter to get a range of temperatures and environmental conditions. Surveys were made at different times of the day and where possible also after sunset. Three different bait types were used to attract a wide variety of ant species. Foraging densities are calculated as numbers of ants foraging at a certain temperature divided through number of baits available to it at te temperature. The latter takes into account that species only occurred in some sites and many did not use all bait types. The work was conducted by Brigitte Braschler as part of her postdoctoral studies at the CIB at Stellenbosch University under the supervision of Steven L. Chown.本Excel工作簿收录了西开普省不同温度下蚁类觅食者的种群密度。研究于春季、夏季、秋季、冬季在凡波斯（Fynbos）与肉质卡鲁（Succulent Karoo）生物群系的13个样地开展，以覆盖不同温度与环境条件区间。调查于一日内不同时段开展，条件允许时也会在日落之后进行。本次研究采用三种不同的诱饵类型，以吸引更多样的蚁类物种。觅食密度的计算方式为：特定温度下的觅食蚂蚁数量，除以该温度下可获得的诱饵数量。该分母项的设置考虑到：部分蚁类仅在部分样地分布，且多数蚁类不会取食全部三种诱饵类型。本研究由Brigitte Braschler完成，是她在斯泰伦博斯大学CIB开展的博士后研究的一部分，研究受Steven L. Chown指导。
