The study of amphibian spatial behaviour provides key information for species conservation. Most commonly used techniques to track amphibians are either unsuitable for small species or fail to give sufficiently fine-resolution data of habitat use. We report on the use of non-toxic fluorescent powders to track the fine-scale movement of a threatened New Zealand frog, Leiopelma pakeka.
GPS and satellite technology for studies on wildlife have improved substantially over the past decade. It is now possible to collect fine-scale location data from migratory animals, animals that have previously been too small to deploy GPS devices on, and other difficult-to-study species. Often researchers and managers have formatted well-defined ecological or conservation questions prior to deploying GPS on animals, whereas other times it is arguably done simply because the technology is now available to do so.
The Wellington tree weta, Hemideina crassidens, is a harem-polygynous nocturnal insect whose males defend and mate groups of females residing in cavities in trees. In this study I examined sexual differences in gallery use (number of galleries occupied per unit time), distance travelled per night and activity patterns after sunset. In addition, I investigated how gallery size affected each of these variables.
