... variables) and by the nature of the data these sampling methods can provide. Capture techniques are the preferred method but capture using mesh (‘gill’) nets is limited by stream flows and the presence of fish and/or large woody debris (‘snags’). Fyke netting, the other preferred method, is largely...

... Wetland classification and assessment of conservation significance are based on criteria that generally exclude one of the largest components of biodiversity in lentic systems: the invertebrates. Preliminary data are presented on sampling efficiency and methods required to describe invertebrate...

.... A graphical method is proposed to identify that point, determining minimum size of the bat sample group needed to provide reliable parasite indices. Calculations with various numbers of microbat hosts and subsequent visual inspection have shown that to obtain a reliable Abundance Index of bat fleas...

... Age can be an important predictor of an individual's survival or reproductive fate and therefore methods for determining ages of wild animals are of general interest. Bats are assigned to age classes based on morphological measurements (e.g. forearm measurement and tooth wear...

... Several techniques were trialed for monitoring the newly-established fur seal haul-out site at Steamers Head, NSW. In order to minimise our impact, we also monitored for any disturbance to seals from our sampling. The site is unusual as while it can only be observed by boat seals perch...

... be developed that can measure natural changes in biodiversity before one will be able to assess whether biodiversity is changing in response to anthropogenic disturbances. Many attempts have been made to reduce the complexity of a species x sample data-matrix, which is the basic measure of biodiversity...

... contrasts with others where quality control is confined to acceptance sampling (another form of SPC) and one-off training. The basic laboratory sorting procedure we have developed is described, as are methods for monitoring error levels. These include control charts and taxonomic breakdown charts...

... collection is seen as a more accurate indicator of species accumulation than year of description. Changing collecting methods and number of new sites sampled have a marked effect on the number of additional species accumulated. About half of all species can be considered rare , being known from 1–3...
