... of the difficulties associated with sampling invertebrates in foraging pits. Bilbies were reintroduced into a rangeland restoration program in Western Australia, providing an opportunity to compare invertebrates in their foraging pits with the undisturbed surface soil. The challenge was to develop a method...

... sampling is labour-intensive and attained sample size is often not large enough to detect all species present. Therefore, we applied integrated rarefaction and extrapolation sampling curves and asymptotic analysis to estimate species richness. We observed 103 species of rotifers, 29 species of cladocerans...
