... Characterization of the whole population based on sample groups will always have a representation error, which will change with growth of the sample group size. At a certain point it will be negligible and with further sampling beyond that point the error remains practically unchanged...

... with Sydney at its centre and a radius equal to the distance from Sydney to Kiama: ca. 100 km) in 1788 are compared with those species present or suspected to be present today. Extent of herpetofaunal loss in these reserves over the past 220 years is estimated and correlated with reserve size, showing...

... We radiotracked 18 pet cats Felis catus from rural and urban areas within the City of Armadale, Western Australia, both at night and during the day between August 2003 and February 2005 to estimate the size of buffer zone required to reduce incursions by pet cats into native bushland. Home...

... to 0.7 sheep (in dry sheep equivalents or DSE); however, this value is not supported by most current data. A value for the competitive impact of kangaroos per kg body weight of approximately 0.6 DSE translates into 0.4 DSE when body size is taken into account, kangaroos being much smaller on average than...

... The male reproductive cycle of Tiliqua scincoides scincoides is described on the basis of variation in testis dimensions and testicular and epididymal histology of museum specimens. Sexual maturity occurs at smaller body sizes in southern Australia than in Queensland. Spermatogenesis commences...

... sized remnants may evoke public attention, small developments are often approved without adequate attention to the long term impact on even the threatened species of the Plain. In this paper we provide examples of the way in which remnants that may be only a single housing lot in size, can be habitat...

... and to provide a scientific basis for determining buffer widths around ephemeral streams in the Pilliga State forests of north-west New South Wales. Anabat detectors recorded bat activity over two consecutive nights in one season at each of three dry stream-bed sizes (small, medium and large), clustered...

.... Instead, passerine species richness declined with increasing Distance to Bushland and with increasing Housing Density, but increased proportionately with the Size of, Nearest Bushland > 5ha. Together, these predictors explained approximately half the variability in bird species richness (adjusted R 2...
