... ) in suppressing Red Fox ( Vulpes vulpes ) populations in Australia has been investigated, with various data tending to show an inverse relationship between densities of the two species (e.g. Letnic et al. 2012; Johnson and VanDerWal 2009).

Egg-laying occurred during two clearly defined periods each year; with peaks...

Nests were built in the trees that dominated colony sites and differed between locations. Red Morrel was the most frequent species at Norseman...

... that landscape connectivity increased the spread and the density of the invasive red fire ant (Solenopsis invicta) which in turn reduced the species diversity in the newly-colonised patches compared to before invasion. Red fire ant is one of the major biosecurity threats in Australia with recent outbreaks...

To determine if there were differences in turtle numbers between 1996 1997 and 2008, the data sets were standardised...

Three wound sites were located and photographed: paired puncture wounds on the neck (37.0mm apart, centre-to-centre; Figure 1b) and thigh (35.6mm; Figure 1c), and a single puncture wound on the upper abdomen/caudal rib region (Figure 1d). The Red Fox was otherwise in good...

The Invasive Animals Cooperative Research Centre (IA CRC 2010) stated that more than 90% of invasive organism impacts in Australia are confined to just five species: red fox (Vulpes vulpes...

... population viability would also be compromised. This argument can be countered by the persistence of populations under harvesting without any obvious impairment to reproduction. Nevertheless, an interesting question is how age influences reproductive output. In this study, data collected from a number of red...
