Alien species (pest animals and weeds) are acknowledged widely as a major cause of global biodiversity decline. However, there are very few studies that have quantified the specific biodiversity at […]
Burrowing seabirds are vulnerable to extirpation by introduced predators such as rats, but much evidence of predation is circumstantial. On Taukihepa, an island off southern New Zealand, two possible predators […]
In the present paper, we have provided an initial assessment of the current and future threats to biodiversity posed by introduced mammals (predators and herbivores) inhabiting the Australian rangelands, exploring […]
The viability of Yellow-eyed Penguins Megadyptes antipodes on South Island, New Zealand, is threatened through the loss of breeding habitat by land clearance and the loss of chicks to introduced […]
The spotted-tailed quoll (Dasyurus maculatus) is a medium-sized marsupial carnivore that has declined in abundance and distribution since European settlement in Australia, and is now listed federally as an endangered […]
The scanning and flight behaviour of birds that forage in flocks may be influenced by several variables, including the size of the flock and the presence of visual obstructions. Visual […]
This study tested the efficacy of secondary poisoning using Talon 20 P™ (20 ppm brodifacoum) in bait stations for killing predators in a New Zealand podocarp forest. Nine of 10 […]
Few quantitative data exist regarding the impact of the introduced cane toad, Bufo marinus, on native Australian fauna. This study investigated predation by tadpoles of B. marinus and two native […]
This study investigated the population dynamics of three species of dasyurid marsupials in sand ridge habitat of the Simpson Desert, western Queensland, over a 10-year period between March 1990 and […]
Rabbit haemorrhagic disease (RHD) has reduced populations of rabbits (Oryctolagus cuniculus) across most rabbit-prone short-tussock grasslands of New Zealand, at scales rarely seen there before. Flow-on effects to other parts […]
Every year in Australia approximately 11 million lambs die within a week of birth. Of these, 5% die before birth, 20% during birth and 75% after birth. This lamb mortility […]
Wild dogs are a widespread problem in Australia. Agricultural impacts of wild dogs are severe and they can cause stock losses of up to 30% in some areas. Wild or […]
Two types of numerical response function have evolved since Solomon first introduced the term to generalize features of Lotka-Volterra predator-prey models: (i) the demographic numerical response, which links change in […]
