Two closely-related species living in sympatry can only coexist if a shift towards a novel ecological niche occurs. For seabird species breeding in tropical regions, competitive pressures intensify due to high population densities in colonies and spo

The Great Barrier Reef supports significant breeding populations of tropical seabirds; however, recent evidence has indicated declines in seabird populations across some of the most important breeding sites. Evidence for the cause of these significan

Few studies document long-term colony-level metrics from colony establishment to maturity (equilibrium) and few test predictions of general models of colony development. We describe long-term trends in a colony of Australasian Gannets (Morus serrator

Human activity is considered to be a key factor contributing to the worldwide decline in shorebird populations. In order to minimize human disturbance to shorebirds it is important to determine public awareness of shorebirds and shorebird conservatio

Seabirds that forage by plunge diving dive less frequently than those that dive from the water surface, and spend less time in flight than more generalist foragers. We hypothesised that this is due to foraging by plunge diving entailing a high energe

Marsupial research, conservation, and management can benefit greatly from knowledge about glucocorticoid (GC) secretion patterns because GCs influence numerous aspects of physiology and play a crucial role in regulating an animal's response to stress

Age-related improvements in reproductive performance in seabirds have been well documented, and may be explained by improvements in foraging efficiency or increased experience and reproductive effort with age. The interactive effects of parental age

To optimise lifetime reproductive success, individuals must balance current reproductive effort against future reproductive prospects. In birds, incubation and chick-rearing must involve costs, and manipulation of the length of incubation offers an i

The White-faced Storm Petrel (Pelagodroma marina) is restricted to three breeding colonies within Victoria: Mud Islands and South Channel Fort in Port Phillip Bay, and Tullaberga Island off Mallacoota. Numbers of these storm petrels breeding on Mud I

Prey consumption of Australasian gannets (Morus serrator) breeding in Port Phillip Bay, Victoria, was investigated between 1997 and 2000 and the potential overlap between gannets and commercial fisheries in this region was assessed. Approximately 100
