The energy cost of adaptive immune activation in endotherms is typically quantified from changes in resting metabolic rate following exposure to a novel antigen. An implicit assumption of this technique is that all variation in energy costs following

The use of anticoagulant rodenticides to eradicate invasive rodents from islands has become a powerful tool to prevent species extinctions and to restore degraded ecosystems. Success is dependent on all targeted individuals consuming rodenticide and

Little is known of the Endangered Lord Howe Island Cockroach Panesthia lata Walker, 1868, other than that it disappeared from Lord Howe Island following the introduction of ship rats Rattus rattus (Linnaeus, 1758) in 1918. With a rodent-eradication p

SUMMARY Burrow-nesting petrels use their well-developed sense of smell for foraging, homing to their nest, and mate recognition. The chicks of burrow-nesting petrels can apparently learn odours associated with prey while still in the nest, but the de

Summary 1The pituitary hormone prolactin is thought to play an important role in the promotion of parental care in birds and mammals. The level of care parents provide is, however, likely to be influenced by additional factors, such as their physiolo

Many petrels show no obvious sex-linked dimorphism in plumage or size and consequently many researchers fail to sex the living individuals they study. Several methods of sex discrimination that do not rely on plumage- or obvious size-dimorphism can b

The aerobic capacity model proposes that endothermy is a by-product of selection favouring high maximal metabolic rates (MMR) and its mechanistic coupling with basal metabolic rate (BMR). Attempts to validate this model in birds are equivocal and res

Procellariiformes (albatrosses and petrels) must accumulate substantial energy reserves to sustain them while incubating their single egg. They then produce a chick that is often more than 130% of their own body mass. Thus, despite the variable natur

The recent global decline of amphibians has been as pronounced in Australia as anywhere else on earth. Although the exact causes of this decline are uncertain, the translocation of individuals between populations is likely to exacerbate the problem.
