Macropods play an important ecological role in the Australian environment; however, at high
population densities can adversely affect biodiversity and primary production and result in …

Fitness costs of reproduction are expected when resources are limited. Costs drive the
evolution of life‐history strategies and can affect population dynamics if females change …

Dingoes/wild dogs (Canis dingo/familiaris) and red foxes (Vulpes vulpes) are widespread
carnivores in southern Australia and are controlled to reduce predation on domestic …

In variable environments, habitats that are rich in resources often carry a higher risk of
predation. As a result, natural selection should favour individuals that balance allocation of …

A fascinating look at the diverse reproductive strategies of numerous female mammals, from
hyenas to goats, kangaroos to whales. Newborn mammals can weigh as little as a dime or …

Simple Summary Eastern Grey Kangaroos (Macropus giganteus) occur throughout the
seaside town of Anglesea in southern Victoria, Australia. We have tagged about half of these …

Behavioural traits can vary between individuals from the same population. These differences
can involve consistent variation in the level of a particular behaviour (personality) or …

Highlights•We studied wild female eastern grey kangaroos under low predation risk over a
year.•We studied what caused variations of their vigilance and feeding rates.•Vigilance …

The main component of mammalian maternal care is milk production. The composition of
milk has been hypothesized to determine offspring survival, and to vary with offspring sex …

In polygynous species, male reproductive success is predicted to be monopolized by a few
dominant males. This prediction is often not supported, suggesting that ecological and …
