The European honeybee (Apis mellifera) occurs in both managed and feral colonies across Australia, and as an abundant, generalist introduced species, may adversely effect indigenous Australian bees through competition for flower resources. Reviewing the literature, we found mixed associations between honeybee abundance and native bee abundance, richness or reproduction. Nevertheless, negative associations occurred more often than positive associations, especially for species richness. We provide recommendations for future research.

This study investigates the possibilities of weather conditions and anthropogenic disturbances contributing to two synchronous abortion events in the grey-headed flying-fox (Pteropus poliocephalus). The results suggest that a combination of chronic physiological stress from food shortage and acute stress from anthropogenic disturbance may have precipitated both synchronous abortion events.

This study measured the rate of decay of natural nest hollows and established the minimum and average interval for repairs to natural and artificial nest hollows. It also describes the cost of deployment and maintenance of artificial nest hollows used by Carnaby’s cockatoo relative to the costs of maintaining natural nest hollows.

Metrosideros bartlettii is a critically endangered tree represented by less than 14 individuals in the wild. Due to its self-incompatible breeding system, pollen from an individual from a different population is required to produce viable seed. Short- and long-term pollen storage helps to overcome challenges in cross-pollination both in the wild and in ex situ collections.

This paper presents a revised broad-scale classification of forested wetlands occurring on floodplains in temperate subtropical south-east Australia and identifies relationships with vegetation types of finer thematic scale described in sub-regional classifications in Queensland, Victoria and New South Wales. Patterns in the distribution of forested wetland types are described using statistical models.
