Genetic diversity in natural and introduced island populations of koalas in Queensland.
Lee, K. E.; Seddon, J. M.; Johnston, S.; FitzGibbon, S. I.; Carrick, F.; Melzer, A.; Bercovitch, F.; Ellis, W.; CSIRO, Collingwood, Australia, Australian Journal of Zoology, 2012, 60, 5, pp 303-310, many ref. Island populations of animals are expected to show reduced genetic variation and increased incidence of inbreeding because of founder effects and the susceptibility of small populations to the effects of genetic drift. Koalas (Phascolarctos cinereus) occu...

Twenty-five new polymorphic microsatellites for the eastern mosquitofish, Gambusia holbrooki (Actinopterygii:Poeciliidae), an invasive species in Australia.
Umbers, K. D. L.; Jennions, M. D.; Gardner, M. G.; Keogh, J. S.; CSIRO, Collingwood, Australia, Australian Journal of Zoology, 2012, 60, 4, pp 235-237, 12 ref. We isolated 25 new polymorphic microsatellite markers from the eastern mosquitofish, Gambusia holbrooki. Initially, 454 shotgun sequencing was used to identify 1187 loci for which primers could be designed. Of these 1187, we trialled 48 in the target spec...

Glochidia ecology in wild fish populations and laboratory determination of competent host fishes for an endemic freshwater mussel of south-western Australia.
Klunzinger, M. W.; Beatty, S. J.; Morgan, D. L.; Thomson, G. J.; Lymbery, A. J.; CSIRO, Collingwood, Australia, Australian Journal of Zoology, 2012, 60, 1, pp 26-36, many ref. Glochidia (parasitic larvae) of freshwater mussels generally require a fish as a host. Westralunio carteri Iredale, 1934 (Bivalvia: Hyriidae), the only freshwater mussel found in south-western Australia, was listed as Vulnerable, but recently changed to L...

Reversed sexual dimorphism and altered prey base: the effect on sooty owl (Tyto tenebricosa tenebricosa) diet.
Bilney, R. J.; White, J. G.; Cooke, R.; CSIRO, Collingwood, Australia, Australian Journal of Zoology, 2011, 59, 5, pp 302-311, many ref. The ecology and function of many Australian predators has likely been disrupted following major changes in prey base due to declines in distribution and abundance of small mammals following European settlement. This study investigated various aspects of t...

Habitat use, population dynamics and species identification of mulgara, Dasycercus blythi and D. cristicauda, in a zone of sympatry in central Australia.
Pavey, C. R.; Nano, C. E. M.; Cooper, S. J. B.; Cole, J. R.; McDonald, P. J.; CSIRO Publishing, Collingwood, Australia, Australian Journal of Zoology, 2011, 59, 3, pp 156-169, 41 ref. Dasycercus cristicauda and Dasycercus blythi are significant mesopredators in arid Australia and both species are threatened nationally. We investigated size dimorphism, habitat use, and population dynamics of sympatric populations during a low rainfall p...

Worker heterozygosity and immune response in feral and managed honeybees (Apis mellifera).
Lowe, E. C.; Simmons, L. W.; Baer, B.; CSIRO Publishing, Collingwood, Australia, Australian Journal of Zoology, 2011, 59, 2, pp 73-78, many ref. Genetic diversity in workers influences colony immunity in several species of eusocial insects. Much less work has been conducted to test for comparable effects of worker heterozygosity, a measure of genetic diversity within an individual. Here we present...

The mongoose in Australia: failed introduction of a biological control agent.
Peacock, D.; Abbott, I.; CSIRO Publishing, Collingwood, Australia, Australian Journal of Zoology, 2010, 58, 4, pp 205-227, 40 ref. We reviewed historical literature and obtained nearly 200 records of the mongoose in Australia up to 1942. Although the earliest importations (from 1855) were for its snake-killing prowess, often as entertainment, its perceived potential as a control agen...

Positive and negative effects of phoretic mites on the reproductive output of an invasive bark beetle.
Hodgkin, L. K.; Elgar, M. A.; Symonds, M. R. E.; CSIRO Publishing, Collingwood, Australia, Australian Journal of Zoology, 2010, 58, 3, pp 198-204, 41 ref. When multiple species coexist upon a single host, their combined effect on the host can be unpredictable. We explored the effect of phoretic mites on the reproductive output of the five-spined bark beetle, Ips grandicollis. Using correlative approaches an...

Hollow-using vertebrate fauna of Tasmania: distribution, hollow requirements and conservation status.
Koch, A. J.; Munks, S. A.; Woehler, E. J.; CSIRO Publishing, Collingwood, Australia, Australian Journal of Zoology, 2008, 56, 5, pp 323-349, many ref. In Tasmania, a considerable proportion of the forested landscape is available for land clearance and production forestry, which has and will continue to result in a decline in hollow availability unless managed appropriately. All hollow-using species are ...

Occurrence of Angiostrongylus species (Nematoda) in populations of Rattus rattus and Rattus fuscipes in coastal forests of south-eastern Australia.
Stokes, V. L.; Spratt, D. M.; Banks, P. B.; Pech, R. P.; Williams, R. L.; CSIRO Publishing, Collingwood, Australia, Australian Journal of Zoology, 2007, 55, 3, pp 177-184, 36 ref. The distributions of the introduced nematode parasite, Angiostrongylus cantonensis, and the native Angiostrongylus mackerrasae in Australia are poorly understood. We sampled rodents and/or their faeces, and intermediate gastropod hosts for the presence of...
