... free-range systems. Papua New Guinea's human health system and the animal health field and laboratory services are resource-limited and are facing many human and animal disease challenges. The Fleming Fund Country Grant, implemented by the Burnet Institute Australia, is working with Papua New Guinea...

..., but they may nevertheless require a legal, transportable and reliable method to be available for them so that they can obtain the necessary approvals to undertake their work. A small CO 2 system, reproducing the recommended method used widely in laboratories, seemed likely to meet these requirements. Three...

... and laboratory rat, Rattus norvegicus , fur was severely compromised by longer-term preservation in ethanol. Both chemical and alum tanning eliminated the blue-white photoluminescence of rat fur, but not the pink photoluminescence of bandicoot fur. The results of these small-scale tests indicate that museum...

..., degradation from light exposure is an unquantified contributor to false negatives in museum-based surveys. I tested the resistance of pink photoluminescent bandicoot, Peramelidae, fur to exposure to natural sunlight and artificial laboratory lighting. Photoluminescence underwent visibly noticeable...

... by the 2019–2020 bushfires. The tests were conducted under controlled laboratory conditions to investigate the thermal response of different designs to radiant heat and changes in ambient temperature. We examined how paint type (i.e., no paint, white exterior paint, and reflective white paint), insulation...

.... Our study covered a range of ecosystem types over an area of approximately 20,400 km 2 . We searched 70 survey sites that differed in burn severity for all species of land snail visually on-site and by sifting leaf litter samples under a microscope in the laboratory. These survey sites were selected...

... aurea was once abundant, there is some suspicion that G. holbrooki's non-specific predatory behaviour may be instrumental in the decline of L. aurea . Laboratory and field experiments were conducted to assess the impact of G. holbrooki predation on L. aurea tadpole survivorship. Laboratory trials...

... an instance of a Jacky Lizard foraging on abundant mating bibionid flies Bibio imitator amongst remnant vegetation in an urban environment. Small black ants, which were also present, were not consumed. Foraging techniques were similar to those observed by another study in laboratory conditions, but potential...

... was largely dry and had only small isolated pools. We found 53 invertebrate taxa including the larvae of the dragonfly Austrogynacantha heterogena and one vertebrate species (larvae of the frog Litoria rubella ) in the pool-water samples. Artificial inundation of the lake sediment samples under laboratory...

... mammals ( Capra , Cervidae, Felis , Lagomorpha, Muridae and Sus ), and excluded agricultural (Animal Production) and laboratory-based studies. The majority of published studies surveyed focussed on the conservation impacts of exotic mammals and their management, while very few articles used exotic mammals...

... mosquitoes. Other frog species, such as Striped Marsh Frog Limnodynasres peronii and Peron's Tree Frog Litoria peranii have not apparently suffered from this predation to the same degree. Laboratory experiments were undertaken in order to evaluate the extent t o which predation on eggs, fry and tadpoles of L...

... of the laboratory experiments and field surveys are consistent with the hypothesis that G. hoibrooki is contributing to declining frog populations. Does predation by the fish Gambusia holbrooki (Atheriniformes: Poeciliidae) contribute to declining frog populations? Cameron a n d Jean Jossl 'School rrf Bi18logic~l...

...L. E. L. M. Crowley; W. Ivantsoff Reproductive behaviour, colouration of adult fish and development to hatching of Melanotaenia nigrans and Melanotaenia splendida inornata were studied under laboratory conditions during summer and autumn (February to early May). At 26°C ± 1°C, all observed pairs...

...Matthew Greenlees; Michael Crossland; Richard Shine The viability of a metamorph anuran can be influenced by its body size and the time it has taken to complete larval development. In a laboratory experiment, we show that the presence of tadpoles of the invasive Cane Toad Rhinella marina causes...
