16. Lethal bird flu could decimate Oceania's birds. From vigilance to vaccines, here's what we're doing to prepare.

Abstract

The article discusses the threat posed by a new strain of avian influenza, known as Highly Pathogenic Avian Influenza (HPAI) H5N1 2.3.4.4.b, to the bird populations of Oceania. This strain has already caused mass deaths of birds worldwide and has the potential to devastate Australia's unique wildlife and poultry industries if it reaches the country. Australian researchers, governments, veterinarians, and wildlife rehabilitators are actively preparing for its arrival by monitoring for sick birds, implementing biosecurity measures, and considering vaccination trials for captive birds. The article emphasizes the need for vigilance and encourages the public to report any sightings of sick or dead birds. [Extracted from the article]

Abstract

Despite the widespread use of telemetry to track the movements of many different avian species, there are few published studies describing tracking methods for large psittacine birds. Due to their powerful bills and inquisitive demeanours, large parrots m

24. PRESENTATION AND PROGNOSTIC INDICATORS FOR FREE-LIVING BLACK COCKATOOS ( CALYPTORHYNCHUS SPP.) ADMITTED TO AN AUSTRALIAN ZOO VETERINARY HOSPITAL OVER 10 YEARS.

Author

Le Souëf, Anna, Holyoake, Carly, Vitali, Simone, and Warren, Kristin

Abstract

The article presents a case study which investigates the factors that can influence the survivability of black cockatoos (Calyptorhynchuss spp.) in animal rehabilitation centers in Australia. Topics discussed include the use of clinical records from the Perth Zoo Veterinary Hospital to obtain the relevant data, the use of the statistical package SPSS Statistica 17.0 to analyze the acquired data, and a detailed analysis of the results.

25. The functional morphology of the lungs of small Australian passerines having different diurnal activity patterns

Author

Abstract

This thesis examines the relationship between pulmonary microanatomy, metabolic physiology and diurnal activity in Australian passerines. The selected species were sympatric, and were of similar body mass, but differed in the energetic demands of their diurnal routine. The five species selected represented three activity categories: high (Hirundinidae, swallows), moderate (Meliphagidae, honeyeaters) and low (Maluridae, fairy wrens). These classifications were based on literature data, supported by field observation and calculations of flight cost based on measurement of wing morphology. Laboratory metabolism of the five species was quantified by the measurement of standard metabolic rate, and maximal cold-induced metabolic rate. The standard metabolic rates of all except the low activity wrens agreed with allometric predictions for passerine species. The wrens had a significantly lower standard metabolic rate than predicted for passerine species. There was no clear relationship between activity classification and maximal metabolism. The highest maximal metabolic rate was found in the moderately active tawny-crowned honeyeater. The other four species were statistically indistinguishable from one another with regard to this parameter. Maximal metabolic rate was similar across activity categories. The apparent discrepancy in the relationships of standard and maximal metabolism to diurnal activity suggests that standard and maximal metabolism may reflect different anatomical and ecological restrictions. While standard metabolic rate appears to be a good index of daily energetic demand, maximal metabolic rate may reflect the capacity of a species to respond to sudden increases in metabolic demand, such as are associated with fleeing from predators, or sudden changes in atmospheric conditions. Pulmonary anatomy was analysed quantitatively using stereology. Lung volumes, and the proportions of the various lung components discernible at the light microscopy level, were simi

26. Growth and development of captive Geocrinia rosea (Myobatrachidae): A rare species analogue.

Author

Mantellato, Lisa, Gaikhorst, Glen, Kruger, Renee, Vitali, Simone, and Robertson, Helen

Abstract

Using Geocrinia rosea as an analogue of the two threatened frog species, G. alba and G. vitellina, techniques were developed which contribute to an ex situ rearing program. We tested the effect of two levels of enclosure complexity on metamorph growth, and tested the effect of different substrate types on the success of egg clutch hatching and the subsequent development and growth of metamorph frogs. We found that the simplest enclosure was associated with the highest growth rates and better bone density of metamorphs, while a low pH sphagnum peat substrate was the better substrate for egg clutch survival and subsequent growth of metamorphs. Success of the program was highlighted by the rearing of second-generation frogs. These recommendations have now been applied to the captive management of the two endangered Geocrinia species.

27. Exogenous hormones induce poor rates of oviposition in the anurans, Litoria moorei and L. aurea.

Abstract

Combinations of commercially available hormones (luteinising hormone-realeasing hormone agonist, human chorionic gonadotrophin and progesterone) were given intra-coelomically to gravid females of two Australian bell frogs, Litoria moorei and L. aurea. The injections were not sufficient to cause normal ovulation and egg laying in the absence of males. Further studies are still required to develop a safe method of programming ovulation and oviposition in these and other recalcitrant species to obtain eggs that have not been exposed to sperm.
