Abstract Cutaneous lesions were observed in a wild population of freshwater turtles during routine disease surveillance at Alligator Creek, Townsville, Australia. Previous attempts to identify the causative agent these unsuccessful; however, existing evidence suggests viral etiology. To further investigate events, blood samples and lesion, oral cloacal swabs collected from 128 two locations (Al...
South America presents the greatest Psittacidae diversity in world, but also has highest numbers of threatened parrot species. Recently, exotic viruses have been detected captive native psittacine birds Brazil, however, their impacts on health wild parrots are still unknown. We evaluated presence Chlamydia psittaci, Psittacid alphaherpesvirus 1 (PsHV-1), avipoxvirus and beak feather disease vir...
Marek's disease (MD), caused by Marek's disease virus (MDV), a poultry-borne alphaherpesvirus, is a devastating disease of poultry causing an estimated annual loss of one billion dollars to poultry producers, worldwide. Despite decades of control through vaccination, MDV field strains continue to emerge having increased virulence. The evolutionary mechanism driving the emergence of this continu...
Blubber Testosterone: A Potential Marker of Male Reproductive Status in Short-Beaked Common Dolphins
A novel molecular technique was used to measure blubber testosterone (BT) in 114 male short-beaked common dolphins, Delphinus delphis, collected from incidental fishery bycatch and strandings. When these concentrations were compared across maturity states, the mean (± SEM) BT levels of mature D. delphis (14.3 ± 3.0 ng/g) were significantly higher than those of pubertal (2.5 ± 0.5 ng/g, P = 0.00...
Here we report that synchronous surfacing in male bottlenose dolphins is associated with alliance membership and that synchrony between members of cooperating alliances is more common during social behaviour than during nonsocial behaviour, especially during bouts of ‘intense’ social behaviour (e.g. mounting, displays, chasing) with female consorts. Alliances of three males varied in the degree...
We inferred the population densities of blue whales (Balaenoptera musculus) and short-beaked common dolphins (Delphinus delphis) in the Northeast Pacific Ocean as functions of the water-column's physical structure by implementing hierarchical models in a Bayesian framework. This approach allowed us to propagate the uncertainty of the field observations into the inference of species-habitat rela...
