Evidence for the occurrence of rumination-like behaviour, or merycism, in the koala (Phascolarctos cinereus, Goldfuss)
This paper provides the ®rst account of merycism in koalas (Phascolarctos cinereus), and in doing so, potentially sheds new light on the occurrence and signi®cance of this behaviour in other herbivorous marsupials. Koalas ®tted with acoustically sensitive transmitters, to monitor mastication and ingestive behaviour, were also found to make bouts of rhythmic `mastication-like' noises that were n...
متن کاملChlamydiaceae and Chlamydia-like organisms in the koala (Phascolarctos cinereus)--organ distribution and histopathological findings.
Chlamydial infections in koalas can cause life-threatening diseases leading to blindness and sterility. However, little is known about the systemic spread of chlamydiae in the inner organs of the koala, and data concerning related pathological organ lesions are limited. The aim of this study was to perform a thorough investigation of organs from 23 koalas and to correlate their histopathologica...
متن کاملAnatomical and Radiological study on the skull of the Koala (Phascolarctos cinereus)
Four koala heads were used with the aim of studying the anatomy and radiology of the skulls. This study may establish baseline data necessary to help in understanding, interpreting x-ray images and treating some of the respiratory diseases or surgical affections of the head. In addition, it may pave the way for future functional and comparative anatomical and radiological studies. The peculiari...
متن کاملthe effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولPhylogeography of the Koala, (Phascolarctos cinereus), and Harmonising Data to Inform Conservation
The Australian continent exhibits complex biogeographic patterns but studies of the impacts of Pleistocene climatic oscillation on the mesic environments of the Southern Hemisphere are limited. The koala (Phascolarctos cinereus), one of Australia's most iconic species, was historically widely distributed throughout much of eastern Australia but currently represents a complex conservation challe...
