Contrasting genetic structuring between colonies of the world's smallest penguin, Eudyptula minor (Aves: Spheniscidae)

The Little Penguin, Eudyptula minor, is a seabird that nests in colonies throughout New Zealand and southern Australia. Individuals from different colonies in southeast Australia differ significantly in morphology and ecology, suggesting that some genetic structuring may exist among colonies. In contrast, the marking of individuals with flipper bands has revealed some, albeit infrequent, movement between colonies. To determine the extent of genetic structuring, we tested the null hypothesis of substantial gene flow within southeast Australia by examining patterns of genetic variation across seven colonies separated by up to 1,500 km. Phylogeographic structuring was absent for mitochondrial control region sequences (2–3 individuals per colony). Microsatellite allele frequencies at five loci and mitochondrial haplotype frequencies (50 individuals per colony) were also homogenous among the majority of colonies sampled, although two colonies at the western periphery of the sampling range were distinct from those to the east. The genetic homogeneity among the majority of colonies can be explained by low but consistent contemporary gene flow among them, or a recent founder event in Bass Strait following the last marine transgression. The genetic break towards the western end of the sampling distribution appears best explained by differences in sea surface temperature and, consequentially breeding phenology, the latter hindering genetically effective migration.

Diet of an eastern barn owl Tyto javanica on the Patho Plains, northern Victoria

A small sample of eastern Barn Owl Tyto javanica pellets, from native grasslands on the Patho Plains in northern Victoria in February 2007, contained the remains of 48 prey individuals: 38 Australian Plague Locusts Chortoicetes terminifera, nine house Mice Mus domesticus and one Fat-tailed dunnart Sminthopsis crassicaudata. Such a high proportion of locusts in the eastern Barn Owl's diet is noteworthy, and is discussed in the context of recent locust-spraying operations in the region.

Jump over the gorge : overcoming cultural gap in doing business with China

China has become a synonym for future business growth. It is the business nirvana of the 21st century (Chung 2004). As a major emerging market, China offers many companies great potential in their future growth. China's economic growth has been consistently double digits for the past two decades. China has become an economic power in the world. To Australia, China became its largest trading partner since 2007. While other parts of the world are experiencing economic down tum, e.g. the US and UK, Australia still enjoys its longest lasting economic growth. Much of the growth is largely built on this Chinese demand of minerals (Kirk 2004). Therefore research of Australian companies' internationalisation into China is timely and in high demand. 40 Australian companies' were investigated in a recent research conducted in July - December 2007. Among many findings through the research, one of the major issues was the impact of cultural differences on companies in their operations. The research discovered the gap of cultural differences between Australia and China is large which has caught many companies by surprise. Further the inability to deal with this large cultural gap as well as being properly prepared for the cultural issue they are about to encounter prior to entering into the Chinese market may cause serious issues on performance. It is through this research an important finding is presented that engaging culturally skilled consultants when dealing with Chinese market is an effective and cost efficient way of conducting businesses in China.
