The spread of European settlement across the Australian continent has affected not only the faunal and floristic components of the mainland, but has also influenced our island assemblages of native animals. The Fauna of King Island; a guide to identification and conservation management, provides an overview of the history, ecology and conservation management of the King Island fauna. The book discusses both vertebrate and invertebrate fauna for the terrestrial and freshwater habitats of the island and serves as a foundation for identification and management.

The invertebrate fauna of freshwater habitats on the Isle of May, Scotland was investigated and compared with the results from surveys undertaken in 1958. Overall, the freshwater invertebrate fauna appears to be diminished. However, several species were recorded as new to the Isle of May. Although the reasons for the apparent decline in freshwater invertebrates on the island are unclear, an increase in the temporary nature of the habitats due to climate warming may be a contributing factor.

Preferential Water

The woylie (Bettongia penicillata) was once common and abundant over the southern third of the Australian continent. Since European settlement the range of this rat-kangaroo has become reduced by more than 97%, and until the early 1990s, only 3 small natural populations remained, all in south-western Australia. These medium-sized (c. 1 kg) marsupials create a large number of diggings as they forage for the hypogeous fruiting bodies of ectomycorrhizal fungi upon which they feed. The effect of such foraging activity on the availability of plant nutrients in the vicinity of such diggings was evaluated in simulated digging experiments. Available nitrate, ammonium, and sulfur decreased significantly 3 years after diggings were constructed and had filled in, whereas phosphorus, potassium, iron, and organic carbon remained unchanged. The results suggest that preferential water infiltration via woylie diggings leads to a decrease in those soil nutrients that are susceptible to leaching and indicates that digging vertebrates may influence the distribution of surface soil nutrients.

A field survey for the invertebrate fauna conducted in the Ma River, Thanh Hoa province in 2013. The research applied multivariable analysis performed by the Primer v.6 software, such as CLUSTER, one-way ANOSIM, BEST and DIVERSE. The results showed a list of 138 aquatic invertebrate species. Of these, most were freshwater wide-distributing species coupled with others characterized for brackish and marine waters. The biodiversity status was quite high compared to several other rivers in the North of Vietnam. The list contained many economic-valued species and 2 of these were listed in the Red Data Book of Vietnam. The aquatic invertebrates showed a significant relation to the two different combinations of physiochemical factors for zooplanktons and zoobenthos, respectively. The values of the species number, abundance and Shannon-Weiner index for both of zooplanktons and zoobenthos showed a curved trend from the upper river segments to lower river segments. These figures for zooplanktons peaked in the middle river segments, whereas the numbers for zoobenthos achieved the highest numbers in the estuaries. The species composition of the estuaries differentiated significantly from that of other freshwater habitats.

New Vision

Australian politics is often characterized as derivative, pragmatic, and utilitarian—as insufficiently interesting or important to devote much time to. This Handbook challenges that contention, arguing it reflects a narrow, colonial perspective and ignores the richness and diversity of the deep-time history of the Australian continent and the unique inheritance the blending of Australia’s many histories and traditions has produced. Australian political studies encompasses a broad family of research disciplines, whose diverse and methodologically plural efforts have transformed our understanding of Aboriginal cultures and of European settlement. This volume’s thematic approach captures the politics, policies, and societies that have evolved in Australia’s many different landscapes and places. Its chapters present a theoretically rigorous, empirically informed, and historically nuanced account of what is distinctive about Australian politics, its capacity for democratic innovation and what accounts (its many shortcomings notwithstanding), for the resilience of its political traditions and Australia’s relative success.

Terrestrial Biodiversity

Central Australia supports a restricted but important range of freshwater systems, including small, permanent spring-fed streams and larger riverine pools ranging from permanent to ephemeral. These sites support a significant percentage of the aquatic and terrestrial biodiversity within the region. Comparison of records from the first exploratory scientific expedition to the area in 1894, and surveys conducted in 1986, 1994 and 2008, revealed the persistence of the aquatic invertebrate fauna, despite the recent impacts of European settlement. The presence of aquatic insects with Gondwanan origins suggests affinities with assemblages present in a much wetter era (~18 000 years ago). Persistence can be attributed to multiple environmental and social factors, including the role of local aquifers in sustaining permanent systems, the remote and inaccessible nature of the sites, and the protection and management afforded by reservation within national parks. Characterisation of the drivers and stressors that influence these ecosystems suggests that climate change could potentially result in a loss of endemic and relictual species. Hence, the relictual waterbodies of central Australia can be viewed as potential ‘sentinel’ sites for assessing the impacts of changing conditions.

The Subject

The Australian continent provides a unique perspective on the evolution and ecology of carnivorous animals. In earlier ages, Australia provided the arena for a spectacular radiation of marsupial and reptilian predators. The causes of their extinctions are still the subject of debate. Since European settlement, Australia has seen the extinction of one large marsupial predator (the thylacine), another (the Tasmanian devil) is in danger of imminent extinction, and still others have suffered dramatic declines. By contrast, two recently-introduced predators, the fox and cat, have been spectacularly successful, with devastating impacts on the Australian fauna. Carnivores of Australia: Past, Present and Future explores Australia's unique predator communities from pre-historic, historic and current perspectives. It covers mammalian, reptilian and avian carnivores, both native and introduced to Australia. It also examines the debate surrounding how best to manage predators to protect livestock and native biodiversity. Wildlife managers, academics and postgraduate students will benefit from the most up-to-date synthesis by leading researchers and managers in the field of carnivore biology. By emphasising Australian carnivores as exemplars of flesh-eaters in other parts of the world, this book will be an important reference for researchers, wildlife managers and students worldwide.

Special Relevance

The value of distinguishing between plant species regarded as ‘native’ and ‘alien’ has special relevance in the island continent of Australia, where European settlement was a springboard for human-assisted plant dispersal. The year of European settlement is proposed here as providing a distinction between a ‘native’ and ‘naturalised’ flora and is applied for the entire Australian flora of vascular plants. Herbarium collections and ecological criteria were employed to determine the status of 168 species of ambiguous origin. The date of 1788 proved to be a relatively straightforward criterion to assign native and naturalised status and the origin of only 27 plant species remains ambiguous. The dispersal of plants between continents is an ongoing process but European settlement of the Australian continent represents a very sharp biogeographic event for the Australian flora and provides a straightforward criterion for determining the ‘naturalised’ species.
