Download or read book Australian Deserts written by Steve Morton and published by CSIRO PUBLISHING. This book was released on 2022-02 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Australian Deserts: Ecology and Landscapes is about the vast sweep of the Outback, a land of expanses making up three-quarters of the continent – the heart of Australia. Steve Morton brings his extensive first-hand knowledge and experience of arid Australia to this book, explaining how Australian deserts work ecologically. This book outlines why unpredictable rainfall and paucity of soil nutrients underpin the nature of desert ecosystems, while also describing how plants and animals came to be desert dwellers through evolutionary time. It shows how plants use uncertain rainfall to provide for persistence of their populations, alongside outlines of the dominant animals of the deserts and explanations of the features that help them succeed in the face of aridity and uncertainty. Richly illustrated with the photographs of Mike Gillam, this fascinating and accessible book will enhance your understanding of the nature of arid Australia.

Book excerpt: This book introduces the Australian spider fauna and includes many species that are well known to Australian biologists, naturalists, gardeners and pest controllers. Spiders of Australia provides for the first time information on a vast spectrum of the Australian spider fauna and illustrates and describes over 150 species in some detail. Many other species are mentioned and discussed and a thorough summary of spider morphology, biology and classification is also provided. All representative families are described in some detail and the numbers of each family are listed on Australian and World levels. Most of the major genera of each family are described and representative species illustrated and described. Most of the spiders illustrated are photographed alive in their natural settings while approx. 30 species are represented by paintings of living specimens. The illustrations and descriptions make it easy for the layperson to identify many common spiders and provides also for the first time, an up to date reference list of hundreds of old and more recent scientific papers, books and other articles on Australian and related spider species. This list is organized into families and will prove to be an indispensable tool for serious workers on Arachnida. Much of the information provided for many of the species is new, based on the authors own field observations.The book is aimed for the scientist, naturalist, student and layperson both in Australia and overseas.

This book was released on 2010 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] Fire is a common disturbance in many ecosystems and an integral part of arid Australia. However, there are many gaps in the current knowledge of how the fauna and flora of the arid zone respond to fire. This is particularly true for invertebrates, including spiders, where there are several obstacles to successful biodiversity conservation. Besides lack of knowledge of the response of spiders to fire, there is also a considerable taxonomic impediment. That is, a majority of species are described long ago or not at all. I set out to improve our knowledge for the conservation of spiders in arid Australia by removing part of this taxonomic impediment and examining the long-term response of spiders to fire. To help remove the taxonomic impediment and facilitate my investigations of the postfire response of spiders, I revise the taxonomy and systematics of a genus of wolf spiders. The Australian wolf spider genus Hoggicosa Roewer, 1960 with the type species Hoggicosa errans (Hogg, 1905), is revised to include ten species. Hoggicosa is comprised of burrowing lycosids, several constructing doors from sand or debris, and are predominantly found in semi-arid to arid regions of Australia. Of nine previously described species, three are synonymised with Hoggicosa castanea (Hogg, 1905) comb. nov., and four new species are described. A phylogenetic analysis including nine Hoggicosa species, 11 lycosine species from Australia and four from overseas, with Arctosa cinerea Fabricius, 1777 as outgroup, supported the monophyly of Hoggicosa. Proposed synapomorphies for Hoggicosa are a larger distance between the epigynum anterior pockets compared to the width of the posterior transverse part in females, and a large number of specialised setae on the tip of the cymbium in males. The analysis found that an unusual sexual dimorphism for wolf spiders (females more colourful than males), evident in four species of Hoggicosa, has evolved multiple times. To examine the post-fire changes in assemblages of spiders I established a chronosequence study in spinifex habitat of central Western Australia. Ground-active spiders were pitfall-trapped over nine months in 27 sites representing experimental fires (0 and 0.5 years) and wildfires (3, 5, 8 and 20 years post-fire). ... Changes in abundance with post-fire age were significant for three of the five emergent groups. The fourth-corner analysis yielded more detailed results, but overall the two approaches are considered complementary. These studies make a substantial contribution of new knowledge to assist with the conservation of spiders in the arid zone of Australia. I have removed the taxonomic impediment for a charismatic and common genus of wolf spiders. In addition, I have examined in detail the post-fire response of an assemblage of spiders in spinifex habitat. The high degree of determinism in this assemblage and the strong correlation between post-fire changes in the vegetation and spiders is promising for land managers. It suggests that managers can directly influence the conservation of the spider fauna by actively managing fire effects on habitat structure and floristics. The development of a traits-based approach, which may contribute to predicting post-fire responses of spiders in other habitats, was only moderately successful. However, the development of such a mechanistic approach is novel and deserves further attention.
