Download or read book Pilbara Seed Atlas and Field Guide written by Todd Erickson and published by CSIRO PUBLISHING. This book was released on 2016-04-01 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pilbara region in Australia’s arid northwest is rich in flora that is suited to extreme temperatures and boom and bust cycles of moisture availability. It is also a region important for its natural resources. In places where mining activities have finished and the land is under management for ecological restoration, there is increasing demand for information about native plant communities and the biology of their seeds. Pilbara Seed Atlas and Field Guide is the first book to combine plant identification with robust, scientific criteria for cost-effective seed-based rehabilitation. It describes 103 regional plant taxa and provides guidelines for effective collection, cleaning, storage and germination of their seeds. It addresses issues such as timing of collection, quality and viability of seed, and dormancy release, which are essential for successful restoration programs. With photographs to portray the subtle differences and unique features of each species’ biology, this book will be of great use to practitioners in the field, including environmental consultants, rehabilitation companies, commercial seed collectors and government authorities, as well as naturalists and people interested in growing the Pilbara’s remarkable plants.
Download or read book Vernal Pools in the Southwest Australian Floristic Region written by Renee E. Tuckett and published by . This book was released on 2010 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] Vernal pools (a form of temporary wetland) of the Southwest Australian Floristic Region (SWAFR) are rich in species and endemism. There are two types of vernal pool in the SWAFR, claypans and gnammas, each with their own specialist and cosmopolitan species. Both types of vernal pool are subject to a number of localised and global threats. This is the first detailed study on the flora of claypans and gnammas in the SWAFR bringing together both biogeography and seed biology to provide practitioners the knowledge to effectively conserve the plant species occurring in these ecosystems. Biogeographical surveying of gnammas throughout the SWAFR showed that gnammas have one of the highest levels of plant endemism for any ecosystem in the SWAFR. However, species richness was not correlated with any of the environmental or morphological parameters measured. Pockets of richness were identified and found to be scattered throughout the region. I show that the drivers of species richness for gnammas differ to those of the terrestrial flora of the SWAFR and to those of the claypans. The lack of correlations and absence of shared genera between gnammas and the flora from surrounding ecosystems suggest that gnammas species have originated via long-distance dispersal attributing to the random mosaic of pools with high species richness. Germination and dormancy of seeds from claypans and gnamma species is variable with seed from some species being dormant and those from others not. While non-dormant seeds were able to germinate over a range of temperatures, temperatures upon which germination was highest was species-specific. Seeds from some species, including members of the Hydatellaceae, an early divergent angiosperm, had a germination temperature preference of 5-10 °C, lower than that previously been recorded for Australian aquatic species. In fact, for aquatic plant species worldwide, temperature preferences for germination below 15 °C are uncommon. A light preference or requirement for germination was a significant variable for all species thus I conclude that maintaining the integrity of the soil crust may be an important first step for on-site conservation of vernal pool and gnamma species. A particular focus of the thesis is the Hydatellaceae, a group of tiny annual aquatic plants that have undergone recent taxonomic realignment to the base of the angiosperm phylogenetic tree. The Hydatellaceae are important for developing our understanding of the processes of evolution in early angiosperms. I observed a type of germination, whereby the embryo differentiates outside of the seed coat, that heretofore has not been reported and thus assign a new type of specialised morphophysiological dormancy to these primitive plants. Evolution of embryo types and desiccation tolerance is also discussed in light of presented results. Ex situ storage of seeds in facilities such as seed banks is a cost effective and efficient method of plant genome conservation. Seed storage theory predicts that as storage temperature and moisture content of seeds decrease (with some limitations) the longevity of orthodox (desiccation-tolerant) seeds can be extended...

Download or read book Species at Risk Research in Australia written by R.H. Groves and published by Springer. This book was released on 1982 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary progress has long been associated with the extinction of species. So why should we be concerned now, even when the number of species at risk is substantial, such as one tenth of the Australian flora? The reasons for concern are many stranded. Compassion is one strand. Remember the instructions to Noah: 'And you shall bring living creatures of every kind into the ark and keep them alive with you'. Guilt may be another strand, that our hunting, clearing, collecting, pollution, introduction of competitors and other human activities may have endangered species such as the Orange-bellied Parrot. Nostalgia for what was and concern for what might be also play a part; species at risk include some which are of immediate use, such as the whales, and many of potential use, whether drug plants in the forests of the Amazon or a wild relative of the soybean in Victoria. Aesthetic considerations are also involved, particularly where colourful birds or unusual flowers are threatened. We cherish diversity, as culturally desirable, and are delighted when supposedly extinct species such as the notornis and coelacanth - and maybe yet the thylacine - are rediscovered. The Loch Ness monster has already been blessed with a Latin binomial in anticipation! Diversity is also of ecological as well as of cultural value, contributing to the stability of ecosystems, as in the case of insects and birds which fertilize the flowers and disperse the seeds of plants.

Download or read book Understanding the Factors that Influence Seedling Establishment to Improve the Success of Threatened Species Translocations in the Mediterranean climate Region of Southwest Australia written by Christine Allen and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated] Translocations have become a common management tool across the globe to establish or augment populations of threatened plant species to reduce the risk of extinction. Translocations often involve germinating seed ex-situ and planting seedlings into a specified site. As the translocation process is relatively costly and there is often limited seed availability, it is important to maximise seedling survival to increase the chances of establishing a self-sustaining population. Manipulating abiotic and biotic variables at a translocation site is one strategy used to improve seedling survival and further understand the ecology of threatened species. Southwest Australia is one of 34 global biodiversity hotspots with a high proportion of threatened plant species. Consequently, translocations have been implemented in this region by the Department of Parks and Wildlife over the last 20 years with varied degrees of success. My research focused on the Acacia and Banksia genera to build on the knowledge gained through past translocations and tests some novel ideas to explore the questions: (1) Is it possible to manipulate microhabitat safe site variables and plant seedlings with particular characteristics that together improve their growth and survival in a Mediterranean-climate? (2) Do plant physiological responses and microhabitat measurements help to explain seedling survival and growth? (3) Can we use data on natural seedling establishment and physiological responses to guide conservation of threatened species in a drying climate? My thesis incorporates research from both natural and translocation settings at three spatial scales.
