Book excerpt: The book provides a comprehensive overview of current knowledge about "wattles", a large clade of over 1000 species of trees and shrubs in the genus Acacia, most of which are native to Australia. It examines the biology, ecology, evolution, and biogeography of wattles in their native ranges, including the evolutionary forces that have driven past speciation and adaptation to diverse environments, the conservation status, uses and human perceptions of these species. It considers the different histories of the introductions and proliferation of wattles as alien species in different parts of the world since c. 1850 (the Anthropocene), situated within relevant political, socio-economic and scientific contexts, together with an analysis of how awareness of their impacts as invasive species has changed over time. Differences in the dynamics and trends associated with the introduction, naturalization and invasion of wattles in different parts of the world are reviewed. The book also synthesizes the global distribution of wattles using diverse data sources, alongside trends, patterns and projections of global uses of wattles. It discusses the genetics, biotic interactions, and ecological, economic and social impacts of invasive wattles. This book is aimed at academics and students in the field of ecology, and at managers of natural and anthropic ecosystems, policy-makers and regulators, and the general public interested in biology and environmental science.

Download or read book Evolution of Ecological and Behavioural Diversity written by Bernard J. Crespi and published by Csi. This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a novel, 'model clades' approach to the study of biodiversification, explicitly integrating behaviour, ecology, taxonomy, phylogenetics, and evolution. A single lineage of over 250 species (30 genera) of phytophagous thrips that has radiated on Australian Acacia is considered. Nine genera are newly described. The book explores causes and consequences of behavioural-ecological diversification with special emphasis on the evolution of social behaviour, host-plant use and exploitative behaviours. Ecological pressures of the arid and unpredictable Australian climate have selected for diverse means of creating, usurping, and co-opting domiciles. Such pressure has generated a positive feedback loop - adoption and modification of new host-plants by some thrips species creates further niches for additional ones. These thrips exhibit remarkable morphological, behavioural and ecological variation. They can be considered as a microcosm for understanding processes that generate biodiversity among all phytophagous insects, and indeed among all animals.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The mid-west of Western Australia is a hotspot for plant species biodiversity, with many rare or short range endemic species. It is also heavily impacted by mining activities, which combined make conservation a priority. This thesis aims to assess the potential of high-throughput sequencing of chloroplast genomes to underpin the conservation genetics of the highly diverse and speciose genus Acacia (Fabaceae). This thesis focuses firstly on establishing a fully sequenced chloroplast genome for the Acacia genus, which also represents the first fully sequenced chloroplast genome of the Mimosoideae subfamily. The genome was compared to previously sequenced Fabaceae chloroplast genomes, all of which occur in the Papilionoideae subfamily and display significant rearrangements relative to Acacia. The key finding of these comparisons was the highly divergent nature of the A. ligulata clpP1 gene, which is extremely unusual in such a highly conserved gene. Using the A. ligulata genome as a reference, chloroplast genomes from an additional 64 Acacia species were sequenced and assembled. These genomes were used in a phylogenetic analysis of the genus, and the integration of these genome sequences with previously sequenced small amplicon sequences from throughout the Acacia genus was investigated. The results of this study suggested that the integration of these vastly different sized sequence types has the ability to significantly improve poorly supported phylogenies, particularly when utilising a whole chloroplast genome phylogeny as a constraint upon the shorter sequences. Further investigation of the Acacia clpP1 gene was performed using the full complement of Acacia chloroplast genome sequences. This study found that divergence in the gene was present throughout the genus with four clades in particular exhibiting extreme divergence, indicated by mutations in the ClpP1 catalytic site. Additionally, two clpP1 pseudogenes (one plastid and one nuclear) were identified in two different Acacia clades. Sequencing of the A. ligulata transcriptome ruled out the possibility of a functional nuclear clpP1 gene in this species, suggesting that despite its unusual sequence, the divergent plastid clpP1 gene is likely to be functional. Finally, this thesis tested whether the whole chloroplast genome was better able to distinguish between species than traditional DNA barcoding loci. The results of this study indicated that the whole chloroplast genome provided a better means of sequence based identification than the matK and rbcL barcodes, with 19 out of 26 currently recognised taxa distinguished using the chloroplast genome sequences compared to 14 and 8 taxa distinguished using matK and rbcL, respectively. This thesis has significantly increased our knowledge of Acacia chloroplast genome structure and content, provides a reference for further chloroplast genetics research in the Acacia genus, solidifies the backbone of the Acacia phylogeny, and takes a first step towards whole chloroplast genome DNA barcoding in Acacia, all of which informs our conservation of Acacia species.
Download or read book Edible Wattle Seeds of Southern Australia written by BR Maslin and published by CSIRO PUBLISHING. This book was released on 1998-01-01 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book identifies 47 Acacia species which have potential for cultivation in the southern semi-arid region of Australia as a source of seed for human consumption. Eighteen species are regarded as having the greatest potential. Botanical profiles are provided for these species, together with information on the natural distribution, ecology, phenology, growth characteristics and seed attributes. Two species, Acacia victoriae and Acacia murrayana, appear particularly promising as the seeds of both these have good nutritional characteristics and were commonly used as food by Aborigines. Acacia victoriae is currently the most important wattle used in the Australian bushfood industry. This book is a useful reference for the bush food industry.

Available in PDF, EPUB and Kindle. Book excerpt: This book is about phylogenetic diversity as an approach to reduce biodiversity losses in this period of mass extinction. Chapters in the first section deal with questions such as the way we value phylogenetic diversity among other criteria for biodiversity conservation; the choice of measures; the loss of phylogenetic diversity with extinction; the importance of organisms that are deeply branched in the tree of life, and the role of relict species. The second section is composed by contributions exploring methodological aspects, such as how to deal with abundance, sampling effort, or conflicting trees in analysis of phylogenetic diversity. The last section is devoted to applications, showing how phylogenetic diversity can be integrated in systematic conservation planning, in EDGE and HEDGE evaluations. This wide coverage makes the book a reference for academics, policy makers and stakeholders dealing with biodiversity conservation.

Available in PDF, EPUB and Kindle. Book excerpt: Nearly 700 species of plants may become extinct by the year 2000. Faced with this overwhelming prospect, plant conservationists must take advantage of every technique available. This unique work summarizes our current knowledge of the genetics and population biology of rare plants, and integrates it with practical conservation recommendations. It features discussions on the distribution and significance of genetic variation, management and evaluation of rare plant germplasm, and conservation strategies for genetic diversity. Case studies focusing on specific problems offer important insights for today's challenges in rare plant conservation.
