Download or read book New Lepidium Brassicaceae from New Zealand written by Peter James De Lange and published by PenSoft Publishers LTD. This book was released on 2013 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vascular flora of New Zealand contains an estimated 2400 species of indigenous plant, of which a staggering 83% are endemic. Nevertheless, despite the 244 years of botanical exploration there are still many flowering plants left to formally describe from New Zealand. In this issue of PhytoKeys the diversity of the endemic Cook’s Scurvy grass (Lepidium oleraceum) is subjected to a modern taxonomic treatment, recognising in the process ten new endemic species, and accepting six others described by past workers. This issue includes detailed descriptions for all 16 Lepidium species and discusses their ecology, ethnobotany and conservation status. A dichotomous key to the naturalised and indigenous Lepidium of the New Zealand archipelago is also provided.
Download or read book Biogeography and Evolution in New Zealand written by Michael Heads and published by CRC Press. This book was released on 2016-10-04 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biogeography and Evolution in New Zealand provides the first in-depth treatment of the biogeography of New Zealand, a region that has been a place of long-enduring interest to ecologists, evolutionary scientists, geographers, geologists, and scientists in related disciplines. It serves as a key addition to the contemporary discussion on regionalization—how is New Zealand different from the rest of the world? With what other areas does it share its geology, history, and biota? Do new molecular phylogenies show that New Zealand may be seen as a biological ‘parallel universe’ within global evolution?

Download or read book Islands written by Peter Vitousek and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceanic islands represent a set of systems in which biological diversity varies as a consequence of remoteness or size, not environment; they are also generally simpler than continental ecosystems. Islands therefore provide an opportunity to determine the direct effects of biological diversity on ecosystem function. The volume addresses the components of biological diversity on islands and their patterns of variation; the modern threats to the maintenance of biological diversity on islands; the consequences of island biology and its modification by humanity regarding aspects of ecosystem function; the global implications of islands for conservation; and how islands can help one to understand the processes inducing changes throughout the world.

Download or read book Genetics and Genomics of the Brassicaceae written by Renate Schmidt and published by Springer Science & Business Media. This book was released on 2010-12-03 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Genetics and Genomics of the Brassicaceae provides a review of this important family (commonly termed the mustard family, or Cruciferae). The family contains several cultivated species, including radish, rocket, watercress, wasabi and horseradish, in addition to the vegetable and oil crops of the Brassica genus. There are numerous further species with great potential for exploitation in 21st century agriculture, particularly as sources of bioactive chemicals. These opportunities are reviewed, in the context of the Brassicaceae in agriculture. More detailed descriptions are provided of the genetics of the cultivated Brassica crops, including both the species producing most of the brassica vegetable crops (B. rapa and B. oleracea) and the principal species producing oilseed crops (B. napus and B. juncea). The Brassicaceae also include important “model” plant species. Most prominent is Arabidopsis thaliana, the first plant species to have its genome sequenced. Natural genetic variation is reviewed for A. thaliana, as are the genetics of the closely related A. lyrata and of the genus Capsella. Self incompatibility is widespread in the Brassicaceae, and this subject is reviewed. Interest arising from both the commercial value of crop species of the Brassicaceae and the importance of Arabidopsis thaliana as a model species, has led to the development of numerous resources to support research. These are reviewed, including germplasm and genomic library resources, and resources for reverse genetics, metabolomics, bioinformatics and transformation. Molecular studies of the genomes of species of the Brassicaceae revealed extensive genome duplication, indicative of multiple polyploidy events during evolution. In some species, such as Brassica napus, there is evidence of multiple rounds of polyploidy during its relatively recent evolution, thus the Brassicaceae represent an excellent model system for the study of the impacts of polyploidy and the subsequent process of diploidisation, whereby the genome stabilises. Sequence-level characterization of the genomes of Arabidopsis thaliana and Brassica rapa are presented, along with summaries of comparative studies conducted at both linkage map and sequence level, and analysis of the structural and functional evolution of resynthesised polyploids, along with a description of the phylogeny and karyotype evolution of the Brassicaceae. Finally, some perspectives of the editors are presented. These focus upon the Brassicaceae species as models for studying genome evolution following polyploidy, the impact of advances in genome sequencing technology, prospects for future transcriptome analysis and upcoming model systems.
Download or read book Rat Island written by William Stolzenburg and published by Bloomsbury Publishing USA. This book was released on 2011-06-21 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rat Island rises from the icy gray waters of the Bering Sea, a mass of volcanic rock covered with tundra, midway between Alaska and Siberia. Once a remote sanctuary for enormous flocks of seabirds, the island gained a new name when shipwrecked rats colonized, savaging the nesting birds by the thousands. Now, on this and hundreds of other remote islands around the world, a massive-and massively controversial-wildlife rescue mission is under way. Islands, making up just 3 percent of Earth's landmass, harbor more than half of its endangered species. These fragile ecosystems, home to unique species that evolved in peaceful isolation, have been catastrophically disrupted by mainland predators-rats, cats, goats, and pigs ferried by humans to islands around the globe. To save these endangered islanders, academic ecologists have teamed up with professional hunters and semiretired poachers in a radical act of conservation now bent on annihilating the invaders. Sharpshooters are sniping at goat herds from helicopters. Biological SWAT teams are blanketing mountainous isles with rat poison. Rat Island reveals a little-known and much-debated side of today's conservation movement, founded on a cruel-to-be-kind philosophy. Touring exotic locales with a ragtag group of environmental fighters, William Stolzenburg delivers both perilous adventure and intimate portraits of human, beast, hero, and villain. And amid manifold threats to life on Earth, he reveals a new reason to hope.
Download or read book Plant Evolutionary Developmental Biology written by Alessandro Minelli and published by Cambridge University Press. This book was released on 2018-03-01 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared to animals, plants have been largely neglected in evolutionary developmental biology. Mainstream research has focused on developmental genetics, while a rich body of knowledge in comparative morphology is still to be exploited. No integrated account is available. In this volume, Minelli fills this gap using the same approach he gave to animals, revisiting traditional concepts and providing an articulated analysis of genetic and molecular data. Topics covered include leaf complexity and the evolution of flower organs, handedness, branching patterns, flower symmetry and synorganization, and less conventional topics such as fractal patterns of plant organization. Also discussed is the hitherto neglected topic of the evolvability of temporal phenotypes like a plant's annual, biennial or perennial life cycle, flowering time and the timing of abscission of flower organs. This will be informative reading for anyone in the field of plant evo-devo, from students to lecturers and researchers.
Download or read book Conservation of Tropical Birds written by Navjot S. Sodhi and published by John Wiley & Sons. This book was released on 2011-02-23 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation of Tropical Birds has been written by four conservation biologists whose expertise spans all the tropical regions of the world. It is the first book to cover all the major issues in tropical bird conservation. Current problems faced by tropical bird conservationists are summarised and potential solutions outlined based on the results of case studies. Birds are key indicators of ecosystem health, and such a well-studied group of organisms, that they provide an excellent lens through which to examine global conservation problems caused by phenomena such as climate change, declines in ecosystem services, habitat loss, fires, overexploitation, and invasive species. Therefore, the book also provides an engaging synopsis of the general issues in conservation and the problems faced by other wildlife. This book serves as an important resource and companion to all people interested in observing and conserving birds in the tropics and elsewhere.

Download or read book Seeds of New Zealand Gymnosperms and Dicotyledons written by Colin James Webb and published by . This book was released on 2001 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Thsi guide provides, for the first time, an account of the seeds and other persistent parts of fruits for New Zealand plants. ... Because seeds survive long after most plant parts have deteriorated, the guide will assist in many sciences: in analysing diet from the gut, gizzard contents or faeces of mammals or birds, recreating past plant distributins from deposits in bogs or soils, and determining native food and criop plants at archaeological sites. And because seeds are relatively conservative structures in terms of their evolutionary diversification, it will also a wealth of information of use in plant identification and classification - a critical science for conservation of biodiversity."--Back cover.
Download or read book On the Ecology of Australia s Arid Zone written by Hans Lambers and published by Springer. This book was released on 2018-08-21 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will appeal to an international audience as well as be irresistible to local readers. Anyone working or with an interest in Australia’s arid zone should need ready access to this book. There is no equivalent publication out there at the moment, and this book has many authoritative chapters, richly illustrated with colourful material. The challenge of this book was to assemble current knowledge on particular topics and concepts, and principles relating to them. It is also forward-looking by identifying where there are gaps or inadequacies in knowledge, and where future research needs to be directed. Lead authors were encouraged to take such an approach; they had the opportunity to involve any author they considered appropriate. The final product shouldbe a fabulous resource, also for university courses, especially at MSc level.
