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?
Australia and New Zealand are home to a remarkable and unique assemblage of flora and fauna. Sadly though, by virtue of their long isolation, and a naïve and vulnerable biota, both countries have suffered substantial losses to biodiversity since European contact. Bringing together the contributions of leading conservation biologists, Austral Ark presents the special features and historical context of Austral biota, and explains what is being conserved and why. The threatening processes occurring worldwide are discussed, along with the unique conservation problems faced at regional level. At the same time, the book highlights many examples of conservation success resulting from the innovative solutions that have been developed to safeguard native species and habitats in both New Zealand and Australia. Austral Ark fills an important gap regarding wildlife gains and declines, and how best to take conservation forward to keep this extraordinary area of the world thriving.
"Volumes 1 and 2 dealt solely with leafy liverworts. This volume [3] continues to deal with the leafy liverworts, which make up 85% of the New Zealand liverwort flora."--From jacket, v. 3.
This book focuses on explaining the distribution of sexual systems (simultaneous hermaphroditism, sequential hermaphroditism, environmental sex determination,dioecy, androdioecy, etc.) among taxa, which remains a major challenge in evolutionary biology. Although significant advances have been made for angiosperms, there is not yet a theory that predicts the sexual system for the majority of animal taxa, and other taxa of plants also remain poorly understood. The problem, particularly for animals, is that sexual systems can be very conservative, with whole phyla and classes being characterized by a single sexual system; for example essentially the whole phylum Platyhelminthes is simultaneously hermaphroditic, whereas the Insecta (Hexapoda) and the Tetrapoda among the vertebrates, are exclusively dioecious. Sex allocation theory on the other hand, suggests that sexual systems should be highly responsive to evolution, changing with population density, life span, patterns of resource availability, etc. The book provides an overview of the topic and then presents a series of chapters, each dealing with a taxon with substantial lability in sexual system in order to identify the factors associated with changes in sexual system in each case. By doing so, the authors reveal factors that have not been considered in formal theory but seem to have a major impact on transitions between sexual systems. This book appeals to a wide readership in fields from zoology and evolutionary biology to botany.
This publication is the result of over 15 years' research and technology development and presents New Zealand and its environments in a completely new way.
This book provides keys, descriptions and illustrations for about 850 species of liverworts and hornworts, in 148 genera and 47 families, of Colombia and Ecuador. The largest genera are Lejeunea (66 spp.), Plagiochila (65), Frullania (54), Radula (33), Metzgeria (33), Cololejeunea (32), Cheilolejeunea (30), Bazzania (26), Drepanolejeunea (25), Ceratolejeunea (18), Diplasiolejeunea (18), and Syzygiella (18). Species descriptions include brief morphological characterization and discussion with emphasis on characters for identification, world range as well as distribution and habitat in Colombia and Ecuador. Classes, orders, families and genera are also described and the main features for recognition of the genera are briefly discussed. The introduction includes chapters on history of exploration, diversity and endemism, and classification. A glossary, bibliography and index to scientific names are also provided.
Providing the first full, comprehensive list of officially classified threatened New Zealand plants--186 threatened and 6 extinct native vascular plants--this ready reference contains the distinguishing features of each plant, the specific threat it faces, and its current distribution, enabling the user to identify threatened vascular plants by providing clear, technical botanical descriptions, notes, and full-color visuals. This handy guide was designed not only as an essential tool in the fight against extinction but also as a stunning showcase of the spectacular flora of New Zealand.
