Flora y fauna vertebrada del Canal de Castilla
Author: Fernando Jubete TazoEcological Regions of North America
Author: Publisher:
ISBN:
Category : Biogeography
Languages : en
Pages : 92
Book Description
This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

Aquatic Plant Book
Author: Christopher D. K. CookPublisher:
ISBN:
Category : Nature
Languages : en
Pages : 244
Book Description
"The book is a comprehensive guide to the aquatic plants of the world. It describes and illustrates 407 genera; including all ferns and flowering plants that are likely to be found in or floating on permanent or semi-permanent, fresh or salt water anywhere in the world. Care has been taken to describe juvenile and vegetative features which are often ignored in floristic literature but are so important for the identification of aquatics particularly as many species have short-lived or insignificant flowers that are easily overlooked or some species rarely develop flowers at all. The identification keys are based, when possible, on easily seen vegetative features. This book is also a reference work: for each genus information on distribution (native and introduced ranges), like forms, ecology, pollination mechanisms, disseminules and their dispersal mechanisms, uses, economic importance, and references to the literature is given." "It is hoped that this book will be of use not only to botanists and zoologists but also to all people concerned with aquatic ecosystems (natural or man-made) whether they be managers, engineers, weed controllers or conservation officers. Gardeners and aquarists should also find much useful information."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc. All Rights Reserved
New trends for innovation in the Mediterranean animal production
Author: R. BouchePublisher: Springer Science & Business Media
ISBN: 908686726X
Category : Science
Languages : en
Pages : 329
Book Description
The Mediterranean area shows a great diversity of livestock systems, depending on local resources and traditions, but also on the networking space where informational resources are available for producers. During the last decades, a lot of innovations have been conceived or introduced in the Mediterranean area, allowing livestock systems to remain competitive. The book looks at two main issues: firstly, it gives an updated review on the main innovations that significantly changed the activities of livestock production in the Mediterranean area in the recent past. Secondly, the focus lies on the extent to which these innovations improve the efficiency, ensure the socio-cultural basis or reduce the environmental impact of livestock systems. One major finding is a new vision of innovating systems based on the distinction between regulated innovation (when aims are fixed) and innovative design (when aims are questioned). Innovations reported in the book are dealing with a set of concerns. They concern the production techniques, the work organization, the equipment and infrastructures, the collective features for selection, reproduction, feeding or sanitary devices. They also concern the local organization such as product labelling, new dynamics around local breeds, collective rules for supply basin or approaches of new products for new markets. More recently, some innovations focus on environmental impacts of livestock production, due to an increasing consciousness of those kinds of problems. In the final part of the book, a round table copes with a crucial question: are traditions in Mediterranean livestock activities to be considered an obstacle or a source of innovation? This book provides a set of updated information and knowledge useful for researchers, students, extension services and policy-makers in the field of animal science.
Fossil Horses of South America
Author: José Luis PradoPublisher: Springer
ISBN: 3319558773
Category : Science
Languages : en
Pages : 157
Book Description
This book provides an update on the phylogeny, systematics and ecology of horses in South America based on data provided over the past three decades. The contemporary South American mammalian communities were shaped by the emergence of the Isthmus of Panama and by the profound climatic oscillations during the Pleistocene. Horses were a conspicuous group of immigrant mammals from North America that arrived in South America during the Pleistocene. This group is represented by 2 genera, Hippidion and Equus, which include small species (Hippidion devillei, H. saldiasi, E. andium and E. insulatus) and large forms (Equus neogeus and H. principale). Both groups arrived in South America via 2 different routes. One model designed to explain this migration indicates that the small forms used the Andes corridor, while larger horses used the eastern route and arrived through some coastal areas. Molecular dating (ancient DNA) suggests that the South American horses separated from the North American taxa (caballines and the New World stilt-legged horse) after 3.6 - 3.2 Ma, consistent with the final formation of the Panamanian Isthmus. Recent studies of stable isotopes in these horses indicate an extensive range of 13C values cover closed woodlands to C4 grasslands. This plasticity agrees with the hypothesis that generalist species and open biome specialist species from North America indicate a positive migration through South America.
Coral Reefs of the Eastern Tropical Pacific
Author: Peter W. GlynnPublisher: Springer
ISBN: 9401774994
Category : Science
Languages : en
Pages : 666
Book Description
This book documents and examines the state of health of coral reefs in the eastern tropical Pacific region. It touches on the occurrence of coral reefs in the waters of surrounding countries, and it explores their biogeography, biodiversity and condition relative to the El Niño southern oscillation and human impacts. Additionally contained within is a field that presents information on many of the species presented in the preceding chapters.
The Lizards, Crocodiles, and Turtles of Honduras

ISBN: 9780674984165
Category : Crocodiles
Languages : en
Pages : 0
Book Description
Based on years of field work and the examination of thousands of museum specimens, The Lizards, Crocodiles, and Turtles of Honduras is the final installment of a series of volumes by James R. McCranie documenting the amphibians and reptiles of Honduras. Thoroughly illustrated by color photographs and maps of geographic distribution, the book describes in detail 86 species of Honduran lizards, crocodilians, and turtles. Identification keys in both English and Spanish allow the ready identification of all species, and discussions of conservation status review current threats to all species. The publication of this work represents the completion of the most comprehensive and detailed study of the amphibian and reptilian faunas of any country in Latin America.

Identity by Design
Author: Georgia Butina-WatsonPublisher: Routledge
ISBN: 1136396950
Category : Architecture
Languages : en
Pages : 299
Book Description
In a world of increasing globalisation, where one high street becomes interchangeable with the next, Identity by Design addresses the idea of place-making and the concept of identity, looking at how these things can be considered as an integral part of the design process. Structured around a series of case studies including Prague, Mexico, Malaysia and Boston, the authors discuss an array of design approaches to explain and define the complex interrelated concepts. The concluding sections of the book suggest ideas for practical application in future design processes. With full colour images throughout, this book takes the discussion of place-identity to the next level, and will be valuable reading for all architects, urban designers, planners and landscape architects.
