Available in PDF, EPUB and Kindle. Book excerpt: After years of decline, resulting in the extinction of the sand lizard Lacerta agilis in Wales, the species has now been returned to several dune system sites which also contain the viviparous lizard Zootoca vivipara. As dune system habitats are becoming an increasingly important habitat type in the UK for L. agilis, providing a relatively safe haven for these and Z. vivipara populations from anthropogenic change, it is time to ensure the long-term survival of these populations. In this study, environmentally advantageous conditions for detection of both species were established for three dune system sites in North-West Wales. Surface temperature, UV, cloud cover and wind speed were identified as being the most influential detection parameters, with cloud cover and wind speed noted as having a negative influence on detection. Furthermore, favoured habitat was identified and 'suitable habitat' modelled for both species. Across the research sites both species were found to utilise habitats of a similar composition with reintroduced L. agilis favouring specific habitat features such as basking direction and degree of angle of their basking position. Habitat and site utilisation models indicate that for highly mobile dune systems L. agilis dispersal across a site is not of concern. For static or eroding dune systems, large, connected areas of favoured habitats are absent. In this situation, L. agilis dispersal (from introduction locations) is limited. Mean yearly L. agilis dispersal distances of 19.64 m - 28 m represents an approximate trend across the three research sites. The physical presence of L. agilis alone, however, does not constitute a successful reintroduction. Genetic diversity of the reintroduced populations was observed to be lower than those calculated in naturally occurring British populations. This is a matter of conservation concern, with a number of targeted mitigatory measures proposed to improve the genetic integrity, reducing the chance of population extinction(s). Mean time to extinction estimates indicate that for populations on highly mobile dune systems population survival times of between 11.4 yrs and 63.1 yrs could be expected. This is reduced for static or eroding dune system sites. The implications of these findings for the conservation of L. agilis and Z. vivipara are discussed in the context of current challenges and future management requirements. It is hoped that this thesis will help guide the future development of the reintroduction program, and in addition, provide a sound scientific basis for the future management of reintroduction sites and species monitoring.
Download or read book The Status and Distribution of Reptiles and Amphibians of the Mediterranean Basin written by Neil Cox and published by IUCN. This book was released on 2006 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mediterranean-rim countries hold around 400 million people and 135 million of them live on the coast. A steady migration towards coastal areas, specifically in the south and east of the Mediterranean, is causing pressure on the coastal environment and, more importantly, on its biodiversity. In this second Mediterranean regional assessment, all the reptile and amphibian species existing within the region of study have been evaluated for their global conservation status. This assessment aims to assist in regional planning and to help identify internationally important sites for biodiversity. Like the first in the series, it also hopes to encourage development of a network of regional experts to enable future assessments and the continued updating of the baseline dataset.

Available in PDF, EPUB and Kindle. Book excerpt: • • • John Harper • • • Nature conservation has changed from an idealistic philosophy to a serious technology. Ecology, the science that underpins the technol ogy of conservation, is still too immature to provide all the wisdom that it must. It is arguable that the desire to conserve nature will in itself force the discipline of ecology to identify fundamental prob lems in its scientific goals and methods. In return, ecologists may be able to offer some insights that make conservation more practicable (Harper 1987). The idea that nature (species or communities) is worth preserv ing rests on several fundamental arguments, particularly the argu ment of nostalgia and the argument of human benefit and need. Nostalgia, of course, is a powerful emotion. With some notable ex ceptions, there is usually a feeling of dismay at a change in the sta tus quo, whether it be the loss of a place in the country for walking or rambling, the loss of a painting or architectural monument, or that one will never again have the chance to see a particular species of bird or plant.

Available in PDF, EPUB and Kindle. Book excerpt: This book is written to serve as a general reference for biologists and resource managers with relatively little statistical training. It focuses on both basic concepts and practical applications to provide professionals with the tools needed to assess monitoring methods that can detect trends in populations. It combines classical finite population sampling designs with population enumeration procedures in a unified approach for obtaining abundance estimates for species of interest. The statistical information is presented in practical, easy-to-understand terminology. - Presented in practical, easy-to-understand terminology - Serves as a general reference for biologists and resource managers - Provides the tools needed to detect trends in populations - Introduces a unified approach for obtaining abundance estimates

Download or read book Biodiversity of Angola written by Brian J. Huntley and published by Springer. This book was released on 2019-02-20 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access multi-authored book presents a 'state of the science' synthesis of knowledge on the biodiversity of Angola, based on sources in peer-reviewed journals, in books and where appropriate, unpublished official reports. The book identifies Angola as one of the most biologically diverse countries in Africa, but notes that its fauna, flora, habitats and the processes that drive the dynamics of its ecosystems are still very poorly researched and documented. This 'state of the science' synthesis is for the use of all students of Angola's biodiversity, and for those responsible for the planning, development and sustainable management of the country's living resources. The volume brings together the results of expeditions and research undertaken in Angola since the late eighteenth century, with emphasis on work conducted in the four decades since Angola's independence in 1975. The individual chapters have been written by leaders in their fields, and reviewed by peers familiar with the region.
