Available in PDF, EPUB and Kindle. Book excerpt: Periodic comprehensive overviews of the status of the diverse organisms that make up wildlife are essential to determining trends, threats and future prospects. Just over 25 years ago, leading authorities on different kinds of wildlife came together to prepare an assessment of their status of a wide range of organisms in Great Britain and Ireland in The Changing Flora and Fauna of Britain, also edited by Professor David L. Hawksworth CBE. Now, in The Changing Wildlife of Great Britain and Ireland, he has gathered together some of the original and also new contributors to review changes since that time and look to the future. Contributions range from viruses, diatoms, fungi, lichens, mites and nematodes; through butterflies, dragonflies, flies and slugs; to flowering plants, ferns, mammals, birds and fish. The state of knowledge in different groups is assessed, and the effectiveness of statutory and other measures taken to safeguard wildlife considered. The picture is far from bleak, ameliorating sulphur dioxide levels have benefited sensitive lichens and mosses in a dramatic way, water quality improvement has been beneficial, there have been few certain extinctions and rediscoveries of species thought to have been lost. Biodiversity Action Plans have also benefited targeted species, but habitat restoration and management for some is not always good for others. But there are worrying trends in declining populations, with an increasing number being regarded as threatened or endangered, especially in agricultural areas, and where woodland management has changed, particular threats from introduced species, and concern over the effects of climate change. Some of the smaller organisms remain poorly known, a situation unlikely to change as expertise in many is scant or being lost. This stock-check and look to the future will be a key source book to conservationists, naturalists, and professional biologists for many years to come.
Download or read book Leeches Lice and Lampreys written by Graham C. Kearn and published by Springer Science & Business Media. This book was released on 2007-11-05 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many different kinds of animals have adopted a parasitic life style on the skin and gills of marine and freshwater fishes, including protozoans, flatworms, leeches, a range of crustaceans and even some vertebrates (lampreys). There is a parasitic barnacle, described first in the 19th century by Charles Darwin, fish lice that change sex and bivalve molluscs parasitic only when young. This book explores for the first time in one volume, the remarkable biology of these little known and frequently bizarre animals. The following closely interwoven themes are considered for each group of parasites: how they find their hosts, how they attach, feed and reproduce, the damage they inflict and how the host’s immune system retaliates. Based on the British fauna, but extending where appropriate to examples from North America, Australia and elsewhere, the book is essential reading, not just for the professional parasitologist, but also for anyone interested in fishes and in this neglected field of British natural history. With the enquiring naturalist in mind, terms and concepts are explained as they arise, backed up by a glossary, and the text is liberally illustrated. An introductory chapter on fish biology sets the scene and common fish names are used throughout, as well as scientific names.
Download or read book The Atlas of Breeding Birds in Britain and Ireland written by J.T.R. Sharrock and published by A&C Black. This book was released on 2010-12-30 with total page 928 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atlas plots the results of the survey organised by the BTO and the IWC during the years 1968-72. Over 250 maps show the distribution of 218 species. This companion volume to The Atlas of Wintering Birds in Britain and Ireland is derived from yearly surveys of breeding birds in Britain and Ireland during 1968-72, organised by the British Trust for Ornithology and the Irish Wildbird Conservancy. Each of the 3,862 10-km squares of Britain and Ireland was visited during the five years and the resulting records (over 285,000) are summarised in the maps. The full-page maps plot the known distribution of all but 11 of the 229 breeding species located during the survey period. Each map has an accompanying text which describes the species' habitat, the problems involved in proving breeding, the historical background to the species' range and any changes in its numbers. The probable reasons for these changes are discussed and an attempt made to assess the total number of birds for each species. Jacket design by Robert Gillmor.

Available in PDF, EPUB and Kindle. Book excerpt: This volume of the Handbook of Zoology summarizes "small" groups of animals across the animal kingdom. Dicyemida and Orthonectida are enigmatic parasites, formerly united as "Mesozoa" and their position among the multicellular animals is still not known with certainty. Placozoa are small, flat marine animals which provide important information on metazoan evolution. Comb jellies (Ctenophora) are esthetically fascinating animals which cause considerable discussion about their phylogenetic position. Seisonida are closely related to rotifers and acanthocephalans. Cycliophora were discovered and described as one of the last higher taxa and surprise by their complex life cycle. Kamptozoa (= Entoprocta) are small sessile animals in the sea and sometimes also in freshwater. Arrow worms (Chaetognatha) play an important role as predators in the plankton, but they also include benthic forms. Pterobranchia and acorn worms (Enteropneusta) belong to the deuterostomia and are related to echinoderms. In particular enteropneusts play an important role in understanding deuterostome evolution. These chapters provide up to date reviews of these exiting groups with reference to the important literature and therefore serves as an important source of information.

Download or read book Animals under logs and stones written by C. Philip Wheater and published by Pelagic Publishing Ltd. This book was released on 2023-07-11 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: Logs, stones and the like provide an interesting interface between the damp depths of the soil and the drier open ground surface, offering refuges for a fascinating array of animals. The communities of organisms that live beneath them are little noticed and even less studied, yet the potential for ecological work here is great. Some of the animals are relatively large and frequently not difficult to find. They exhibit a wide range of lifestyles – from slow slugs or snails to very fast centipedes, from generalist to specialist feeders and from herbivores to carnivores. With chapters covering the cryptosphere environment, species groups, identification, guidelines and ideas for further research, this much-expanded and updated new edition also includes extensive, easy-to-use, comprehensively illustrated keys. Ground-surface debris can be found almost anywhere, often presenting highly accessible microhabitats for study and bringing immediate rewards to the curious: here is the ideal tool to unlock these worlds.

Download or read book Guide to British Freshwater Macroinvertebrates for Biotic Assessment written by and published by . This book was released on 2011 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides straightforward guides to the identification of macroinvertebrate families included in biotic assessment in the UK, covering flatworms, annelids, molluscs, larger crustaceans, arachnids and all aquatic orders of insects. By making extensive use of appropriate methods for different groups, including dichotomous keys, pictorial guides and tables, along with copious line drawing illustrations and general tips on identification, it allows rapid and confident identification of the major groups of British freshwater invertebrates. It has been extensively tested, and illustrations are designed to show both the appearance of whole animals and, where appropriate, key identification features. For each group, a brief indication of typical habitat is given, to further facilitate identification. An extensive list of keys and guides for further identification is also provided.
Download or read book Annelida written by Greg W. Rouse and published by Oxford University Press. This book was released on 2022-01-14 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annelids (the segmented worms) exist in a remarkably diverse range of mostly marine but also freshwater and terrestrial habitats, varying greatly in size and form. This text provides. This text begins with an introduction to the phylum and an outline of annelid taxonomy. The book describes their collection and the methods to ensure their optimal preservation, and provides an overview of anatomy with its relevant terminology. It includes the latest molecular phylogenomic evidence and is organised based on a new, robust phylogenetic hypothesis. It looks at groups which include Clitellata (comprising more than a third of total annelid diversity), Sipuncula, and Thalassematidae (formerly Echiura). It reflects the enormous amount of research on these organisms that has burgeoned since the millennium, principally due to their use as model organisms to address wider and more general evolutionary and ecological questions.
