About 30 miles south-west of Land’s End is the low group of rocks and islands that form the Isles of Scilly. Mysterious, romantic and beautiful, they have long exercised the imagination of story tellers and historians.
A study of rare plants and their world in Britain. The author describes their discovery and the places they are found as well as looking at species which have died out completely, others which became naturalized long ago, and the discovery of new native plants in recent years. Conservation projects past and present are examined, and comments made on whether or not they have been successful.
The natural history of an ordinary English country parish was one of the first subjects that suggested themselves when the New Naturalist series was planned. This edition is exclusive to newnaturalists.com
This text is a history of the world's oldest global conservation body - the World Conservation Union, established in 1948 as a forum for governments, non-governmental organizations and individual conservationists. The author draws on unpublished archives to reveal the often turbulent story of the IUCN and its achievements in, and influence on, conservation and environmental policy worldwide - establishing national parks and protected areas and defending threatened species.
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.
"This dual biography takes on the daring task of examining how two women, who didn't feel like women, survived as a couple, raising an illegitimate child during a period when such arrangements were frowned upon, if even recognized. When they met in 1918, H.D. (born Hilda Doolittle in 1886), had already achieved recognition as an Imagist poet, engaged in a lesbian affair, was married to a shell-shocked adulterous poet, and was pregnant by another. She fell in love with Bryher (born Annie Winifred Ellerman in 1894), trapped both in a female body and in the shadow of her father, Sir John Ellerman, a wealthy shipping magnate. They felt a telepathic and electric connection, bonding over Greek poetry, geography, ancient history, and a shared bodily dysphoria. Bryher introduced H.D. to cinema, psychoanalysis, and politics, herself rescuing refugees from Nazis throughout the 1930s. Bryher engaged in legal strategies to protect H.D., marrying Kenneth Macpherson, who adopted H.D.'s child and collaborated with the couple in filmmaking, discovering his queerness. Both H.D. and Bryher were on vision quests, and their cerebral eroticism led them to otherworldly experiences. During World War II, they held séances in London. After "V-J Day" was announced, H.D. had a severe nervous breakdown, which Bryher, taking great pains, ensured she survived. As a love story born out of war and modernism, the book speaks to their struggles to escape binary gender, homophobic and white supremacist agendas, while celebrating their creative triumphs and courageous aspirations"--
Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.
Using a wealth of international case studies and photos, Ecotourism: An Introduction provides an accessible and comprehensive introduction to the key foundations, concepts and issues related to Ecotourism, the fasted growing segment of the global tourism industry. Among the topics covered are: * the foundations of ecotourism * tourism and ecotourism policy * the economics, marketing and management of ecotourism * the social and ecological impacts of tourism * ecotourism and development * the role of ethics in ecotourism The book includes case studies from Scotland, Austria, the USA, Canada, Mexico and Australia.
The last major synthesis of our knowledge of fish migration and the underlying transport and guidance phenomena, both physical and biological, was "Fish Migration" published 16 years ago by F.R. Harden Jones (1968). That synthesis was based largely upon what could be gleaned by classical fishery-biology techni.ques, such as tagging and recapture studies, commercial fishing statistics, and netting and trapping studies. Despite the fact that Harden Jones also provided, with a good deal of thought and speculation, a theoretical basis for studying the various aspects of fish migration and migratory orientation, progress in this field has been, with a few excepti.ons, piecemeal and more disjointed than might have been expected. Thus we welcomed the approach from the NATO Marine Sciences Programme Panel and the encouragement from F.R. Harden Jones to develop a proprosal for, and ultimately to organize, a NATO Advanced Research Institute (ARI) on mechanisms of fish migration. Substantial progress had been made with descriptive, analytical and predictive approaches to fish migration since the appearance of "Fish ~ligration." Both because of the progress and the often conflicting results of research, we felt that the time was again right and the effort justified to synthesize and to critically assess our knowledge. Our ultimate aim was to identify the gains and shortcomings and to develop testable hypotheses for the next decade or two.
