This is the first book  to describe the results from a British scheme to monitor butterflies  during this period of change. The Monitoring Scheme, initiated in 1976  by the senior author is based on frequent counts at some 90 sites  throughout Britain. The combined efforts of both amateurs and  professionals have thus produced a dataset with no equivalent  elsewhere in the world. The book therefore provides a unique  perspective on trends in numbers, extinction and foundation of  populations; flight periods, local distributions, migration and other  aspects of population ecology. Practical problems encountered during  the conservation of butterflies of individual sites are outlined. The  relevance of this monitoring for an understanding of the effects of  the weather - climatic warming - is described.\n            \n            \u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9780412402203\"\u003e\u003ch3\u003eThe British Butterfly Monitoring Scheme\u003c\/h3\u003e\u003c\/div\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9780412634604\"\u003e\u003ch3\u003eThe British Butterfly Monitoring Scheme\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Hardcover - 9780412402203","offer_id":39414393929821,"sku":"9780412402203","price":160.49,"currency_code":"EUR","in_stock":true},{"title":"Softcover - 9780412634604","offer_id":39414392356957,"sku":"9780412634604","price":171.19,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/3b061059-4746-4b23-9d36-4db53c6d0027.jpg?v=1765861469","url":"https:\/\/shop.autorenwelt.de\/products\/monitoring-butterflies-for-ecology-and-conservation-the-british-butterfly-monitoring-scheme-von-e-pollard-t-j-yates","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
