This book was released on 2003 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation. "In the present book for the first time in Bulgaria are included results from 25 years of counts in the most important wetlands in the country referring to the Mid-winter numbers of the waterbirds there." "This long-term survey is a part of the regular counts of Divers, Grebes, Pelicans, Cormorants, Swans, Geese, Ducks, Coots, Waders, and Gulls, which have taken place in Europe, North Africa and the Middle East since 1967." "The book consists of two main parts. In the first part are presented 45 of the most significant Bulgarian wetlands (lakes, swamps, reservoirs and other water bodies) along the Danube and Black Sea coasts and inside the country." "For each one of the wetlands there is a short characteristic description indicating the average and the maximum values for the wintering birds, the three most numerous species, the world threatened species and those exceeding the 1% Ramsar criteria." "In the second part of the book are presented 106 species of waterbirds with the dynamics of their numbers for the period 1977-2001 including graphics for most of the species." "The characteristic changes that have taken place in their wintering populations and the tendencies established by other authors for Europe are also indicated." "The book is a result of many years of effort by ornithologists - professional and non-professional, of major Bulgarian Scientific institutions, non-government organizations and state departments. It is illustrated with many black and white drawings by the famous Bulgarian artist Georgi Pchelarov. The book will be especially useful for those who are interested in birdwatching, wetland management and conservation."--Jacket.

Download or read book Gulls of Europe Asia and North America written by Klaus Malling Olsen and published by Bloomsbury Publishing. This book was released on 2010-09-30 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: This eagerly awaited guide offers the most comprehensive treatment ever published on the gulls of Europe, Asia and North America. A total of 43 species is treated, and every species is described in considerable detail, with a full description of each plumage and racial variation. Gulls are intelligent, versatile, opportunistic, and ecological generalists. As such, they exploit a variety of habitats, both coastal and inland, take a wide range of food, and are often extremely abundant. They are also great wanderers, with several American species regularly appearing in Western Europe and vice versa. As well as identification criteria, this book includes an up-to-date assessment of the range and status of every species, together with information on patterns of vagrancy. This important guide is published at a critical time in the development of dull taxonomy. The large, white-headed forms occurring in the region comprise a superspecies complex, with the precise relationships between the various components still under considerable debate. A thorough illustrative and textual treatment of the group is much needed, and this book provided the most complete overview of the complex. The text is complemented not only by superb colour paintings by Hans Larrson, but also by a large selection of colour photographs, sourced from some of the finest bird photographers in the world. This is the essential reference to a fascinating and endlessly challenging group of birds.

Download or read book Birds in Europe written by BirdLife International and published by . This book was released on 2004 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: New review of bird conservation compiled by Ian Burfield and Frans van Bommel In 1994 BirdLife International published the landmark Birds in Europe: their Conservation Status - the first ever review of the conservation status of all regularly occurring European birds. This book rapidly became a cornerstone of BirdLife's conservation work and is widely used by the European Commission, national governments and NGO's. Fully updated, Birds in Europe: Population Estimates, Trends and Conservation Status covers the European continent from Greenland in the west to the Urals in the east, and from Svalbard in the north to the Canary Islands in the south, including Balkan and Caucasian countries where political instability made data collection impossible in 1994. Setting a new standard for conservation data, Birds in Europe (1994) was highly praised for the depth and breadth of its research. Monitoring programmes established since then have provided an even higher accuracy and quality of data for Birds in Europe (2004). Full population data is included on all 526 species regularly occurring in Europe. Half a page is devoted to each species, including an illustration, distribution map, population and trends data, status information, and a concise summary of its status across Europe. What the reviewers said about Birds in Europe (1994): "This work can only be described as monumental" British Birds "Anyone travelling to a European country should use this book to find out what is really happening" British Birds "This professionally researched, excellently presented and yet affordable book provides a unique review of the conservation status of European birds" Biological Conservation "an astonishing tour de force" Ibis "an ornithological bible for any bookshelf..Bird Book of the Year 1995" Birdwatch "a veritable goldmine of information on breeding and wintering populations across the continent" Birdwatch "Should be compulsory reading for Europe's environment ministers" New Scientist "Any serious birder will find this fascinating reading" New Scientist "The baseline for the conservation of the birds of Europe" Birding World '...easily readable information has been crammed into a small space, with which it is possible to get a good general picture of the status of a species in Europe' - Alula. `An invaluable indicator of the health of Europe's birdlife, clearly showing where conservation efforts should be concentrated. The publishers should be congratulated.'Birdwatch`A fascinating browse... well-produced and not expensive, so everyone with a serious interest in the birds of Europe should own a copy.'Birding World`Genuinely continent-wide... a frightening amount of information is packed into each species account, but the layout is clear and you can cut to the chase quickly if you are in a hurry... Deserves a wide audience. Highly recommended.' British Birds

Book excerpt: 'Living on the Edge' examines the function of the Sahel region of Africa as an important wintering area for long-distance migrant birds. It describes the challenges the birds have to cope with – climate change, of course, and rapid man-made habitat changes related to deforestation, irrigation and reclamation of wetlands. How have all these changes affected the birds, and have birds adapted to these changes? Can we explain the changing numbers of breeding birds in Europe by changes in the Sahel, or vice versa?

Available in PDF, EPUB and Kindle. Book excerpt: Given the fundamental importance of biodiversity, we knowsurprisingly little about it. We are sure that it is disappearingfast, yet at present we cannot even measure progress (orotherwise) towards the 2010 target set by world leaders forslowing this loss. This BirdLife assessment examines what the bestknown group of living things, birds, can tell us about the stateof biodiversity, the pressures upon it and the solutions that arebeing, or should be, put in place. It is a synthesis of currentknowledge and provides a benchmark against which we can assess ourefforts to conserve biodiversity in the future.`Anexciting testimony to BirdLife's Intent and capacity to influencepolicy at the highest levels... gives a clear overview of howindividual observations contribute to the bigger picture...auseful digest of contemporary conservation science presented in aless technical way.

Download or read book Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments written by Elżbieta Kalisińska and published by Springer. This book was released on 2019-03-01 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.

Download or read book Public Health Significance of Urban Pests written by Xavier Bonnefoy and published by World Health Organization. This book was released on 2008 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second half of the 20th century and the beginning of the 21st century witnessed important changes in ecology, climate and human behaviour that favoured the development of urban pests. Most alarmingly, urban planners now face the dramatic expansion of urban sprawl, in which city suburbs are growing into the natural habitats of ticks, rodents and other pests. Also, many city managers now erroneously assume that pest-borne diseases are relics of the past. All these changes make timely a new analysis of the direct and indirect effects of present-day urban pests on health. Such an analysis should lead to the development of strategies to manage them and reduce the risk of exposure. To this end, WHO invited international experts in various fields - pests, pest-related diseases and pest management - to provide evidence on which to base policies. These experts identified the public health risk posed by various pests and appropriate measures to prevent and control them. This book presents their conclusions and formulates policy options for all levels of decision-making to manage pests and pest-related diseases in the future. [Ed.]
