Download or read book Reproduction biology in grey wolves Canis lupus in Belarus Common beliefs versus reality written by Vadim Sidorovich and published by CHATYRY CHVERCI. This book was released on 2019-08-01 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This scientific monograph gives a detailed information about reproduction biology in the grey wolf Canis lupus in Belarus. This topic includes the wolf breeding (mating and denning) behavior, fertility of the species and mortality of its pups. The initial material was not collected occasionally from wolf hunters and wolf pup searchers, but mainly gained by authors first-hand according to a well-set research design and long-term. By analyzing the gathered data, we became convinced that in the wolf reproduction biology there are more exceptions than rules. Therefore, the standard patterns of reproduction biology in wolves that are wide-spread in the published literature about the species we call as common beliefs that are given versus the wolf reality that we have found in Belarus. Concerning the non-standard features in the wolf reproduction biology, we revealed that multiple breeding in wolf pack is a common phenomenon, breeding of yearling females and wolf-dog hybridization were found to be irrespective the food base and strongly depending on the species population density i.e. they are reproduction regulations. Wolf pup mortality was investigated and the crucial role of deliberate predation of lynxes on wolf pups was revealed.
Download or read book The Wolves of Mount McKinley written by Adolph Murie and published by UBS Publishers' Distributors. This book was released on 1985 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the time of Lewis and Clark, wolves were abundant throughout North America from the Arctic regions to Mexico. But man declared war on this cunning and powerful animal when cattle replaced the buffalo on the western plains, reducing the wolf's range to those few areas in the Far North where economic necessity did not call for its extinction. Between 1939 and 1941, Adolph Murie, one of North America's greatest naturalists, made a field study of the relationship between wolves and Dall sheep in Mount McKinley National Park (since renamed Denali National Park) which has come to be respected as a classic work of natural history. In this study Murie not only described the life cycle of Alaskan wolves in greater detail than has ever been done, but he discovered a great deal about the entire ecological network of predator and prey. The issues surrounding the survival of the wolf and its prey are more important today than ever, and Murie helps us understand the careful balance that must be maintained to ensure that these magnificent animals prosper. Originally available only in government publications which are long out-of-print, this account of a much maligned animal is now available in its first popular edition.

Download or read book Climate change Unpacking the burden on food safety written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-03-01 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is causing unprecedented damage to our ecosystem. Increasing temperatures, ocean warming and acidification, severe droughts, wildfires, altered precipitation patterns, melting glaciers, rising sea levels and amplification of extreme weather events have direct implications for our food systems. While the impacts of such environmental factors on food security are well known, the effects on food safety receive less attention. The purpose of Climate change: Unpacking the burden on food safety is to identify and attempt to quantify some current and anticipated food safety issues that are associated with climate change. The food safety hazards considered in the publication are foodborne pathogens and parasites, harmful algal blooms, pesticides, mycotoxins and heavy metals with emphasis on methylmercury. There is also, a dedicated section on the benefits of forward-looking approaches such as horizon scanning and foresight, which will not only aid in anticipating future challenges in a shifting global food safety landscape, but also help build resilient food systems that can be continually updated as more knowledge is assimilated. By building a more widespread and better understanding of the consequences climate change has on food safety, it is hoped that this document will aid in fostering stronger international cooperation in making our food safer by reducing the global burden of these concerns.
Download or read book Arctic Social Indicators written by Joan Nymand Larsen and published by Nordic Council of Ministers. This book was released on 2015-02-18 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arctic Social Indicators II (ASI-II) is a follow-up activity to ASI-I (2010) and the first Arctic Human Development Report (AHDR, 2004). The objective of ASI (2010) was to develop a small set of Arctic specific social indicators that as a collective would help facilitate the tracking and monitoring of change in human development in the Arctic. ASI indicators were developed for six domains that are considered prominent aspects of human development in the Arctic by residents in the Arctic: Health and Population; Material Wellbeing; Education; Cultural Wellbeing; Contact with Nature; and Fate Control. The objective of the present volume of ASI is to present and discuss the findings of the work on measuring the set of recommended ASI indicators; to conduct a series of regional case studies to illustrate and test the strength and applicability of these indicators; to identify and describe data challenges for the Arctic region specifically in relation to these Arctic specific indicators and to draw conclusions about the ability of ASI to track changes in human development; and to formulate policy relevant conclusions for the long-term monitoring of Arctic human development. The core content of ASI-II is a set of five carefully selected case studies, which form the basis for drawing conclusions about the applicability of the ASI indicators and for formulating policy relevant conclusions. Case studies are performed for Sakha Republic (Yakutia); the West-Nordic Region; Northwest Territories; Inuit Regions of Alaska; and the Inuit World, with the Survey of Living Conditions in the Arctic (SLiCA) used to augment ASI. Findings on the state and changes in Arctic human development and wellbeing are presented. Based on our analysis and conclusions from the five case studies the framework for an ASI monitoring system is introduced. We argue that the long-term monitoring of human development in the Arctic would be greatly facilitated by the regular and frequent collection and reporting of relevant data, including those required for the proposed small set of ASI indicators.
Download or read book Ecology and Biogeography of High Altitude Insects written by M.S. Mani and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: In my book Introduction to High Altitude Entomology, published in 1962, I summa rized the results of eight years' studies, mainly on the Himalaya. I have since then had the opportunity of studying the collections of high altitude insects from the Alps, Carpathians, Caucasus, Urals, Alai-Pamirs, Tien Shan, Altai and other im portant mountains of the world in different museums and institutions in Europe. Through the courtesy and generosity of the Academy of Sciences of the Union of Soviet Socialist Republics, I was also able to personally collect insects and make valuable field observations on the Caucasus, the Alai-Pamirs, Ala-Tau and the Tien Shan mountains. Through comparative studies I have tried to synthesize the fundamental principles of high altitude entomology. I have described here the distinctive characters of the high altitude environment, the ecological specializations of the high altitude insects, their ecological inter relations and the outstanding peculiarities of their biogeography. I have also pre sented here an outline of the high altitude entomology of the principal mountains of the world, with brief accounts of their orogeny, geology and vegetation. This book differs from all other contributions in the field in its comparative ecological approach and in the fact that the main emphasis is throughout on the evolution of the high altitude ecosystem as an integral part of the orogeny. High mountains are, in all parts of the world, important and independent centres of origin and differ entiation of distinctive and highly specialized ecosystems and faunas.
