Download or read book The Great Eagles written by Michael O'Neal Campbell and published by CRC Press. This book was released on 2022-05-19 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the current literature and knowledge on the evolution and ecology of all the birds named as eagles, with particular emphasis on the larger species. It also examines the past and current relations between eagles and people, including habitat change and conservation issues. Eagle ecologies and conservation are currently seriously impacted by human activities such as industrialization, urbanization, pollution, deforestation and hunting. Some eagle species have consequently experienced extreme population changes. There are, however, some positive developments. Eagles have a strong, historic bond with human civilization, due to their status as the world’s most charismatic birds. Conservation policies have also been successful in repopulating some ecosystems with breeding eagles. Therefore, despite the complexity of this relationship, there may yet be hope for this unique species group, frequently rated as the kings of birds, and symbolic of human power, ambition, royalty, nationality, and even concepts of God. It is hoped that this book will contribute to the further understanding of these unique and fantastic birds.

Download or read book Ecology and Economics of the Great Plains written by Daniel S. Licht and published by U of Nebraska Press. This book was released on 1997-01-01 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Great Plains were once characterized by vast expanses of grass, complex interdependence among species, and dynamic annual changes due to weather, waterways, and fire. It is now generally accepted that less than one percent of the original tallgrass prairie remains. Habitat fragmentation, the loss of natural predator-prey associations, changes in species composition, and various commercial practices continue to threaten grassland biodiversity. Recently scholars and conservationists have discussed opportunities for large-scale restoration projects in the Great Plains, but they have provided few details. Daniel Licht offers here a bold new approach to restoring and conserving the grassland ecosystem. In describing hypothetical reserves, he explains how they could help conserve grassland biodiversity, reduce federal expenditures on agriculture, increase recreational opportunities, and sustain rural economies outside the reserves.

Download or read book Migration Harvest and Population Dynamics of Mourning Doves Banded in the Central Management Unit 1967 77 written by and published by . This book was released on 1982 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: A banding program for mourning doves (Zenaida macroura) was conducted by the 14 Central Management Unit (CMU) States and the U.S. FIsh and Wildlife Service during 1967-74. Banding and recovery records, as well as data from annual call-count and harvest surveys, were subsequently analyzed by a subcommittee of the Central Migratory Shore and Upland Game Bird Technical Committee. This paper presents information on mourning dove habitat, hunting regulations, and harvest in the CMU; distribution and derviation of band recoveries in and from CMU; distribution of mourning dove harvest in Mexico and Central America; chronology of migration; survival and recovery rates; effects of hunting on CMU mourning dove populations; and indirect nationwide mourning dove population estimates.
