Book Description
This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel's, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly popular with naturalists, birders, and other outdoor enthusiasts.

Book Description
"The Iowa Breeding Bird Atlas"—the first comprehensive statewide survey of Iowa's breeding birds—provides a detailed record of the composition and distribution of the avifauna of the Hawkeye State. The atlas documents the presence of 199 species, 158 of which were confirmed breeding. This landmark volume will alert Iowans to the limited distribution of numerous species and serve as a guide to the management practices—such as forest and wetland management, set-aside programs, reduction in farm chemical use, and crop diversity—which could help insure that many future changes are positive ones. "The Iowa Breeding Bird Atlas" provides a welcome and much-needed baseline for future comparisons of changes in Iowa's birdlife and, by extension, the lives of all animals in the state.

Book Description
This edited volume documents the current nature conservation status of arable habitats in Europe. Arable farming systems have evolved in the European landscape over more than ten thousand years and now occupy nearly 30% of the European land area. They support species that have life cycles closely synchronised with traditional cereal growing, many of which have experienced massive declines throughout Europe. For example, in Britain, of the 100 plant species exhibiting the greatest declines in the latter half of the 20th century, 47 were typical of arable land. Despite this the habitat and many of the species associated with it remains unprotected across much of Europe. The 22 chapters cover a range of topics, including: · Regional accounts describing the impact of changing agricultural practices on the arable flora; · The results of research and surveillance projects on the soil organisms, bryophyte flora, invertebrate fauna and pollinators of arable habitats; · The potential for designing multifunctional and resilient agricultural landscapes; The use of ex situ conservation to aid the reintroduction of rare arable plants; · Case studies illustrating how changing agricultural practices have impacted on bird populations in Europe; · The roles of remote sensing in monitoring agricultural systems; · How agri-environment schemes can help restore the biodiversity in arable habitats; and · A look forward at ways to help ensure the future security of the species associated with arable habitats. It is clear that the biodiversity of arable land throughout Europe has undergone major changes, particularly during the second half of the 20th century, and that these changes are continuing into the 21st century. We need to develop a deeper appreciation of farmland wildlife and its integration into farming systems to ensure its future security in a world where value is increasingly expressed in terms of material profit. This book is particularly relevant to practitioners, policy-makers and managers working in the fields of nature conservation, agri-environment schemes and land management, and to researchers working in the fields of conservation biology, terrestrial ecology, nature conservation, applied ecology, biodiversity, agriculture, agricultural ethics and environmental studies.

Book Description
"Based on an analysis of 47 years (1967-2014) of Audubon Christmas Bird Counts (CBC), evidence for population changes and shifts in early winter (late December) ranges of nearly 150 species of birds in the Great Plains states is summarized, a region defined as including the Dakotas, Nebraska, Kansas, Oklahoma, and the Texas panhandle. The rationale for this study had its origins in Terry Root's 1988 Atlas of North American Wintering Birds. ... The present analysis includes all of the 40 annual CBC surveys from the 1967-8 to the 2006-7 counts, plus the results of the most recent 2013-14 CBC. The present summary quantitatively describes the early winter abundance for 147 of the most commonly encountered regional species, illustrating their temporal changes in geographic distributions and relative abundance between 1967 and 2014"--Publisher description.
