Timing of blaeberry growth, tree regeneration, land use, plant orientation The author noted when blaeberry buds on Scottish alpine land began growth in spring and compared this with climatic data. He mapped natural tree regeneration on Deeside and Donside. The author criticises invalid claims about land use in Scotland and Norway, and about the alleged effects of sporting estates in reducing land fertility. Signs of orientation by plants and animals are described.
The author documents hatch-dates of ptarmigan and red grouse in relation to blaeberry growth and climate. He collates field observations on golden plover, involving proportions of dark-plumaged summering birds, breeding success, population density within and amongst areas, and declines since the late 1970s. Another chapter reviews evidence on dotterel abundance. The last chapter presents counts of the spring numbers of birds on many moorland and alpine study areas.
This is a book that can be enjoyed by novices and experts alike, both a beautiful coffee-table book and an invaluable reference guide.
An up-to-date overview of Vermont's geological, natural, and land use histories, in the context of past, present, and future human interactions with the landscape
This 1977 book analyses and describes the wild flora and fauna of Britain and identifies important sites that exemplify this rich heritage.
This volume presents a completely new and very substantial body of information about the origin of agriculture and plant use in Africa. All the evidence is very recent and for the first time all this archaeobotanical evidence is brought together in one volume (at present the information is unpublished or published in many disparate journals, confer ence reports, monographs, site reports, etc. ). Early publications concerned with the origins of African plant domestication relied almost exclusively on inferences made from the modem distribution of the wild progenitors of African cultivars; there existed virtually no archaeobotanical data at that time. Even as recently as the early 1990s direct evidence for the transition to farming and the relative roles of indigenous versus Near Eastern crops was lacking for most of Africa. This volume changes that and presents a wide range of ex citing new evidence, including case studies from Nigeria, Burkina Faso, Ethiopia, Uganda, Egypt, and Sudan, which range in date from 8000 BP to the present day. The volume ad dresses topics such as the role of wild plant resources in hunter-gatherer and farming com munities, the origins of agriculture, the agricultural foundation of complex societies, long-distance trade, the exchange of foods and crops, and the human impact on local vege tation-all key issues of current research in archaeology, anthropology, agronomy, ecol ogy, and economic history.
