Tropical Forest Ecosystem Responses to Increasing Nutrient Availability
Deforestation and land use change have led to a strong reduction of tropical forest cover during the last decades. Climate change will amplify the pressure to the remaining refuges in the next years. In addition, tropical regions are facing increasing atmospheric inputs of nutrients, which will have unknown consequences for the structure and functioning of these systems, no matter if they are within protected areas or not. Even remote areas are expected to receive rising amounts of nutrients. The effects of higher rates of atmospheric nutrient deposition on the biological diversity and ecosystem functioning of tropical ecosystems are poorly understood and our knowledge of nutrient fluxes and...
Tropical Montane Cloud Forests
Until relatively recently the valuable tropical montane cloud forests (hereaf ter usually referred to as TMCFs) of the world had scarcely come under the assaults experienced by the downslope montane and lowland forests. TMCFs are not hospitable environments for human occupation, and their remoteness (except in places near Andean high mountain settlements and in the Ethiopian Highlands) and difficult terrain have given them de facto protection. The ad jacent upper montane rain forests have indeed been under assault for timber, fuelwood, and for conversion to grazing and agriculture for many decades, even centuries in the Andes, but true cloud forest has only come under ex ploitation as these ...
The Practical Science of Planting Trees
"Since 1943, the International Society of Arboriculture has been publishing books that have documented changes in tree planting practices over the decades. This comprehensive volume is an up-to-date synthesis of the research devoted to planting urban trees. Anyone interested in planting trees - arborists, landscape professionals, students, researchers, and avid gardeners - will find this book to be an invaluable resource with an extensive reference list of scientific literature. Designed to help readers understand and implement the appropriate practices vital to planting a tree, it offers guidance to improve success and establish healthy trees that will last a lifetime."--Pub. desc.
The Role of Microbial Communities in Tropical Ecosystems
Tropical ecosystems are different in important ways from those of temperate regions. They are a major reservoir of plant and animal biodiversity and play important roles in global climate regulation and biogeochemical cycling. They are also under great threat due to the conversion of tropical ecosystems to other uses. Thus, in the context of global change, it is crucial to understand how environmental factors, biogeographic patterns, and land use changes interact to influence the structure and function of microbial communities in these ecosystems. The contributions to this Research Topic showcase the current knowledge regarding microbial ecology in tropical ecosystems, identify many challenges and questions that remain to be addressed and open up new horizons in our understanding of the environmental and anthropological factors controlling microbial communities in these important ecosystems.
Birthday Letters
Ted Hughes's Birthday Letters are addressed, with just two exceptions, to Sylvia Plath, the American poet to whom he was married. They were written over a period of more than twenty-five years, the first a few years after her suicide in 1963, and represent Ted Hughes's only account of his relationship with Plath and of the psychological drama that led both to the writing of her greatest poems and to her death. The book became an instant bestseller on its publication in 1998 and won the Forward Prize for Poetry in the same year. 'To read [ Birthday Letters] is to experience the psychic equivalent of "the bends". It takes you down to levels of pressure where the undertruths of sadness and endurance leave you gasping.' Seamus Heaney 'Even if it were possible to set aside its biographical value . . . its linguistic, technical and imaginative feats would guarantee its future. Hughes is one of the most important poets of the century and this is his greatest book.' Andrew Motion
The Case for Marriage
A groundbreaking look at marriage, one of the most basic and universal of all human institutions, which reveals the emotional, physical, economic, and sexual benefits that marriage brings to individuals and society as a whole. The Case for Marriage is a critically important intervention in the national debate about the future of family. Based on the authoritative research of family sociologist Linda J. Waite, journalist Maggie Gallagher, and a number of other scholars, this book’s findings dramatically contradict the anti-marriage myths that have become the common sense of most Americans. Today a broad consensus holds that marriage is a bad deal for women, that divorce is better for childr...
