Book Description
'Living on the Edge' examines the function of the Sahel region of Africa as an important wintering area for long-distance migrant birds. It describes the challenges the birds have to cope with – climate change, of course, and rapid man-made habitat changes related to deforestation, irrigation and reclamation of wetlands. How have all these changes affected the birds, and have birds adapted to these changes? Can we explain the changing numbers of breeding birds in Europe by changes in the Sahel, or vice versa?

Book Description
Polyphagous pests are primarily agricultural pests that feed on economically important agricultural and horticultural crops of wide taxonomic diversity across the globe. They cause immense damage across different crop varieties owing to their generalist and voracious food habits. The advent of mono-crop culture in a huge area and the massive use of pesticides post green revolution have massively increased pest outbreaks all over the world. The Middle Eastern countries, African continent and even the Indian subcontinent is increasingly facing resurgences of polyphagus pests. This book compiles an inclusive account of polyphagous pests. It covers locusts, termites, aphids, whiteflies, mealybugs, scale insects, gram pod borer, fall armyworm, thrips, mites and rodents. The book discusses mode of spread, enormity of losses caused, mechanism of action, and also means to reduce the crop losses. It brings together a unique perspective for researchers to learn effective pest management practices across all crops. This book is a reference guide to researchers and also useful for academicians and students of entomology.

Book Description
This is the first exhaustive review of literature on marine insects, which are defined in this volume as those that spend at least part of their life in association with the marine environment. Not only are true insects, such as the Collembola and insect parasites of marine birds and mammals, considered, but also other kinds of intertidal air-breathing arthropods, notably spiders, scorpions, mites, centipedes and millipedes, which live and feed with, or even on, the insects of marine habitats. The chapters, written by leading authorities, are divided into two sections, the first treating primarily ecological aspects, the second dealing with major groups of insects in marine environments.

Book Description
First published in 2012, this catalogue presents fifty-six Etruscan, Greek, and Italic carved ambers from the Getty Museum's collection—the second largest body of this material in the United States and one of the most important in the world. The ambers date from about 650 to 300 BC. The catalogue offers full description of the pieces, including typology, style, chronology, condition, and iconography. Each piece is illustrated. The catalogue is preceded by a general introduction to ancient amber (which was also published in 2012 as a stand-alone print volume titled Amber and the Ancient World). Through exquisite visual examples and vivid classical texts, this book examines the myths and legends woven around amber—its employment in magic and medicine, its transport and carving, and its incorporation into jewelry, amulets, and other objects of prestige. This publication highlights a group of remarkable amber carvings at the J. Paul Getty Museum. This catalogue was first published in 2012 at museumcatalogues.getty.edu/amber/. The present online edition of this open-access publication was migrated in 2019 to www.getty.edu/publications/ambers/; it features zoomable, high-resolution photography; free PDF, EPUB, and Kindle/MOBI downloads of the book; and JPG downloads of the catalogue images.

Book Description
The general interest and attention paid to the use of the renewable natural resources of the world have increased greatly during the last decades. This is due to the environmental dilemma into which mankind has got itself by the total disregard of ecological facts and laws, the underprizing of natural resources and the overemphasis on economic develop ment, coupled with unimpeded rapid population growth and the preponderance of material istic consumption-oriented attitudes. The management and use of natural resources such as forests, grasslands, rivers and lakes were formerly considered purely in a financial context, whereas latterly, a consciousness of their social function and the indirect economic benefits which can be derived from them has developed. Thus, as regards these traditional resources, multi-use concepts comprising eco nomically oriented utilisation as well as recreational, educational and social use have be come widely accepted. Conservation of natural resources for sustainable consumptive as well as non-consumptive uses has been recognised as a key element for maintaining eco nomic development all over the world. Fortunately, the industrialised countries have started to apply this principle themselves and in their technical and financial aid to the developing Third World countries. This is manifest from policy documents such as the World Bank Policy on Development of Wild Lands, issued in 1987.
