What are plant galls and how are they caused? This book introduces the Australian native insects that induce galls on plants and the plant species that host them. It explores the ways the insects have adapted to living part of their lives in the confined spaces of galls, and describes the strategies employed by different insect groups to find a suitable site to induce a gall, obtain food, mate and escape the gall.Life in a Gall also looks at the predators, parasitoids, inquilines, kleptoparasites and micro-organisms that prey on gall-inducing insects and the ways the insects defend themselves from these enemies. It covers the problems gall-inducing insects can cause for agriculture, forestry and horticulture, and gives examples of several pest species. On the positive side, the book describes the essential services gall-inducing insects provide by pollinating figs, controlling invasive weeds and contributing to indigenous food.The final chapter provides tips for people who want to collect and study galls, and shows that answering many of the questions still surrounding gall-inducing insects is not restricted to professional scientists but can be achieved by diligent amateurs too.- E-bokEngelska, 2012

This important scientific volume comprehensively explores the biology and ecological status of manatees and dugongs in all of the geographic regions where they can be found today, from the Caribbean to Eastern Africa, from Arabia to the Amazon, and from Japan through the South Pacific to Australia.Many of these dwindling populations are situated in developing countries--locales that have previously received little attention in the scientific literature.In these areas, people occupying rivers or coastlines still capture sirenians for food and other uses (oil, bones for carving, leather). In addition, disruption, erosion, or complete loss of sirenian habitat occurs because of dredge and fill, coastal run-off, chemical pollution, and damage from boat propellers.Sirenian Conservation features contributions from an international group of scientists who are working to address the many challenges to manatee and dugong food supply, environment, reproduction, and survival. They share stories of programs that rescue, rehabilitate, release, and monitor these animals; offer reports on practical, replicable, and cost-effective management techniques; and summarize current research strategies.
