Download Biological Invasions And Its Management In China: Volume 1

The book discusses invasive-species problems in agriculture, forests and aquatic ecosystems, highlighting the invasive mechanisms and management of the selected invasive species. Biological invasion has become a serious global ecological and economic problem that deserves particular attention from both government officials and scientists. This volume focuses on three key scientific areas: 1) population establishment and spreading mechanisms of the selected invasive species; 2) ecology adaptation, population growth, expansion and evolution of invasive species; and 3) impact of bio-invasion on the ecosystem structure and function at community and ecosystem levels. The presented research will result in techniques for better management of invasive species.

Five species of owl currently live in Britain–the Tawny, Barn, Little, Long-eared and Short-eared Owls–and each of them, as well as their relatives abroad, are introduced here in detail alongside top quality color photographs and fascinating behavioral images, which will delight and inform the whole family.

The book begins with a look at owls in general then examines the five British species in more detail. It discusses their evolutionary history and distribution around the world. Their anatomy and adaptations are examined, as well as their natural behaviors including hunting, nesting and mating practices. Next, we are introduced to their life cycles, beginning as eggs, moving onto fledging and independence, migration, and finally death.
