Introduces some of the plants and animals that make up the Arctic tundra food chain, including the arctic willow, lemming, polar bear, snowy owl, ermine, and arctic wolf.
Welcome to the arctic tundra! As you hike along the frozen ground of this cold, dry region, the tundra may seem quiet and empty. But it is full of life, in the spring when migrating lemmings munch on spring flowers, and even in the winter, when fur-coated wolves, foxes, and hares dart and prowl through the snow. Summer and winter in the tundra, the hunt is on to find food—and to avoid becoming someone else’s next meal. All living things are connected to one another in a food chain, from animal to animal, animal to plant, plant to insect, and insect to animal. What path will you take to follow the food chain through the tundra? Will you ... Zoom with a peregrine falcon as it aims for its prey? Chomp with a caribou grazing on grasses? Sneak up on a polar bear fishing for its dinner? Follow all three chains and many more on this who-eats-what adventure!
What are food chains like in different habitats? Who eats whom in forests? Why are decomposers so important? Investigate the curious world of life science. Find out for yourself about food chains and webs through activities that you can do at home. Learn about where all food chains and webs start. See which animals are at the top of a tundra food web. This book will show you the importance of investigating and understanding the world around you.
Earth's plants, animals, and other organisms live in a diverse array of ecosystems. The conditions in these places vary dramatically, ranging from steamy rain forests to arid deserts to the cold depths of the ocean. Ecosystems of the World explores these locations and the life within them. Learn how adaptation has made it possible for living things to thrive across the globe. Discover the connections between organisms that keep Earth's complex ecosystems healthy.

The Arctic is often portrayed as being isolated, but the reality is that the connectivity with the rest of the planet is huge, be it through weather patterns, global ocean circulation, and large-scale migration patterns to name but a few. There is a huge amount of public interest in the ‘changing Arctic’, especially in terms of the rapid changes taking place in ecosystems and exploitation of resources. There can be no doubt that the Arctic is at the forefront of the international environmental science agenda, both from a scientific aspect, and also from a policy/environmental management perspective. This book aims to stimulate a wide audience to think about the Arctic by highlighting the remarkable breadth of what it means to study its ecology. Arctic Ecology seeks to systematically introduce the diverse array of ecologies within the Arctic region. As the Arctic rapidly changes, understanding the fundamental ecology underpinning the Arctic is paramount to understanding the consequences of what such change will inevitably bring about. Arctic Ecology is designed to provide graduate students of environmental science, ecology and climate change with a source where Arctic ecology is addressed specifically, with issues due to climate change clearly discussed. It will also be of use to policy-makers, researchers and international agencies who are focusing on ecological issues and effects of global climate change in the Arctic. About the Editor David N. Thomas is Professor of Arctic Ecosystem Research in the Faculty of Biological and Environmental Sciences, University of Helsinki. Previously he spent 24 years in the School of Ocean Sciences, Bangor University, Wales. He studies marine systems, with a particular emphasis on sea ice and land-coast interactions in the Arctic and Southern Oceans as well as the Baltic Sea. He also edited a related book: Sea Ice, 3rd Edition (2017), which is also published by Wiley-Blackwell.
