The past thirty years have seen a renewed interest in this now-extinct biome, sometimes referred to as "tundra-steppe" (steppe-tundra in North American sources). While many questions remain, converging evidence from many new terrestrial records and proxies coupled with better understanding of ...

The Arctic tundra is located within the Arctic Circle and is identifiable by a lack of trees. A low rainfall of six to ten inches per year (including snowmelt) limits water availability. Many plants survive in this cold desert by remaining dormant under the snow much of the year; they the...
In recent decades, scientists have noted a surge in Arctic plant growth as a symptom of climate change. But without observations showing exactly when and where vegetation has bloomed as the world's coldest areas warm, it's difficult to predict how vegetation will respond to future warming. Now...
net effect on plant community composition [11]. Here, one might expect a decoupling between abundance and ecosystem effect. Despite the extensive literature on herbivory in the Arctic [12], there has been no comprehensive attempt to synthesize the impacts of herbivore diversity on tundra ecosystems...

North America encompasses a wide range of climate and ecosystems types including Arctic tundra in northern Canada and Alaska, boreal forest, the Canadian prairies and American plains, temperate forests in eastern and western Canada and the United States, arid and semi-arid regions of the south-west...
react-text: 117 This book is a report of investigations of several small ponds on the arctic tundra near Barrow, Alaska. The main study, which ran from 1971 through 1973, was funded from three sources: The National Science Foundation, the State of Alaska through the University of Alaska, an...

Tundra Ecosystems The tundra ecosystems are treeless regions of land in the Arctic and the ops of mountains. The climate is cold and windy and rainfall is scarce. Cool fact:The tundra ground is often permanently frozen so trees cannot grow there. ...
