The species of plants and animals living in the Arctic exhibit an extensive range of adaptations including morphology, growth and allocation, storage and internal recycling, and mode of reproduction. Arctic tundra includes only a small fraction of the world's biotic diversity. Tundra plants have ...
The regions in which plants and animals can survive are changing. Some species are able to survive further north than they were previously could. In the tundra(冻原), trees used to be only low growing plants with shallow roots that could live in permafrost(永久冻土) trees have appeared Lees...
Polar ecosystem, complex of living organisms in polar regions such as polar barrens and tundra. Polar barrens and tundra are found at high latitudes on land surfaces not covered by perpetual ice and snow. These areas lying beyond the tree line comprise m
The tundra is a biome, or a large area of land where there is a community of plants and animals in the same climate. Other biomes you might know are tropical rain forests or deserts. The word tundra means land without trees. But what kind of plants and animals could live in such a ...
Even though conditions in the world’s coldest biome are harsh, many plants and animals call it home. Tundra plants tend to be small and live in clumps, and they include mosses, lichens and liverworts, plus grasses, sedges, and dwarf shrubs. These plants are food for animals like arctic...
Permafrost does for instance limit the opportunities for Arctic animal to dig out dens and burrows, and it favours plants that do not require a deep root system. On the tundra you can encounter fairly large grazing Arctic animals like caribou and muskox, as well as smaller herbivores like ...
