Effects of UV Radiation on Tundras 
Tundras are vast, treeless regions found in the
Arctic and Antarctic characterized by low temperatures, permafrost, and a short growing season
...While some
plants have developed mechanisms to protect themselves from UV damage, excessive exposure can lead to reduced growth, decreased reproductive success, and changes in plant community composition
...
Human Impact on Tundra Biomes Tundra biomes are vast, cold, and treeless landscapes found in the
Arctic and high mountain regions
...The vegetation in tundra regions consists of low-growing
plants such as mosses, lichens, and dwarf shrubs
...
Tundra Ecosystem Functions and Health Overview of the Tundra Ecosystem The tundra biome is found in the
Arctic and Antarctic regions, as well as at high altitudes on mountains around the world
...The tundra is known for its treeless landscape, with low-growing
plants such as mosses, lichens, and shrubs dominating the vegetation
...
Vegetation Types Studied Grasslands Grasslands are vast areas dominated by grasses and other herbaceous
plants ...Tundra The tundra is a cold, treeless biome found in the
Arctic and high mountain regions
...
Seasonal Variability Tundra These
plants have developed strategies to survive in the cold, nutrient-poor soil of the tundra
...Species such as caribou,
Arctic foxes, and polar bears are able to withstand the cold temperatures and scarcity of food in the tundra
...
Cold Desert Adaptations Explained Despite the extreme conditions, many
plants and animals have developed remarkable adaptations to survive and thrive in these challenging environments
...Polar Bears: While primarily associated with
Arctic regions, polar bears can also be found in cold deserts
...
Impact of Climate Change on Tundra Species are altering the distribution of plant species in the tundra, which in turn is affecting the animals that depend on these
plants for food and shelter
...For example, a study conducted in the
Arctic National Wildlife Refuge found that the warming climate is causing the shrub cover in the tundra to increase, which is altering the habitat for many bird species that breed in the region
...
Impact of Climate Extremes on Tundras Tundras are vast, treeless regions found in the
Arctic and high mountain regions characterized by low temperatures and a short growing season
...Excessive rainfall can lead to waterlogging of the soil, making it difficult for tundra
plants to survive
...
Permafrost Thaw Effects These changes disrupt habitats for
plants and animals, causing shifts in species distribution and biodiversity loss
...Table: Examples of Species Affected by Permafrost Thaw Species Impact
Arctic fox Loss of denning sites due to collapsing permafrost Caribou Changes in migration patterns and food availability Arctic willow Altered growth and reproduction
...
Role of Snow Cover in Tundra Insulation and Protection For many tundra
plants and animals, snow cover provides a protective layer against the harsh winter conditions
...Table: Snow Cover in Different Tundra Regions Tundra Region Snow Cover Duration Snow Depth
Arctic Tundra 8-10 months 30-60 cm Alpine Tundra 6-8 months 20-40 cm Antarctic Tundra 12-14 months 50-100 cm
