The tundra ecosystem exhibits dramatic seasonal changes that significantly influence the behaviors and migration patterns of its wildlife. Animals in the tundra have adapted to the extreme conditions and take advantage of the region"s short summer and long winter in various ways.

• Migration for Food and Reproduction: Many tundra animals migrate seasonally in search of food, better conditions, or for reproductive needs. This includes a variety of species, from large mammals like caribou, which migrate to find fresh grazing grounds, to birds such as geese and terns that travel vast distances between their wintering grounds and the tundra.
• Adaptation to Seasonal Changes: Animals like the Arctic hare, Arctic fox, and ptarmigan exhibit seasonal changes in their physical appearance, such as white winter coats for camouflage against the snow. Polar bears, primarily marine animals, spend winter on ice floes hunting seals, while in summer, they are found on land.
• Impact of Climate Change: Climate change is altering migration patterns, with some species beginning their migrations earlier each year. This can affect the synchronization of food availability, breeding seasons, and the survival of both predators and prey in the Arctic ecosystem.
• Population Oscillations: The tundra"s animal populations, particularly that of lemmings, experience significant oscillations, which in turn affect the populations of their predators, such as snowy owls and Arctic foxes. These population cycles are a key aspect of the tundra"s ecological dynamics.
• Historical Migrations: Some tundra animals, including the polar bear and Arctic fox, are circumpolar, having migrated across continents via land bridges in ancient times. Their presence across the Arctic tundra is a result of extensive historical migrations.

These behaviors and patterns underscore the complex and interconnected nature of the tundra ecosystem, highlighting the resilience and adaptability of its inhabitants. However, the ongoing impacts of climate change pose new challenges, making the study and conservation of these migration patterns more important than ever.

In the tundra, the harsh conditions and limited resources foster a range of interactions among species, from mutually beneficial partnerships to competitive relationships. These interactions are crucial for survival in this extreme environment.

• Mutualism: An example of mutualism in the tundra is the relationship between lichens, which are combinations of fungi and algae. The algae, through photosynthesis, produce food that nourishes both organisms, while the fungi provide a structure for water absorption and mineral intake, benefiting both parties.
• Commensalism: The tundra also displays commensal relationships, such as between reindeer and Arctic foxes. Reindeer, while foraging for food, inadvertently expose subnivean mammals and insects, which the Arctic fox then preys upon, benefiting without harming the reindeer.
• Parasitism: Parasitic interactions are present as well, with various parasites affecting mammalian species like reindeer, Arctic foxes, and musk oxen. Tapeworms, for example, can develop inside these hosts, consuming their food and potentially leading to malnutrition or death.

These symbiotic relationships, along with predation and competition for scarce resources, form a complex web of interactions that define the tundra ecosystem. Despite the challenging conditions, these interactions ensure the survival and continuation of the tundra"s unique biodiversity.

Recent research and studies have significantly advanced our understanding of tundra biodiversity, emphasizing the impact of climate change on this fragile ecosystem.

Increasing land surface temperatures and precipitation are predicted to cause major transformations in these ecosystems, affecting biodiversity and ecological processes.
• Experimental Warming Studies: Long-term experimental warming, coupled with increased snow depth, has shown distinct trajectories for soil fungal communities in dry and moist tundra types. These studies reveal that while both warming and increased snow depth significantly affect fungal community composition and soil variables in dry tundra, moist tundra is mainly affected by summer warming.
• Impact on Soil Fungi: Fungi play key roles in arctic ecosystems as mutualistic symbionts, pathogens, and decomposers, with most arctic plants highly dependent on associations with mycorrhizal fungi. Changes in climate are expected to influence these fungal communities, potentially altering their interactions with plants and the overall ecosystem function.
• Feedback Mechanisms: The expansion of shrubs in response to climate change is noted to have positive feedback on ecosystem change through increased snow accumulation, soil insulation, and nutrient mineralization. This, in turn, supports further shrub growth and expansion, impacting regional temperatures and climate forcing.

These studies underscore the complexity of interactions within the tundra ecosystem and the significant impact of climate change on its biodiversity. As the tundra undergoes transformation, understanding these dynamics becomes crucial for predicting future changes and developing conservation strategies.
