Arctic ecosystems are complex and fragile ecosystems that exist in the Arctic region, which includes parts of North America, Europe, and Asia. These ecosystems are characterized by extreme cold temperatures, permafrost, and limited biodiversity. They are home to unique and specialized flora and fauna that have adapted to survive in harsh Arctic conditions. Research in Arctic ecosystems focuses on understanding the impacts of climate change, pollution, and human activities on these fragile environments. Scientists study the interactions between different species, the role of key species in the ecosystem, and the effects of environmental changes on Arctic biodiversity. They also investigate the carbon cycle and the role of Arctic ecosystems in regulating global climate. Overall, research in Arctic ecosystems plays a crucial role in informing conservation efforts and policy decisions to protect these vulnerable and important environments.
