Environmental DNA as a valuable and unique source of information about ecological networks in Arctic terrestrial ecosystems

摘要: Arctic terrestrial ecosystems are particularly vulnerable to the effects of ongoing and predicted climate changes. The current states environmental biodiversity ecological networks in need be known understood monitor how they change these changes may influence particular components ecosystem. Despite fact that tundra is generally poor nutrients, it has a surprisingly high biodiversity, especially invertebrates microorganisms. Besides macroclimatic features, there local factors influencing such as microclimate, water availability, or large seabird colonies depositing guano. This last can have substantial impact on soil’s physicochemical consequently distribution, number, diversity tundra-associated plants animals vicinity colony. Changes functioning ecosystem at all trophic levels difficult investigate using traditiona...
