Invertebrates: Studies of Forest Arthropods
Arthropods represent a major component of forest communities where they play significant roles in processes of litter decomposition and nutrient cycling and serve as a food resource for wildlife species. Arthropods are also potentially valuable as indicators of environmental conditions and disturbance because they are highly sensitive to changes in habitat temperature and moisture regimes. The DEMO provides a unique opportunity (1) to evaluate arthropod responses to varying the amount or spatial distribution of green trees retained following harvest in Pacific Northwest forests and (2) to assess how changes in arthropod abundance and community composition affect other components of forest food webs.
