Invertebrates as webmasters in ecosystems.

Book cover for Invertebrates as webmasters in ecosystems.


The current understanding of invertebrates in terrestrial and terrestrially dominated (i.e. lower-order stream) ecosystems is reviewed and assessed. The book emphasizes the centrality of the activity of invertebrates (including arthropods, insects and nematodes), which influence ecosystem function far out of proportion to their physical mass in a wide range of situations, particularly at the inter...


Chapter 3 (Page no: 43)

Responses of grassland soil invertebrates to natural and anthropogenic disturbances.

This chapter aims to (1) summarize the major factors influencing invertebrate abundance and distribution in tallgrass prairie soils, focusing on the responses of selected soil invertebrate groups to natural disturbances (such as fire, grazing and drought); (2) identify potential linkages between changes in soil communities and the effects of disturbances on key plant and soil characteristics or processes; and (3) to discuss potential effects of novel anthropogenic perturbations (altered amounts of precipitation, elevated CO2 and increased N inputs) on soil communities and processes. It focuses on North American tallgrass prairies and draws upon studies undertaken at the Konza Prairie Long-Term Ecological Research site, with results from other grasslands where appropriate.
