Meta-community theory and stream restoration: evidence that spatial position constrains stream invertebrate communities in a mine impacted landscape. Restoration Ecology, 23(3), 284-291. Summary: Researchers set out to determine/quantify the importance of local-scale landscape conditions on macroinvertebrate community assembly and dispersal. Results indicate that landscape condition and habitat connectivity impact the biodiversity present in the stream. Research Goals:
Dispersal of macroinvertebrates is the limiting factor on recolonization and restoration success. Most restoration relies on the field of dreams hypothesis. Must involve multi-scale and regional-scale factors to improve chances of success. Meta-community framework is where species are regulated by local pressures and dispersal is regulated by different spatial scales. There are four models: 1) neutral model, 2) patch dynamics, 3)species sorting, and 4) mass effects. Questions:
