The quality of these streams is comparable to a West Virginia-designated reference site, and the macroinvertebrate communities found in these streams, which are used as an indicator of quality, rank extremely high in comparison to other streams throughout the Central Appalachia ecoregion and the state of West Virginia.

I have studied the effects of eutrophication on fluvial macroinvertebrate communities, specifically their ecotoxicological impacts on aquatic species.

The diversity of fish and macroinvertebrate populations in small, spring-fed, canyon tributaries to the Cimarron River is greater than in nearby ecoregions.

In addition, after seven years of artificial enrichment of the Kuparuk River, the dominant primary producers changed from diatoms to mosses [26], which subsequently altered the abundance, distribution, and taxonomic composition of the macroinvertebrate community [27].

Specifically, Scrimgeour et al. [14] suggested that if these disturbances play a role in maintaining habitat complexity and associated species richness and diversity, then climate-related changes in the severity of these events will affect macroinvertebrate and aquatic algal species distribution and associated biodiversity patterns (see also Prowse and Culp [15]).

For example, there are pronounced north – south gradients in the taxonomic composition of stream macroinvertebrate communities in the Arctic, with decreasing species diversity and an increasing importance of taxa such as dipterans with distance northward [11].
