The effects of temperature on diatom species richness and diversity in a streams lab facility from the Maple River of Northern Michigan.

Botany ResearchThe effects of temperature on diatoms species diversity and species richness were investigated at the University of Michigan Biological Station Streams Lab Facility located in Pellston, MI. Eighteen re-circulating closed PVC flumes were separated into three water treatments (averages of 18.4° C, 20.8° C, and 22.7° C) and water from the Maple River was pumped into each flume to ensure equivalent nutrient and chemical factors. Diatoms grew on ceramic tiles and diatom species composition was measured using species richness, relative abundance, and the Shannon-Weiner species diversity index. A T-test showed significant statistics among various weeks concerning species richness and diversity. As temphttp://deepblue.lib.umich.edu/bitstream/2027.42/57313/4/Mixson_Stephanie_2007.pd
