| Human development effects on fish communities in two northern Michigan lakes | |

Rivers, Lakes, & Wetlands, Studies have shown that human development has negative effects on lake nutrients and habitats, so we hypothesized that development would also have negative effects on fish diversity, species richness and abundance. We compared two lakes in Northern Michigan, Burt and Douglas Lake, to examine how human development had affected fish assemblages. We collected fish from two sites in developed Burt Lake, and two sites in undeveloped Douglas Lake. We left minnow traps out for one to two days, and seined twice at each site. We also compared nutrient and water chemistry data between the two lakes. We found significant differences in species diversity between the two lakes, as well as between two of the paired sites. We also, found that Perca flavescens of presumably the same age were larger at Douglas Lake than Burt Lake. Habitat complexity was compared between the two lakes, and was found to be related to increases in diversity, richness and abundance. We found that habitat complexity had a greater effect on fish community than level of development., http://deepblue.lib.umich.edu/bitstream/2027.42/61509/1/Mindell_Ilana_2008_RLW.pdf |
