PRACTICING BENTHIC SCIENCE IN THE UNDERGRADUATE LABORATORY: ANALYZING A LARGE DATA SET GENERATED BY FRESHWATER BIOLOGY STUDENTS
Freshwater Biology is an elective course for biology, environmental science and environmental studies majors at the University of Minnesota Morris. All students participate is a project in which they examine the macroinvertebrate community in the Pomme de Terre River. Working in groups of 2-3, students collect benthic samples from coarse, fine an organic substrates. Students sort and learn to identify macroinvertebrates using taxonomic keys and contribute to a large class data set that is suitable for statistical analysis. Students compare taxon richness and abundance and investigate the occurrence of different functional feeding groups among habitats. In the 4 offerings of Freshwater Biology since 2011, taxon richness and abundance rarely differ significantly among habitats. However, functional feeding groups consistently differed among habitats and revealed a macroinvertebrate community dominated by collector-gatherers and collector-filterers. Students further investigated the occurrence of specific taxa and consulted primary literature to strengthen their interpretation of the data and understanding of the macroinvertebrate community dynamics in the Pomme de Terre River. Identifying macroinvertebrates, manipulating and presenting data, and properly reporting and interpreting results are skills valuable skills in benthic science.
