FACTORS INFLUENCING STREAM INVERTEBRATE COMMUNITY STRUCTURE ACROSS PRAIRIE TYPES IN THE GREAT PLAINS
Prairie streams are highly threatened ecosystems. Most of what is known about them comes from studies conducted at the Konza Prairie Biological Station, a tallgrass prairie preserve located in northeastern KS. We compared ecosystem metrics and invertebrate community structure across thirteen headwater streams draining tallgrass, mixed-grass, and shortgrass prairies. Invertebrate abundance (p = 0.035) and community structure (p = 0.001) differed significantly with prairie type, although there was high variability within prairie types. Chlorophyll-a (R2 = 0.36, p = 0.001), discharge (R2 = 0.32, p = 0.01), mean monthly temperature (R2 = 0.29, p = 0.009), and percent erosional habitat (R2 = 0.19, p = 0.081) were among the variables linked with differences in community structure. Composition of invertebrate feeding functional structure (R2 = 0.63, p = 0.001) and habits (R2 = 0.50, p = 0.026) differed by site, and voltinism differed by site (R2 = 0.55, p = 0.021) and prairie type (R2 = 0.27, p = 0.007). This study highlights how regional climate, basal resources, and local hydromorphic factors shape community structure in prairie streams, and the high variability in prairie stream ecosystem structure.
