Celebration of Learning
This project was performed at Augustana's Green Wing Environmental Laboratory and studied the richness and diversity of soil invertebrates in two conditions, deer poop enriched and surrounding soil. Soil invertebrates play an important role in soil quality which greatly affects ecosystems. The hypothesis of this study was that the diversity and richness would be the higher in the poop enriched soil samples. Soil samples were collected, Burlese funnels were used to collect the invertebrates, the invertebrates were examined under the microscope, and were assigned to taxa. The number of taxa (richness) and the number of individuals in each taxa (Simpson's …

Proper taxonomic and molecular study is necessary to better organize closely related species that may not only be used for human needs, but also in the quest for knowledge of how the world around us works. Though important, the taxonomic placement of Nebraskan and Iowan bird’s nest fungi (Nidulariaceae) is not well documented. Here, phylogenetic analysis is used to place the Nidulariaceae of Nebraska and Iowa in the tree of life using molecular and morphological techniques. Based on these results and results of further work done on these specimens, it will be possible to better place the Nidulariaceae of Nebraska …

Small Scale Heterogeneity In Vegetation Structure In A Patch-Burn-Grazing Landscape, Eric G. Behrens

Disturbances are drivers of spatial change in the plant communities of the tallgrass prairie ecosystem. Fire and large herbivore grazing are prevalent disturbances that maintain the vegetation structure and create spatial heterogeneity in vegetation at various scales. The fire-grazing disturbance interaction occurs when areas that have been recently burned are followed by intense grazing due to the high quality of forage regrowth. This interaction has been managed in tallgrass prairies in a homogenous method using uniform burning and grazing and a heterogeneous method using patch-burn-grazing (PBG). Vegetation heterogeneity at a large scale has been studied in PBG and uniformly managed …
