Investigating rates and mechanisms of lateral erosion in a small bedrock river using erosion pins, structure-from-motion photogrammetry, and optically stimulated luminescence dating: Konza Prairie, northeast Kansas
Bedrock rivers play a critical role in landscape evolution by leaving signatures of past climate shifts, base level changes, and tectonic uplift in the landscape. While much is known about the mechanics of vertical bedrock incision, the fluvial processes driving lateral bedrock erosion and the …

Demography and leaf physiology of Cornus drummondii in response to disturbance in tallgrass prairie
… nitrogen, and water relations. In tallgrass prairie, the increased cover and abundance of woody species is typically attributed to human activities such as decreased fire frequency and increased grazing intensity. Clonal shrubs are of particular concern because of their ability to spread via …

Interactive effects of fire and grazing on soil and forage nitrogen dynamics in a tallgrass prairie
… regulators of nutrient cycling in tallgrass prairie ecosystems, yet their combined effects on soil nitrogen (N) dynamics and links to forage quality across heterogeneous landscapes remain incompletely resolved. This thesis examined how fire frequency, grazing, and landscape position interact …

Systematics and reproductive biology of the genus Morus L. (Moraceae)
… assessed hybridization between these species at Konza Prairie Biological Station (KPBS). Both species are subdioecious, and Flint Hills populations exhibit significantly male-biased sex ratios, with sex expression being size independent. Approximately 10% of individuals of each species changed …

Infiltration controls in a tallgrass prairie at a hillslope scale
… properties at ten sites along a hillslope in Konza Prairie Natural Research Area. Several analysis methods were used to extract hydraulic conductivity and sorptivity values from the infiltration data. Next, large intact soil cores were extracted from three selected sites at the same hillslope …

Impact of mycorrhizal fungi and nematodes on growth of Andropogon gerardii Vit., soil microbial components and soil aggregation
… superactive, mesic Cumulic Hapludolls located at Konza Prairie Biological Station, Manhattan KS. The experiment was a three-way factorial in a complete randomized block design with four replications. The three factors were mycorrhizae (M), nematodes (N), and phosphorus (P). In a greenhouse study, …

Análise de footprint e eficiência no uso da água em pastagem natural
… Ecológica (NEON) na Estação Biológica da Konza Prairie (KPBS) em 2017, 2018 e 2019. Uma parametrização de um modelo de footprint (FFP) foi utilizada para determinar a área de influência dos fluxos turbulentos. Foi observado que em 2018 a área agregada de contribuição para os fluxos no …
