Book Description
Sericea lespedeza [Lespedeza cuneata (Dumont) G. Don] is a rangeland weed of the tallgrass prairie of Kansas. Experiments were carried out during the 2001-2003 growing seasons (June-November) to examine the relationship between sericea lespedeza and other rangeland species, wildlife use and dispersal of sericea lespedeza propagules, and the relationship between sericea lespedeza stubble height and utilization by livestock. Sericea lespedeza cover was positively correlated with violet lespedeza (r=0.25) [Lespedeza violacea (L.) Pers.], heath aster (Aster ericoides L.) (r=0.23) and total forb cover (r=0.56). Sericea lespedeza composition was negatively correlated with big bluestem (Andropogon gerardii Vitman.) (r=-0.27) and sideoats grama [Bouteloua curtipendula (Michx. Torr.)] (r=-0.27) composition and positively correlated with western ragweed (Ambrosia psilostachya D.C.) (r=0.21) and violet lespedeza (r=0.36) composition. Sericea lespedeza density was inversely related to forb species richness on all sites. On half the sites, there was also an inverse relationship between grass species richness and sericea lespedeza density. Grazed sites had less difference in grass species richness between high and low levels of sericea lespedeza densities. There was no evidence of an ecological threshold to the detriment of species richness with increasing sericea lespedeza density. Cattle digestive processes did not affect sericea lespedeza germination. Quail digestive processes enhanced germination of the few seeds that were excreted. Quail diet selection was investigated with a field study. Five out of 49 crops collected contained seed classified as sericea lespedeza. None of these seeds germinated in the greenhouse. Both cattle and quail could potentially disperse sericea lespedeza seed, but voluntary consumption appears to be low for both species, at least during November when other food is available. An height-weight table estimating percent utilization for various grazed and ungrazed heights of sericea lespedeza was constructed. Coefficient of determination values were greater than 0.85 between plant height and weight, indicating that the heightweight method was appropriate for estimating sericea lespedeza utilization. Using additional regression analysis, a chart for estimating forage from percent of plants grazed was constructed.

Book Description
Lespedeza cuneata [(Dumont) G. Don] is a perennial legume first introduced to North America from eastern Asia in 1896 and is now widespread and well established across much of the eastern and central United States. Possible impacts of invasion and mechanisms of spread however are poorly understood. I assessed the influence of three L. cuneata cover classes (i.e., 5%, 15 - 20%, and 25% per m2) on a small mammal community in eastern Oklahoma (February 2010 to December 2011). I also examined the relationship between local fire history and L. cuneata cover and also considered the effect of plant invasion on the vegetation community in these same areas. My results indicate small mammal community diversity decreased with increasing L. cuneata cover, while Sigmodon hispidus body mass and catch rate increased with increasing L. cuneata cover. Lespedeza cuneata invasion decreased numbers of other species, such as Peromyscus maniculatus, Neotoma floridana, P. attwateri, and Microtus pinetoru. Model selection and multimodel inference indicated catch rates for common species were most influenced by vegetation height and occurrence of bare ground, while L. cuneata cover and vegetation richness exerted variable influence. For the fire history analysis, mean fire return interval (MFI) alone explained 75% of the variation in L. cuneata cover and the relationship was negative. Additionally, L. cuneata invasion suppressed graminoid cover. I provide evidence to indicate continued loss of habitat heterogeneity due to L. cuneata invasion will likely favor a community composed of relatively few, but individually abundant small mammal species. My findings also reveal for the first time the possible relationship between MFI and L. cuneata cover. My dissertation adds to the literature that indicates invasive plants are capable of modifying habitat structure and ecological conditions under which native organisms evolved.
