The effect of timing of growing season drought on flowering of Andropogon gerardii
… of the dominant C4 grasses, in particular Andropogon gerardii which can contribute >80% to ANPP in this ecosystem. It is predicted that precipitation periods with the greatest impact on the highly variable flowering rates of A. gerardii are likely to be particularly important for …

Impact of mycorrhizal fungi and nematodes on growth of Andropogon gerardii Vit., soil microbial components and soil aggregation
… 96 microcosms (52×32×40cm) were planted to Andropogon gerardii Vit. so that a third of the microcosms could be destructively sampled at the end of each growing season for three years. Plant biomass was separated into aboveground, rhizomes, and roots. All components were dried and weighed at …

The Potential Allelopathic Effect of Several Grass Species on Native Missouri Prairie Plant Species
… species, Sorghastrum nutans (Indian grass), Andropogon gerardii (big bluestem), Bothriochloa bladhii (caucasian bluestem), Panicum virgatum (switch grass), and Schizachyrium scoparium (little bluestem), were tested in petri plates for two weeks for potential allelopathic effects on five …

A Study of the Effect of Herbicides on Mycorrhizae Associated With Native Warm Season Grass
… applied to seedlings of Tripsacum dactyloides, Andropogon gerardii, Panicum virgatum L., and Sorghastrum nutans (L.) Nash. growing in native prairie and sterile soil. All herbicide treatments caused a negative effect on plants and mycorrhizal colonization. Plant survival was directly correlated …

Plant Species and Soil Type Effects on Root Characteristics, Microbiota and Plant-soil Feedback Responses in Four Prairie Species
… integrifolium, Aster novae-angliae and Andropogon gerardii were grown in sterilized control soil and soil collected from beneath monocultures of A. laevis, P. integrifolium, and A. gerardii. Soil type (heterospecific and conspecific sources) was expected to have the largest influence on …

Assessment of stockpiling methods to increase late summer and early fall forage biomass
… (Panicum virgatum L.), big bluestem (Andropogon gerardii Vitman), indiangrass (Sorghastrum nutans (L.) Nash), and little bluestem (Schizachyrium scoparium (Michx.) Nash)). Native warm-season grasses produced much higher yields than all tall fescue types but the nutritive value was not …

Quality and Yield Responses of Seven Warm Season Forage Grasses to Partial Shading in a Simulated Silvopasture in East Texas
… virgatum),</em> ‘Kaw’ Big Bluestem (<em>Andropogon gerardii</em>), ‘Americus’ Indiangrass (<em>Sorghastrum nutans</em>), ‘Harrison’ Florida Paspalum (<em>Paspalum floridanum</em>), and Nacogdoches Eastern gamagrass (<em>Tripsacum dactyloides</em>). The experimental design was a two-way …

Using Plant Functional Traits to Estimate Prairie Restoration Species Composition
… altissma, Poa pratensis, Solidago rigida, and Andropogon gerardii. Older sites were much more varied in their species composition with no species being dominant in the older sites. Maxent correctly predicted at least 50% of the dominant species in 7 out of 11 of the sites. The sites with most …

Assessing the Phytoextraction of Organic and Inorganic Pollutants From Point Pelee National Park, Ontario and Iqaluit, Nunavut
… biomass. Of all plant species studied in PPNP, Andropogon gerardii (big bluestem) was deemed to have the most potential for phytoextraction because it had a large biomass and accumulated high amounts of all four contaminants of interest. For this reason, it was selected for a follow-up …

Legume Establishment in Native Warm-Season Grass Pastures
… interseeded into mixed 'Niagara' big bluestem (Andropogon gerardii Vitman), 'GA Ecotype' Indiangrass (Sorghastrum nutans Nash), and 'Camper' little bluestem (Schizachyrium scoparium) pasture in 2022 and 2023 at the Southern Piedmont AREC in Blackstone, Virginia. Planting method at three levels …

The Suitability of Native Warm-Season Grasses for Equine
… (Sorghastrum nutans) and big bluestem (Andropogon gerardii) hays by horses were 1.3% and 1.1% of BW/d, significantly lower than orchardgrass (Dactylis glomerata), an introduced cool-season grass, at 1.7% of BW/d. Biomarkers for toxicity remained within acceptable ranges for all …

Functional diversity of fungal symbiont communities and the impact of biotic and abiotic factors on their composition and assembly
… endophytes associated with the prairie grass, Andropogon gerardii, to better understand the processes generating and maintaining functional diversity in this key group of plant symbionts. I found that fungal endophyte communities are comprised of phylogenetically distinct assemblages of slow- …

When do propagules matter? The role of ecological filters and regeneration dynamics during community assembly in tallgrass prairie restorations
… a split plot design with sown dominant grasses (Andropogon gerardii, Schizachyrium scoparium, and Sorghastrum nutans) and subordinate species (three unique pools of non-dominant species) as the subplot factor, with treatment (control vs. suppression of dominant grasses) as the sub-subplot factor, …
