Community-Level Phylogenetic Diversity Does Not Differ Between Rare And Common Lineages Across Tallgrass Prairies In The Northern Great Plains, Sarah A. Herzog, Maribeth Latvis
Community-Level Phylogenetic Diversity Does Not Differ Between Rare And Common Lineages Across Tallgrass Prairies In The Northern Great Plains, Sarah A. Herzog, Maribeth Latvis
Native Plant Focused Publications
Niche differentiation has served as one explanation for species coexistence, and phylogenetic relatedness provides a means to approximate how ecologically similar species are to each other. To explore the contribution of rare species to community phylogenetic diversity, we sampled 21 plant communities across the Prairie Coteau ecoregion, an area of high conservation concern. We used breakpoint analysis through the iterative addition of less abundant species to the phylogenetic tree for each community to assess the contribution of rare species to community phylogenetic diversity. We also quantify the phylogenetic signal of abundance using Blomberg's K statistic and calculated the phylogenetic similarity …

The quantity of grass-root exudates varies by season, suggesting temporal shifts in soil microbial community composition and activity across a growing season. We hypothesized that bacterial community and nitrogen cycle-associated prokaryotic gene expressions shift across three phases of the growing season. To test this hypothesis, we quantified gene and transcript copy number of nitrogen fixation (nifH), ammonia oxidation (amoA, hao, nxrB), denitrification (narG, napA, nirK, nirS, norB, nosZ), dissimilatory nitrate reduction to ammonia (nrfA), and anaerobic ammonium oxidation (hzs, hdh) using the pre-optimized Nitrogen Cycle Evaluation (NiCE) chip. Bacterial community composition was characterized using V3-V4 of the …

Native Plant Focused Publications
The Great Plains is a mixture of cropland and grassland mainly used for agricultural purposes, with grasslands under continual threat of conversion to cropland. Agriculturists are advocating for the integration of crop-livestock systems (ICLS) to recouple nutrient cycles, improve biodiversity, and increase resilience of agricultural operations. We address the benefits of ICLS in the Great Plains, contending that focus on improving soil health and financial stability of agricultural operations should reduce the conversion of grasslands to cropland. Using US Department of Agriculture National Agricultural Statistics Service Census of Agriculture survey data from the 1925−2017 category “cropland used only for pasture …

The Great Plains of North America encompass approximately 1,300,000 km2 of land from Texas to Saskatchewan. The integrity of these lands is under continual assault by long-established and newly-arrived invasive plant species, which can threaten native species and diminish land values and ecological goods and services by degrading desired grassland resources. The Great Plains are a mixture of privately and publicly owned lands, which leads to a patchwork of varying management goals and strategies for controlling invasive plants. Continually updated knowledge is required for efficient and effective management of threats posed by changing environments and invasive plants. Here we discuss …

Impact Of Mature, Female Eastern Red Cedar (Juniperus Virginiana L.) Trees On Soil Seed Bank In The Mixed-Grass Prairie Of The Northern Great Plains, Austin Domeier, Lan Xu, Alexander Smart
Native Plant Focused Publications
Eastern red cedar (ERC) (Juniperus virginiana L.) trees are invading prairies throughout the Great Plains due to fire suppression and overgrazing. This encroachment poses a threat to native plant communities in terms of their reproduction, regeneration, diversity, and invasiveness. It is unknown how ERC trees impact belowground propagules in the mixed-grass prairie and how it may alter heterogeneity. The objective of this study was to evaluate how mature female ERC trees impact the soil seed bank composition. In October 2020 in southcentral South Dakota ten female ERC trees with canopy diameters = 5-10 m, similar environmental characteristics, and isolated from …

Development of perennial biomass cropping systems is focused on maximizing biomass yield with minimum inputs, particularly nitrogen (N) fertilizer. Historical breeding efforts have focused on increasing biomass yield but have ignored N-use efficiency. The purpose of this study was to quantify the increased N demand associated with realized gains in biomass yield from big bluestem (Andropogon gerardii Vitman) and switchgrass (Panicum virgatum L.) breeding programs. Nitrogen demand was highly variable across locations and years, ranging from − 1.7 to + 6.8 kg N Mg−1 DM, with an average of 2.2 kg N Mg−1 DM. Increases in N demand were closely …

The North American Great Plains tallgrass prairie was once a system of native cool and warm season grasses, which have been degraded by non-native invasive plants. Native grass restoration is highly desirable to improve ecosystem functions and productivity. In this two-year study, the impact of fire, herbicide, and nitrogen on productivity and the presence of invasive species [primarily the cool season grass, smooth brome (Bromus inermis Leyss.)] and native warm season native grass species [big bluestem (Andropogon gerardii Vitman), sideoats and blue grama (Bouteloua curtipendula (Michx.) Torr.), and B. gracilis (Willd. Ex Kunth) Lag. ex Griffiths] were investigated. Spring fire …

Silphium perfoliatum L., cup plant, has potential as a new multi-purpose crop. It is pollinator-friendly and has biodiversity enhancement, conservation, economic, and medical potential. In eastern South Dakota, S. perfoliatum can produce more than 20 Mg (million grams) ha-1 of biomass and 0.09 Mg ha-1 of seed in agronomic plantings. The giant eucosma moth, Eucosma giganteana (Riley), is a major pest of agronomic S. perfoliatum in the region. We provide a summary of this insect and its association with its host. Our experimental objectives were to determine if the frequency of rhizome occupation by late instar larvae and if their …

Native Plant Focused Publications
Groundplum milk-vetch (Astragalus crassicarpus Nutt.) is a native legume found on gravelly to sandy prairie uplands throughout central North America. The large and fleshy fruits, or pods, of this species were consumed by indigenous people and European settlers, and are cached by rodents. Our previous research on native legumes of the northern Great Plains indicated seed predation by insects, notably bruchid beetles belonging to the genus Acanthoscelides Schilsky, was a dominant factor determining viable seed production in natural and artificial plant assemblages. However, although we have studied the reproductive biology of several species of Astragalus L., none had fleshy pods. …
Reproductive Biology Of American Licorice (Glycyrrhiza Lepidota Pursh) In Western South Dakota With New Seed Insect Associations, Arvid Boe
Native Plant Focused Publications
American licorice (Glycyrrhiza lepidota Pursh) is a long-lived rhizomatous native legume that is common on moist prairies and meadows in the northern Great Plains and further west. This species is of interest for remediation and conservation because it is a legume that is fairly well adapted to moist saline soils. It is browsed by deer and pronghorn and its seeds are consumed by birds, rodents, and insects. Acanthoscelides aureolus (Horn) (Coleoptera: Chrysomelidae)] and Bruchophagus grisselli McDaniel & Boe (Hymenoptera: Eurytomidae) can decimate seed production in natural populations. Our objectives were to determine seed yield components (i.e., seeds per pod and …

Smooth bromegrass (Bromus inermis) is a Eurasian C3 perennial grass. It was introduced to North America in 1884 to control soil erosion and for pasture improvement, but has been outcompeting the native grasses of the northern Great Plains, decreasing diversity and altering habitats. Control of smooth bromegrass is a key to improve degraded native dominated grasslands. However, current practices have minimal or only short term effects due to extensive rhizome and tiller production by bromegrass. Even though vegetative reproduction via the belowground bud bank is the primary means for its invasiveness and persistence, the effect of management on its bud …

Canada milk-vetch (Astragalus canadensis L.), North America’s most widespread species of Astragalus, is important for herbivores and granivores in natural ecosystems but suffers heavy seed losses to bruchids and curculionids. Our objectives were: (1) compile a species inventory and describe life histories of insects associated with seed production in Canada milk-vetch, and (2) determine frequencies of pod predation and primary parasitism in Canada milk-vetch. The seed predators were Acanthoscelides perforatus (Horn) and Tychius liljebladi Blatchley. Frequency of pod predation varied between two plant populations (46 and 70%) and between A. perforatus (37 %) and T. liljebladi (21 %). The primary …
