CFP01 Fish population on selected watersheds at Konza Prairie (Reformatted to a Darwin Core Archive)
This data package is formatted as a Darwin Core Archive (DwC-A, event core). For more information on Darwin Core see https://www.tdwg.org/standards/dwc/. This Level 2 data package was derived from the Level 1 data package found here: https://pasta.lternet.edu/package/metadata/eml/edi/340/2, which was derived from the Level 0 data package found here: https://pasta.lternet.edu/package/metadata/eml/knb-lter-knz/87/8. The abstract below was extracted from the Level 0 data package and is included for context: Fishes were collected by habitat (pool or riffle) at 6 sites in the Kings Creek watershed with a single-pass electrofishing survey with one person operating the electrofisher and two people dipnetting. Collections were made seasonally.
PVC02 Plant species composition on selected watersheds at Konza Prairie (Reformatted to a Darwin Core Archive)
This data package is formatted as a Darwin Core Archive (DwC-A, event core). For more information on Darwin Core see https://www.tdwg.org/standards/dwc/. This Level 2 data package was derived from the Level 1 data package found here: https://pasta.lternet.edu/package/metadata/eml/edi/342/2, which was derived from the Level 0 data package found here: https://pasta.lternet.edu/package/metadata/eml/knb-lter-knz/69/18. The abstract below was extracted from the Level 0 data package and is included for context: Canopy coverage and frequency were recorded in 20 circular 10 sq m plots. Six treatments were sampled, three ungrazed and three to grazed by native grazers. In each case one of the three watersheds was unburned, another burned annually in April, the third burned every four years in April. In each treatment two soils were sampled: a lower-slope deep fertile nonrocky soil (tully silty clay loam), and a shallow rocky soil (florence cherty silt loam) on level to gently sloping ridges. In 1983 another ungrazed annual burn area '1c' was added 'both tully and florence soils' because original area '1d' appeared aberrant.
WAT04 Root decomposition and nutrient dynamics are resistant to rainfall legacies in tallgrass prairie
Purpose: Litter decomposition is an important component of carbon (C) and nitrogen (N) cycling, and rates of mass loss and nutrient release are sensitive to current climate conditions. Growing evidence suggests that past climate conditions can exert legacies on soil C and N cycling, but little is known about how belowground decomposition dynamics relate to these climate legacies. Results: Root litter mass loss was resistant to most climate treatments. Contrary to expectations, decomposition rates were slowest in plots with a history of long-term irrigation and fastest under drought in lowland prairie. Similarly, mass loss rates were overall faster in the drier uplands. Changes in N concentration as a function of mass loss were similar across treatments and patterns of litter N release largely tracked mass loss. Conclusions: Changes in the decomposer community with long-term release from water stress may have led to slowed root decomposition, but these effects were subtle. Our results suggest that changes in decomposition rates are not a cause of observed climate legacy effects on C and N cycling in prairies.
CSM09 Small mammal host-parasite sampling data associated with the Consume herbivore exclusion plots across two burned and native-grazed watersheds at Konza Prairie
Data set contains summaries of the number of individuals of each species of small mammal captured (relative abundance) on each trapping grid. Each record contains date, treatment, grid, trap station, species, specimen number, recapture status, specimen disposition, external body measurements (where applicable), reproductive information, and miscellaneous associated comments. These sampling records are based on nightly captures during one 4-night trapping period in fall (October concurrent with annual bison roundup activites) for each of 4 permanent trapping grids established on two fire/grazing treatments (two grids per treatment). These treatments are both grazed by native grazers (bison) and include one treatment burned annually (N1A) and one treatment burned every 4 years (N4B). In each treatment, sampling grids are arranged as 5 x 10 permanent stakes spaced 10m apart and labeled numerically between 1-50 for grid A and 51-100 for grid B. One grid per treatment (grid A) is sampled using capture-mark-release methods and the other grid in each treatment (grid B) is sampled using specimen removal and subsequent whole body processing and curation.
CBS06 Line transects surveys of breeding birds throughout Konza Prairie
Like CPB01 and PBG051, this dataset includes records of bird species based on line transect sampling. These surveys re-initiate most of the original KNZ transects surveyed from 1981-2009 (initiated by Zimmerma), continue the two focal 300-m transects conducted from 2011-2016 by Sandercock on watersheds C3A, C3B, C3C, C1A, and 1D, (but not the peripheral segments which have been dropped), and adds two new 300-m transects to additional watersheds with the goals of (i) replicating all surveyed treatments at the watershed level, (ii) adequately sampling the grassland habitats present on Konza as of 2017, (iii) capturing transitions in bird community in response to woody encroachment and fire reversal treatments. The goals are to document and quantify long-term changes in the population sizes of breeding birds at Konza prairie by obtaining a standardized measure of annual breeding bird abundance at the site level and individual watershed or treatment level.
PCN01 Plant and soil carbon and nitrogen pool data from the Belowground Plot Experiment at Konza Prairie

PSC01 Exploring effects on stream ecosystem properties by two size classes of prairie stream cyprinids
Losses in freshwater fish diversity might produce a loss in important ecological services provided by fishes in particular habitats. An important gap in our understanding of ecosystem services by fishes is the influence of individuals from different size classes, which is predicted based on known ontogenetic shifts in habitat and diet. I used twenty experimental stream mesocosms located on Konza Prairie Biological Station (KPBS), KS, USA to assess the influence of fish size on ecosystem properties. Mesocosms included two macrohabitats: one riffle upstream from one pool filled with consistent pebble and gravel substrate. There were four experimental and one control treatment, each replicated four times (N = 20). I used two size classes of Central Stonerollers (Campostoma anomalum) and Southern Redbelly Dace (Chrosomus erythrogaster). Five ecosystem properties were assessed: algal filament length (cm), benthic chlorophyll a (µg/cm2), benthic organic matter (g/m2), macroinvertebrate biomass (g/m2), and stream metabolism (g O2/m2/day1). Size structure of fish populations affected some, but not all, ecosystem properties and these effects were dependent upon species identity. Size structure of both species had effects on algal filament lengths where stonerollers of both size classes reduced algal filaments, but only small redbelly dace kept filaments short. A better understanding of the relationship between these prairie stream minnows and their small stream habitats could be useful to both predict changes in stream properties if species are lost or size structure shifts, and to redbelly dace populations, a Species In Need of Conservation.
SRM01 ShRaMPs (Shrub Rainout Manipulation Plots): interactive effects of drought and fire on grass and shrub physiology and productivity at Konza Prairie
ShRaMPs (Shrub Rainout Manipulation Plots) is a drought x fire experiment aimed at understanding the interactive effects of drought and fire frequency on tallgrass prairie communities experiencing varying degrees of shrub encroachment. Passive rainout shelters were constructed over existing, mature shrub islands and co-existing herbaceous communities on neighboring 1-year and 4-year burn watersheds (K1B and K4A). Shelters were either 'control' (ambient precipitation) or 'drought' (~50% precipitation reduction). A variety of leaf-level (gas exchange, water potential, turgor loss point, leaf δ13C) and whole-plant level (herbaceous and shrub biomass, plant water uptake) variables were measured during the 2019-2022 growing seasons to determine the physiological responses of a dominant C4 grass (Andropogon gerardii; big bluestem) and an encroaching clonal shrub (Cornus drummondii; rough-leaf dogwood). Soil volumetric water content was measured on-site for the duration of the experiment.
JST01 Juniperus virginiana seedling trial with and without bison at Konza Prairie
We report the results of a 30-year experiment at Konza Prairie, a mesic grassland in the Central Great Plains, under fire suppression (20-year fire return intervals) and experimental presence/absence of bison. Based on remote sensing, the land cover of deciduous trees was lower (6% grazed vs. 16% ungrazed) in bison-grazed areas. There was no difference between shrub land cover (42% grazed and 41%) and herbaceous land cover was higher in the grazed vs the ungrazed (51% grazed and 40% ungrazed). The land cover of evergreen trees (Juniperus virginiana L.)—which disproportionately decreases native biodiversity and increases wildfire risk—was approximately 0% with bison compared to 4% without bison. In a seedling trial of J. virginiana L., we found eight times greater over-winter mortality in the bison treatment. Juniperus virginina seedlings were transplanted with and without bison to compare mortality rates.

LTM01 Herbarium and grassland sites leaf trait measurements at Konza Prairie
Using herbarium specimens spanning 133 years and field-collected measurements, we assessed intraspecific trait (leaf structure and stomata) variability from grass species in the Great Plains of North America. We focused on two widespread, closely-related grasses from tribe Paniceae: Dichanthelium oligosanthes subsp. scribnerianum (C3) and Panicum virgatum (C4). Thirty-one specimens per taxon were sampled from local herbaria from the years 1887 – 2013 to assess trait responses across time to changes in atmospheric [CO2] and growing season precipitation and temperature. In 2021 and 2022, the species were measured from eight grasslands sites to explore how traits vary spatially across natural continental precipitation and temperature gradients. For temporal trends, we predicted Δ13C would decrease in D. oligosanthes and exhibit no change in P. virgatum. Dichanthelium oligosanthes is a C3 species, which we predict will respond to increased [CO2] concentrations by increasing its WUE to either conserve water while maintaining the same rates of photosynthesis or increase photosynthesis and maintain the same rates of water loss, thus decreasing Δ13C. We did not expect Δ13C of P. virgatum to respond over time because discrimination in C4 species is minimally affected by [CO2]. We also predicted both grasses will increase tissue C:N ratios and decrease stomatal density and stomatal lengths on both sides of the leaves in response to increased [CO2] over time. Lastly, we hypothesized %N and δ15N would decrease for both taxa. Because both taxa are widely distributed across North America and are known to exhibit variation in leaf morphology, we expected specific leaf area (SLA) to be greater in areas with warmer temperatures but not be correlated with differences in precipitation. We expect leaf dry matter content (LDMC) to increase with greater precipitation and decrease with higher temperatures.

LPT01 Leaf physiological and structural traits of encroaching shrub species at Konza Prairie
A variety of leaf-level physiological and structural traits were collected on seven species of encroaching shrubs at Konza Prairie Biological Station during the summer of 2022. Shrub species spanned an order of magnitude in abundance. These data were used to assess if the most abundant encroaching species at Konza Prairie have common growth forms and physiology or unique traits that differentiate their carbon- and water-use strategies. Measurements included A-Ci response curves, light response curves, pressure-volume curves, specific leaf area, leaf dry matter content, leaf carbon and nitrogen content, leaf 13C and wood density. All measurements were collected on the same shrub individuals.
DPP01 Drought experiment nested within the phosphorus plots experiment at Konza Prairie
We explore how nutrient-altered tallgrass prairie responds to drought. Seven years of nutrient treatments (control, nitrogen (N), phosphorus (P), and N+P) resulted in significantly different plant communities. Within this experimental context we imposed a three-year drought followed by three years of recovery from drought. We hypothesized (1) the plant functional types would have different responses to drought; (2) the different community types would vary in their resistance to drought; and (3) the control and P treated plots, where N is limited, will have a greater increase in standing biomass production in the previously droughted plots compared to the non-droughted plots.
SNE01 Species richness, community evenness (Evar) and ANPP effects of nitrogen addition across a gradient of 8 levels in a semi-arid shortgrass steppe and a mesic tallgrass prairie, 2014-2018
This dataset contains the first five years (2014-2018) of the effect of nitrogen addition on species richness, species evenness (Evar) and productivity for a long-term nitrogen addition gradient experiment in two North American grasslands: a semi-arid shortgrass steppe and a mesic tallgrass prairie. Fertilization with time-release urea has been on-going since 2014 in a gradient of eight levels: 0, 2.5, 5, 10, 15, 20, 30 g/m-2. The effect of nitrogen on richness, evenness and Aboveground Net Primary Productivity (ANPP g/m-2 yr) is calculated as the absolute change in value from control plots to treatment plots within each block.

PEW01 Plant species composition and edaphic properties in wallow and non-wallow plots at Konza Prairie
Bison wallows—bare depressions formed by repeated trampling and dust-bathing—introduce fine-scale heterogeneity to tallgrass prairie soils and plant communities. We compared plant communities and edaphic properties of wallows to adjacent non-wallow plots and cattle-grazed plots. Wallows had reduced organic matter and nitrogen but elevated clay and sodium. Non-fenced wallows had lower plant species richness than fenced wallows and all non-wallows. However, wallows supported distinct plant communities, including wetland species in temporary pools. While bison-grazed areas generally had higher plant diversity, wallows added localized variation not found in cattle or fenced plots. Our results suggest wallows function as small-scale ecosystem engineering features, shaping soil conditions and plant composition.
