FWE01 Effects of browsing and fire on woody encroachment at Konza Prairie

Woody encroachment into grasslands, savannas, and steppes have become a management and conservation concern worldwide because of the ability of woody plants to change ecosystems through decreases in biodiversity, alterations in water and nutrient cycles as well as decreases in forage production and quality. In grasslands, woody encroachment can be categorized into two groups: non-resprouting species that can be killed with fire and resprouting species that cannot be killed with fire.

SMP01 Spatial variation of soil microbial processes under Cornus drummondii shrubs of varying size at Konza Prairie, 2017

Data set ID:

Soil was collected from multiple locations under individual Cornus drummondii shrub islands of varying size to measure within-shrub heterogeneity in soil microbial processes. Soil chemistry (Total C, Total N, extractable inorganic N, extractable P, and organic matter cotent), microbial biomass C and N, and potential extracellular enzymatic activity of β-glucosidase, phosphatase, NAG-ase, and LAP-ase were measured. Potential carbon mineralization and the isotopic composition of respired soil carbon was measured over a 77-day laboratory incubation.

SLP01 Leaf physiology in response to fire and climate within Cornus drummondii shrubs at Konza prairie

DOI:

Woody encroachment threatens the loss of remaining grasslands. Clonal shrubs are of particular concern because of their ability to resprout after disturbance, spread vegetatively, and share resources among interconnected stems. These traits contribute to the encroachment of deep-rooted clonal shrubs in tallgrass prairie. In this study, we investigated how leaf physiological traits differ among interconnected stems within a dominant encroaching shrub in tallgrass prairie, Cornus drummondii.

WER01 Elevated CO2 counteracts effects of water stress on woody rangeland-encroaching species at Konza Prairie

Woody plants are increasing prevalence and dominance in many rangelands around the world. The reason for their increase is various but two common drivers that have changed are an increase in CO2 concentrations and alteration to precipitation dynamics. We asked what the physiological growth dynamics of four juvenile woody plant species (Cornus drummondii, Rhus glabra, Gleditsia triacanthos and Juniperus osteosperma) when grown in elevated CO2 and chronically water stressed.
