  • Direct and indirect effects of livestock grazing intensity on processes regulating grassland bird populations

    Creator:
    Johnson, Tracey N.
    Abstract:
    In grasslands, grazing by large ungulates can influence vegetation structure, composition, primary productivity, and ultimately, ecosystem functioning. While grazing represents a complex disturbance, grazing intensity largely determines the effects of grazing on vegetation. Structural and compositional changes in the plant community caused by grazing could have bottom-up effects on species...

  • Using local climate to explain temporal variation in rare plant populations

    Creator:
    Pfingsten, Ian A.
    Abstract:
    Increased temperatures due to anthropogenic-induced climate change may raise the threat of extinction for taxa with sessile life histories (e.g., plants) in the near future. Linking climate change models to demographic models may provide useful insights into the potential effects of environmental changes on rare plants, and therefore aid in...
