  • Seed and seedling ecology of Artemisia tridentata in a restoration context

    Creator:
    Wijayratne, Upekala C.
    Abstract:
    The semi-arid sagebrush steppe ecosystem is one of the largest biomes in North America. The steppe provides critical habitat and forage for wildlife and is economically important to recreation and livestock industries. However, the ecosystem is threatened primarily due to several negative effects associated with expansion of the exotic annual...

  • Yield responses of invasive grasses to carbon doses

    Creator:
    Brunson, Jessi L.
    Abstract:
    The sagebrush steppe ecosystem of the northern Great Basin is severely degraded and continues to decline due in large part to the invasive, non-native annual grasses Bromus tectorum L. (cheatgrass) and Taeniatherum caput-medusae (L.) Nevski (medusahead). Restoration of invasive-dominated areas is difficult, but can be enhanced by adding a carbon...

  • Limitations to Seedling Regeneration on Tropical Forest Restoration Plantations in Northern Thailand

    Creator:
    Sangsupan, Hathai A.
    Abstract:
    This dissertation investigated potential ecological limitations to seedling regeneration in young, seasonally dry, evergreen forest restoration plantations in northern Thailand. We explored whether recruitment of colonizing tree species in the restoration plantations can be attributed to seed dispersal mode (i.e. abiotic or animal dispersal) and seed size. We did this...
