    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.

  • Recruitment predictors of an endangered prairie species : a case study of Erigeron decumbens

    Creator:
    Gallagher, Katie J.
    Abstract:
    Preservation of rare plant species often requires establishment of new populations. Survivorship surveys are the most common method of post-introduction monitoring. However, they provide an incomplete picture of establishment success. This study is an attempt to develop a model for determining establishment success by determining the factors affecting recruitment in...

  • 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...
