Consequences of interaction between the native ant community and an invasive plant (Euphorbia esula)
… of interaction between an invasive plant (Euphorbia esula L., Euphorbiaceae) and the native ant community during both the seed and flowering plant stages, and (2) how both the ant and plant benefit from myrmecochory (ant-mediated seed dispersal). My research had three main objectives: (1) …

Interplay between competition and evolution in invaded and native plant communities
… complex ecological interactions between Euphorbia esula, an invasive plant, and Balsamorrhiza sagittata, a native plant. I found that direct negative effects of Euphorbia on Balsamorrhiza, due to competition, were greatly reduced by indirect positive effects. In the second chapter, I …

Biological control affects native vegetation and recovery potential in Theodore Roosevelt National Park, North Dakota
… recovery in areas infested with leafy spurge (Euphorbia esula L.) and treated with the bio-control agent Aphthona spp. and examined in-situ seed bank potential to predict recovery of native species. Extant vegetation and seed bank species richness, diversity, composition and community …

CAN SHEEP CONTROL LEAFY SPURGE WITHOUT COMPROMISING EFFORTS TO RESTORE NATIVE PLANTS?
… the ecological effects of using sheep to control Euphorbia esula (leafy spurge). While sheep can effectively reduce E. esula when used as a long-term management strategy, little is known about their impacts on native plants. The efficacy of sheep grazing for restoration depends both on its …
