An Experimental Investigation of Life History Variation in Native and Introduced Populations of <em>Silene latifolia</em>
… explore the biology of species in native and introduced ranges. The goal of my thesis is to determine if an invasive plant has had a shift in life history traits after introduction. The study species was <em>Silene latifolia</em>. Also, when organisms leaves their native range, they also …

Competitive interactions in a dairy pasture containing paspalum (Paspalum dilatatum Poir,) following the introduction of ryegrass (Lolium perenne L.)
… of trials investigated the contribution of introduced grasses (Lolium perenne and Bromus catharticus) to seasonal production of a high yielding dairy sward containing paspalum (Paspalum dilatatum). The persistence of the introduced species was also determined. Autumn overdrilling improved …

Preference and performance of the Wild Indigo Duskywing (<i>Erynnis baptisiae</i>) on its native host Yellow Wild Indigo (<i>Baptisia tinctoria</i>) and on the introduced plant Crown Vetch (<i>Securigera varia</i>)
… Wild Indigo (<em>Baptisia tinctoria</em>) to the introduced plant Crown Vetch (<em>Securigera varia</em>). This study examined the effects of this host shift by comparing butterfly preference (larval feeding and female oviposition) and performance (pupal weight and pupation success) of two …

How do ecological restoration treatments affect understory plant communities in dry conifer forests of the Colorado Front Range?
… be considered – such as effects on understory plants. Several studies have investigated outcomes of ecological restoration thinning treatments for understory plants, but few of these have examined effects across a landscape and at a time interval long enough for plants to potentially adjust to …

Seaweed Invasions and Novel Chemical Defences
… in invaded areas. The reasons why some introduced species become dominant and widespread in their new environments is still largely an unsettled question. It has commonly been predicted that introduced plants will invade when they are less affected by herbivores, since this will provide …
