Local Adaptation for Life-History Traits in Silene Latifolia
… how species adjust post colonization. The plant Silene latifolia was introduced to North America (NA) from Europe (EU) in the 1800s. The goal of this thesis was to test if Silene latifolia has become locally adapted across its range. My first experiment tested local adaptation of germination …

Quantifying Environmental Maternal Effects in the Invasive Plant, Silene Latifolia
… was to quantify EME using a plant species, Silene latifolia, which is native to Europe and invasive in North America. I did this by experimentally comparing the amount of variation in life history traits between two generations: Natural (Parent) and Uniform (Offspring). The Parent generation …

Population Genetics and Speciation in the Plant Genus Silene (section Elisanthe)
… and population genetics in the plant genus Silene (section Elisanthe). The introductory chapter is a literature review covering characteristics of the species studied, and the current literature on their evolutionary dynamics and population genetics. The second and third chapters cover …

Role of Hybridization in a Biological Invasion: An Experimental Study with Silene Latifolia
… invasion success by using the agricultural weed Silene latifolia as a model. I used a common garden experiment to examine whether crossing parents of different ancestry results in offspring with differing quality. Plants were pollinated in three treatments reflecting parent plants within the same …

An Experimental Investigation of Life History Variation in Native and Introduced Populations of <em>Silene latifolia</em>
… after introduction. The study species was <em>Silene latifolia</em>. Also, when organisms leaves their native range, they also escape their natural enemies. The escape-from-enemies hypothesis theorizes that plants which escape natural enemies will shift more energy to growth and reproduction. …

The Role of Evolutionary Processes in a Biological Invasion: An Experimental Study with <em>Silene latifolia</em>
… using the aggressive agricultural weed, <em>Silene latifolia</em>. <em>Silene latifolia</em> is native to Europe and was introduced to North Amenca 200 years ago with the spread of agriculture. It has already been shown that this plant escaped its enemies upon introduction, but it is not …

Importance of floral scent compounds for the interaction between Silene latifolia (Caryophyllaceae) and the nursery pollinator Hadena bicruris (Lepidoptera: Noctuidae)
… between the nocturnal Caryophyllaceae Silene latifolia, and the noctuid moth Hadena bicruris was determined. This insect-plant relationship is one of the known nursery pollination systems, where pollinators reproduce within the flowers they pollinate. Silene latifolia is a dioecious …

Silene otites (Caryophyllaceae): Attraction of nectar-seeking mosquitoes to inflorescence odours, and temporal variation of flower scent and flower visitors
… of flower odours in attracting mosquitoes to Silene otites were evaluated. Although mosquitoes are known to visit diverse flowers for nectaring, S. otites is one of only two plant species world-wide in which mosquitoes have been described as pollinators. In several investigations flower odours …

Silenes: Novel Reagents for Organic Synthesis
Whilst silenes have long been studied for their unique chemistry there has been little attempt to exploit this in other synthetic strategies. As part of a programme to explore this aspect the reactions of readily accessible silenes with alkenes and dienes were studied. Silenes, generated by the …

Doubly Bonded Derivatives of Si and Ge: Cycloaddition Reactions and Polymer Chemistry
… tert-butoxide were added to the highly reactive silene Mes2Si=CHCH2t-Bu and the germene Mes2Ge=CHCH2t-Bu, in diethyl ether. 1,2-Addition products were obtained regioselectively and in good yield after treatment with a weak acid with no evidence for any rearrangement products and no polymerization …

Seed Dispersal by Aquatic Turtles
… spp., Ranunculus sceleratus, Setaria spp., and Silene dichotoma were observed in the fecal matter. Following the initial survey the study mainly focused on two omnivorous aquatic turtles, the common snapping turtle (Chelydra serpentina) and the red-eared slider (Trachemys scripta). Large numbers …
