Seasonal correlations between Pueraria montana var. lobata and avian species diversity and relative abundance in Hamilton County, Tennessee
Invasive species exist outside of their native ranges and can cause environmental harm where they have been introduced. One such species is kudzu (Pueraria montana var. lobata), an invasive vine in the southeastern U.S. Although kudzu is one of the most common invasive species management concerns …

Process oriented infrastructure for climate-driven forest migration through cities
… been made to translocate tree species from their native ranges to locations where the climate is projected to be suitable in the future (known as assisted migration). However, there are concerns that such translocations may not be successful and may lead to unpredictable adverse consequences. This …

Genome-wide diversity assessment for genetic resource management of Eucalyptus dunnii, E. grandis, E. nitens and E. urophylla
… spanning the diversity present in the native ranges of these species hosted in South African provenance trials and genetic conservation parks. The objectives of this MSc study were to: i) investigate genome-wide genetic variation in E. nitens, E. dunni, E. grandis and E. urophylla and …

Biology and ecology of bigheaded carp in an invaded ecosystem
… environmental cues than those from their native ranges and was dependent on growing degree day rather than changes in river discharge. Hybrid bigheaded carp (silver x bighead carp) were not different from silver carp in any of the characteristics examined (i.e., movements, condition, diet) …

Avian ecology and rapid morphological change in a novel plant-frugivore system
… The morphology and foraging behavior of non-native species can influence their ability to fulfil functional roles; however, the relationship between form and function may change as they experience morphological change. My research aimed to describe the rapid morphological change of the main …

Hummingbird Hovering Energetics and Flight Capacities Across Elevational Gradients
… to perform aerobic activities across their native ranges. Examination of morphology has previously indicated that high elevation species may have disproportionately larger wings than their lower elevation counterparts, hypothesized to be compensatory for high elevations. My analysis of …

The Role of Evolutionary Processes in a Biological Invasion: An Experimental Study with <em>Silene latifolia</em>
… 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 known whether the success of this plant has also …

The role of sound and sociability in the success of invasive lionfish (Pterois spp.)
… different to those experienced in their native ranges. In these cases, if and how invasive species use different forms of information to inform their decision-making in invaded regions is likely to influence their invasive success. For marine invaders, sound is likely to be a particularly …

Bee Abundance Along a Tropical Montane Elevational Gradient and Implications for Crop Pollination Services
… as species with narrow elevational ranges or specialization within a narrow portion of their elevational range are predicted to be more vulnerable to range shifts.Beyond my assessment of elevation specialization in Neotropical bee species, I conducted an additional study to identify …

An Experimental Investigation of Life History Variation in Native and Introduced Populations of <em>Silene latifolia</em>
… studies that 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 …

The consequences and implications of ecology on body size distributions in social insects
… conditions throughout their introduced ranges (e.g. fewer competitors and access to additional resources). These differences in ecology likely impact colony investment in growth, reproduction, and defense. Moreover, the success of invasive species is thought to occur as a result of …
