Human wildlife interactions (HWI) pose a complex challenge for wildlife managers. Human encroachment into wildlife habitat and the growing number of outdoor recreationists are increasing the frequency of contact and conflict, especially in regions such as the Front Range of Colorado. Geographic information systems (GIS), which use a combination of remote sensing and environmental survey data, allow for predictive spatial analyses of where human wildlife interactions are likely to occur. I used publicly reported observations of moose to create spatial predictive maps in a species distribution model framework. Slope and elevation were shown to be the strongest predictors of HWI, …
Using Dendrochronology To Create A Timescale Of Succession On Nurse Logs In The Olympic Temperate Rainforest, Sean Grealish
Using Dendrochronology To Create A Timescale Of Succession On Nurse Logs In The Olympic Temperate Rainforest, Sean Grealish
Summer Research
Previous work on the Olympic peninsula in Washington State has shown that recently fallen trees provide a germination location for seeds that cannot do so on the forest floor due to thick moss mats. My field work over two summers dating and surveying nurse logs yielded a crossover at ~70 years where ground mosses start to dominate over tree mosses and seedling abundance begins to decrease.
Is Context Dependency Imperative To Understanding The Impacts Of Invasive Plants?, Brendan B. Haile
Is Context Dependency Imperative To Understanding The Impacts Of Invasive Plants?, Brendan B. Haile
Masters Theses
Introduced exotic species have a tendency to become invasive and impact local biological communities. Invasions often impact community attributes such as cover and species richness, but these factors may also regulate patterns of invasion. In such cases, impacts may be dependent on the invasion context. We used data from the Buell-Small Succession Study, a long-term permanent plot study in the piedmont region of New Jersey, to document context dependency in invasion. To do this, we analyzed the factors that affected the colonization and growth of four invasive species, Alliaria petiolata, Lonicera japonica, Microstegium vimineum and Rosa multiflora, as well …

Investigating The Ecology Of A Rare Species On St. John, Usvi: Reintroducing Solanum Conocarpum In Light Of Climate Change, Cecilia Rogers
Investigating The Ecology Of A Rare Species On St. John, Usvi: Reintroducing Solanum Conocarpum In Light Of Climate Change, Cecilia Rogers
Senior Honors Projects, 2010-2019
Approximately two thirds of St. John is National Park territory. However, the land has been threatened with tourism and development, greatly impacting island biodiversity. One species that may become extinct due to this degradation is Solanum conocarpum. S. conocarpum is a rare shrub, endemic to the dry tropical forests of St. John, USVI. This plant is a species of conservation concern and is one of very few native and endemic plants on this island. Very little is known about the ecology and reproduction of S. conocarpum. Most plants are found on the southern half of the island. Recent observations …
Experimental Greenhouse And Field Trials On American Ginseng, Panax Quinquefolium: Implications For Restoration In Appalachia, Emily Thyroff
Experimental Greenhouse And Field Trials On American Ginseng, Panax Quinquefolium: Implications For Restoration In Appalachia, Emily Thyroff
Senior Honors Projects, 2010-2019
Panax quinquefolium, American ginseng, is one of the more valuable non-timber forest products, NTFPs, providing economic, cultural, and ecological ecosystem services in forests. Although ginseng has a broad distribution range, it is not abundant anywhere due to overharvesting and deer browse. This study included experimental field and greenhouse trials to determine optimal growing conditions given inconsistencies regarding aspect and soil. Three soil series and two aspects (represented by soil moisture in the greenhouse) were manipulated in a factorial design. We hypothesized that there would be significant differences in ginseng performance (germination, survival, leaf area, and height) due to soil and …
