Interplay between competition and evolution in invaded and native plant communities
… can also produce rapid evolutionary change in plant communities. Although our understanding of ecological and evolutionary interactions is growing, so far little is known about how competition among plants interacts with evolution to shape communities. In my dissertation, I use species …

Establishment of native plant species for livestock forage in silvopasture systems
… project takes a novel approach incorporating native rather than introduced forage species. Our objectives were to: determine success of establishment of native cool and warm season grasses, and native forb and legume species in two different existing silvopasture systems -- pitch pine (Pinus …

Quantifying the effects of Japanese knotweed (Fallopia japonica) allelopathy on native plant growth.
… japonica) is an invasive perennial herb native to east Asia that has become increasingly abundant in New York state. One way that invasive plants such as Japanese knotweed interfere with native communities is through the release of allelochemicals, which are secondary compounds that …

Conversion of Exotic Cool-Season Grasslands to Restored Native Plant Communities Utilizing Herbicide Treatments
… in maintaining, rehabilitating, and restoring native plant communities. Many areas in the northern Great Plains are now dominated by exotic cool-season grasses such as smooth brome (Bromus inermis), Kentucky bluegrass (Poa pratensis), and reed canarygrass (Phalaris arundinacea). Information was …

Disturbance impacts on non-native plant colonization in black spruce forests of interior Alaska
… historically been relatively free from invasive plants, there have been recent increases in the diversity and range of invasive plants in Alaska. It is critical that we understand how disturbances influence invasibility in northern boreal forests, to avoid the economic damage other regions have …

RESTORATION OF NATIVE PLANT COMMUNITIES AFTER ROAD DECOMMISSIONING: EFFECT OF SEED MIX AND SOIL PROPERTIES ON VEGETATIVE ESTABLISHMENT
… 1) short-term effects of road decommissioning on plant community composition, 2) effects of seed-mix seed origin (native vs. nonnative), species diversity, and seeding density on vegetative establishment, and 3) impact of overstory canopy and coarse woody debris on revegetation success on recently …

Cheatgrass (Bromus tectorum L.) management and native plant community recovery on sites selectively treated with Imazapic in Rocky Mountain National Park
… has become a threat to the montane and subalpine plant communities and ecosystems of Rocky Mountain National Park (RMNP). Cheatgrass aggressively invades disturbed sites and competes with native plant species by rapidly establishing a root system capable of depleting soil moisture and available …

"""A sturdy native plant"": The American Catholic education system, the American Catholic philosophy of education, and American Catholic identity, 1919-1972"
… the American Catholic Church labored against native Protestant beliefs that its Roman connections hampered Catholic assimilation into American life. Millions of ethnic Catholics lived in a culture dominated by white, Anglo-Saxon Protestants who expected conformity to their ideals of the …

Assessing the costs and benefits of native plant species for electric transmission line right-of-way revegetation within the Tennessee Valley Authority power service area
… vegetation on associated rights-of-way (ROWs). Native warm season grasses (NWSG) are more expensive for ROW revegetation compared to typical exotic cool season grasses (ECSG), but they may alter the successional trajectory such that long-term maintenance costs are reduced. I conducted a …

Effects of repeated early season herbicide treatments of curlyleaf pondweed on native macrophyte assemblages in Minnesota Lakes.
Non-native invasive species have the potential to cause various problems in small isolated ecosystems, these constraints are exemplified in the small, shallow, lakes of Minnesota. Curlyleaf pondweed (Potamogeton crispus L.) is one of the common occurring and most influential non-native invasive …

Distribution of non-native wetland plants is facilitated by urbanization and roads in the Chicago region
… facilitated the spread and establishment of non-native plant species. Urban areas have often been introduction points for species and have a combination of factors making them susceptible to invasion; including reduced habitat area, loss of unique habitat types, and increased nutrient run-off. …

Soil and compost tea: A new restoration technique?
… prairie restorations have lacked the plant diversity seen in remnant prairies. Most restoration practices focus on reestablishing the plant community but overlook the soil microbial community even though microbes are critical to habitat functioning. Developing techniques that increase …
