Precipitation Variability And Nitrogen Deposition Alter Root Distribution In A Tallgrass Prairie, Emmalyn P. Terracciano, Michael Schuster, Jeffrey Dukes
Precipitation Variability And Nitrogen Deposition Alter Root Distribution In A Tallgrass Prairie, Emmalyn P. Terracciano, Michael Schuster, Jeffrey Dukes
The Summer Undergraduate Research Fellowship (SURF) Symposium
Climate change and increases in nitrogen deposition impact ecosystems globally. Projected atmospheric warming allows rain to fall in larger events with longer dry periods in between, increasing rainfall variability in many regions. Concurrently, the combustion of fossil fuels and the heavy use of nitrogen fertilizers continue to increase the availability of nitrogen globally. However, not much is known about how these global change factors, increased rainfall variability and nitrogen deposition, interact with each other to affect ecosystem functions, particularly belowground where root production contributes to soil carbon pools- an important component in regulating climate. In order to study these factors, …
Evaluating Contaminants Of Emerging Concern In Commercial Biosolid-Based Fertilizers, John Hemmerling, Michael L. Mashtare, Linda S. Lee
Evaluating Contaminants Of Emerging Concern In Commercial Biosolid-Based Fertilizers, John Hemmerling, Michael L. Mashtare, Linda S. Lee
The Summer Undergraduate Research Fellowship (SURF) Symposium
The production and popularity of commercially available biosolid-based fertilizers are increasing because of their economic, environmental, and plant nutrition benefits, particularly in urban and suburban areas. Because biosolid-based fertilizers are derived from waste water treatment plant residuals, we hypothesized that there is the potential for micropollutants to persist in these products. Their presence would be of particular concern due to their potential impact on human and ecological health and risk of bioaccumulation. This study involves quantifying contaminants of emerging concern in three biosolid-based fertilizers, and 2 non-biosolid-based fertilizers, a composted animal manure and an organic compost. Our extraction method employed …
The State Of The Upper Bay Of Panama Wetlands: Ecological Significance, Environmental Policy, Urbanization, And Social Justice, Madeline A. Price
The State Of The Upper Bay Of Panama Wetlands: Ecological Significance, Environmental Policy, Urbanization, And Social Justice, Madeline A. Price
Celebration
I conducted this research while studying abroad with SIT Panama: Tropical Ecology, Marine Ecosystems, and Biodiversity Conservation. This is a multidisciplinary investigation of the Upper Bay of Panama wetlands, a 49,000 hectare region east of Panama City that features mangrove, intertidal mudflat, and grassland habitat internationally recognized as a stopover site for two million shorebirds every migration season. However, with economic pressure to increase urban development in the area, this land’s protected status under the Ramsar convention was suspended for a year in April 2012. By compiling scientific studies, news articles, photographs, and interviews with local conservationists and community members, …
Salmonid Early Response To Restored Freshwater Floodplain, Erin Morgan, Jeffery R. Cordell, Lauren Rich
Salmonid Early Response To Restored Freshwater Floodplain, Erin Morgan, Jeffery R. Cordell, Lauren Rich
Salish Sea Ecosystem Conference
Shortly after the construction of the Hansen Creek floodplain restoration project in 2010-2011, we conducted a pilot study of the initial use of the site by juvenile salmonids and the early development of invertebrate communities. We found that juvenile Coho salmon collected from the restored floodplain during periodic inundation events had higher instantaneous rations (a measure of feeding intensity) than Coho collected during regular monthly sampling in the creek channels. The floodplain site also had consistently higher insect abundances. Applying the data and lessons learned from the pilot study, we undertook a more comprehensive 13-month study of Hansen creek and …
