Response Of Stream Biofilm Function To Pulsed Increases In Velocity And Nutrients: An Artificial Stream Study, Chris Lucas
Electronic Thesis and Dissertation Repository
Pulsed increases in flow within streams alter abiotic conditions such as nutrient concentrations and velocity which can influence the function of stream ecology, including biofilms. A 31-day artificial stream experiment at Thames River Experimental Stream Sciences (TRESS) Centre, London, Ontario, assessed the response of stream biofilm function (decomposition, primary production, community respiration) to individual and combined increases in velocity and phosphorus associated with a 48-hour hydrological pulse event. There was some evidence of an interactive subsidy effect of increased phosphorus and velocity on algal productivity. Decomposition increased as a result of increased phosphorus but there was no synergistic interaction of …

Juvenile Hawksbill Residency And Habitat Use Within A Caribbean Marine Protected Area, Thomas H. Selby, Kristen M. Hart, Brian J. Smith, Clayton G. Pollock, Zandy Hillis-Starr, Madan K. Oli

Understanding the spatial ecology of highly mobile marine vertebrates is necessary for informing conservation and management strategies aimed at protecting such species. Buck Island Reef National Monument (BIRNM), off the coast of St. Croix, US Virgin Islands, harbors critical foraging habitat for Critically Endangered juvenile hawksbills Eretmochelys imbricata that exhibit high site fidelity until sexual maturation. Using an array of fixed passive acoustic receivers that covered over 20.2 km2 at its largest configuration and in-water biannual sampling, we analyzed residency patterns and habitat use of 29 hawksbills. High recapture rates allowed for long- term data collection for some individuals, with …

Integrated Approaches To Understanding And Reducing Drought Impact On Food Security Across Scales, Xiaogang He, Lyndon Estes, Megan Konar, Di Tian, Daniela Anghileri, Kathy Baylis, Tom P. Evans, Justin Sheffield
Geography
Understanding the cross-scale linkages between drought and food security is vital to developing tools to reduce drought impacts and support decision making. This study reviews how drought hazards transfer to food insecurity through changes in physical processes and socio-environmental systems across a wide range of spatial and temporal scales. We propose a multi-scale, integrated framework leveraging modeling advances (e.g. drought and crop monitoring, water-food-energy nexus, decision making) and increased data availability (e.g. satellite remote sensing, food trade) through the lens of the coupled human–natural system to support multidisciplinary approaches and avoid potential policy spillover effects. We discuss current scale-dependent challenges …

Recent U.S. And International Assessment Of Baltic Security Developments, Bert Chapman
Libraries Faculty and Staff Scholarship and Research
OBJECTIVES: The aim of this paper is to analyse Baltic security developments from U.S. government and military resources, scholarly journal articles, and multinational public policy research institute assessments. METHODS: The aim is to analyse the content and rhetoric within these resources to learn how those producing these materials view Baltic security developments and their viewpoints on how the U.S. and its allies should respond to these developments focusing on increasing Russian regional assertiveness. RESULTS: The author provides interpretations of Baltic security developments, Russian Baltic policy, and U.S. and NATO responses to these developments in materials produced by U.S. civilian and …
