Wetland landscape dynamics and its socio-ecological implications
… without wetlands, which have benefits that serve ecological values for both plants and animals. Wetlands have been loosely defined as a transitional habitat between aquatic systems and highlands; they may be a part of coasts, estuaries, floodplains, or watersheds of surface waters. As a relatively …

Ecological implications of allelopathic interferences with reference to Phragmites australis
… and study with the rise in understanding of its implications and potential disproportionate influence. However, identifying allelopathy and consequent phytotoxic effects as an important mechanism of plant invasion is a difficult task due to the potential for an individual plant to have many …

Mechanisms and ecological implications of resistance to predation by heterotrophic ciliates expressed by marine bacteria
Bacteria are dominant organisms in the marine environment, providing the foundation for food webs that are essential for ecosystem structure and function. The ubiquity of bacteria in the marine environment is a result of their capacity to survive in many different niches. This is largely due to the …

Effects of Anthropogenic Urea on Lakes of the North American Great Plains: Ecological Implications Based on Experimental and Observational Studies
… a consequence of human activities may exacerbate ecological problems associated with eutrophication (e.g. increased productivity of aquatic fauna, deep water anoxia, biodiversity loss, fish kills, etc.), especially in phosphorus (P)-rich aquatic ecosystems. Biweekly measurements of urea content …

Ecological implications of introducing Leucaspius delineatus (Heckel, 1843) and Pseudorasbora parva (Temminck and Schlegel, 1842) into inland waters in England
… investigated the establishment, dispersal and ecological implications of introducing the two non-native fish species, sunbleak Leucaspius delineatus (Heckel, 1843) and topmouth gudgeon Pseudorasbora parva (Temminck and Schlegel, 1842) to inland waters of England. The introduction and initial …

Changes in avian diversity and potential invasive seed dispersal post-wildfire in a Southeastern deciduous forest; Flipper Bend Woods, Signal Mountain, Tennessee
… deciduous forests, fire-disturbance and its ecological implications have not been heavily studied. In Tennessee, a recently burned site (2016) presented a unique opportunity to analyze habitat regrowth two-three years after a major wildfire thought to have been worsened by invasive plants. In …

Behavioral type - environment correlations in three-spined stickleback
… affected important evolutionary and ecological processes in the three-spined stickleback (Gasterosteus aculeatus). In the first chapter I documented two such behavioral type-environment correlations, one between boldness and social environment and the other between exploratory …

Against the Grain: A History and Policy Analysis of Rice, Water and the Edible Landscape in Egypt
… considerate of the larger socioeconomic and ecological implications they help produce. In this dissertation, I explore the history of rice cultivation in Egypt and its regulatory context under water stress conditions as a tool for legitimizing and promoting specific claims to water use over …

Traffic models from a velocity point of view and implementation of traffic conditions in excess fuel consumption estimates
… of attention, for it has major economic and ecological implications for the design and maintenance of road networks. As any dissipative mechanisms, the ones we find in the interaction of the pavement and the vehicles are highly dependent on the velocity of the agents in the system, hence the …

Examining Positive Distraction as a Coping Strategy for Chronic Stress
… one of the first attempts to characterize the ecological implications and underlying mechanisms of positive distraction use. In one set of studies, I examined the real-world implications of using positive distraction across four samples, comparing it to both avoidance and neutral distraction …

Variation in Salamander Life History and Community Composition Across an Urban Gradient in Atlanta, Georgia, USA
… The results of this research help to assess the ecological implications of urban development by expanding our understanding of the mechanisms underlying variation in <em>E. cirrigera</em> life history and the impacts of urbanization on salamander species richness.</p>

Modeling the temperature response of small rivers to land cover changes using satellite-based spatial data
… including river temperatures, has important ecological implications. However, there is a dearth of information on temperature of rivers smaller than about 60 m wide (approximately fifth order and below), which constitute roughly 97% of total global stream length: for such rivers, field …

Weed management practice selection among Midwest U.S. organic growers
… (IWM) systems have been developed to address the ecological implications of weeds and weed management in cropping systems, but adoption is minimal. Organic agriculture may be the most promising context for application of IWM due to philosophical similarities between these two approaches to the …

Fluctuating human activity and associated anthropogenic food availability affect behaviour and parental care of Red-winged Starlings
