Shedding Light on Biological and Ecological Function
… molecular interaction, structure, coloration and function within biological and ecological systems. Herein, electronic spectroscopy will be utilized to evaluate novel fluorescence probes for studies of peptide-protein interactions and viscosity. The efficacy of three non-natural amino acid probes …

Urban Restoration Ecology: Investigating environmental change, ecological function, and enrichment planting
… continues despite growing evidence that intact, functioning ecosystems are critical to human health and well-being. The field of restoration ecology has rapidly developed as a response to ameliorate the damage by investigating how to re-build ecosystems. This branch of science generally posits …

Evaluating ecological function provided by bank stabilization in Box Canyon Reservoir, WA
… bank stabilizing materials can radically alter ecological functions provided by native shoreline vegetation. Despite valid concerns regarding the use of riprap in bank stabilization, limited pre- and post-project monitoring make it difficult to assess a project's ability to provide a healthy, …

Distribution and Ecological Function of Pacific Lamprey in the San Luis Obispo Creek Watershed
<p>Pacific lamprey (<em>Entosphenus tridentatus</em>) is an endemic species to coastal watersheds along the Pacific Rim in North America and Asia. The species' geographic distribution is retracting and has not been mapped precisely, and the ability for the species to provide ecosystem services, …

Evaluation of Ecological Function of Urban Riparian and Stream Systems: Guiding Ecological Restoration in Austin, Texas, USA
Restoration ecology seeks to restore ecosystem function and biodiversity in natural systems impacted by human activities. Restoration of riparian areas is a common recommendation of water management plans today and often deemed necessary to maintain ecosystem sustainability. Assessment of the …

Applying Wetland Rating Systems to Assess Functions of Depressional Wetlands Created by a Mass Wasting Feature, Table Mountain, Washington
… this research, no studies had analyzed wetland function by using the Washington State Wetland Rating System in subalpine environments. Therefore, supplemental methods were used to enhance the quantification of ecological function. Results indicate high-elevation wetlands perform highest with …

The ecology of venom use in the Javan Slow Loris (Nycticebus Javanicus) and its implications for conservation
… explore sources for venom sequestration and the ecological function of slow loris venom, which has never been studied before. I examined the hypotheses that venom is used for intraspecific competition, predator defence and/or (ecto-) parasite avoidance. From April 2012 to June 2013 I observed 12 …

Comparison of Heterotrophic Activity in Forested Streams Originating from Wetland and Agricultural Tile Drainage Sources
… water chemistry) that are important drivers of ecological function. To assess the influence of agricultural tile drainage inputs on stream ecosystem function, I compared heterotrophic activity (i.e., organic matter breakdown and benthic respiration) in forested streams originating from wetland …

Proposed Mechanism Explaining Seasonal Biological Foaming in Activated Sludge Systems; Foam-Causing Bacteria Specialize in Consuming Lipids
… populations and the determination of their ecological function. Diurnal rRNA profiles were then measured for bacterial populations found in full-scale activated sludge wastewater treatment plants, and the experiment support the assumption that mycolata specialize in consuming lipids.

Patterns, Processes And Models Of Microbial Recovery In A Chronosequence Following Reforestation Of Reclaimed Mine Soils
Soil microbial communities mediate important ecological processes and play essential roles in biogeochemical cycling. Ecosystem disturbances such as surface mining significantly alter soil microbial communities, which could lead to changes or impairment of ecosystem functions. Reforestation …

Heterogeneity of Stand Structure, Fuels, and Wildfire Hazard in Dry and Moist Old-Growth Ponderosa Pine Forests: Case Studies from Western Montana
… treatments are increasingly proposed to restore ecological function and remediate catastrophic wildfire hazards in old-growth ponderosa pine stands throughout the western United States. However, stand heterogeneity has been inadequately addressed in restoration and fuel treatment planning. In …

Ecological minimalism: an approach for designing urban parks
As defined by the author, “Ecological Minimalism” means an intervention in the design of already developed spaces, which improves ecological function while increasing flexibility and amount of use. As a method for design, Ecological Minimalism prioritizes the subtraction of existing materials over …

Experience-Oriented Ecological Design: A Methodological Framework to Improve Human Experience in Urban Public Space Ecological Design
… the premise that contemporary urban public space ecological designs. Are often deficient in this regard. In order to develop a design methodology that addresses both ecological function and sensory experience, the author examine both contemporary western ecological design and classical Chinese …

Locational and temporal patterns in microorganisms potentially affecting water quality in the Dan River system
… face numerous stressors that impact both ecological function and water quality. In 2015-16, municipalities along the Dan River in southern Virginia experienced repeated taste and odor (TandO) issues in their drinking water that originated from the river source water. Given that the source …

Evaluation of a Water Budget Model for Use in Wetland Design
Wetland ecological function greatly depends on the wetland hydrology. As a result, correctly estimating the wetland water budget, is essential to the success of created wetlands. A wetland water budget model, Wetbud, was developed by collaborators from Virginia Tech, Old Dominion University, and …
