Limitations and Potential of Satellite Imagery to Monitor Environmental Response to Coastal Flooding
RAMSEY, E. III; WERLE, D.; SUZUOKI, Y.; RANGOONWALA, A., and LU, Z., 2012. Limitations and potential of satellite imagery to monitor environmental response to coastal flooding. Journal of Coastal Research, 28(2), 457–476. West Palm Beach (Florida), ISSN 0749-0208. Storm-surge flooding and marsh response throughout the coastal wetlands of Louisiana were mapped using several types of remote sensi...
Saltmarshes in subtropical Queensland, Australia, are assumed to provide habitat for fish, yet there has been no evidence as to whether fish actually occur on the intertidal flats that constitute the main area of marshes. Nor has there been any assessment of differences in fish use of vegetated habitat and the extensive unvegetated saltpans that occur naturally and because of human activities. ...
Open marsh water management (OMWM) is a selective ponding-and-ditching technique for saltmarsh mosquito control that encourages consumption of mosquito larvae by native larvivorous fishes while eliminating or reducing larval rearing habitats. OMWM has been successfully practiced in Delaware since 1979, and after 28 years of use actively continues today. After some refinement of the state’s init...
The study compared the relationship of the contract plan of student evaluation and a traditional type of evaluation, for changes in knowledge and attitudes during a college course in ecological relationships. The Syracuse Environmental Awareness Test was used to measure both cognitive and affective changes. In the experimental group the contract, plan of evaluation was utilized. Subjects were e...
Stable carbon isotope ratios of bacterial biomarkers were determined to infer sources of organic carbon used by bacteria in the sediments of three salt marshes. Biomarkers studied were polar lipid-derived fatty acids (PLFA), mainly bacteria-specific, methyl-branched i15 : 0 and a15 : 0. Experiments showed that isotopic fractionation between substrate and biomarkers was relatively constant (24 t...
