Position Description: The objective of this work is to develop experimental knowledge of how global change factors (e.g., sea-level rise) impact wetland ecosystems and to determine feedback effects on processes controlling habitat stability and other emergent properties of ecosystems. Research also focuses on rates and patterns of root growth and contributions to soil formation, elevation change, and carbon sequestration in coastal wetlands. Other objectives are to understand how wetland systems are impacted by small-scale disturbance events. The research will focus on how shifts in species composition of transitional plant communities and environments influence ecosystem functions such as accommodation of sea-level rise and support of estuarine food webs.
This individual will conduct field sampling in Louisiana, Florida, and Texas in saline wetlands where tropical mangroves converge with temperate salt marsh species. Experiments will involve measurement of changes in accretion and elevation change of the marsh surface, soil physicochemical characteristics, above and belowground plant production and vegetation structural complexity. Specific skills required: · Background in ecology with emphasis on biogeochemistry and/or quantitative chemical analysis · Knowledge of basic laboratory analytical procedures · Field experience in wetlands or similar habitats requiring boat use · Ability to summarize field and laboratory data into tabular, graphic, or narrative form using appropriate computer software (e.g., Excel, SAS, or Sigma Plot) · Knowledge of basic statistical techniques and programs · Ability to interpret results and prepare reports and manuscripts · Experience with the following equipment is a plus: CNS Analyzer, LACHAT Autoanalyzer, ICP, water level gauges, elevation measurements. Requirements: The position requires a bachelor?s degree and knowledge/experience in biology, ecology, botany, soil science, or marine science. Must work independently within established guidelines and operational procedures to ensure uniform data collection between field personnel and succeeding years of data collection and sampling. One-year experience in data entry and knowledge of PC-based computer systems is required. Advanced degree a plus.
