Improving biological control of giant salvinia in temperate regions PhD Assistantship Available at LSU for Fall 2017 or Spring 2018
Successful biological control of giant salvinia using Cyrtobagous salviniae has been extensively documented in tropical and subtropical regions, while in temperate regions control is erratic or non-existent. The invasion of giant salvinia in Louisiana offers a unique opportunity to understand the mechanisms behind this latitudinal gradient in biological control. The goal of this project is to quantify the growth rates of giant salvinia under different management scenarios along a latitudinal gradient. Potential research questions include: How can we improve the establishment and population growth of the C. salviniae in temperate regions? How will early interventions affect the dynamics of the giant salvinia? How can we integrate management approaches to reduce giant salvinia in temperate regions? The student will have direct access to several tools and facilities to conduct research including boats, growth chambers, greenhouses, research ponds, and field sites. In addition, the student will be able to incorporate several novel tools in ecological research including aerial mapping of aquatic vegetation (drones), modeling software (Netlogo), Geographical Information Systems (GIS), among others. An interdisciplinary team will be involved in this project with expertise on Biological Control, Conservation Ecology, and Aquatic Plant Management. Results from this project will be used to develop an integrated management program of giant salvinia based on region-specific conditions. Background Information: The Department of Entomology is part of LSU AgCenter located in Baton Rouge, Louisiana. The Department of Entomology was established in 1889 year and includes 16 faculty involved in applied research related to bees, mosquitos, termites, taxonomy, integrated pest management, toxicology, genetics, and insect physiology. Current research in the biological control and invasive species ecology laboratory includes the evaluation of parasitoids of emerald ash borer (Agrilus planipennis), and the biology and ecology of the crape myrtle bark scale (Acanthococcus lagerstroemiae). Located just one hour northwest of New Orleans, Baton Rouge offers plenty of entertainment for people of all ages including great food, music, art exhibits and outdoor activities. Minimum Requirements: A master degree in Entomology, Ecology, and/or Biological Control. We seek a candidate with a high standard in scientific writing and oral communication. Application: Please send a one-page letter of interest and complete CV including GPA and GRE scores to rd...@agcenter.lsu.edu. Preferred Qualifications: Experience on wetlands, ecological models, GIS, boating.
