Nematology is the study of roundworms, a diverse invertebrate phylum that occurs worldwide in virtually every environment, and second only to insects in the number of species. Only about 3 percent of all species have been studied or identified and these include significant parasites of humans, animals, and plants. A primary mission of the Department of Nematology is to develop environmentally sound approaches to manage those nematodes that worldwide cause nearly eighty billion dollars annual damage to crops. Other objectives are to utilize nematodes that benefit agriculture and the environment as agents of nutrient cycling and soil fertility as well as agents for biological control of some insect pests. Additional objectives focus on nematodes as fundamental models for addressing basic biological questions in genetics, development, and molecular biology. The Department of Nematology offers graduate and postgraduate opportunities in biocontrol, ecology, genetics, molecular biology, physiology, and systematics. The Department offers specific expertise in applied nematode problems of subtropical and desert agriculture.
A graduate program in Nematology is offered within a broad biological context. Students are enrolled in a more general department or interdepartmental program which provides a core of graduate courses. The general departments may include Biology, Botany and Plant Sciences, Entomology, Plant Pathology, and Soil and Environmental Sciences; interdepartmental programs may include Environmental Toxicology or Genetics. Dissertation research opportunities, major research professor, curriculum advisor, and specific courses are provided by the Department of Nematology to complement requirements of the more general department or program.
UPPER-DIVISION COURSES
NEM 120. Soil Ecology. (4) S
Lecture, three hours; discussion, one hour. Prerequisite(s): BIOL 005A and BIOL 005B, or BIOL 002 and BIOL 003. Examination of soil biota and their relationships with plants and the soil environment. Emphasis on soil biotic interactions that influence soil fertility, plant disease, and plant growth. The importance of the different microbial and faunal groups is examined from the rhizosphere to the ecosystem level. Crowley
