Systematic and Population Biology


Population Biology

This program focuses on measures of population properties and understanding processes that lead to variation within and between populations. Approaches include empirical and theoretical studies of population structure and dynamics, microevolution, organismal adaptation, geographical differentiation, natural hybridization, and speciation, and processes that lead to macroevolutionary patterns of trait evolution. Research areas include:

* Population Ecology: Studies of single species from an ecological and evolutionary perspective including: life history and life cycle phenomena of terrestrial, freshwater, and wetland organisms; demography of age- and stage-structured populations; population dynamics including linear, nonlinear, and stochastic approaches; patterns of natural and sexual selection.

* Evolutionary Genetics: Studies of the causes and consequences of variation, change, selection, and evolution of biochemical characteristics, RNA and DNA sequences, mobile elements, and genic organization and function; the evolution of genetic architecture; evolutionary genomics; population and quantitative genetics.

* Evolution of Phenotypes: Studies of how the properties of genes (number, arrangement, and pattern) and their interactions, including epigenetics and development, determine evolutionary processes; how micro- and macro-evolutionary processes explain the evolution of complex phenotypes.

Other programs within NSF also support research addressing aspects of ecology and evolutionary biology. Such studies focusing on organism-centered analyses of physiology, morphology, behavior, or development should be directed to programs in the Division of Integrative Biology and Neuroscience. Studies focusing on marine organisms should be directed to the Biological Oceanography Program in the Division of Ocean Sciences. Studies focusing on interactions among species should be directed to the Ecology Program. Interdisciplinary studies are welcome.

    Target Dates: January 9 and July 9 (annually)
