Long Term Research in Environmental Biology
About NSF's Long Term Research in Environmental Biology Program
The Long-Term Research in Environmental Biology (LTREB) Program supports extended time-series data that address questions in evolutionary biology, ecology and ecosystem science.
Research areas include natural selection and other evolutionary processes and their effects on populations, communities, and ecosystems; species interactions that vary over time and space; population and community dynamics of species with long life spans and slow reproductive cycles; feedbacks among ecological and evolutionary processes; nutrients in soils that change over long periods of time; and climate cycles that take place over long intervals.
