Long Term Research in Environmental Biology

Funds data series long enough to answer questions a normal grant cycle cannot reach β€” decades of ecology, evolution and ecosystem measurement.

OpenNational Science FoundationUnited States

Some questions in environmental biology cannot be answered inside a three-year grant. Selection acting on a population, organisms whose generations turn over slowly, soil nutrient pools, climate cycles with long return intervals β€” all of it needs a record longer than a normal award.

LTREB pays for that record. It funds the generation of extended time series in evolutionary biology, ecology and ec…

Extended time series in evolutionary biology, ecology and ecosystem science β€” selection and other evolutionary processes over time, interspecific interactions varying across time and space, slow-turnover populations, eco-evolutionary feedbacks, intermediate and long-term material pools such as soil nutrients, and long-return-interval climate forcing. Marine ecology goes to Biological Oceanography; marine evolutionary dynamics is accepted here.
