Plant phenology—the timing of cyclic or recurrent biological events in plants—offers insight into the ecology, evolution, and seasonality of plant-mediated ecosystem processes. Traditionally studied phenologies are readily apparent, such as… More
The AmeriFlux network aims to ensure the availability of continuous, long-term ecosystem measurements necessary to build effective models and multisite syntheses, as well as provide immediate insights. AmeriFlux sites span… More
Understanding tree transpiration variability is vital for assessing ecosystem water-use efficiency and forest health amid climate change, yet most landscape-level measurements do not differentiate individual trees. Using canopy temperature data… More
Wetlands are an important component of the New England landscape, the Harvard Forest has its share; about 25% of the landscape is classified wetland or very poorly drained. Read how the The AmeriFlux instrument loaner program was used for a new pilot study at Harvard Forest.
Climate change is affecting the phenology of terrestrial ecosystems. In deciduous forests, phenology in leaf area index (LAI) is the primary driver of seasonal variation in the fraction of absorbed… More
Linking biometric measurements of stand-level biomass growth to tower-based measurements of carbon uptake—gross primary productivity and net ecosystem productivity—has been the focus of numerous ecosystem-level studies aimed to better understand… More

What happens when the dominant tree species in a forest is killed off by an insect pest? Eastern hemlock (Tsuga canadensis) is considered a foundation species with a range spanning… More
Last year, the AmeriFlux database hit a big milestone: 3000 years of site data in our half-hourly Flux/Met data (BASE) product! This achievement is a great testament to the collaboration… More
Climate extremes such as heat waves and droughts are projected to occur more Frequently with increasing temperature and an intensified hydrological cycle. It is Important to understand and quantify how… More
