  • Title: Standardized flux seasonality metrics: a companion dataset for FLUXNET annual product
  • Phenological events are integrative and sensitive indicators of ecosystem processes that respond to climate, water and nutrient availability, disturbance, and environmental change. The seasonality of ecosystem processes, including biogeochemical flux (read full)

  • Title: Multi‐Decadal Carbon Cycle Measurements Indicate Resistance to External Drivers of Change at the Howland Forest AmeriFlux Site.
  • A long-standing goal of ecology has been to understand the cycling of carbon in forests. This has taken on new urgency with the need to address a rapidly changing climate. Forests serve as long-term stores for atmospheric CO2, but their continued abi (read full)

  • Title: Heterotrophic respiration and the divergence of productivity and carbon sequestration
  • Net primary productivity (NPP) and net ecosystem production (NEP) are often used interchangeably, as their difference, heterotrophic respiration (soil heterotrophic CO2 efflux, RSH = NPP−NEP), is assumed a near-fixed fraction of NPP. Here, we show, (read full)

  • Title: Disturbance-accelerated succession increases the production of a temperate forest
  • Many secondary deciduous forests of eastern North America are approaching a transition in which maturing early successional tree species are declining, resulting in an uncertain future for this century-long carbon (C) sink. We initiated the Forest Ac (read full)

  • Title: Water Availability Impacts on Evapotranspiration Partitioning
  • Knowing how evapotranspiration (ET) is mediated by abiotic and biotic pathways is essential to understanding how water affects ecosystem productivity. Recent studies have investigated the average transpiration fraction (T/ET) across sites and biomes, (read full)

  • Title: On the inter- and intra-annual variability of ecosystem evapotranspiration and water use efficiency of an oak savanna and annual grassland subjected to booms and busts in rainfall
  • Whether annual evapotranspiration of native ecosystems is increasing or decreasing with time as CO2 concentrations are rising, the climate is warming and rainfall experiences booms and busts, remains an unanswered question in the field of global cha (read full)

  • Title: Carbon Budget Of The Harvard Forest Long‐Term Ecological Research Site: Pattern, Process, And Response To Global Change
  • How, where, and why carbon (C) moves into and out of an ecosystem through time are long‐standing questions in biogeochemistry. Here, we bring together hundreds of thousands of C‐cycle observations at the Harvard Forest in central Massachusetts, U (read full)

  • Title: Plant-mediated methane transport in emergent and floating-leaved species of a temperate freshwater mineral-soil wetland
  • Methane flux from freshwater mineral-soil (FWMS) wetlands and its variability among sites is largely modulated by plant-mediated transport. However, plant-mediated transport processes are rarely resolved in land surface models and are poorly parametr (read full)

  • Title: Outgoing Near-Infrared Radiation From Vegetation Scales With Canopy Photosynthesis Across a Spectrum of Function, Structure, Physiological Capacity, and Weather
  • We test the relationship between canopy photosynthesis and reflected near-infrared radiation from vegetation across a range of functional (photosynthetic pathway and capacity) and structural conditions (leaf area index, fraction of green and dead lea (read full)

  • Title: Long-term carbon flux and balance in managed and natural coastal forested wetlands of the Southeastern USA
  • Wetlands store large C stocks and play important roles in biogeochemical C cycling. However, the effects of environmental and anthropogenic pressures on C dynamics in lower coastal plain forested wetlands in southern U.S. are not well understood. We (read full)
