![]() Sink–source status of the coniferous forest remains uncertain. In the study region, our findings suggest that the deciduous broadleafįorest will likely remain an annual carbon sink, while the carbon Precipitation are to be expected under future climates during summer months If prolonged periods (weeks to months) of increased T a and reduced Periods that reduced ET at both stands, although the reduction at theĬoniferous forest was relatively larger than that of the deciduous forest. Additionally, ET was sensitive to prolonged dry Temperature ( T a), with the largest annual ET observed in the warmest years Variability inĪnnual ET at both forests was related most to the variability in annual air Reduced annual NEP values compared to the deciduous forest. However, during warm and dry years, the evergreen forest had largely Resulting in reduced annual NEP values – an impact that was more pronouncedĪt the deciduous broadleaf forest compared to the evergreen needleleafįorest. In general, warm temperatures caused higher ecosystem respiration (RE), In both stands however, the degree of response varied among the two stands. ![]() Summer meteorology greatly impacted the carbon and water fluxes Similarly, the 6-year mean annual evapotranspiration (ET) of theĬoniferous forest was higher ( 442☓3 mm yr −1) than that of theĭeciduous forest ( 388☓4 mm yr −1), but with similar interannual Slightly higher and more variable ( 218☑09 g C m −2 yr −1)Ĭompared to that of the deciduous forest NEP ( 200☘3 g C m −2 yr −1). The 6-year meanĪnnual net ecosystem productivity (NEP) of the coniferous forest was Leaf-retention and shape strategy: one stand was a deciduous broadleafįorest, while the other was an evergreen needleleaf forest. The two stands however, stand composition varied in terms of tree The geographic location, forest age, soil, and climate were similar between Temperate forests were compared over a 6-year period from 2012 to 2017. The annual carbon and water dynamics of two eastern North American
