In temperate and boreal ecosystems, phenological transitions (particularly the timing of spring onset and autumn senescence) are known to represent a major control on spatial and temporal variation in forest carbon sequestration. To investigate these patterns, we analyzed 153 site-years of data from the FLUXNET &39;La Thuile&39; database. Title : Influence of spring and autumn phenological transitions on forest ecosystem productivity: Language : English: Author, co-author : Richardson, A. In spring and autumn, increased GEP resulting from an ‘extra’ day tends to be offset by concurrent, but smaller, increases in ecosystem respiration, and thus the effect on NEP is still positive. Spring productivity anomalies appear to have carry-over effects that translate to productivity anomalies in the following autumn, but it is not clear that these result directly from phenological anomalies. , Kramer 1994, influence Estrella and Menzel, Cleland et al.

Indeed, reducing uncertainty in phenology models is a crucial issue allowing more reliable predictions on how climate change may influence the length of the vegetation period and thus ecosystem productivity and its late frost susceptibility (e.

,. In a ‘normal’ year, physiological activity ramps up in spring, levels off in early summer and influence of spring and autumn phenological transitions on forest ecosystem productivity. begins to taper off influence of spring and autumn phenological transitions on forest ecosystem productivity. by mid-summer before declining rapidly with autumn senescence. DC Field Value Language; dc. Richardson AD, influence of spring and autumn phenological transitions on forest ecosystem productivity. Black TA, Ciais P, Delbart N, Friedl MA, Gobron N et al. We investigated this hypothesis using four spring onset phenological indicators in conjunction with surface–atmosphere CO 2 exchange data from the conifer-dominated Howland Forest and deciduous-dominated Harvard Forest AmeriFlux sites. As a result, primary productivity of temperate forests is expected to increase, with each day advance in spring leaf-out translating to an increase in net carbon uptake influence of spring and autumn phenological transitions on forest ecosystem productivity. of 45 kg carbon per hectare forest and each day delay in autumn senescence translating to an increase of 98 kg ha −1.
