TLDR
Investigation of relationships between phenology and productivity in temperate and boreal forests finds the productivity of evergreen needleleaf forests is less sensitive to phenology than is productivity of deciduous broadleaf forests, which has implications for how climate change may drive shifts in competition within mixed-species stands.Abstract:
We use eddy covariance measurements of net ecosystem productivity (NEP) from 21 FLUXNET sites (153 site-years of data) to investigate relationships between phenology and productivity (in terms of both NEP and gross ecosystem photosynthesis, GEP) in temperate and boreal forests. Results are used to evaluate the plausibility of four different conceptual models. Phenological indicators were derived from the eddy covariance time series, and from remote sensing and models. We examine spatial patterns (across sites) and temporal patterns (across years); an important conclusion is that it is likely that neither of these accurately represents how productivity will respond to future phenological shifts resulting from ongoing climate change. 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. Finally, the productivity of evergreen needleleaf forests is less sensitive to phenology than is productivity of deciduous broadleaf forests. This has implications for how climate change may drive shifts in competition within mixed-species stands.read more

Inner Mongolian grassland plant phenological changes and their climatic drivers
TL;DR: It is inferred that plant phenologies can divergently response to current global warming (depending on the seasonal patterns of warming) and other influential factors such as precipitation and the interactions between the timings of different phenological stages are also needed in predicting the phenological dynamics.

Evaluation of the Quality of NDVI3g Dataset against Collection 6 MODIS NDVI in Central Europe between 2000 and 2013
TL;DR: The results showed that the original NDVI3g has limited applicability in Central Europe, which was implied by the significant disagreement between the ND VI3g and MODIS NDVI datasets; the harmonization of NDVI2g with MODISNDVI is promising since the newly created dataset showed improved quality for diverse vegetation metrics.

TL;DR: The MexFlux network as discussed by the authors was proposed to measure the surface-atmosphere exchange of heat and greenhouse gases in Mexico, and the goal of the network is to improve our understanding of how climate variability and environmental change influence the dynamics of Mexican ecosystems.

Increased plant growth in the northern high latitudes from 1981 to 1991
TL;DR: In this paper, the authors present evidence from satellite data that the photosynthetic activity of terrestrial vegetation increased from 1981 to 1991 in a manner that is suggestive of an increase in plant growth associated with a lengthening of the active growing season.

TL;DR: In this paper, the authors analyse the effect of extrapolation of night-time values of ecosystem respiration into the daytime; this is usually done with a temperature response function that is derived from long-term data sets.
