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

TL;DR: In this paper , the leaf and wood phenological events of silver birch (Betula pendula) at four different sites in Ås, southeastern Norway were investigated over four consecutive years (from 2017 to 2020), with a particular focus on 2018, a year in which there was a severe summer drought and the next year, 2019, which featured more normal conditions.

Climate change: potential implications for Ireland’s biodiversity
TL;DR: The synthesis revealed evidence of a trend towards earlier spring activity of plants, birds, and insects which may result in a change in ecosystem function and the need for biodiversity conservation plans to factor climate change into future designs.

Direct and Lagged Effects of Extreme Warm Temperatures on Forest Phenology in Europe using Envisat Meris Terrestrial Chlorophyll Index (MTCI) Time Series Data
TL;DR: In this article, the role of temperature to vegetation phenology in Europe is discussed. But the authors focus on the extreme warm seasons in Europe and do not consider the extreme cold seasons.

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.
