T model – a simple carbon allocation model for tree growth. Two case studies for both high and low [CO2]. By Li Guangqi (Macquarie University)

Tree ring width is one of the most important materials for past climate reconstruction. However, “divergence” problem (correlation strength between temperature and ring width breaks where temperature was conferred as the limiting factors in high elevation and high latitude regions and ring width data are previously applied for temperatures) challenges the classical dendrochronology principle of … Continue reading T model – a simple carbon allocation model for tree growth.

How plants take heat from the environment? By Ning Dong

The leaves interact with the above physical environment in two ways: energy & mass exchange. From the biophysical control aspect, leaves can maintain their temperatures within a narrower range than ambient temperatures, which can be predicted by leaf energy balance theory. We present and predict the existence of crossover temperature by field observation (Fig.1 & … Continue reading How plants take heat from the environment? By Ning Dong

The Fertility Question: How do soil nutrients influence the carbon cycle? By Beni Stocker

A general notion of “soil fertility” is commonly left unaccounted for in models of the terrestrial biosphere and has received relatively little attention in carbon cycle science. This changed since the presentation of results by Vicca et al. (2012) and Fernandez-Martinez et al. (2014). Using data from forests around the globe where gross primary productivity … Continue reading The Fertility Question: How do soil nutrients influence the carbon cycle? By Beni Stocker
