Background The rate of CO2 uptake by photosynthesis is determined by the acclimation of leaves to the prevailing light environment. In dense forests, light intensity decreases exponentially as we go from the top of the canopy towards the ground, as light is absorbed and scattered by leaves.

Background Dynamic Global Vegetation Models (DGVMs) are key tools for understanding biosphere-climate feedbacks and transient vegetation dynamics in response to global change. A novel vegetation demography model, the BiomeE, is a mechanistic cohort-based model which simulates vegetation dynamics and biogeochemical processes.

Background The gross primary production (GPP) of an ecosystem, that is, the carbon it assimilates via photosynthesis, differs strongly from one year to the next. This variability between years is called the interannual variability (IAV) of GPP and the reasons for why GPP can change substantially from year to year are unclear.

Supervision: Dr. Laura Marques and Prof. Benjamin Stocker Background Climate warming is driving an advance of leaf unfolding in trees, promoting longer growing seasons. However, the advance of the start-of-the-season (SOS) can induce false springs, i.

Supervision: Dr. Koen Hufkens and Prof. Benjamin Stocker We call on students to determine the importance of topographic and soil factors on natural vegetative landscape components (forest cover fraction, vegetation height, woody fraction).
