A hybrid biometric-modelling approach for estimating carbon stock and flux indicators from tree-ring data

Reliable projections of future carbon (C) dynamics are essential to resource management decision making under a changing climate. A hybrid-biometric modelling approach that combines tree-ring based stand reconstruction and the Carbon Budget Model of the Canadian Forest Sector (CBM-CFS3) to estimate past magnitude and inter-annual variation of ecosystem carbon stocks and fluxes including net primary production (NPP), net ecosystem production (NEP), and heterotrophic respiration (Rh) can be used to generate additional corroborative data that may reduce uncertainty in C flux estimates.

Contrasting impacts of climate warming on Himalayan hemlock (Tsuga dumosa) growth: seasonal and elevational variations

Ongoing climate change can have varying impacts on tree growth within the growing season and across their elevation ranges, with important implications for forest ecosystem functions and services. However, our knowledge of these effects on climate-sensitive Himalayan forests is still limited. Here, we explore the elevational changes in climatic factors driving long-term changes in the radial growth of Himalayan hemlock (Tsuga dumosa), including recent responses to unprecedented climate warming in the central Himalayas.
