Abstract. Accurately representing the response of ecosystems to environmental change in land surface models (LSMs) is crucial making accurate predictions future climate. Many LSMs do not correctly capture plant respiration and growth fluxes, particularly extreme climatic events. This part due unrealistic assumption that total carbon expenditure (PCE) always equal gross accumulation by photosynthesis. We present evaluate a simple model labile storage utilisation (SUGAR) designed be integrated...
Abstract Understanding the response of plant respiration to climate change is key determining whether global land carbon sink continues into future or declines. Most vegetation models use a classical growth-maintenance approach, which predicts that nocturnal controlled by temperature only. However, recently published observations show decline through night even at constant temperature, these cannot reproduce. Here we assess role respiratory substrates in this observed evaluating an...
'…there are trade-offs associated with the LES that we just beginning to understand. The work presented here by Asao et al. fills in yet another piece of jigsaw will ultimately allow us predict plant functional dynamics at a global scale.' role nonstructural carbohydrates accurate predictions ecosystem carbon fluxes is becoming increasingly apparent. Over long term, NSCs represent buffer against reductions photosynthesis often occur during climate extremes (Dietze al., 2014). Representing...
Abstract. Reliable estimates of soil carbon change are required to determine the budgets consistent with Paris Agreement climate targets. This study evaluates projections during 21st century in Coupled Model Intercomparison Project Phase 6 (CMIP6) Earth system models (ESMs) under a range atmospheric composition scenarios. In general, we find reduced spread changes global (ΔCs) CMIP6 compared previous CMIP5 model generation. However, similar reductions were not seen derived contributions ΔCs...
Abstract Vegetation and precipitation are known to fundamentally influence each other. However, this interdependence is not fully represented in climate models because the characteristics of land surface (canopy) conductance water vapor CO 2 determined independently precipitation. Working within a coupled atmosphere modelling framework (CAM6/CLM5; Community Atmosphere Model v6/Community Land v5), we have developed new theoretical approach characterizing by explicitly linking its dynamic...

Accurate representations of stomatal conductance are required to predict the effects climate change on terrestrial ecosystems. Stomatal optimisation theory, idea that plants have evolved maximise carbon gain under certain constraints, such as minimising water loss or preventing hydraulic damage, is a powerful approach representing behaviour bypasses need represent complex physiological processes. However, while their ability replicate observed responses promising, models often present...
The observed increase in forest productivity over the industrial period is largely attributed to a stimulation of photosynthesis by increasing atmospheric CO2 concentrations. extent which this fertilisation effect will persist future, however, uncertain as competing limitations such availability nutrients and soil moisture may prevent plants from making use carbon they assimilate, dominate future response.Many early studies simulations that make classical ‘big-leaf’...
