The tropics is the nexus for many of the remaining gaps in our knowledge of environmental
science, including the carbon cycle and atmospheric chemistry, with dire consequences for …

Many of the key processes represented in global terrestrial carbon models remain largely
unconstrained. For instance, plant allocation patterns and residence times of carbon pools …

Plants in Mediterranean ecosystems face multiple environmental stresses during the
growing season. Such stresses greatly affect ecosystem function, but are poorly represented …

The seasonality of solar irradiance and precipitation may regulate seasonal variations in
tropical forests carbon cycling. Controversy remains over their importance as drivers of …

Vegetation nutrient limitation is essential for understanding ecosystem responses to global
change. In particular, leaf nitrogen (N) is known to be plastic under changed nutrient …

Trees partition biomass in response to resource limitation and physiological activity. It is
presumed that these strategies evolved to optimize some measure of fitness. If the …

Inter-annual variations in the tropical land carbon (C) balance are a dominant component of
the global atmospheric CO 2 growth rate. Currently, the lack of quantitative knowledge on …

Existing dynamic global vegetation models (DGVMs) have a limited ability in reproducing
phenology and decadal dynamics of vegetation greenness as observed by satellites. These …

Plant phenology plays a fundamental role in land–atmosphere interactions, and its
variability and variations are an indicator of climate and environmental changes. For this …

Phenology is essential to our understanding of biogeochemical cycles and the climate
system. We develop a global mechanistic model of leaf phenology based on the hypothesis …
