Limits to reproduction and seed size-number trade-offs that shape forest dominance and future recovery
This paper aims to understand the size-numbers trade-off in species seed production and how species traits have mediate the trade-off. The paper also reveals the effects of soil fertility on both individual and community fecundity at a global scale.

Is there tree senescence? The fecundity evidence
A global analysis finds that fecundity decline in large trees is pervasive, consistent with physiological decline, thus providing new evidence for tree senescence. For the 20% of species not showing fecundity declines, this lack of evidence was linked not to specific species groups, but rather to lack of large trees in the data.

Understanding the continuous phenological development at a daily time step with a Bayesian hierarchical space-time model: impacts of climate change and extreme weathers
We developed a model to quantify how daily phenological development responds to climate change and extreme weather eventts.

Urbanization and climate change jointly shift land surface phenology in the northern mid-latitude large cities
We found that amplitude of urbanization, quantified as changes of %ISA, can compensate the negative effects (delayed SOS or advanced EOS) and amplify the positive effects (earlier SOS or later EOS) of climate change on temporal variations of LSP in most climate zones (except the dry climate)
