I study impacts of global change on forest ecosystem functions.
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.

This found orders of magnitude of differences in seed production from dry tundra to tropical rainforest beyond which can be explained by the Net Primary Production (NPP).

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.

Niche shifts from trees to fecundity to recruitment that determine species response to climate change
This paper quantified the community reorganizations from adults to fecundity to seedling recruitment.
