Masting is uncommon in trees that depend on mutualist dispersers in the context of global climate and fertility gradients
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.

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.
