The relationship between maturation size and maximum tree size from tropical to boreal climates
The fundamental trade-off between current and future reproduction has long been considered to result in a tendency for species that can …

Remotely sensed crown nutrient concentrations modulate forest reproduction across the contiguous United States
This paper reveals the effects of remotely sensed nutrient supply on forest reproduction across the United States. Consistent with our previous findings, we found increasing phosphorous is assocaited with low seed production at both species and landscape level.

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.
