Publications 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. Tong Qiu, James S. Clark, Kyle R. Kovach, Philip A. Townsend, Jennifer J. Swenson Cite Project DOI pdf 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.

This paper compared the volatility metrics introduced by Qiu et al., (2023) Nature Plants and compared it with traditional metrics that measures masting M.

The paper also reveals the effects of soil fertility on both individual and community fecundity at a global scale.

Valentin Journe, Benoit Courbaud, Georges Kunstler, Tong Qiu, other 95 contributors, James S. Clark Cite Project DOI pdf 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.
