Tree Fecundity and forest regeneration

Using nearly 2.9 million tree-years from 292 species, this paper shows that slope, aspect, and drainage shape tree fecundity and interact with climate, suggesting that topographically diverse landscapes can offer local refuges for reproduction under climate change.

Across 292 tree species in North America and Europe, this paper shows that changes in seed production are driven by moisture deficits and late freeze rather than rising annual temperature, so tree fecundity is not yet shifting poleward despite rapid warming.

This paper reveals the impact of late freeze impacts on tree fecundity across North America and Europe. This is also the first time we are able to make continental-scale predictions through the MASTIF network

The fundamental trade-off between current and future reproduction has long been considered to result in a tendency for species that can …

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.

This paper quantifies three components of masting (volatility, periodicity, and synchronicity) from 12 million tree-years worldwide and shows that species dependent on mutualist dispersers avoid masting, an effect that explains more variation than climate, soil fertility, or nutrient demand.

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

This paper confirmed the seed number-size trade-off across the trait spectrum based on the Species Seed Production (SSP) developed in Qiu et al. (2022), Nature Communications

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.

The 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.

This paper quantified the community reorganizations from adults to fecundity to seedling recruitment.

Tong will talk about phenology impacts on tree fecundity

The timing of spring green-up affects tree reproduction in the temperate and boreal forests.
