Threshold Regression for Fixed‐T$$ T $$ Panel Data with Interactive Fixed Effects

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper develops a new toolbox for estimation and inference in panel data threshold regression models with interactive fixed effects and a fixed number of time periods, T$$ T $$. The toolbox is designed to be simple, accurate, and computationally efficient.

Climate Shapes Elevational Gradients in Concentration, Composition, and Functional Diversity of Willow Metabolomes

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plants produce broad spectra of metabolites comprising primary metabolites involved in core physiological processes and specialized metabolites mediating responses to biotic and abiotic stress. Understanding how these various components of the metabolome respond to different environmental pressures can help us to understand drivers of ...

Floral adaptation and modular trait evolution associated with a shift from bee to hummingbird pollination

open access: yesPlant Biology, EarlyView.
By comparing floral trait variation, integration and modularity in two sister species of Neotropical Costus with a pollination shift, we show that, despite pollination syndrome divergence, both species exhibit low floral variation and functional modularity, consistent with pollinator‐driven selection on traits mediating pollen transfer efficiency and ...
