Introgression despite minimal hybridization: mating system modulates phenotypic associations with introgression in Clarkia

New Phytologist, Volume 250, Issue 4, Page 2619-2633, May 2026.
Summary Secondary contact between incipient species provides the opportunity to understand how trait divergence restricts gene flow. While mating system transitions are particularly common and involve a suite of phenotypic changes, the extent to which these changes influence gene flow during speciation is poorly understood.

Field Observations Validate LES‐Derived Scaling of Vertical‐Velocity Variance During the Afternoon Transition of the Convective Boundary Layer

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The convective velocity scale is commonly used to describe the vertical‐velocity variance in the convective boundary layer driven by surface heating, and is valid when the surface heat flux varies slowly compared to the eddy turnover time. This quasi‐equilibrium assumption typically holds from late morning to early afternoon, but breaks down ...
