Seed fossil record of Solanaceae revisited

TAXON, Volume 75, Issue 1, Febuary 2026.
Abstract The fossil record for Solanaceae has a complex taxonomic history, with many species originally described in the family being subsequently shown to belong in other plant families. In this work, we present an in‐depth analysis of the nightshade seed fossil record, which corresponds to the largest amount of fossil material for the family.

Scale Effect on Evapotranspiration: Predicting the Continental and Global Scale Water Balance Based on Percolation Theory and Optimality Principle

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Moisture recycling over the continents, which is known to increase with increasing spatial scale, increases both precipitation and sensible heat fluxes without increasing the overall latent heat flux, implying a reduction in evapotranspiration (ET) with increasing spatial scale. One may hypothesize that the architecture of plant/ecosystem root
