Effect of cool season turfgrass mixtures and mycorrhizal inoculation at establishment to sequential acute droughts under field conditions

open access: yesCrop Science, Volume 65, Issue 6, November/December 2025.
Abstract Turfgrass species mixtures are often recommended over the use of single species due to greater genetic diversity to meet broader landscape needs. However, the intended composition of the mixture can change over time due to rates, contrasting tolerance to environmental stresses, and management practices. Strategies used to increase tolerance to

Metabarcoding Reveals Fine Scale Patterns of Trophic Resource Use and Partitioning Along Gradients of Land Use and Deer Density in a Multi‐Species Ungulate Community

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We used DNA metabarcoding of 2,568 fecal samples to examine seasonal diets and resource partitioning among four deer species (moose, roe deer, red deer, fallow deer) across two Swedish landscapes. Deer consumed a wide range of plants, but diets were typically dominated by a few key taxa, with distinct dietary separation between moose and smaller deer ...

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration

open access: yesPlant-Environment Interactions, Volume 6, Issue 5, October 2025.
Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐
