Mitigating Drought Effects on Grasslands: The Potential of Different Seed Mixtures to Optimize Water Use Efficiency

open access: yesEcohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT Grassland response to changes in water availability is closely tied to the traits of the plant community. Plants can adopt either moderate and efficient (conservative) or rapid and demanding (acquisitive) resource use strategies. These strategies combined with the plant interactions with microbes, such as arbuscular mycorrhiza fungi (AMF ...

Homo luzonensis and the role of homoplasy in the morphology of hominin insular species

open access: yesCladistics, Volume 42, Issue 3, Page 286-316, June 2026.
Abstract Homo luzonensis lived during the upper Pleistocene in the northern Philippines, east of the Wallace line. The few specimens attributed to this species show a mosaic of plesiomorphies for the genus Homo and apomorphies found in upper Pleistocene Homo species.

Increased arbuscular mycorrhizal fungal biomass and diversity in soil under long‐term climate drying and warming

open access: yesNew Phytologist, Volume 250, Issue 6, Page 3961-3975, June 2026.
Summary Arbuscular mycorrhizal fungi (AMF) support critical ecosystem services including plant resource acquisition and productivity. AMF functional traits such as relative biomass investment in root vs soil colonization or drought tolerance are thought to be evolutionarily conserved within AMF lineages and might influence AMF community responses to ...

Grassland age and local adaptation shape drought resilience across semi‐natural grassland populations

open access: yesNew Phytologist, Volume 250, Issue 6, Page 3646-3660, June 2026.
Field sampling sites and mesocosm experimental design. Summary Increasing frequency and intensity of droughts threaten grassland ecosystems. Semi‐natural grasslands vary in age from ancient to younger sites established on former arable land. While species richness and composition are known to affect drought resilience, little is known about how ...
