Overcoming environmental constraints to high‐yielding eastern cottonwood productivity in the southeastern United States

open access: yesAnnals of Applied Biology, EarlyView.
The rising demand for biomass highlights Populus deltoides as a productive woody species. A 6‐year study in Sumter County, SC, assessed the effects of irrigation, fertilization, and clonal variation on growth and productivity. Eight clones were studied under two irrigation levels (33 and 1500 kPa) and nutrient rates (high: up to 182 kg N ha−1; low: 50%

Host plant richness and abundance drive populations of a super‐generalist xylem‐feeding insect

open access: yesEcological Entomology, EarlyView.
Philaenus spumarius abundance was assessed across 93 sites and four habitat types (olive groves, vineyards, meadows, and field margins) within eight heterogeneous agricultural landscapes over the year. In spring, nymph abundance was positively associated with herbaceous plant species richness and vegetation cover, highlighting that even super ...

Human Disturbance but Not Predation Risk Is Associated With Increased Vigilance in Roe Deer

open access: yesEthology, EarlyView.
Roe deer vigilance is lower in natural than in modified habitats, decreases with group size, but is not significantly influenced by stable wolf presence, suggesting habitat‐driven risk perception and reliance on spatial avoidance over increased alertness.

Shrubs and trees as natural insect protection for grazing animals in Switzerland and the alpine region: A systematic review of in vitro, in vivo and clinical trials Sträucher und Bäume als natürlicher Insektenschutz für Weidetiere in der Schweiz und im Alpenraum: Eine systematische Literaturübersicht über in vitro‐, in vivo‐ und klinische Studien

open access: yesMedical and Veterinary Entomology, EarlyView.
Biting or irritating insects are a threat to the health and welfare of grazing animals. This systematic review reveals that several shrubs and bushes growing in the alpine area have insecticidal, insect‐repellent and/or attractant properties. The alder Alnus glutinosa, juniper Juniperus communis, spruce Picea abies and walnut Juglans regia are ...

Shaping future forests: how can ecophysiology support climate‐smart forest management?

open access: yesNew Phytologist, EarlyView.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...
