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, Volume 40, Issue 2, Page 221-245, June 2026.
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 ...

Acquisitive root exploration strategies help maintain higher peak sap flux rates during summer drought, but more root biomass does not

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2933-2945, June 2026.
Summary Roots are responsible for soil water uptake, yet little is known about how variation in fine‐root traits relates to whole‐tree water movement, particularly during periods of drought. By combining a 3‐yr dataset monitoring sap flow rates with measures of fine‐root biomass, length, and morphology across 10 tree species, we addressed hypotheses ...

The pollination ecology and mouthpart morphology of a pollen‐feeding fly Incurviseta cf. maculifrons (Diptera: Lauxaniidae) in the Australian Alpine

open access: yesPhysiological Entomology, Volume 51, Issue 2, Page 214-225, June 2026.
The Lauxaniid fly Incurviseta cf. maculifrons (Malloch, 1925) is a locally abundant but poorly understood flower visitor in the Australian Alpine. We describe the flower visitation, pollen transport, pollen diet and mouthpart morphology of I. cf. maculifrons using field observations, pollen analyses and scanning electron microscopy. I. cf.

Macronutrient composition in pollen affects development and survival in wild bees

open access: yesPhysiological Entomology, Volume 51, Issue 2, Page 350-362, June 2026.
Small carpenter bees (Ceratina calcarata) were reared on diets formulated with black poplar and dandelion pollen, while closely monitoring developmental metrics, lipid content and survival. Macronutrient analyses on both pollen types revealed dandelion pollen contained lower levels of protein, essential amino acids and several fatty acids, which ...

Phylogenetic Diversity and Community Assembly of Vascular Plants Along Environmental Gradients in the Western Pamir–Alay: A Case Study From Surkhandarya Province, Southern Uzbekistan

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Using extensive field, herbarium, and database records, we examine patterns of species richness, phylogenetic diversity, and community assembly along elevational and climatic gradients in an understudied region of Central Asia. ABSTRACT Biodiversity plays a fundamental role in ecosystem structure, function, and stability, but its response to ...
