Local habitat, not landscape diversity, drives richness and reproduction of cavity‐nesting bees and wasps in agricultural landscapes

Insect Conservation and Diversity, EarlyView.
Local habitat type and hedgerow cover strongly shape bee and wasp richness, but only weakly their reproductive output, outweighing the landscape diversity effects at the 1‐km2 scale. Forests host more wasp but fewer bee species, whereas orchards support high richness of both; bee reproduction patterns are driven by one dominant species, while wasp ...

First Detailed Record of Jikradia olitoria (Hemiptera: Cicadellidae) in the Swiss Southern Alps and Evaluation of Its Current Potential as a Vector of 16SrV‐Phytoplasmas

Journal of Applied Entomology, EarlyView.
ABSTRACT Jikradia olitoria Say is a Nearctic leafhopper that was recently reported in several European countries. Given its role as the vector of phytoplasmas associated with Grapevine Yellows diseases (GYD) in its native range, its presence in European vineyard agroecosystems could represent an important phytosanitary risk.

First Report on the Phytochemical and Pharmacological Properties of Hedysarum yilmazunalii

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Hedysarum yilmazunalii was collected from Erzincan, Türkiye. The leaf, stem, and root parts were then used for methanolic extraction. The extracts were analyzed for their phytochemical composition by LC–MS/MS and tested for antioxidant, enzyme inhibitory, and antiproliferative activities.

Does Working in a Hazelnut Processing Factory Increase the Risk of Hazel Pollen and Nut Sensitivity?

Allergology International, 2005
Background: Hazelnut has been reported to be one of the most important food allergens. We set out to study whether exposure to hazelnut allergen by occupational contact increases hazel pollen and hazelnut sensitivity and causes workplace-related allergic

First report of Cryptosporiopsis tarraconensis causing leaf lesion of Corylus avellana in Central Europe (Poland)

Annals of Forest Science
Key message As a result of our research, we determined that Cryptosporiopsis tarraconensis—as a new species for Central Europe—is the causative agent of leaf lesions in natural populations of hazel (Corylus avellana). Until now, this species had not been

Landscape distribution and habitat use of sika deer using indirect signs of deer activity: a simple tool for forest managers

Wildlife Biology, Volume 2026, Issue 5, September 2026.
The populations of many deer species across Europe are widely reported to be increasing, leading to potentially greater impacts on forest ecosystems. Our understanding of factors driving the regional distribution (e.g. 1 km2 resolution) of deer populations is, however, often limited by a lack of knowledge of where deer are within the landscape.
