Prey and prejudice: predation by the European bee‐eater Merops apiaster has species‐specific effects on the ecology and genetics of bumblebees

open access: yesOikos, EarlyView.
Predation is a major ecological force, but its effect on bees has rarely been studied. Here, we investigated whether the presence of the European bee‐eater Merops apiaster, a migratory bird species and major bee predator, decreases the abundance and body size of three common bumblebee species (Bombus lapidarius, B. terrestris and B.

A Flexible and Stretchable Triboelectric Nanogenerator with Agarose/P(HEA‐co‐AA)‐Al/NaCl Electrodes for Bio‐Mechanical Energy Harvesting and Fall Detection

open access: yesChemistryOpen, EarlyView.
A double‐network (DN) conductive hydrogel (APA‐hydrogel) was synthesized using NaCl‐coordinated agarose and poly (2‐hydroxyethyl acrylate‐co‐acrylic acid). Applied as a triboelectric nanogenerator (APA‐TENG), it achieved 900 V open‐circuit voltage, 73.42 μA short‐circuit current, and 3.52 mW peak power. APA‐TENG holds promise for energy harvesting, low‐
