Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.

Mechanisms of Body Alignment in a Diurnal Songbird Migrant

Ethology, EarlyView.
The graphical abstract illustrates the body alignment mechanism of a diurnal songbird migrant, the dunnock (Prunella modularis). Dunnocks consistently expressed an angular body alignment, with inter‐individual variation at the level of the population.

A protracted phenology: Post‐diapause larval development of a threatened butterfly

Insect Conservation and Diversity, EarlyView.
Larval survival during diapause was high; hibernaculum webs were mostly located near Succisa pratensis plants, which often retained vital leaves through winter. Post‐diapause developmental time varied strongly depending on exposure to different microclimates, being reduced by litter cover, solar radiation and a higher heat load index.
