Of walls and floors: how physical structures affect mating song detection in stridulating orthopterans

open access: yesEcological Entomology, Volume 51, Issue 1, Page 141-152, February 2026.
Schematic representation of the experimental settings for one field type. Each setting was assigned one of the three treatments (i.e., walls, floors, or control). Each treatment contained an AudioMoth™ (circle), either positioned close to the ground (5 cm) or elevated (60 cm), acting as a receiver organism. Abstract Sensory ecology theory proposes that

Photoperiod–Temperature Interactions in a Changing Climate: A Review of Plant Phenological Responses

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Climate change is reshaping plant phenology and species distributions, especially in temperate and boreal ecosystems, where advances in spring events have already extended the growing season. While temperature has been the primary focus of many studies, the role of photoperiod—a stable, latitude‐dependent cue—remains underexplored.
