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

Fern spore dispersal: A methodological review and experimental field study

open access: yesApplications in Plant Sciences, Volume 14, Issue 1, January-February 2026.
Abstract Spore dispersal is one of the most important but perhaps the least investigated and understood processes in determining the geographical distribution of fern species. After a methodological review of the aerobiology of fern spores, we examined the impact of spore characteristics and meteorological factors on their airborne dispersal.

Habitat‐Based Predictions of Bridle Shiner (Notropis bifrenatus) in the Northeastern United States

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
We developed local and regional models for Maine and New Hampshire that may be used to focus bridle shiner (Notropis bifrenatus) surveys on areas with high predicted habitat suitability. This is significant because bridle shiners receive protection or concern status in thirteen states and two Canadian provinces: Limited data show that bridle shiners ...
