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

Effect of equisetum arvense extract on bone mineral density in Wistar rats via digital radiography

open access: yesCaspian Journal of Internal Medicine, 2019
Background: Osteoporosis is a common disease of old age. The present study used digital radiography to determine the effects of equisetum arvense extract on the bone mineral density (BMD) of experimental rats. Methods: In this experimental study, 25 male

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 ...

Grow With the Flow? Impact of Experimental Floods on Riparian Vegetation in an Alpine River

open access: yesRiver Research and Applications, Volume 42, Issue 1, Page 162-175, January 2026.
ABSTRACT Experimental floods have been proposed as a measure to mitigate effects of river flow regulation, primarily vegetation encroachment, streambed colmation, and loss of bed and channel mobility. In this study, we investigated the short‐ and long‐term biogeomorphic effects of an experimental flood programme conducted in the Spöl River (Swiss Alps)
