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

Cascading Effects of Biological Invasion and Nutriment Enrichment Disrupt Freshwater Trophic Energy Pathways and Food Web Quality

open access: yesFreshwater Biology, Volume 70, Issue 11, November 2025.
ABSTRACT Freshwater ecosystems are globally threatened by multiple climatic and anthropogenic stressors, including facilitated biological invasion and eutrophication, and thus understanding their effects on ecosystem function is critical. One key aspect is the availability of long‐chain polyunsaturated fatty acids (LC‐PUFAs), which are essential for ...

Tissue humidity and pH as important species traits regulating tree methane emissions in floodplain wetland forests

open access: yesNew Phytologist, Volume 248, Issue 4, Page 1713-1727, November 2025.
Summary Despite the increasing number of studies investigating tree methane fluxes, the relationships between tree methane fluxes and species traits remain mostly unexplored. We measured leaf and stem methane fluxes of five tree species (Acer saccharinum, Fraxinus nigra, Ulmus americana, Salix nigra, and Populus spp.) in the floodplain of Lake St ...

Modelling the Spatio‐Temporal Effects of Water Level Control in an Agricultural Collector Ditch Network

open access: yesIrrigation and Drainage, Volume 74, Issue 4, Page 1717-1729, October 2025.
ABSTRACT The study focused on modelling open channel flow in an agricultural ditch network. The objectives were (1) to set up a computational tool to explore the hydraulic impacts of water level control in a collector ditch network and (2) to test the effects of damming height and ditch flow resistance on the water level and its relation to field ...
