Diurnal Variations in Photochemical Energy Utilization and Osmotic Adjustments in Black Poplar Leaves Under Progressive Water Stress

open access: yesPlant, Cell &Environment, Volume 49, Issue 10, Page 7590-7603, October 2026.
ABSTRACT Drought limits the productivity of fast‐growing woody crops, although the metabolic adjustments conferring water stress tolerance remain poorly understood. We investigated the responses of Populus nigra seedlings to water stress by integrating daily physiological measurements and NMR metabolomic analyses.

Alley cropping opportunities and research priorities in orchard systems: A case study in northern California

open access: yesAgronomy Journal, Volume 118, Issue 5, September/October 2026.
Abstract Alley cropping is the production of annual and perennial cash crops between orchard trees. Despite its documented benefits, adoption of alley cropping in California remains limited. This paper describes a long‐term commercial alley cropping system in northern California and identifies research areas that can support this practice.

The art of avoidance: bedsite use, antipredator strategies, and predation risk in white‐tailed deer fawns

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
Horizontal visibility, rather than concealment cover, drove fawn bedsite use and predation risk. Greater field of view decreased the odds of coyote predation, likely by facilitated by early detection. As fawns transitioned from hiders to followers, they shifted from using dense overstory concealment to more open overstory that favored improved escape ...

Hydrophilic Thiol‐Functionalized Silver Nanoparticles as Bio‐Stimulants in Quercus Pubescens Seedling Development

open access: yesChemistrySelect, Volume 11, Issue 33, 1 September 2026.
Surface‐functionalized hydrophilic silver nanoparticles (AgNPs‐3MPS, where 3MPS = sodium 3‐mercapto‐1‐propanesulfonate) were synthesized and characterized. Colloidal AgNPs‐3MPS were tested on Quercus pubescens seedlings to link nanomaterial hydrophilicity and loading with plant responses. Results showed a dose‐dependent effects relevant for sustainable

Image Databases for Pollen Grain Classification: Availability, Quality, and Challenges

open access: yesWIREs Data Mining and Knowledge Discovery, Volume 16, Issue 3, September 2026.
Overview of the study process, from identifying gaps in pollen image databases to a systematic search across six libraries, resulting in 73 final studies, 18 datasets (10 public), and a seven‐point standardization framework proposed under FAIR principles.

Gene up-regulation by DNA demethylation in 35S-gshI-transgenic poplars (Populus x canescens) [PDF]

open access: yes, 2008
Gene expression levels of transgene 35S-gshI (γ-glutamylcysteine synthetase) cloned from E. coli, and the endogenous gene gsh1 of poplar (Populus x canescens) were upregulated by the DNA demethylating agent DHAC (5,6-dihydro-5'-azacytidine ...

Repurposing Bird Bycatch From Camera Traps in Urban Landscapes: A Correlate of Avian and Mammalian Richness?

open access: yesJournal of Zoology, Volume 330, Issue 1, Page 62-70, September 2026.
Here, we evaluated the ecological value of bird detections obtained opportunistically from camera traps by comparing them with standardized point count surveys conducted in 2023–2024, across the metropolitan area of Firenze, central Italy, and explored their potential to indicate broader urban biodiversity patterns through cross‐taxa relationships with
