Observations of total RONO2 over the boreal forest: NO x sinks and HNO3 sources [PDF]

, 2013
In contrast with the textbook view of remote chemistry where HNO 3 formation is the primary sink of nitrogen oxides, recent theoretical analyses show that formation of RONO2 (ΣANs) from isoprene and other terpene precursors is the primary net chemical ...

Ips acuminatus (Gyllenhal) in the Czech Republic: Flight dynamics and adult population structure

Physiological Entomology, Volume 51, Issue 1, Page 136-146, March 2026.
Ips acuminatus exhibits a univoltine life cycle in Central Europe and no full second generation in midsummer. The sex ratio shifts from male‐biased in spring to slightly female‐biased with the season, with over 90% of females mated. Among the pheromone lures tested, the ACP was most attractive, and combining ACP and PH lures could be used for effective

Temperature Sensitivity of Leaf Wax n‐Alkane Carbon Isotopes: Mechanisms and Implications for Terrestrial Paleoclimates

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract While climate signals encapsulated in the 13C content of C3 plants' leaf wax n‐alkanes are largely tied to precipitation, they may also be sensitive to plant physiological responses to temperature. In this study, statistical analyses on a global data set of modern plants reveal a correlation between the 13C discrimination for leaf waxes ...

Combined Effects of Air Humidity and Temperature on Biogenic Volatile Organic Compound Emissions and Photosynthesis

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract Temperature and air humidity are critical environmental factors regulating photosynthesis and biogenic volatile organic compound (BVOC) emissions from plants, which influence air quality and climate change. While previous research has demonstrated the impacts of temperature on photosynthesis and BVOCs, the effects of humidity and the combined ...

Foeniculum vulgare Essential Oils: Chemical Composition, Antioxidant and Antimicrobial Activities [PDF]

, 2010
The essential oils from Foeniculum vulgare commercial aerial parts and fruits were isolated by hydrodistillation, with different distillation times (30 min, I h, 2 h and 3 h), and analyzed by GC and GC-MS. The antioxidant ability was estimated using four

Multi‐Omics Reveal the Dysregulated Gut‐Joint Axis in Knee Synovitis: Data from Two Osteoarthritis Studies in China

Advanced Science, Volume 13, Issue 7, 3 February 2026.
The “gut‐joint axis” in knee synovitis is uncovered. Integrated multi‐omics studies are conducted in two independent osteoarthritis cohorts. Synovitis is characterized an increased F/B ratio, as well as alterations of 3‐HIA, geranic acid, and TWEAK. Upregulated TWEAK receptor is found in high‐grade synovitis, and inversely correlated with lower TWEAK ...

Volatile organic compounds emitted from fungal-rotting beech (Fagus sylvatica) [PDF]

, 2008
Chemo-communication is an important mode of interaction within ecosystem. The living organism in the ecosystem can deliver signals to conspecifics, to co-organisms, and unintentionally to their enemies, by emitting the volatile organic compounds (VOCs ...

Uncovering the Key Factors Influencing Phytochemical and Phytopharmacological Properties During Medicinal Plant Processing

eFood, Volume 7, Issue 1, February 2026.
From farm to pharma, this review details the engineering of quality in medicinal plants through a science‐driven approach: it first elucidates how genetic and environmental factors inscribe the plant's phytochemical and phytopharmacological profile before harvest, and then dissects the postharvest techniques and technologies—chemical and thermal pre ...
