Relative Validity of Food Frequency Questionnaires in Adult Populations: A Systematic Review and Meta‐Analysis

open access: yesFood Science &Nutrition, Volume 14, Issue 10, October 2026.
This meta‐analysis demonstrates that digital Food Frequency Questionnaires are reliable tools for ranking habitual dietary intake in adults. Validation against 24‐h recalls and food records shows moderate‐to‐good correlation coefficients, particularly for carbohydrates and fiber. Factors such as interviewer administration and higher item counts enhance

Nitrogen Fertilization Temporarily Enhances Phosphatase Activity in a High‐P Loamy Sand

open access: yesJournal of Plant Nutrition and Soil Science, Volume 189, Issue 5, Page 794-802, October 2026.
ABSTRACT Background Efficient plant utilization of soil phosphorus (P) is essential to reduce dependence on mineral P fertilizers in intensive agriculture. Input of mineral nitrogen (N) fertilizers and its chemical form may influence the activity of P mineralizing enzymes, but how this interaction operates under field conditions in a soil with high P ...

Phenological Flexibility in Nesting Grassland Birds Over a Half Century Informs Timing of Management

open access: yesGlobal Change Biology, Volume 32, Issue 10, October 2026.
Using > 170,000 nest records from 44 North American grassland bird species, we quantified how temperature, precipitation, and vegetation phenology shape early, peak, and late nesting across broad spatial gradients. Spatial predictions identify geographic variation in breeding phenology that can inform the timing of management actions under changing ...

Seasonal and Diel Acoustic Occurrence of Sei Whales in Oregon, USA

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The behavior, distribution, and life history of sei whales (Balaenoptera borealis) are largely unknown in the North Pacific. We analyzed data from three bottom‐mounted acoustic recorders deployed 25 (shelf; depth = 300 m), 45 (slope; depth = 630 m), and 65 (abyssal; depth = 2860 m) nautical miles off of Newport, Oregon, USA that recorded ...

Thermotolerance thresholds of the photosystem II increase with elevation in conifer species in the Spanish Pyrenees

open access: yesPlant Biology, Volume 28, Issue 6, Page 2142-2146, October 2026.
In vitro‐tested photosystem II thermotolerance of seven temperate conifers indicated higher thermal thresholds in species growing in high elevations compared to those in the lowlands. Higher thermotolerance might be explained by the adaptation of species in higher elevations to extreme diurnal temperature fluctuations.
