Evaluation of methods for the analysis of oxygen and carbon dioxide in water, sediment, litter, and soil

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 10, October 2026.
Abstract Choosing an appropriate analyzer to measure concentrations of oxygen (O2) and carbon dioxide (CO2) during biogeochemical cycling studies can be difficult, considering the range of options available. While several studies examine the abilities of specific analyzers, comparison of multiple analyzers and environmental sample types is lacking.

Feasibility of Spin‐ and Gradient‐Echo Dynamic Susceptibility Contrast MRI for Microvascular Characterization at 7 Tesla

open access: yesNMR in Biomedicine, Volume 39, Issue 10, October 2026.
Spin‐ and‐gradient‐echo DSC MRI at 7 T allows for characterization of the microvasculature at an improved resolution and a reduced gadolinium‐based contrast agent dosage while maintaining increased vascular contrast. Ratios between normal‐appearing gray matter and white matter for relative cerebral blood volume and vessel size estimates were similar ...

Forecasting the impact of food‐provisioning and other stressors on a marine top‐predator population

open access: yesOikos, Volume 2026, Issue 10, October 2026.
Wildlife tourism can alter animal behavior, affect vital rates and diminish population viability but its impact in the context of other human‐ and environmental disturbances, remain largely unstudied. Using simulation models and leveraging a robust long‐term dataset spanning eight years, we evaluated the contribution of wildlife feeding, in the context

Modeling of the Accumulated Nitrogen Loss by Volatilization in Topdressing Fertilization in Corn Plants

open access: yesPlant-Environment Interactions, Volume 7, Issue 5, October 2026.
ABSTRACT Corn cultivation is one of the most important in the world. Urea possesses a high concentration of nitrogen, which is very important to corn crops, is easily handled, and has a lower cost per kilogram of nitrogen, but it presents high losses of this nutrient through volatilization. Therefore, technologies are developed to minimize these losses,
