Multimodal Deep Learning‐Assisted Microstructural Evaluation System for Sintered NdFeB Magnets

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The performance of sintered NdFeB magnets, especially coercivity, is critically determined by their complex microstructure. However, a quantitative microstructural evaluation system (MES) is much needed but has long been missing in the community.

Transmasculine Pregnancy and the Limits of Reproductive Citizenship: Cisnormativity and Governance in Healthcare Systems in Brazil

open access: yesSexuality, Gender &Policy, Volume 9, Issue 3, August 2026.
ABSTRACT This article examines transmasculine pregnancy as a critical lens through which to analyze the intersections of cisnormativity, reproductive governance, and reproductive citizenship within healthcare systems. While existing research has documented barriers faced by transgender populations, less attention has been paid to how institutional and ...

Farm‐Scale Recharge Pits for Improving Local Groundwater Availability: Insights From a Hardrock Watershed in Rajasthan, India

open access: yesWorld Water Policy, Volume 12, Issue 3, August 2026.
ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and

Conservative roots confer a larger microbial carbon pump efficacy than acquisitive roots by regulating microbial life‐history strategy

open access: yesFunctional Ecology, Volume 40, Issue 8, Page 2617-2627, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root activity creates unique microbial hotspots in the rhizosphere by influencing the metabolic activities of surrounding soil microorganisms, profoundly regulating the dynamics of soil organic carbon (SOC). However, how root economic strategies affect the formation and

Alleviation of phosphorus rather than nitrogen limitation driven by permafrost and landscape effects on Dahurian larch forests

open access: yesFunctional Ecology, Volume 40, Issue 8, Page 2590-2601, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.

Pinus armandii ectomycorrhizas mobilize aluminium‐bound phosphorus via carboxylates along a subtropical altitudinal gradient

open access: yesJournal of Ecology, Volume 114, Issue 8, August 2026.
Ectomycorrhizal roots of Pinus armandii release more carboxylates than non‐mycorrhizal root segments, mobilizing Al‐bound inorganic P. Under the lowest available P conditions, they also secrete more phosphatase, promoting the mineralization of Al‐bound organic P.

Inferring alternative ecosystem states with field survey data

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 8, Page 2256-2276, August 2026.
Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Spatial identification of areas suitable for other effective area‐based conservation measures in the European Union

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Although significant biodiversity has been safeguarded by protected areas (PAs), biodiversity trends continue downward. Within the frameworks of the EU Biodiversity Strategy for 2030 and the new EU Restoration Regulation (2024), conserving critical biodiversity areas is essential.
