Contrasting Trends in Plant Diversity and Soil Carbon Mineralization Under Precipitation‐Driven Vegetation and Soil Carbon Dynamics in the Mongolian Plateau

open access: yesEcology and Evolution
Climatic shifts critically regulate soil organic carbon (SOC) dynamics, biodiversity, and productivity in grasslands. However, the mechanisms linking abiotic/biotic factors to plant diversity–SOC mineralization synergies remain unclear.

A Cross-Scale Approach for Estimating AGB of Caragana jubata Shrubs in Subalpine Meadows

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Shrub encroachment significantly affects carbon cycling in grassland ecosystems. In recent years, the expansion of Caragana jubata in subalpine meadows has become a pressing ecological issue. Rapid and accurate estimation of its aboveground biomass (AGB)

Developing and deploying an unmanned aerial system–based phenotyping program for maturity to support soybean breeding

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Soybean [Glycine max (L.) Merr.] varieties are categorized into different relative maturity groups (MGs) that correspond to the approximate region that the variety is best adapted. Maturity is an important trait that growers consider when deciding which varieties to plant and for breeders as a covariate to compare genotypes.

Paleohydraulics and hydrodynamics of Scabland floods [PDF]

open access: yes
The last major episode of scabland flooding (approx. 18,000-13,000 years B.P.) left considerable high-water mark evidence in the form of: (1) eroded channel margins; (2) depositional features; (3) ice-rafter erratics; and (4) divide crossings. These were

Microorganisms Control Litter Decomposition and Drive Grassland Soil C Stabilization by Regulating Exoenzymes

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
Grazing exclusion increased the percentage of litter‐derived C incorporation into both labile and stable SOC pools because of the higher litter quantity and microbial activities than that in the grazed grasslands. ABSTRACT Litter decomposition and microbial activity are important factors affecting soil organic carbon (SOC) sequestration in the ...

Loess Studies in Aotearoa New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

An insight into the different responses to salt stress in growth characteristics of two legume species during seedling growth

open access: yesFrontiers in Plant Science
Legumes play a crucial role in the restoration and utilization of salinized grassland. To explore the physiological response mechanism of Astragalus membranaceus and Medicago sativa seedlings to salt stress, salt stress culture experiments with five NaCl
