Rangeland Productivity and Exploitation in the Sahel

open access: yesScience, 1983
Results of a Malian-Dutch research project on the Sahelian pastures and their utilization suggest reasons why some efforts to develop traditional livestock farming in this area have been unsuccessful. Failure to appreciate the effects of low soil fertility as well as low rainfall on pasture production has resulted in underestimation of the productivity

Rice EMF3 Alleles Adjust Flower Opening Time to Enhance the Seed Setting Rate Under High Temperature Stress

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT To safeguard global food security against rapid population growth and a warming world, the effective genetic improvement of cereals is imperative. Flower opening time (FOT) critically affects the seed setting rate. In this study, we identified a gene, EARLY‐MORNING FLOWERING 3 (EMF3), in which single‐nucleotide substitutions strongly modulate ...

Developmental Profiling of Structural and Functional Maturation in Mouse Corpus Callosum

open access: yesGlia, Volume 74, Issue 6, June 2026.
Progressive myelin development in mouse corpus callosum is accompanied by gradual decrease in oligodendrocyte precursor cell density and increase in oligodendrocyte density. Pro‐Capase‐3 is transiently upregulated in oligodendrocyte during postnatal development.

Roadblock Geographies: A Typology of Extraction, Circulation, and Authority in Conflict

open access: yesArea, Volume 58, Issue 2, June 2026.
Short Abstract This article develops a typology of roadblock geographies in conflict‐affected borderlands as extractive landscapes. Drawing on transport geography, it identifies how infrastructural variation—footpaths, roads and ports—shapes who extracts rents, how and to what effect.

Understanding the Zonal Variability in Projections of Sahel Precipitation

open access: yesGeophysical Research Letters
The uncertainty in precipitation projections across the Sahel has persisted across generations of climate models. Many projections show a zonal dipole in the sign of precipitation change, with wetting across the Central Sahel and drying across the ...
