Enhancing Neglected and Underutilized Crop Species (NUCS) in Nepal: Unlocking Their Potential for Climate Resilience, Food Security, and Agrobiodiversity

Advances in Agriculture, Volume 2026, Issue 1, 2026.
Background The global dominance of a few major cereal crops has led to the marginalization of traditional species, reducing agrobiodiversity and increasing the vulnerability of food systems. Changing climate conditions, particularly intensifying drought stress, further threaten global food security.

Metabarcoding Reveals Fine Scale Patterns of Trophic Resource Use and Partitioning Along Gradients of Land Use and Deer Density in a Multi‐Species Ungulate Community

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We used DNA metabarcoding of 2,568 fecal samples to examine seasonal diets and resource partitioning among four deer species (moose, roe deer, red deer, fallow deer) across two Swedish landscapes. Deer consumed a wide range of plants, but diets were typically dominated by a few key taxa, with distinct dietary separation between moose and smaller deer ...

Reclaiming Disturbed Sites: Influence of Planting Time, First‐Year Mowing, and Seed Mix Richness Over 8 Years

Applied Vegetation Science, Volume 28, Issue 4, October/December 2025.
Eight years after revegetation, seed mix richness, spring or fall planting time, and first‐year mowing had limited effects on vegetation recovery. Using more species in the seed mix does not guarantee a higher species richness in plant communities, and non‐native species control is essential for long‐term revegetation success.

Greater sage‐grouse habitat restoration with range management, revegetation, and herbicide

Restoration Ecology, Volume 33, Issue 7, September 2025.
Populations of Greater sage‐grouse (Centrocercus urophasianus), an iconic symbol of sagebrush ecosystems, are declining in native grasslands due to habitat loss, degradation, and fragmentation. We conducted a field experiment in Grasslands National Park, Saskatchewan, Canada, to investigate how disturbance and land management (cattle grazed, bison ...

Plant‐Based Biosynthesis of Metal and Metal Oxide Nanoparticles: An Update on Antimicrobial and Anticancer Activity

ChemBioEng Reviews, Volume 11, Issue 6, December 2024.
When it comes to finding novel ways to battle newly developing pathogenic strains and illnesses, nanoparticles are the first line of defense. Plant‐based nanoparticles are showing more significance over chemically or physically synthesized nanoparticles. Several plant species and their constituent parts have found several applications in medicine. They
