Nitrogen acquisition and retention pathways in sustainable perennial bioenergy grass cropping systems

GCB Bioenergy, Volume 16, Issue 6, June 2024.
Perennial tall grasses sustain high biomass yield with minimal synthetic nitrogen (N) fertilizer, potentially by leveraging biological N fixation and nitrification inhibition. Enhancing these traits through research and breeding can further reduce their reliance on N fertilizer and thereby support more resilient and environmentally sustainable ...

Local perceptions of the benefits versus negative impacts of weedy grasses in central Madagascar, with a focus on the genus Digitaria

PLANTS, PEOPLE, PLANET, Volume 6, Issue 3, Page 710-728, May 2024.
Plants and agricultural practices are an integral part of human food systems and well‐being. Here, an example of an ethnobotanical research approach is provided to increase our understanding of the relationship between plants and human activities in Madagascar, where the agricultural sector is the local economy basis.

Fertilization during mineland rehabilitation may shift competitive outcomes toward invasive species

Restoration Ecology, Volume 32, Issue 4, May 2024.
Managing invasive species is essential for achieving mineland rehabilitation goals and ensuring the long‐term provision of critical ecosystem services while preventing new dispersion sources to neighboring areas. Traditional techniques include chemical and manual weeding, but frequent reinvasion limits their long‐term success.

Systematic reduction in seed rain of large‐seeded and endozoochorous species in pastures compared to forests along a tropical elevational gradient

Applied Vegetation Science, Volume 27, Issue 2, April/June 2024.
By analyzing variation in seed rain among old‐growth montane forests and livestock pastures along a 2,000 m elevational gradient in the tropical Andes of southern Ecuador, this study reveals that large seeds and endozoochorous species are less prevalent in seed rain from pastures compared to seed rain from forests at the same elevation.
