Exploring eco‐evolutionary and temporal patterns of arbuscular mycorrhizal fungal communities colonizing Sorghum bicolor across sites of contrasting land use history and climate

PLANTS, PEOPLE, PLANET, EarlyView.
Sorghum bicolor is a globally important cereal crop with annual yields exceeding 50 million tons across more than 100 countries and can be grown on marginal lands where conventional agriculture is limited. We examined how eight genetically diverse sorghum genotypes shaped arbuscular mycorrhizal fungal (AMF) community assembly across two contrasting ...

Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

PLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

Directive Antenna Clutter Loss in Slant Paths

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper investigates the development of a clutter loss model specifically for slant paths involving directive antennas. Conventionally, clutter loss is characterized by using isotropic antennas to facilitate standard link budget calculations via single antenna gain values.
