Capsicum chinense as an African traditional vegetable: Culture, resilience, and opportunity

PLANTS, PEOPLE, PLANET, EarlyView.
Capsicum chinense is central to everyday diets, cultural identity, and smallholder livelihoods across Sub‐Saharan Africa, yet remains overlooked in agricultural research and policy. This paper reframes C. chinense as a traditional, climate‐resilient vegetable shaped by centuries of farmer stewardship and cultural selection.

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.

Autonomous Navigation in Large‐Scale Underground Environments Based on a Purely Topological Understanding of Tunnel Networks

Journal of Field Robotics, EarlyView.
ABSTRACT This work presents a non‐geometrical navigation approach based on a purely topological understanding of underground environments. By conceptualizing subterranean scenarios as a set of tunnels that intersect with each other, and taking a navigation approach based on topological instructions, we simplify the navigation problem to the sequential ...

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

Journal of Field Robotics, EarlyView.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...
