Toward More Autonomous Soft Robots: Development and Characterization of a 3D‐Printed Pneumatic Contact Sensor for a Six‐Legged Soft Robotic Walker

open access: yesAdvanced Intelligent Systems, EarlyView.
This article introduces a fully 3D‐printed, electronics‐free sensory system for a six‐legged soft robot, enabling adaptive responses such as obstacle detection and directional changes using pneumatic logic gates. The design demonstrates efficient, robust operation through rapid sensor feedback and autonomous functionality, highlighting new ...

Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

Reconstructing the evolutionary history of herbaceous crops through trait‐based ecology

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Reconstructing the evolution of crop plants is fundamental to understanding their origins, ecological adaptations, and impacts on ecosystem processes. However, our understanding of crop evolution stems largely from archaeology and genetics, with less focus on a trait‐based ecological approach.
