Influence of Foraging Effort and Diet on Maternal Energy Stores and Offspring Weaning Mass in Gray Seals (<i>Halichoerus grypus</i>). [PDF]

Ecol Evol
Understanding how foraging behavior and diet influences individual reproductive success is a key interest in evolutionary ecology. Using data collected from female gray seals (Halichoerus grypus) at Sable Island, Canada, between 1995 and 2018, we tested the hypothesis that differences in foraging behavior and diet prior to the breeding season ...

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,
