Of hummingbirds and helicopters: Hovering costs, competitive ability, and foraging strategies [PDF]
, 2004 Wing morphology and flight kinematics profoundly influence foraging costs and the overall behavioral ecology of hummingbirds. By analogy with helicopters, previous energetic studies have applied the momentum theory of aircraft propellers to estimate ...

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots
Advanced Robotics Research, EarlyView.Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...

Predator Cues Reduce American Beaver Use of Foraging Trails
Human-Wildlife Interactions, 2017 Herbivores must balance energy needs with avoiding risks, using various cues to assess predation risk. The American beaver (Castor canadensis) is a semi-aquatic herbivore vulnerable to predation on land by wolves (Canis lupis).

Olfactory cue use by three-spined sticklebacks foraging in turbid water: prey detection or prey location? [PDF]
, 2012 Foraging, when senses are limited to olfaction, is composed of two distinct stages: the detection of prey and the location of prey. While specialist olfactory foragers are able to locate prey using olfactory cues alone, this may not be the case for ...

Advanced Robotics Research, EarlyView.Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Ecology and EvolutionThe overwhelming majority of research on wild bumble bees has focused on the social colony stage. Nest‐founding queens in the early season are difficult to study because incipient nests are challenging to find in the wild and the foundress queen flight ...

Ecology and Evolution, 2021 For procellariiform seabirds, wind and morphology are crucial determinants of flight costs and flight speeds. During chick‐rearing, parental seabirds commute frequently to provision their chicks, and their body mass typically changes between outbound and
