Summary: This Review compares echolocation in bats and toothed whales, with special emphasis on predator–prey interactions and adaptive sonar behaviors used to negotiate complex natural scenes.
Summary: The flight apparatus (wings, flight muscles, neuro-muscular control) of vertebrates is fine-tuned for efficient flight. I review causes and consequences of wear, damage and moult gaps that temporarily affect wing morphology and flight performance.
Close encounters of three kinds: impacts of leg, wing and body collisions on flight performance in carpenter bees
Summary: Flying insects frequently collide with obstacles when navigating dense clutter, but the performance consequences of collisions depend on which parts of the insect (e.g. leg, wing, body) are involved.
Summary: Quantitative analysis of flight behavior, modeling and numerical simulation shows that the abdomen of hawkmoths can regulate wing-generated flight torques about the vertical (yaw) axis.
Developmental environment has lasting effects on amphibian post-metamorphic behavior and thermal physiology
Highlighted Article: Climatic stressors during development have lasting impacts on the thermal physiology, performance and behavior of juvenile frogs post-metamorphosis, with implications for susceptibility to predators and pathogens in subsequent life stages.
Summary: Swimming lampreys largely compensate for changes in viscosity, maintaining similar kinematics over 20× changes in viscosity, suggesting that they use sensory feedback to regulate their body waveform.
Low production of mitochondrial reactive oxygen species after anoxia and reoxygenation in turtle hearts
Highlighted Article: Low rates of mitochondrial O2·− production are responsible for lack of tissue damage upon reoxygenation after anoxia in turtles, likely owing to low succinate accumulation and low degradation of adenine nucleotides.
Editor's choice: To achieve rapid movements through seawater, fan worms have developed functional morphological adaptations to reduce fluidic drag, including the flattening of their pinnules and the deformation of bodily segmental ridges.
Sensorimotor control of swimming Polypterus senegalus is preserved during sensory deprivation conditions across altered environments
Summary: Lateral line and visual systems of Polypterus senegalus are not critical for responding to fluid viscosity but may be involved in a forward model of motor control to adjust locomotion.
Experimental reduction in blood oxygen-carrying capacity alters foraging behaviour in a colonial waterbird
Summary: Experimental reduction of blood oxygen-carrying capacity in incubating black-headed gulls results in fine-scale alterations in foraging behaviour, as birds with induced haemolytic anaemia perform fewer, but longer foraging trips.
