- Light level impacts locomotor biomechanics in a secondarily diurnal gecko, Rhoptropus afer
Highlighted Article: Vision is critical for locomotion, but it is poorly understood in relation to locomotor biomechanics in non-human vertebrates. The secondarily diurnal gecko, Rhoptropus afer, shows changes in speed and posture in low light conditions.
- Consequences of lost endings: caudal autotomy as a lens for focusing attention on tail function during locomotion
Summary: We develop a framework for thinking about how tail loss can affect fitness through its effects on locomotion, and review results from past studies to inform and support this framework.
- Skating by: low energetic costs of swimming in a batoid fish
Summary: The little skate exhibits decreasing mass-adjusted swimming metabolic rates with increasing speed, which are the lowest values among elasmobranchs. However, its cost of transport is one of the highest measured for fishes.
- Building a dishonest signal: the functional basis of unreliable signals of strength in males of the two-toned fiddler crab, Uca vomeris
Summary: The frequencies of reliable and unreliable signals of strength in Uca vomeris are influenced by the structural and physiological mechanisms behind force production in the major claw.
- Sexual differences in exploration behavior in Xenopus tropicalis?
Summary: Differences in exploration behavior exist between male and female frogs, with males exploring novel environments more than females; this behavior is decoupled from performance in both sexes.
