- Honeybees use the skyline in orientation
Summary: Honeybees can orient using the skyline, the panoramic silhouette of terrestrial objects against the sky, an ability probably important to bees in their everyday navigation.
- The Ol1mpiad: concordance of behavioural faculties of stage 1 and stage 3 Drosophila larvae
Summary: A community-based survey of the behavioural faculties of stage 1 Drosophila larvae, providing a resource for relating these behavioural faculties to the upcoming connectome of their nervous system.
- Propulsion in hexapod locomotion: how do desert ants traverse slopes?
Summary: Analysis of the alternating tripod gait of desert ants together with ground reaction forces and weight-specific leg impulses during inclined locomotion reveals the mechanical function of the hind legs as the main brake on downslopes (–60 and –30 deg) and the front legs as the main motor on steep upslopes (+60 deg).
- Male bumblebees perform learning flights on leaving a flower but not when leaving their nest
Summary: Bumblebee males leave their nest directly, but they perform learning flights when they leave artificial flowers, during which they turn back and fixate the flowers.
- Importance of the antenniform legs, but not vision, for homing by the neotropical whip spider Paraphrynus laevifrons
Summary: Tropical amblypygids inhabit structurally complex habitats, yet navigate home in the dark after a night hunting prey; olfaction appears to be important for navigation.
- Ontogeny of learning walks and the acquisition of landmark information in desert ants, Cataglyphis fortis
Summary: When leaving their nest for the first time, Cataglyphis fortis ants perform a sequence of learning walks during which they learn the surrounding landmark panorama with increasing accuracy.
- Pigeon navigation: exposure to environmental odours prior to release is sufficient for homeward orientation, but not for homing
Summary: Environmental local odours perceived at the release site are sufficient for pigeons’ homeward orientation, but pigeons can successfully home only if they can rely on olfactory cues during flight beyond the release site.
- Evidence of trapline foraging in honeybees
Summary: Honeybees can learn stable foraging routes, minimising the overall travel distances between multiple flower patches.
- How to find home backwards? Navigation during rearward homing of Cataglyphis fortis desert ants
Highlighted Article: Backward-homing Cataglyphis fortis ants exhibit angular and distance gauging comparable to that of forward-homing ants.
- Echo-acoustic flow affects flight in bats
Summary: Sensory flow is a ubiquitous principle for flight guidance, independent of the fundamentally different peripheral representation of flow across the senses of vision and echolocation.
