orientation
- Animal navigation: a noisy magnetic sense?
Summary: Magnetic orientation responses in animals are often weak and difficult to elicit experimentally. A possible explanation is that the magnetic compass is ‘noisy’ and cannot acquire precise magnetic information over short time periods.
- Path integration error and adaptable search behaviors in a mantis shrimp
Summary: Mantis shrimp use path integration, an error-prone navigational strategy, when traveling home. When path integration fails, mantis shrimp employ a stereotyped yet flexible search pattern to locate their homes.
- Connecting brain to behaviour: a role for general purpose steering circuits in insect orientation?
Summary: We describe how a highly conserved insect brain region may play a general role in a wide variety of insect orientation behaviours.
- Panorama similarity and navigational knowledge in the nocturnal bull ant Myrmecia midas
Summary: Myrmecia midas show navigational performance differences based on foraging experience. Differences in navigational success correspond with the degree of similarity between the panorama at release locations and panoramas at known locations.
- There and back again: natal homing by magnetic navigation in sea turtles and salmon
Summary: New findings indicate that long-distance natal homing in salmon and sea turtles involves an ability to navigate back to the magnetic signature of the home area.
- Behavioural and neuronal basis of olfactory imprinting and kin recognition in larval fish
Summary: This Review focuses on olfactory imprinting processes that numerous species use to recognize kin or their natal environment later in life.
- Evidence for a southward autumn migration of nocturnal noctuid moths in central Europe
Summary: During autumn in central Europe, red underwing and large yellow underwing moths make a southward oriented nocturnal migration, although on foggy evenings, the latter species becomes disoriented.
- Evidence for spatial vision in Chiton tuberculatus, a chiton with eyespots
Summary: Certain chitons have hundreds to thousands of eyespots (∼35 µm) distributed across their shell plates; these eyespots are associated with spatial vision.
- Time-optimized path choice in the termite-hunting ant Megaponera analis
Summary: Individual scouts of a termite-hunting ant species are capable of walking the fastest path to a food source rather than the shortest.
