- Non-centralized and functionally localized nervous system of ophiuroids: evidence from topical anesthetic experiments
Summary: Functional localization exists in the nervous system of ophiuroids although there is no evidence of a morphological counterpart to the central nervous system of other species.
- Strategies used by two apterous strains of the pea aphid Acyrthosiphon pisum for passive dispersal
Summary: Two strains of pea aphid (Acyrthosiphon pisum) show different dispersal strategies, glycogen level and probing behaviors. One strain [Yangling strain (YL)] moves longer and disperses wider than another strain [Lanzhou (LZ)] based on higher glycogen. LZ strain probed more frequently, and identified plant more accurately than YL strain.
- The invisible fish: hydrodynamic constraints for predator-prey interaction in fossil fish Saurichthys compared to recent actinopterygians
Summary: For the first time, the hydrodynamic properties of a fossil fish, Saurichthys, have been investigated using computational fluid dynamics. Low drag coefficient and small area of flow disturbance prove fast-start predatory adaptation.
- Inter- vs intra-individual variation and temporal repeatability of escape responses in the coral reef fish Amblyglyphidodon curacao
Summary: Quantification of the inter- and intra-individual variation in behavioural and kinematic components of escape performance of the tropical damselfish Amblyglyphidodon curacao found no evidence of habituation or fatigue due to repeated stimulations.
