Habituation in Aedes aegypti mosquito larvae is context specific
ABSTRACTMosquito larvae live in water and perform a stereotyped escape response when a moving object projects its shadow on the water surface, indicating potential risk of predation. Repeated presentations of the shadow induce a decrease in the re...

The early life of king penguins: ontogeny of dive capacity and foraging behaviour in an expert diver
ABSTRACTThe period of emancipation in seabirds, when juveniles change from a terrestrial existence to a life at sea, is associated with many challenges. Apart from finding favourable foraging sites, they have to develop effective prey search patte...

Opposing effects of dopamine on agonistic behaviour in crayfish
ABSTRACTThe effects of dopamine on the agonistic behaviour of crayfish were analysed. When dopamine concentrations of 1 μmol l−1 were injected into large crayfish, individuals were beaten by smaller opponents, despite their physical advantage. Inj...

Vacuolar H + -ATPase and Na + /K + -ATPase energize Na + uptake mechanisms in the nuchal organ of the hyperregulating freshwater crustacean Daphnia magna
ABSTRACTThe nuchal organ of the embryos and neonates of the cladoceran, Daphnia magna, has been shown to be a site of Na+ influx and H+, NH4+ and Cl− efflux. This study combines the scanning ion-selective electrode technique with application of in...

Disentangling the energetic costs of step time asymmetry and step length asymmetry in human walking
ABSTRACTThe metabolic cost of walking in healthy individuals increases with spatiotemporal gait asymmetries. Pathological gait, such as post-stroke, often has asymmetry in step length and step time which may contribute to an increased energy cost....
