Grasshoppers alter jumping biomechanics to enhance escape performance under chronic risk of spider predation
1. Prey can increase the probability of escaping a predator attack by adopting either behavioural tactics that provide more time or less distance to escape or by increasing their escape performances. It is assumed that the ability to improve escape performances is reserved for species that respond to chronic predation risk by substantially altering morphological traits related to locomotion. Th...

متن کاملAirborne Acoustic Perception by a Jumping Spider
Jumping spiders (Salticidae) are famous for their visually driven behaviors [1]. Here, however, we present behavioral and neurophysiological evidence that these animals also perceive and respond to airborne acoustic stimuli, even when the distance between the animal and the sound source is relatively large (∼3 m) and with stimulus amplitudes at the position of the spider of ∼65 dB sound pressur...
متن کاملCues by which Portia fimbriata, an araneophagic jumping spider, distinguishes jumping-spider prey from other prey.
Portia fimbriata from Queensland, Australia, is an araneophagic jumping spider (Salticidae) that includes in its predatory strategy a tactic (cryptic stalking) enabling it to prey effectively on a wide range of salticids from other genera. Optical cues used by P. fimbriata to identify the salticid species on which it most commonly preys, Jacksonoides queenslandicus, were investigated experiment...
متن کاملNature of Predation Risk Cues in Container Systems: Mosquito Responses to Solid Residues From Predation.
In aquatic systems, prey animals associate predation risk with cues that originate either from the predator or from injured conspecifics. Sources and benefits of these cues have received considerable attention in river, lake, and pond ecosystems but are less well understood in small container ecosystems that can hold less than a liter of water. Mosquitoes Aedes triseriatus (Say) and Aedes albop...
