J Exp Biol (2022) 225 (12): jeb244145.
Published: 16 June 2022
...Aakriti Gupta; Sarah A. Breedon; Kenneth B. Storey ABSTRACT Tumor suppressing transcription factor p53 regulates multiple pathways including DNA repair, cell survival, apoptosis and autophagy. Here, we studied the stress-induced activation of p53 in anoxic crayfish ( Faxonius virilis ). Relative...

...Julien Bacqué-Cazenave; Marion Berthomieu; Daniel Cattaert; Pascal Fossat; Jean Paul Delbecque ABSTRACT The molting process of arthropods, chiefly controlled by ecdysteroids, is generally considered very stressful. Our previous investigations have shown that crayfish, after having experienced...

... the Australian red claw crayfish Cherax quadricarinatus (termed Cq-IAG ). While a few insulin-like AG genes have been identified in crustaceans, other AG-specific genes have not been documented until now. In the present study, we describe the recent identification of a non-IAG AG-specific transcript obtained...

...Makoto Araki; Takuya Hasegawa; Shohei Komatsuda; Toshiki Nagayama SUMMARY Strong stimuli applied to the tailfan of the crayfish Procambarus clarkii evoked lateral giant interneurone (LG)-mediated tailflips. When the sensory stimulus was applied repeatedly, the response of the LG habituated until...

...Ryusuke Ueno; Toshiki Nagayama SUMMARY We characterized the role of chelae during agonistic encounters of the crayfish Procambarus clarkii . Physical asymmetries in body length, body mass and chelae size were directly related to dominance hierarchy formation. More than 80% of winning crayfish had...

... with upper and lower voluntary escape temperatures of 25.9 and 21.8°C, respectively. If this preferred temperature zone (21.8–25.9°C) was valued as a resource, given the choice between a preferred temperature and a non-preferred temperature, crayfish should compete over the preferred temperature...

...Daisuke Sato; Toshiki Nagayama SUMMARY We have characterized the behavioural patterns of crayfish during agonistic bouts between groups of crayfish of four different body lengths (9–19, 20–32, 41–48 and 69–75 mm) to characterize changes in the patterns of agonistic encounter during development...

...Sawako Fujimoto; Bunpei Hirata; Toshiki Nagayama SUMMARY Crayfish showed avoidance reactions when mechanical stimulation was applied to their tailfan. The response pattern of the avoidance reaction was dependent on crayfish size. Small crayfish showed an escape-like dart response while larger...

... and function of the proteins and genes contributing to the cycling of the clock in crayfish Procambarus clarkii are scarce. In this study, we investigated whether three proteins that interact in the feedback loop of the molecular clock described for Drosophila are expressed in the putative circadian pacemakers...

... of aerial respiratory behavior. Juvenile Lymnaea , however, can form LTM following classical conditioning of appetitive behaviors. Here, we demonstrate that laboratory-reared juvenile Lymnaea have the ability to detect the presence of a sympatric predator (i.e. crayfish) and respond to the predator...

...N. Tschuluun; W. M. Hall; B. Mulloney SUMMARY The crayfish swimmeret system undergoes transitions between a silent state and an active state. In the silent state, no patterned firing occurs in swimmeret motor neurons. In the active state, bursts of spikes in power stroke motor neurons alternate...

Published: 1 May 2008
...William H. Liden; Jens Herberholz SUMMARY One of the most important decisions any animal has to make is how to respond to sensory cues that suggest an imminent attack by a predator. We measured behavioral and neural responses of juvenile crayfish to moving shadows of different velocities while...

...P. Denissenko; S. Lukaschuk; T. Breithaupt SUMMARY Crayfish are nocturnal animals that mainly rely on their chemoreceptors to locate food. On a crayfish scale, chemical stimuli received from a distant source are dispersed by an ambient flow rather than molecular diffusion. When the flow is weak...
