...Roy E. Weber; Jane W. Behrens; Hans Malte; Angela Fago SUMMARY With the aim of understanding the molecular underpinnings of the enormous variation in the temperature sensitivity of hemocyanin–O 2 affinity encountered in crustaceans, we measured O 2 binding to Carcinus maenas hemocyanin at two...

...Raymond P. Henry SUMMARY Carbonic anhydrase (CA) activity and relative expression of CA mRNA were measured in the gills of the euryhaline green crab Carcinus maenas in response to eyestalk ablation (ESA), injection of eyestalk extract and exposure to low salinity. For crabs acclimated to 32 p.p.t...

...Ude Cieluch; Klaus Anger; Fabien Aujoulat; Friedrich Buchholz; Mireille Charmantier-Daures; Guy Charmantie SUMMARY The ontogeny of osmoregulation, the development of branchial transporting epithelia and the expression of the enzyme Na + /K + -ATPase were studied in Carcinus maenas (L.) obtained...

.... In the euryhaline green shore crab Carcinus maenas , active excretion of ammonia across isolated gills is reduced by inhibitors of the Na + /K + -ATPase and vacuolar-type H + -ATPase. In addition, a functional dynamic microtubule network is necessary, since application of colchicine, taxol or thiabendazole leads...

...Horst Onken; Sven Riestenpatt SUMMARY Split gill lamellae and gill cuticles of shore crabs ( Carcinus maenas ) adapted to 10 ‰ salinity were mounted in a modified Ussing-type chamber. With NaCl saline on both sides, split gill lamellae generated a short-circuit current ( I sc ) of –301±16 μA cm –2...

... high and variable demands on their reserves of high-energy phosphates. The major invertebrate phosphagen kinase, arginine kinase, is expressed in the gills of two species of euryhaline crabs, the blue crab Callinectes sapidus and the shore crab Carcinus maenas , in which energy-requiring functions...

...Markus K. Phlippen; Simon G. Webster; J. Sook Chung; Heinrich Dircksen ABSTRACT On the basis of detailed analyses of morphological characteristics and behavioural events associated with ecdysis in a crab ( Carcinus maenas ) and a crayfish ( Orconectes limosus ), a comprehensive substaging system...

...Lynne U. Sneddon; Alan C. Taylor; Felicity A. Huntingford; David G. Watson ABSTRACT To investigate the role of certain neurohormones in agonistic behaviour, fights were staged between pairs of size-matched male shore crabs Carcinus maenas , and blood samples were taken immediately after...

...Robert K. Josephson; Darrell R. Stokes ABSTRACT Active shortening of respiratory muscle L2B from the crab Carcinus maenas results in contractile deactivation, seen as (1) a decline of force during the course of isovelocity shortening, (2) a reduction in the rate of force redevelopment following...

...Fabrice Durand; Fabienne Chausson; Michèle Regnault ABSTRACT Carcinus maenas and Necora puber were exposed to air for 72 h and 18 h, respectively, at 18 °C. Changes in the free amino acid (FAA) content of their muscle, hepatopancreas and haemolymph were recorded during air-exposure and subsequent...

...Robert K. Josephson; Darrell R. Stokes ABSTRACT Muscle force during active lengthening was characterized for scaphognathite levator muscle L2B from the crab Carcinus maenas . The muscle was tetanically stimulated and, during the peak of the contraction, stretched at constant velocity. The total...

..., behavioural hypothermia was demonstrated in the shore crab Carcinus maenas . The animals moved to a cooler environment when exposed to hypoxic conditions. A decrease in preferred temperature of the same magnitude was also found when normoxic animals were injected with an iso-osmotic lactate solution resulting...

...R. A. Dicaprio; G. Jordan; T. Hampton ABSTRACT The central pattern generator responsible for the gill ventilation rhythm in the shore crab Carcinus maenas can produce a functional motor pattern over a large (eightfold) range of cycle frequencies. One way to continue to generate a functional motor...
