Cardiovascular Responses Resulting from Variation in External Salinity in the Dungeness Crab, Cancer magister
Haemolymph flow was assessed simultaneously in the five arterial systems leaving the heart of the crab Cancer magister, allowing calculation of stroke volume and cardiac output via heart rate.Expand

Application and In situ calibration of a pulsed-doppler flowmeter for blood flow measurement in crustaceans
The pulsed-Doppler flowmeter permits continuous, non-invasive measurement of blood flow through several arteries simultaneously. Summation of volume flow rates through all arteries leaving the heartExpand

Salinity preference of the shore crab Carcinus maenas in relation to coloration during intermoult and to prior acclimation
Abstract Intermoult Carcinus maenas (Crustacea: Decapoda) exhibit a range of carapace colours from green through orange to red, reflecting increasing lengths of intermoult duration, with red crabsExpand

Distribution and rhythmic locomotor patterns of estuarine and open-shore populations of Carcinus maenas
Populations of Carcinus maenas (Crustacea: Decapoda) from an estuary and from the open shore were compared for salinity tolerance and rhythmic locomotor activity. Estuarine crabs were shown to beExpand

  • The Biological Bulletin
  • 1 February 2003
The thermoregulatory behavior of Hemigrapsus nudus, the amphibious purple shore crab, was examined in both aquatic and aerial environments. Crabs warmed and cooled more rapidly in water than in air.Expand

Intraspecific morphological variation related to the moult-cycle in colour forms of the shore crab Carcinus maenas
The common shore crab Carcinus maenas exhibits a range of carapace colours from green through orange to red, green forms showing some differences of distribution from red/orange forms. To test theExpand

Burying behaviour of two sympatric crab species: Cancer magister and Cancer productus
The mechanics and emergence patterns associated with burying behaviour were investigated in the Dungeness crab, Cancer magister , and the red rock crab, Cancer productus . Cancer magister used bothExpand

Circulatory modification in the blue crab Callinectes sapidus, during exposure and acclimation to low salinity
Abstract A pulsed-Doppler flowmeter was used to measure heart rate and haemolymph flow rates in each arterial system of the blue crab, Callinectes sapidus, enabling calculation of stroke volume andExpand
