Carapace Colour, Inter-moult Duration and the Behavioural and Physiological Ecology of the Shore CrabCarcinus maenas
Abstract Adult male Carcinus maenas occur on the shore with carapace colours ranging from green to deep red. In the past, this was believed to be indicative of moult state; green crabs havingExpand

Chela loss in the shore crab Carcinus maenas (Crustacea: Brachyura) and its effect on mating success
Field and experimental studies were conducted to determine the incidence of chela loss and its effect on mating success in a population of the shore crab Carcinus maenas (Linnaeus, 1758) inhabitingExpand

Variation in the tidal migratory behaviour and rhythmic light-responsiveness in the shore crab, Carcinus maenas
The distribution of shore crabs, Carcinus maenas (L.), within the intertidal and shallow subtidal zones of a rocky shore in the Menai Strait, North Wales, was recorded regularly by diving throughoutExpand

Dissociation of heart rate and locomotor activity during the expression of rhythmic behaviour in the shore crab Carcinus maenas
Expression of endogenous rhythms in heart rate and locomotor activity were examined in male Carcinus maenas (Brachyura, Crustacea). Heart rate was monitored in immobilised and free moving crabs usingExpand

Tidal and seasonal changes in the temporal and spatial distribution of foraging Carcinus maenas in the weakly tidal littoral zone of Kerteminde Fjord, Denmark
Seasonal and tidal changes in foraging actlvity of the shore crab Carcinus maenas were investigated from August 1992 to May 1993 in Kerteminde Fjord, Funen, Denmark. Foraging activity was 15 to 20Expand

Circatidal variability in the behavioural responses of a sandbeach isopod Eurydice pulchra (Leach) to orientational cues
Abstract Spontaneous, phasic changes in the behavioural responses of freshly collected Eurydice pulchra (Leach) (Isopoda;Crustacea) to light and water flow were studied in the laboratory and relatedExpand

Size‐related mating success in the shore crab Carcinus maenas (Crustacea: Brachyura)
The relationship between the size of a given mating male Carcinus maenas (L.) (Brachyura, Portunidae) and the size of the female with which it was paired was studied for 1248 pairs of crabs collectedExpand

Evidence for multiple, cue-specific circatidal clocks in the shore crab Carcinus maenas
In experiments using a six-chambered combined actograph and tidal simulator, arrhythmic Carcinus maenas (L.) were exposed for 50 h to artificial tidal cycles of salinity, temperature and pressureExpand

Spatial variability in the population structure of the shore crab Carcinus maenas (Crustacea: Brachyura) in a shallow-water, weakly tidal fjord
The spatial vanabllity in population structure of the shore crab Carcinus maenas was studied In a shallo\v-water fiord in the lsland of Fyn, Denmark The fjord compnses an enclosed area whlch isExpand

The use of cardiac monitoring in the assessment of mercury toxicity in the subtropical pebble crab Gaetice depressus (Brachyura: Grapsidae: Varuninae)
Heart rates were monitored in the pebble crab, Gaetice depressus using a non-invasive, computer aided cardiac monitoring system. A high degree of intra- and interindividual variability was observed,Expand
