The circalunidian hypothesis that tidal rhythms in coastal animals are controlled by two lunar-day (c.24.8 h) oscillators coupled in antiphase is challenged. Rhythmic locomotor activity patterns ofExpand

Tidal and Diurnal Rhythms of Locomotory Activity in Carcinus Maenas (L.)
1. Spontaneous locomotory activity was recorded continuously for several days in Carcinus maenas (L.). 2. A complex rhythm was observed which could be analysed into two components, one of diurnalExpand

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

Chronobiology: implications for marine resource exploitation and management
Chronobiology began as a curiosity-driven science and now impacts significantly on the science of medicine through medical rhythm research and chronotherapeutics. However, whilst it has long beenExpand

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

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

Endogenous rhythms of circatidal swimming activity in the estuarine copepod Eurytemora affinis (Poppe)
Abstract Under constant conditions in the laboratory the estuarine copepod Eurytemora affinis (Poppe) displays an endogenous circatidal swimming rhythm. The phasing of peak endogenous activity variesExpand

Seasonal changes in a population of Carcinus maenas (L.) in the littoral zone
In previous work it has been shown that Carcinus maenas (L.) exhibits rhythmic patterns of locomotor activity with periods of greatest activity coinciding with the times of high tide and with theExpand
