Following recognition of effects in the 1980s, tributyltin (TBT) has been monitored at sites in the English Channel to evaluate the prognosis for biota - spanning the introduction of restrictions on TBT use on small boats and the recent phase-out on

Estuarine clams Scrobicularia plana were sampled from 108 intertidal locations around the English Channel and adjacent areas. Although S. plana is believed to be a strict gonochorist, 58% of the populations sampled included intersexed individuals (de

A range of tissue and cell types from adult and juvenile stages of vent- and non-vent-dwelling deep-sea and shallow-water organisms were compared for signs of cell division, in preparation for a cytogenetic study of the different groups. Virtually al

Suspension-feeding behaviour in the scallop Chlamys farreri of 72±1 mm shell length was studied in response to wide variations in the amount and composition of suspended seston. Clearance rates (CR; l h−1) with which scallops removed all particles

An earlier study of metals in the polychaete Owenia fusiformis showed that individuals within intertidal populations were remarkably variable in terms of whole-body concentrations of zinc and copper. Four populations have now been studied, two in sou

The marine environment receives a wide variety of chemical inputs, many of which have the potential to damage DNA or interfere with the process of cell division. Here we describe a new assay based on the early embryo and larval stages of a planktonic

Stomach contents from an adult male sperm whale (Physeter catodori) stranded at Penzance, Cornwall, included a total of 125 upper and 110 lower beaks (mandibles) of cephalopods. All but two of the cephalopod species represented by lower beaks were oc
