The use of the dog-whelk, Nucella lapillus , as an indicator of tributyltin (TBT) contamination
The incidence and intensity of imposex have since increased markedly in the same populations and that the phenomenon is widespread around south-west England is demonstrated.
Sex Change in the Female Dog-Whelk, Nucella Lapillus , Induced by Tributyltin from Antifouling Paints
Both field and laboratory observations have provided conclusive evidence that imposex in N. lapillus is initiated by tributyltin (TBT), used as a biocide in antifouling paints, at concentrations in water of less than 1 ng Sn/1.

It seems likely that the sperm whale is obtaining 77% of its food by swimming through luminous shoals of slow-swimming, neutrally bouyant squids and only about 23% by chasing faster swimming, larger cephalopods.
Nassarius reticulatus (Nassariidae: Gastropoda) as an indicator of tributyltin pollution before and after TBT restrictions
It was concluded that N. reticulatus is a useful alternative to N. lapillus as an imposex-based TBT indicator at contaminated sites, however, when environmental TBT concentrations are declining fairly rapidly, analysis of N. ReticULatus tissues provides a far better indication of change than measurements of population imposex.
Evaluation of the comet assay as a method for the detection of DNA damage in the cells of a marine invertebrate, Mytilus edulis L. (Mollusca: Pelecypoda).
Variation of karyotype composition and genome size in some muricid gastropods from the Northern Hemisphere
Members of the Muricidae in the Northern Hemisphere show striking variation in chromosome number, and differences in the proportions of heterochromatin and packing ratios of the metaphase chromosomes are discussed with reference to the evolution and biogeography of the family.

Chromosomal and nuclear characteristics of deep-sea hydrothermal-vent organisms: correlates of increased growth rate
This is the first direct evidence of differences in cell-division rate between vent and non-vent species, which undoubtedly reflects contrasting conditions relating to food availability and temporal stability in these two deep-sea environments.
