The use of the dog-whelk, Nucella lapillus , as an indicator of tributyltin (TBT) contamination
TLDR
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
TLDR
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.
The diet of sperm whales (Physeter macrocephalus Linnaeus 1758) off the Azores.
TLDR
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
TLDR
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.
Variation of karyotype composition and genome size in some muricid gastropods from the Northern Hemisphere
TLDR
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.
The Stomach Contents of A Risso's Dolphin (Grampus Griseus) Stranded at Thurlestone, South Devon
L'examen du contenu stomacal de G.g. permet d'apporter quelques precisions sur sa voie de migration avant l'echouage
Chromosomal and nuclear characteristics of deep-sea hydrothermal-vent organisms: correlates of increased growth rate
TLDR
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.
