The decline of the gastropod Nucella lapillus
around south west England: evidence for the effect of tributyltin from antifouling paints.
34-mm threshold for drill hole diameter for smaller Nucella lapillus
than 5 mm and above 5 mm preying on Mytilus trossulus and Mytilus edulis.
pugilis (Colton, 1905; Galindo-Perez, 2009) and other snails like Buccinun undatum (Hallers-Tjabbers, 1979), Nucella lapillus
(Son & Hughes, 2000), Pomacea canaliculata (Avaca et al.
Reproductive failure in populations of the dog-whelk, Nucella lapillus
, caused by imposex induced by tributyltin from antifouling paints.
Several studies on the morphology and morphometry of the sagitta, lapillus
and asteriscus otoliths have already been made (VOLPEDO; ECHEVERRIA, 2000; BAREMORE; BETHEA 2006; CAMPANA, 2004; FURLANI et al.
Recovery in populations of dog whelk Nucella lapillus
These canals form chambers containing otoliths, the lapillus
is included in the utriculus (figure 1), the sagitta in the sacculus and the asteriscus is included in the lagena (figure 2).
The most striking finding, which has not been reported previously in Nucella lapillus
, the Atlantic dogwhelk, is that shell length increased at all 19 sites where samples were taken.
Ademas de lapas y bigaros, se ha documentado un unico ejemplar de Nucella lapillus
Littorina littorea, Littorina saxatilis, Nucella lapillus
y familia Neritidae.
Hughes and Dunkin (1984) describe a similar behavior in the gastropod Nucella lapillus
, which consumes the digestive gland and discards the mantle and foot when preying on mytilids.
