Oxidative stress indicators in populations of the gastropod Buccinanops globulosus affected by imposex [PDF]

open access: yes, 2015
The gastropod Buccinanops globulosus is commonly used as a bioindicator of tributyltin (TBT) contamination due to its high imposex incidence in maritime traffic areas. The aim of this study was to evaluate both oxidative stress in B.

Pseudo-imposex; male features in female volutes not TBT-induced (Gastropoda: Volutidae) [PDF]

open access: yesContributions to Zoology, 2008
The occurrence of a penis in female gastropods of the super-family Muricoidea (infraorder Neogastropoda) has commonly been accepted as an indicator of tributyltin (TBT) pollution. Some species seem less sensitive than others, and one belonging to the family Columbellidae has been reported that it lacks the imposex response.

Approaching the Miocene Climatic Optimum in Patagonia (Southern Argentina): Temperature Seasonality and a Potential Role for the Opening Drake Passage

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 6, June 2025.
Abstract The Miocene Epoch (23.03–5.33 Ma) is receiving increased attention because estimated pCO2 and its associated warmth is comparable to projections over the next century. Well‐constrained sea‐surface temperatures in the tropics and northern latitudes express amplified warming during the Miocene Climatic Optimum (MCO; 16.9–14.7 Ma), yet data from ...

Eocene gastropods of the New Forest, UK

open access: yesGeology Today, Volume 41, Issue 1, Page 26-37, January/February 2025.
Gastropods expanded into niches vacated by both terrestrial and marine organisms following the end‐Cretaceous mass extinction, to become one of the dominant mollusc groups of the Cenozoic. The Selsey Formation of Eocene age was deposited within a shallow marine embayment across the Hampshire Basin (southern England) and contains a particularly diverse ...
