Neogastropod (Mollusca, Gastropoda) phylogeny: A step forward with mitogenomes. [PDF]

Zool Scr, 2022
Abstract The Neogastropoda (Mollusca, Gastropoda) encompass more than 15,000 described species of marine predators, including several model organisms in toxinology, embryology and physiology. However, their phylogenetic relationships remain mostly unresolved and their classification unstable.

Origin of the tropical–polar biodiversity contrast

Global Ecology and Biogeography, Volume 31, Issue 6, Page 1207-1227, June 2022., 2022
Abstract Aim The aim was to investigate the evolutionary origins of the striking biodiversity contrast between high‐ and low‐latitude regions in the present day. Is this a relatively recent phenomenon, causally linked in some way to the greenhouse–icehouse transition and onset of global cooling c.

Spermatogenesis in the marine snail Adelomelon ancilla (Volutidae) from Patagonia [PDF]

Journal of Molluscan Studies, 2011
This study describes euspermatogenesis and paraspermatogenesis in Adelomelon ancilla (Volutidae) and compares them with the same processes in other caenogastropods. Spermatogenesis in A. ancilla followed the general developmental pattern of caenogastropods.

THE NEOGENE VOLUTIDAE (GASTROPODA: NEOGASTROPODA) FROM THE PACIFIC COAST OF CHILE

Journal of Paleontology, 2007
Abstract Fourteen species of Volutidae are recognized from the Neogene of central to southern Chile. Seven species are known from previous descriptions: Voluta triplicata, V. alta, V. domeykoana, V. obesa, V. vidali, Proscaphella taverai, and Adelomelon reconditus. A neotype is designated for Voluta alta.

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

, 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.

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

Paleoceanography 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 ...
