Genetic relationships of Korean Ocenebrine species (Gastropoda: Prosobranchia: Muricidae) [PDF]

open access: yesKorean Journal of Biological Sciences, 1999
Allele frequencies in twenty‐two populations from nine Korean muricid species of five genera (Rapaninae and Ocenebrinae) were analyzed genetically using 13 loci from 11 allozyme systems. The clustering patterns of these species were basically consistent with traditional groupings to two subfamilial categories based on shell and radula morphologies ...

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 ...
