Early Miocene (Burdigalian) Gastropod Faunas of Vareh Zard section, North of Pole-Dokhtar, (Lorestan, Iran)
A total 7 species and 13 genera of marine gastropod assemblages are reported for the first time from the Varehh Zard section (Asmari Formation), north of Pole Dokhtar, Lorestan Basin. The section under study, the Asmari Formation, lies between the Shahbazam Formation at the base and Gachsaran Formation at the top. According to the distribution of index foraminifera, the Asmari Formation is Earl...
متن کاملVolatility in the effective size of a freshwater gastropod population
Despite the utility of gastropod models for the study of evolutionary processes of great generality and importance, their effective population size has rarely been estimated in the field. Here, we report allele frequency variance at three allozyme-encoding loci monitored over 7 years in a population of the invasive freshwater pulmonate snail Physa acuta (Draparnaud 1805), estimating effective p...

متن کاملThe Heritability of Shell Morphometrics in the Freshwater Pulmonate Gastropod Physa
The cosmopolitan freshwater pulmonate snail Physa acuta hybridizes readily with Physa carolinae in the laboratory, although their F1 progeny are sterile. The two species differ qualitatively in shell shape, the former bearing a more globose shell and the latter more fusiform. We performed a hybridization experiment, measuring a set of 14 traditional (linear) and landmark-based shell morphologic...
