Genetic diversity
 
Research study 1
 

map showing collecting sites for weathervane scallops in study of their genetic diversityLittle research has been done on genetic diversity in west-coast scallops.  However, a study on weathervane scallops Patinopecten caurinus in the Gulf of Alaska and southeastern Bering Sea by researchers primarily from the Alaska Department of Fish and Game reveals little genetic differentiation.  Weathervane scallops, as other west-coast scallop species, produce a veliger larva that is free-swimming and that disseminates widely for several weeks.  Gaffney et al. 2010 Can J Fish Aquat Sci 67: 1827.photograph of weathervane scallop Patinopecten caurinus

 

 

 


NOTE
surveyed at nuclear loci with allozyme, microsatellite, and single nucleotide polymorphism (SNP) methods, and at mitochondrial (mt)DNA loci with SNPs and nucleotide sequencing

NOTE  the species is touted as being the largest scallop in the world (shell length to 25cm). It is hard to find any information on the origin of its common name. Perhaps it, or its ecological homologue Pecten maximus in Europe (to 17cm), when fastened to a stick on the roof was large enough to show wind direction
