Abstract Objective The objectives of this work are to isolate, develop, and characterize polymorphic microsatellite markers for use in Greenland sharks (Somniosus microcephalus). Results Thirteen microsatellite loci were successfully amplified and yielded multi-locus genotypes for 36 S. microcephalus individuals from Grise Fjord (n = 16) and Svalbard (n = 20). Each locus yielded between 2 and 9 alleles and observed heterozygosity ranged from 0.11 to 0.70 when estimated across both sites. One locus and three loci deviated from HWE following Bonferroni correction, for individuals sampled from Grise Fjord and Svalbard, respectively. Cross-amplification was successful at every locus for five of the ten S. pacificus individuals.

Abstract Objective The objectives of this research are to isolate, develop and characterize polymorphic microsatellite markers for use in Greenland sharks ( Somniosus microcephalus ). Despite utility in population analyses, microsatellite markers have not been previously developed for this species. Development of these markers, and successful amplification in closely related Pacific sleeper sharks ( S. pacificus ), will facilitate research in the genetic variation of contemporary and future populations of sleeper shark species. Results Thirteen microsatellite loci were successfully amplified and yielded multi-locus genotypes for 32 S. microcephalus individuals from Grise Fjord (n = 16) and Svalbard (n = 20). Each locus yielded between 2 to 9 alleles and observed heterozygosity ranged from 0.11 to 0.70 when estimated across both sites. One locus and three loci deviated from HWE following Bonferroni correction, for individuals sampled from Grise Fjord and Svalbard, respectively. Cross-amplification was successful at every locus for five of the ten S. pacificus individuals.

Polymorphic Microsatellite

ABSTRACT Data on 15 novel microsatellite loci from the Neotropical fish Bryconamericus aff. iheringii are presented here. Analyses of 32 individuals from four different streams revealed 192 different alleles, ranging from four to 32 alleles per locus (mean of 12.8 per locus). Observed and expected heterozygosities ranged from 0.094 to 0.813 and 0.205 to 0.952, respectively. These loci showed high polymorphic information content and will be a resource for genetic studies of B. aff. iheringii. Furthermore, several loci also amplified other small Neotropical Characidae (Piabarchus stramineus and Piabina argentea) and should be useful for these species.
