| Summary: | Local adaption through ecological niche specialization can lead to genetic structure between and within populations. In the Northeast Pacific, killer whales (Orcinus orca) of the same population have uniform specialized diets that are non-overlapping with other sympatric, genetically divergent and socially isolated killer whale ecotypes. However, killer whales in Iceland show intra-population variation of isotopic niches and observed movement patterns: some individuals appear to specialise on herring and follow it year-round while others feed upon herring only seasonally or opportunistically. We investigated genetic differentiation among Icelandic killer whales with different isotopic signatures and observed movement patterns. This information is key for management and conservation purposes but also for better understanding how niche specialization drives genetic differentiation. Photo-identified individuals (N = 61) were genotyped for 22 microsatellites and a 611 bp portion of the mitochondrial control ... : Mitochondrial haplotype and microsatellite genotypes of killer whales in IcelandThis dataset includes mitochondrial haplotype (mtDNA) and 22 microsatellite genotypes from 61 killer whales (Orcinus orca) collected during dedicated fieldwork in Icelandic waters. 0 represents missing values. mtDNA sequences were visually inspected using the software FinchTV v1.4.0 and individual mtDNA haplotype was determined using the software BioEdit v7.2.5. Peak Scanner Software 2 was used to size each microsatellite allele.Tavares et al 2018 Ecology and Evolution.csv ... |
