Description
Summary:Oscillations in the Earth’s temperature and the subsequent retreating and advancing of ice-sheets around the polar regions are thought to have played an important role in shaping the distribution and genetic structuring of contemporary high-latitude populations. After the Last Glacial Maximum (LGM), retreating of the ice-sheets would have enabled early colonizers to rapidly occupy suitable niches to the exclusion of other conspecifics, thereby reducing genetic diversity at the leading-edge. Bottlenose dolphins (genus Tursiops) form distinct coastal and pelagic ecotypes, with finer scale genetic structuring observed within each ecotype. We reconstruct the post-glacial colonization of the Northeast Atlantic (NEA) by bottlenose dolphins using habitat modelling and phylogenetics. The AquaMaps model hindcasted suitable habitat for the LGM in the Atlantic lower latitude waters and parts of the Mediterranean Sea. The time-calibrated phylogeny, constructed with 86 complete mitochondrial genomes including 30 ... : Delphinids_SABD1_SA99_gene_regions_concatenatedAlignment FASTA-file of concatenated mtDNA genes of 18 delphinids and two Tursiops spp.Tursiops_gene_regions_concatenatedAlignment FASTA-file of concatenated mtDNA genes of 86 Tursiops spp.Tursiops_Steno_bredanensis_aligned_whole_mtDNAFASTA-alignment file of whole mtDNA Tursiops spp. and Steno bredanensisBEAST2_Delphinid_Strict_clock_3rd_codonsBEAST2 xml file to run a strict clock model with delphinids using 3rd codon positions of mtDNA genesStarBEAST2_Tursiops_input_3rd_codonsStarBEAST2 xml file to run a strict clock model with Tursiops spp. using 3rd codon positions of mtDNA genes ...
