Data from: Structure and phylogeography of two tropical predators, spinner (Stenella longirostris) and pantropical spotted (S attenuata) dolphins, from SNP data

Matthew S. Leslie & Phillip A. Morin
Little is known about global patterns of genetic connectivity in pelagic dolphins, including how circumtropical pelagic dolphins spread globally following the rapid and recent radiation of the subfamily delphininae. In this study, we tested phylogeographic hypotheses for two circumtropical species, the spinner dolphin (Stenella longirostris) and the pantropical spotted dolphin (Stenella attenuata), using >3,000 nuclear DNA single nucleotide polymorphisms (SNPs) in each species. Analyses for population structure indicated significant genetic differentiation between almost all subspecies...

Data from: Potential limitations of behavioral plasticity and the role of egg relocation in climate change mitigation for a thermally-sensitive endangered species

Anthropogenic climate change is widely considered a major threat to global biodiversity, such that the ability of a species to adapt will determine its likelihood of survival. Egg-burying reptiles that exhibit temperature-dependent sex determination, such as critically endangered hawksbill turtles (Eretmochelys imbricata), are particularly vulnerable to changes in thermal regimes because nest temperatures affect offspring sex, fitness, and survival. It is unclear whether hawksbills possess sufficient behavioral plasticity of nesting traits (i.e., redistribution of nesting...

Data from: Mesoscale activity facilitates energy gain in a top predator

Briana Abrahms, Kylie L. Scales, Elliott L. Hazen, Steven J. Bograd, Robert S. Schick, Patrick W. Robinson & Daniel P. Costa
How animal movement decisions interact with the distribution of resources to shape individual performance is a key question in ecology. However, links between spatial and behavioural ecology and fitness consequences are poorly understood because the outcomes of individual resource selection decisions, such as energy intake, are rarely measured. In the open ocean, mesoscale features (~10-100 km) such as fronts and eddies can aggregate prey and thereby drive the distribution of foraging vertebrates through bottom-up biophysical...

Data from: Genotyping-by-sequencing of genome-wide microsatellite loci reveals fine-scale harvest composition in a coastal Atlantic salmon fishery

Individual assignment and genetic mixture analysis are commonly utilized in contemporary wildlife and fisheries management. Although microsatellite loci provide unparalleled numbers of alleles per locus, their use in assignment applications is increasingly limited. However, next-generation sequencing, in conjunction with novel bioinformatic tools allows large numbers of microsatellite loci to be simultaneously genotyped, presenting new opportunities for individual assignment and genetic mixture analysis. Here we scanned the published Atlantic salmon genome to identify 706 microsatellite loci,...

Data from: Host‐derived population genomics data provides insights into bacterial and diatom composition of the killer whale skin

Rebecca Hooper, Jaelle C. Brealey, Tom Van Der Valk, Antton Alberdi, John W. Durban, Holly Fearnbach, Kelly M. Robertson, Robin W. Baird, M. Bradley Hanson, Paul Wade, M. Thomas P. Gilbert, Philip A. Morin, Jochen B. W. Wolf, Andrew D. Foote, Katerina Guschanski & Phillip A. Morin
Recent exploration into the interactions and relationship between hosts and their microbiota has revealed a connection between many aspects of the host's biology, health and associated micro‐organisms. Whereas amplicon sequencing has traditionally been used to characterize the microbiome, the increasing number of published population genomics data sets offers an underexploited opportunity to study microbial profiles from the host shotgun sequencing data. Here, we use sequence data originally generated from killer whale Orcinus orca skin biopsies...

Data from: Demography or selection on linked cultural traits or genes? Investigating the driver of low mtDNA diversity in the sperm whale using complementary mitochondrial and nuclear genome analyses

Phillip A. Morin, Andrew D. Foote, Charles Scott Baker, Brittany L. Hancock-Hanser, Kristin Kaschner, Bruce R. Mate, Sarah L. Mesnick, Victoria L. Pease, Patricia E. Rosel & Alana Alexander
Mitochondrial DNA has been heavily utilized in phylogeography studies for several decades. However, underlying patterns of demography and phylogeography may be misrepresented due to coalescence stochasticity, selection, variation in mutation rates, and cultural hitchhiking (linkage of genetic variation to culturally transmitted traits affecting fitness). Cultural hitchhiking has been suggested as an explanation for low genetic diversity in species with strong social structures, counteracting even high mobility, abundance and limited barriers to dispersal. One such species...

Data from: Colonizing the wild west: low diversity of complete mitochondrial genomes in western North Pacific killer whales suggests a founder effect

Olga A. Filatova, Ekaterina A. Borisova, Ilya G. Meshchersky, Maria D. Logacheva, Nataliia V. Kuzkina, Olga V. Shpak, Phillip A. Morin, Erich Hoyt & Ilya G Meschersky
In the North Pacific, fish-eating R-type “resident” and mammal-eating T-type “transient” killer whales do not interbreed and differ in ecology and behavior. Full-length mitochondrial genomes (about 16.4 kbp) were sequenced and assembled for 12 R-type and 14 T-type killer whale samples from different areas of the western North Pacific. All R-type individuals had the same haplotype, previously described for R-type killer whales from both eastern and western North Pacific. However, haplotype diversity of R-type killer...

Data from: Maternal diet and age alter direct and indirect relationships between life history traits across multiple generations

Jared M. Goos, Cameron J. Swain, Stephan B. Munch & Matthew R. Walsh
1. Maternal age has important consequences for offspring fitness, with influences on size, development, and reproductive schedules. Such maternal age effects may be driven by differential provisioning of resources, yet little is known about the role of environmental supply of nutritional resources in mediating such effects. 2. We tested the influence of limiting nutritional resource, dietary phosphorus (P), on maternal age effects across multiple generations by examining the potential interactive effects of maternal nutrition and...
