Data from: Large-scale parentage analysis reveals reproductive patterns and heritability of spawn timing in a hatchery population of steelhead (Oncorhynchus mykiss)

Alicia Abadía-Cardoso, Eric C. Anderson, Devon E. Pearse & John Carlos Garza
Understanding life history traits is an important first step in formulating effective conservation and management strategies. The use of artificial propagation and supplementation as such a strategy can have numerous effects on the supplemented natural populations and minimizing life history divergence is crucial in minimizing these effects. Here, we use single nucleotide polymorphism (SNP) genotypes for large-scale parentage analysis and pedigree reconstruction in a hatchery population of steelhead, the anadromous form of rainbow trout. Nearly...

C. Scott Baker, Debbie Steel, John Calambokidis, Erin A. Falcone, Ursula Gozález-Peral, Jay Barlow, Alexander M. Burdin, Phillip J. Clapham, John K. B. Ford, Christine M. Gabriele, David Mattila, Janice M. Straley, Barbara L. Taylor, Jorge Urbán, Paul R. Wade, David Weller, Briana H. Witteveen, Manami Yamaguchi, CS Baker, BH Witteveen, E Falcone, BL Taylor, JKB Ford, AM Burdin, PJ Clapham … & JM Straley
We quantified the relative influence of maternal fidelity to feeding grounds and natal fidelity to breeding grounds in humpback whales based on an ocean-wide survey of mitochondrial (mt) DNA diversity in the North Pacific. For 2,193 biopsy samples collected from whales in 10 feeding regions and 8 breeding regions during the winter and summer of 2004 to 2006, we first used microsatellite genotyping (average, 9.5 loci) to identify replicate samples. From sequences of the mtDNA...

Data from: Drifting to oblivion? Rapid genetic differentiation in an endangered lizard following habitat fragmentation and drought

Amy G. Vandergast, Dustin A. Wood, Andrew R. Thompson, Mark Fisher, Cameron W. Barrows & Tyler J. Grant
Aim: The frequency and severity of habitat alterations and disturbance are predicted to increase in upcoming decades, and understanding how disturbance affects population integrity is paramount for adaptive management. Although rarely is population genetic sampling conducted at multiple time points, pre- and post-disturbance comparisons may provide one of the clearest methods to measure these impacts. We examined how genetic properties of the federally threatened Coachella Valley fringe-toed lizard (Uma inornata) responded to severe drought and...

Data from: Natal foraging philopatry in eastern Pacific hawksbill turtles

Alexander R. Gaos, Rebecca L. Lewison, Michael P. Jensen, Michael J. Liles, Ana Henriquez, Sofia Chavarria, Carlos Mario Pacheco, Melissa Valle, David Melero, Velkiss Gadea, Eduardo Altamirano, Perla Torres, Felipe Vallejo, Cristina Miranda, Carolina LeMarie, Jesus Lucero, Karen Oceguera, Didiher Chacón, Luis Fonseca, Marino Abrego, Jeffrey A. Seminoff, Eric E. Flores, Israel Llamas, Rodrigo Donadi, Bernardo Peña … & Daniela Alarcón Ruales
The complex processes involved with animal migration have long been a subject of biological interest and broad-scale movement patterns of many marine turtle populations still remain unresolved. While it is widely accepted that once marine turtles reach sexual maturity they home to natal areas for nesting or reproduction, the role of philopatry to natal areas during other life stages has received less scrutiny, despite widespread evidence across the taxa. Here we report on genetic research...

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

Ian R. Bradbury, Brendan F. Wringe, Beth Watson, Ian Paterson, John Horne, Robert Beiko, Sarah J. Lehnert, Marie Clément, Eric C. Anderson, Nicholas W. Jeffery, Steven Duffy, Emma Sylvester, Martha Robertson & Paul Bentzen
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: 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: Physiological, morphological, and ecological tradeoffs influence vertical habitat use of deep-diving toothed-whales in the Bahamas

Trevor W. Joyce, John W. Durban, Diane E. Claridge, Charlotte A. Dunn, Holly Fearnbach, Kim M. Parsons, Russel D. Andrews & Lisa T. Ballance
Dive capacity among toothed whales (suborder: Odontoceti) has been shown to generally increase with body mass in a relationship closely linked to the allometric scaling of metabolic rates. However, two odontocete species tagged in this study, the Blainville’s beaked whale Mesoplodon densirostris and the Cuvier’s beaked whale Ziphius cavirostris, confounded expectations of a simple allometric relationship, with exceptionally long (mean: 46.1 min & 65.4 min) and deep dives (mean: 1129 m & 1179 m), and...

Data from: Habitat modeling of Irrawaddy dolphins (Orcaella brevirostris) in the eastern Gulf of Thailand

Justine Jackson-Ricketts, Chalatip Junchompoo, Ellen Hines, Elliot Hazen, Louisa Ponnampalam, Anoukchika Ilangakoon & Somchai Monanunsap
Aim: The Irrawaddy dolphin (Orcaella brevirostris) is an endangered cetacean found throughout Southeast Asia. The main threat to this species is human encroachment, led by entanglement in fishing gear. Information on this data-poor species’ ecology and habitat use is needed to effectively inform spatial management. Location: We investigated the habitat of a previously unstudied group of Irrawaddy dolphins in the eastern Gulf of Thailand, between the villages of Laem Klat and Khlong Yai, in Trat...

Winter-run Chinook salmon resource selection function 2020

Peter Dudley
We use historic aerial redd surveys of Sacramento River winter-run Chinook salmon, coupled with 2D hydraulic modeling, and apply multivariable polynomial, logistic regression to calculate spawning resource selection functions (RSFs) based on water velocity and depth, and examine their interactions with water temperature. Our methods resulted in univariate and multivariate resource selection functions with interactions between both velocity and depth preference with changing temperature. Preferred depth increased and preferred velocity decreased with increasing temperature.

Triennial migration and philopatry in the critically endangered soupfin shark (Galeorhinus galeus)

Andrew Nosal, Daniel Cartamil, Arnold Ammann, Lyall Bellquist, Noah Ben-Aderet, Kayla Blincow, Echelle Burns, Eric Chapman, Ryan Freedman, Peter Klimley, Ryan Logan, Christopher Lowe, Brice Semmens, Connor White & Philip Hastings
Globally, one-quarter of shark and ray species is threatened with extinction due to overfishing. Effective conservation and management can facilitate population recoveries; however, these efforts depend on robust data on movement patterns and stock structure, which are lacking for many threatened species, including the Critically Endangered soupfin shark (Galeorhinus galeus), a circumglobal coastal-pelagic species. Using passive acoustic telemetry, we continuously tracked 34 mature female soupfin sharks, surgically implanted with coded acoustic transmitters, for seven years...

Emma L. Carroll, Michael R. McGowen, Morgan L. McCarthy, Felix G. Marx, Natacha Aguilar De Soto, Merel L. Dalebout, Sascha Dreyer, Oscar E. Gaggiotti, Sabine S. Hansen, Anton Van Helden, Aubrie B. Onoufriou, Robin W. Baird, C. Scott Baker, Simon Berrow, Danielle Cholewiak, Diane Claridge, Rochelle Constantine, Nicholas J. Davison, Catarina Eira, R. Ewan Fordyce, John Gatesy, G. J. Greg Hofmeyr, Vidal Martin, James G. Mead, Antonio A. Mignucci-Giannoni … & Morten T. Olsen
Earth’s deep oceans remains less well understood than the surface of Mars. Beaked whales (ziphiids) are among the most visible inhabitants of the abyss, due to their large size and worldwide distribution, yet their diversity and ecology remain obscure. We combine genomic and morphometric analyses to reveal a new Southern Hemisphere ziphiid species, Ramari’s beaked whale, Mesoplodon eueu, whose name is linked to the Indigenous people of the lands from which the species holotype and...

Data for: Social-ecological vulnerability of fishing communities to climate change: a U.S. West Coast case study

Laura Koehn, Laura Nelson, Jameal Samhouri, Karma Norman, Michael Jacox, Alison Cullen, Jerome Fiechter, Mercedes Pozo Buil & Phillip Levin
Climate change is already impacting coastal communities, and ongoing and future shifts in fisheries species productivity from climate change have implications for the livelihoods and cultures of coastal communities. Harvested marine species in the California Current Large Marine Ecosystem support U.S. West Coast communities economically, socially, and culturally. Ecological vulnerability assessments exist for individual species in the California Current but ecological and human vulnerability are linked and vulnerability is expected to vary by community. Here,...

Data from: A worldwide perspective on the population structure and genetic diversity of bottlenose dolphins (Tursiops truncatus) in New Zealand

Gabriela Tezanos-Pinto, Charles S Baker, Kirsty Russell, Karen Martien, Robin Baird, Alistair Hutt, Gregory Stone, Antonio A Mignucci-Giannoni, Susana Caballero, Tetsuya Endo, Shane Lavery, Marc Oremus, Carlos Olavarria & Claire Garrigue
Bottlenose dolphins (Tursiops truncatus) occupy a wide range of coastal and pelagic habitats throughout tropical and temperate waters worldwide. In some regions, "inshore" and "offshore" forms or ecotypes differ genetically and morphologically, despite no obvious boundaries to interchange. Around New Zealand, bottlenose dolphins inhabit 3 coastal regions: Northland, Marlborough Sounds, and Fiordland. Previous demographic studies showed no interchange of individuals among these populations. Here, we describe the genetic structure and diversity of these populations using...

Data from: Quantifying physiological influences on otolith microchemistry

Anna M. Sturrock, Ewan Hunter, J. Andrew Milton, Edinburgh Ion Microprobe Facility, Rachel C. Johnson, Colin P. Waring & Clive N. Trueman
1. Trace element concentrations in fish earstones (“otoliths”) are widely used to discriminate spatially discrete populations or individuals of marine fish, based on a commonly held assumption that physiological influences on otolith composition are minor, and thus variations in otolith elemental chemistry primarily reflect changes in ambient water chemistry. 2. We carried out a long-term (1-yr) experiment, serially sampling seawater, blood plasma and otoliths of mature and immature European plaice (Pleuronectes platessa L.) to test...

Data from: Influences of past climatic changes on historical population structure and demography of a cosmopolitan marine predator, the common dolphin (genus Delphinus)

Ana Amaral, Luciano Beheregaray, Kerstin Bilgmann, Luís Freitas, Kelly Robertson, Marina Sequeira, Karen Stockin, M. M. Coelho & Luciana Möller
Climatic oscillations during the Pleistocene have greatly influenced the distribution and connectivity of many organisms, leading to extinctions but also generating biodiversity. While the effects of such changes have been extensively studied in the terrestrial environment, studies focusing on the marine realm are still scarce. Here we used sequence data from one mitochondrial and five nuclear loci to assess the potential influence of Pleistocene climatic changes on the phylogeography and demographic history of a cosmopolitan...

Data from: What influences the worldwide genetic structure of sperm whales (Physeter macrocephalus)?

Alana Alexander, Debbie Steel, Kendra Hoekzema, Sarah L. Mesnick, Daniel Engelhaupt, Iain Kerr, Roger Payne & Charles Scott Baker
The interplay of natural selection and genetic drift, influenced by geographic isolation, mating systems and population size, determines patterns of genetic diversity within species. The sperm whale provides an interesting example of a long-lived species with few geographic barriers to dispersal. Worldwide mtDNA diversity is relatively low, but highly structured among geographic regions and social groups, attributed to female philopatry. However, it is unclear whether this female philopatry is due to geographic regions or social...

Data from: Integrating lipid storage into general representations of fish energetics

Benjamin T. Martin, Ron Heintz, Eric M. Danner & Roger M. Nisbet
Fish, even of the same species, can exhibit substantial variation in energy density (energy per unit wet weight). Most of this variation is due to differences in the amount of storage lipids. In addition to their importance as energy reserves for reproduction and for survival during unfavourable conditions, the accumulation of lipids represents a large energetic flux for many species, so figuring out how this energy flux is integrated with other major energy fluxes (growth,...

Data from: Staying close to home? Genetic differentiation of rough-toothed dolphins near oceanic islands in the central Pacific Ocean

G. Renee Albertson, Robin W. Baird, Marc Oremus, M. Michael Poole, Karen K. Martien & C. Scott Baker
Rough-toothed dolphins have a worldwide tropical and subtropical distribution, yet little is known about the population structure and social organization of this typically open-ocean species. Although it has been assumed that pelagic dolphins range widely due to the lack of apparent barriers and unpredictable prey distribution, recent evidence suggests rough-toothed dolphins exhibit fidelity to some oceanic islands. Using the most comprehensively extensive dataset for this species to date, we assess the isolation and interchange of...

Data from: Genetic assignment with isotopes and habitat suitability (GAIAH), a migratory bird case study

Kristen C. Ruegg, Eric C. Anderson, Ryan J. Harrigan, Kristina L. Paxton, Jeffrey F. Kelly, Frank Moore & Thomas B. Smith
1. Identifying migratory connections across the annual cycle is important for studies of migrant ecology, evolution, and conservation. While recent studies have demonstrated the utility of high-resolution SNP-based genetic markers for identifying population-specific migratory patterns, the accuracy of this approach relative to other intrinsic tagging techniques has not yet been assessed. 2. Here, using a straightforward application of Bayes' Rule, we develop a method for combining inferences from high-resolution genetic markers, stable isotopes, and habitat...

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...

Data from: Discovery and characterization of single nucleotide polymorphisms in two anadromous alosine fishes of conservation concern

Diana S. Baetscher, Daniel J. Hasselman, Kerry Reid, Eric P. Palkovacs & John Carlos Garza
Freshwater habitat alteration and marine fisheries can affect anadromous fish species, and populations fluctuating in size elicit conservation concern and coordinated management. We describe the development and characterization of two sets of 96 single nucleotide polymorphism (SNP) assays for two species of anadromous alosine fishes, alewife and blueback herring (collectively known as river herring), that are native to the Atlantic coast of North America. We used data from high-throughput DNA sequencing to discover SNPs and...
