Temporal trends and effects of noise on upsweep calls of Eastern South Pacific southern right whales

Ellen Jacobs, Rafaela Landea & Laela Sayigh
Eastern South Pacific southern right whales (ESPSRW) are a subpopulation of southern right whales (Eubalaena australis) off the coasts of Peru and Chile recognized by the International Union for the Conservation of Nature (IUCN) as critically endangered as a result of heavy whaling efforts in the late 18th to 20th centuries. Most recent population estimates put their numbers around 50 individuals. To test for the efficacy of passive acoustic monitoring of this population, we recorded...

Data from: The genomic landscape of rapid repeated evolutionary adaptation to toxic pollution in wild fish

Noah M. Reid, Dina A. Proestou, Bryan W. Clark, Wesley C. Warren, John K. Colbourne, Joseph R. Shaw, Sibel I. Karchner, Mark E. Hahn, Diane Nacci, Marjorie F. Oleksiak, Douglas L. Crawford & Andrew Whitehead
Atlantic killifish populations have rapidly adapted to normally lethal levels of pollution in four urban estuaries. Through analysis of 384 whole killifish genome sequences and comparative transcriptomics in four pairs of sensitive and tolerant populations, we identify the aryl hydrocarbon receptor–based signaling pathway as a shared target of selection. This suggests evolutionary constraint on adaptive solutions to complex toxicant mixtures at each site. However, distinct molecular variants apparently contribute to adaptive pathway modification among tolerant...

Data from: Evidence of lasting impact of the Deepwater Horizon oil spill on a deep Gulf of Mexico coral community

Pen-Yuan Hsing, Bo Fu, Elizabeth A. Larcom, Samantha P. Berlet, Timothy M. Shank, Annette Frese Govindarajan, Alexandra Julia Lukasiewicz, Philip M. Dixon & Charles R. Fisher
A coral community 11 km southwest of the site of the Deepwater Horizon blowout at 1,370 m water depth was discovered 3.5 months after the well was capped on 3 November 2010. Gorgonian corals at the site were partially covered by a brown flocculent material (floc) that contained hydrocarbons fingerprinted to the oil spill. Here we quantify the visible changes to the corals at this site during five visits over 17 months by digitizing images...

Data from: Sex differences and allee effects shape the dynamics of sex-structured invasions

Allison K. Shaw, Hanna Kokko & Michael G. Neubert
The rate at which a population grows and spreads can depend on individual behaviour and interactions with others. In many species with two sexes, males and females differ in key life history traits (e.g. growth, survival, dispersal), which can scale up to affect population rates of growth and spread. In sexually reproducing species, the mechanics of locating mates and reproducing successfully introduce further complications for predicting the invasion speed (spread rate), as both can change...

Data from: A remote-controlled observatory for behavioural and ecological research: a case study on emperor penguins

Sebastian Richter, Richard C. Gerum, Werner Schneider, Ben Fabry, Céline Le Bohec & Daniel P. Zitterbart
1. Long-term photographic recordings of animal populations provide unique insights in ecological and evolutionary processes. However, image acquisition at remote locations under harsh climatic conditions is highly challenging. 2. We present a robust, energetically self-sufficient and remote-controlled observatory designed to operate year-round in the Antarctic at temperatures below -50 °C and wind speeds above 150 km/h. The observatory is equipped with multiple overview cameras and a high resolution steerable camera with a telephoto lens for...

Data from: Going where traditional markers have not gone before: utility of and promise for RAD-sequencing in marine invertebrate phylogeography and population genomics

Adam M. Reitzel, Santiago Herrera, Michael J. Layden, Mark Q. Martindale & Timothy M. Shank
Characterization of large numbers of single-nucleotide polymorphisms (SNPs) throughout a genome has the power to refine the understanding of population demographic history and to identify genomic regions under selection in natural populations. To this end, population genomic approaches that harness the power of next-generation sequencing to understand the ecology and evolution of marine invertebrates represent a boon to test long-standing questions in marine biology and conservation. We employed restriction-site-associated DNA sequencing (RAD-seq) to identify SNPs...

Data from: Reproductive success of a keystone herbivore is more variable and responsive to climate in habitats with lower resource diversity

David T. Iles, Robert F. Rockwell, Dave N. Koons & David N. Koons
1. The effects of climate on wild populations are often channeled through species interactions. Population responses to climate variation can therefore differ across habitats, owing to variation in the biotic community. Theory predicts that consumer demography should be less variable and less responsive to climate in habitats with greater resource diversity. 2. We tested these predictions using a long-term study of breeding lesser snow geese along the western coast of Hudson Bay, Manitoba, Canada. Reproductive...

Data from: Transcriptome and proteome dynamics of a light-dark synchronized bacterial cell cycle

Jacob R. Waldbauer, Sebastien Rodrigue, Maureen L. Coleman & Sallie W. Chisholm
BACKGROUND: Growth of the ocean’s most abundant primary producer, the cyanobacterium Prochlorococcus, is tightly synchronized to the natural 24-hour light-dark cycle. We sought to quantify the relationship between transcriptome and proteome dynamics that underlie this obligate photoautotroph’s highly choreographed response to the daily oscillation in energy supply. METHODOLOGY/PRINCIPAL FINDINGS: Using Illumina RNA-sequencing transcriptomics and mass spectrometry-based quantitative proteomics, we measured timecourses of paired mRNA-protein abundances for 312 genes every 2 hours over a light-dark cycle....

Data from: Early life exposure to low levels of AHR agonist PCB126 (3,3’,4,4’,5-pentachlorobiphenyl) reprograms gene expression in adult brain

Neelakanteswar Aluru, Sibel I. Karchner & Lilah Glazer
Early life exposure to environmental chemicals can have long-term consequences that are not always apparent until later in life. We recently demonstrated that developmental exposure of zebrafish to low, non-embryotoxic levels of 3,3’,4,4’,5-pentachlorobiphenyl (PCB126) did not affect larval behavior, but caused changes in adult behavior. The objective of this study was to investigate the underlying molecular basis for adult behavioral phenotypes resulting from early life exposure to PCB126. We exposed zebrafish embryos to PCB126 during...

Data from: Patterns and persistence of larval retention and connectivity in a marine fish metapopulation

Pablo Saenz-Agudelo, Geoffrey P. Jones, Simon R. Thorrold & Serge Planes
Connectivity, the demographic linking of local populations through the dispersal of individuals, is one of the most poorly understood processes in population dynamics, yet has profound implications for conservation and harvest strategies. For marine species with pelagic larvae, direct estimation of connectivity remains logistically challenging and has mostly been limited to single snapshots in time. Here, we document seasonal and interannual patterns of larval dispersal in a metapopulation of the coral reef fish Amphiprion polymnus....

Data from: Indirect human impacts reverse centuries of carbon sequestration and salt marsh accretion

Tyler C. Coverdale, Caitlin P. Brisson, Eric W. Young, Stephanie F. Yin, Jeffrey P. Donnelly & Mark D. Bertness
Direct and indirect human impacts on coastal ecosystems have increased over the last several centuries, leading to unprecedented degradation of coastal habitats and loss of ecological services. Here we document a two century temporal disparity between salt marsh accretion and subsequent loss to indirect human impacts. Field surveys, manipulative experiments and GIS analyses reveal that crab burrowing weakens the marsh peat base and facilitates further burrowing, leading to bank calving, disruption of marsh accretion, and...

Differential learning by native versus invasive predators to avoid distasteful cleaning mutualists

Lillian Tuttle, Robert Lamb & Allison Stringer
1. Cleaning symbioses on coral reefs are mutually beneficial interactions between two individuals, in which a ‘cleaner’ removes and eats parasites from the surface of a ‘client’ fish. A suite of behavioural and morphological traits of cleaners signal cooperation with co-evolved species, thus protecting the cleaner from being eaten by otherwise predatory clients. However, it is unclear whether cooperation between cleaners and predatory clients is innate or learned, and therefore whether an introduced predator might...

Data from: Developmental exposure to PCB153 (2,2’,4,4’,5,5’-hexachlorobiphenyl) alters circadian rhythms and the expression of clock and metabolic genes

Neel Aluru, Keegan Krick, Adriane McDonald & Sibel Karchner
Polychlorinated biphenyls (PCBs) are highly persistent and ubiquitously distributed environmental pollutants. Based on their chemical structure, PCBs are classified into non-ortho-substituted and ortho-substituted congeners. Ortho-substituted PCBs are structurally similar to dioxin and their toxic effects and mode of action are well established. In contrast, very little is known about the effects of non-ortho-substituted PCBs, particularly during early development. The objective of this study is to investigate the effects of exposure to an environmentally prominent ortho-substituted...

Tracking wildlife energy dynamics with unoccupied aircraft systems and 3-dimensional photogrammetry

Michelle Shero, Julian Dale, Alexander Seymour, Mike Hammill, Arnaud Mosnier, Samuel Mongrain & David Johnston
We present a novel application using unoccupied aircraft systems (UAS; drones) for structure-from-motion three-dimensional (3-D) photogrammetry of multiple, free-ranging animals simultaneously. Pinnipeds reliably haul-out on shore for pupping and breeding each year, accompanied by dramatic female-to-pup mass transfer over a short lactation period and males lose mass while defending mating territories. This provides a tractable study system for validating the use of UAS as a non-invasive tool for tracking energy dynamics in wild populations. UAS...

Exposure to 3, 3’, 4, 4’, 5-pentachlorobiphenyl (PCB 126) causes widespread DNA hypomethylation in adult zebrafish testis

Neelakanteswar Aluru & Jan Engelhardt
Exposure to environmental toxicants during preconception have been shown to affect offspring health and epigenetic mechanisms such as DNA methylation are hypothesized to be involved in adverse outcomes. However, studies addressing the effects of exposure to environmental toxicants during preconception on epigenetic changes in gametes are limited. The objective of this study is to determine the effect of preconceptional exposure to a dioxin-like PCB (PCB126) on DNA methylation and gene expression in testis. Adult zebrafish...

Geochemical Data for the Olla and Nebo-Hemphill Oil Fields, Louisiana

Rebecca L Tyne, Peter H Barry, Michael Lawson, Hao Xie, Darren J Hillegonds, John M Eiler & Chris J Ballentine
Formation water geochemistry and gas geochemistry from 6 wells in the Olla Oil Field and 7 wells in the Nebo-Hemphill Oil Field Louisiana (Longitude range: -92.2297 to -92.1487, Latitude range: 31.83128 to 31.56586.), sampled in 2015. Formation water geochemistry for cation and anions and in mmol/l and ppm, these were measured at an internal ExxonMobil facility. Casing gases were used to make the remaining measurements. Stable noble gas isotopes (He, Ne, Ar, Kr, Xe) were...

Hollow Core Fiber Methane Sensor

Anna Michel & Jason Kapit
We have developed a hollow core fiber optic sensor capable of measuring dissolved methane gas in liquids using only nanoliters of sample gas. The sensor is based on an anti-resonant hollow core fiber combined with a permeable capillary membrane inlet which extracts gas from the liquid for analysis.

Pathways to the Denmark Strait Overflow: A Lagrangian Study in the Iceland Sea

Marieke Femke de Jong, Amy Bower, Henrik Søiland, Heather Furey & Andree L. Ramsey
The goal of this project was to directly measure the dense water pathways upstream of the Denmark Strait in the Iceland Sea and compare the results to existing ideas about the dynamics of the circulation by deploying 45 acoustically tracked RAFOS floats over a two year time period (24-Jul-2013 to 29-May-2015). The floats were ballasted to drift at a target depth of 500m, recording pressure, temperature, and Times Of Arrivals (TOAs) every six hours or...

Supplementary Information: Antibiotic resistance in Vibrio-like bacteria is common on Cape Cod, MA beaches

Megan May & Rebecca J. Gast
Antibiotic resistance (AR) is a natural process, enhanced by anthropogenic antibiotic use. Natural environments, like the ocean, act as reservoirs of resistance; but until recently, little research has examined their dynamics. Six beaches on Cape Cod, MA, with varying human impacts, were sampled over one year on nine occasions. Vibrio-like bacteria were isolated from wet sand, dry sand, and water from each beach and tested for sensitivity to five antibiotics (amoxicillin/clavulanic acid, ciprofloxacin, doxycycline, oxytetracycline,...

Data from: Trophic plasticity in a common reef-building coral: Insights from δ13C analysis of essential amino acids

Michael Fox, Emma Elliott Smith, Jennifer Smith & Seth Newsome
1. Reef-building corals are mixotrophic organisms that can obtain nutrition from endosymbiotic microalgae (autotrophy) and particle capture (heterotrophy). Heterotrophic nutrition is highly beneficial to many corals, particularly in times of stress. Yet the extent to which different coral species rely on heterotrophic nutrition remains largely unknown because it is challenging to quantify. 2. We developed a quantitative approach to investigate coral nutrition using carbon isotope (δ13C) analysis of six essential amino acids (AAESS) in a...

Data from: Fate of internal waves on a shallow shelf

Kristen Davis, Robert Arthur, Emma Reid, Thomas DeCarlo, Anne Cohen, Oliver Fringer & Justin Rogers
Internal waves strongly influence the physical and chemical environment of coastal ecosystems worldwide. We report novel observations from a distributed temperature sensing (DTS) system that tracked the transformation of internal waves from the shelf break to the surf zone over a narrow shelf-slope region in the South China Sea. The spatially-continuous view of temperature fields provides a perspective of physical processes commonly available only in laboratory settings or numerical models, including internal wave reflection off...

Genetic diversity and connectivity of southern right whales (Eubalaena australis) found in the Brazil and Chile–Peru wintering grounds and the South Georgia (Islas Georgias del Sur) feeding ground

Emma L Carroll, Paulo Ott, Louise McMillan, Bárbara Galletti Vernazzani, Petra Neveceralova, Els Vermeulen, Oscar Gaggiotti, Artur Andriolo, C. Scott Baker, Connor Bamford, Peter Best, Elsa Cabrera, Susannah Calderan, Andrea Chirife, Rachel M. Fewster, Paulo A. C. Flores, Timothy Frasier, Thales R. O. Freitas, Karina Groch, Pavel Hulva, Amy Kennedy, Russell Leaper, Mathew S. Leslie, Michael Moore, Larissa Oliviera … & Jennifer A Jackson
As species recover from exploitation, continued assessments of connectivity and population structure are warranted to provide information for conservation and management. This is particularly true in species with high dispersal capacity, such as migratory whales, where patterns of connectivity could change rapidly. Here we build on a previous long-term, large-scale collaboration on southern right whales (Eubalaena australis) to combine new (nnew) and published (npub) mitochondrial (mtDNA) and microsatellite genetic data from all major wintering grounds...
