Larvae of deep-sea invertebrates harbor low-diversity bacterial communities

Tyler Carrier, Stace Beaulieu, Susan Mills, Lauren Mullineaux & Adam Reitzel
Microbial symbionts are a common life-history character of marine invertebrates and their developmental stages. Communities of bacteria that associate with the eggs, embryos, and larvae of coastal marine invertebrates are species-specific and correlate with aspects of host biology and ecology. The richness of bacteria associated with the developmental stages of coastal marine invertebrates spans four orders of magnitude from single mutualists to 1,000s of unique taxa. If the developmental stages of coastal species are broadly...

Genotypes of 6 InDel markers for species identification from the Calanus culture at the EMBRC-ERIC laboratory for low-level trophic interactions, NTNU SeaLab

Elise Skottene, Ann M. Tarrant, Dag Altin, Rolf Erik Olsen, Marvin Choquet & Kristina Ø. Kvile
Late developmental stages of marine copepods in the genus Calanus can spend extended periods in a dormant stage (diapause). During the growth season, copepods must accumulate sufficient lipid stores to survive diapause. Predation risk is often overlooked as a potential diapause-inducing cue. We tested experimentally if predation risk in combination with high or low food availability leads to differences in lipid metabolism, and potentially diapause initiation. Expression of lipid metabolism genes showed that food availability...

Landfast ice: a major driver of reproductive success in a polar seabird

Sara Labrousse, Alexander D. Fraser, Michael Sumner, Frédéric Le Manach, Christophe Sauser, Isabella Horstmann, Eileen Devane, Karine Delord, Stéphanie Jenouvrier & Christophe Barbraud
In a fast-changing world, polar ecosystems are threatened by climate variability. Understanding the roles of fine-scale processes, and linear and nonlinear effects of climate factors on the demography of polar species is crucial for anticipating the future state of these fragile ecosystems. While the effects of sea ice on polar marine top predators are increasingly being studied, little is known about the impacts of landfast ice (LFI) on this species community. Based on a unique...

Local vs. site-level effects of algae on coral microbial communities

Amy Briggs, Anya Brown & Craig Osenberg
Microbes influence ecological processes, including the dynamics and health of macro-organisms and their interactions with other species. In coral reefs, microbes mediate negative effects of algae on corals when corals are in contact with algae. However, it is unknown whether these effects extend to larger spatial scales, such as at sites with high algal densities. We investigated how local algal contact and site-level macroalgal cover influenced coral microbial communities in a field study at two...

PCB126 exposure revealed alterations in m6A RNA modifications in transcripts associated with AHR activation

Neelakanteswar Aluru & Sibel Karchner
Chemical modifications of proteins, DNA and RNA moieties play critical roles in regulating gene expression. Emerging evidence suggests the RNA modifications (epitranscriptomics) have substantive roles in basic biological processes. One of the most common modifications in mRNA and noncoding RNAs is N6-methyladenosine (m6A). In a subset of mRNAs, m6A sites are preferentially enriched near stop codons, in 3′ UTRs, and within exons, suggesting an important role in the regulation of mRNA processing and function including...

Andreanoff Active-Source OBS Experiment

This is an active-source experiment support by OBSIC. Short-period OBS will be deployed along one strike-line just north of the Aleutians, and two dip lines that cross the Aleutian Arc. The shooting ship will be the R/V Marcus Langseth. The majority of OBS will be equipped with a 3-component geophone (4.5 Hz resonant frequency) and a hydrophone. Some stations deployed in the Aleutians Trench where water depths exceed ~5000 m will be moored above the...

Seasonal trends and diel patterns of downsweep and SEP calls in Chilean blue whales (Balaenoptera musculus)

Laura Redaelli, Sari Mangia Woods, Rafaela Landea Briones & Laela S. Sayigh
To learn more about occurrence and behavior of a recently discovered population of blue whales, passive acoustic data were collected for 15 consecutive months (January 2012 – April 2013) in the Chiloense ecoregion of southern Chile. Automatic detectors and manual auditing were used to detect blue whale songs (SEP calls) and D calls, which were then analyzed to gain insights into temporal calling patterns. We found a year-round acoustic presence of D calls, with the...

Data from: Population growth in a wild bird is buffered against phenological mismatch

Thomas E. Reed, Vidar Grotan, Stephanie Jenouvrier, Bernt-Erik Saether & Marcel E. Visser
Broad-scale environmental changes are altering patterns of natural selection in the wild, but few empirical studies have quantified the demographic cost of sustained directional selection in response to these changes. We tested whether population growth in a wild bird is negatively affected by climate change–induced phenological mismatch, using almost four decades of individual-level life-history data from a great tit population. In this population, warmer springs have generated a mismatch between the annual breeding time and...

Data from: Late spring nitrate distributions beneath the ice-covered northeastern Chukchi Shelf

Kevin R. Arrigo, Matthew M. Mills, Gert L. Van Dijken, Kate E. Lowry, Robert S. Pickart & Reiner Schlitzer
Measurements of late springtime nutrient concentrations in Arctic waters are relatively rare due to the extensive sea ice cover that makes sampling difficult. During the SUBICE cruise in May-June 2014, an extensive survey of hydrography and pre-bloom concentrations of inorganic macronutrients, oxygen, particulate organic carbon and nitrogen, and chlorophyll a was conducted in the northeastern Chukchi Sea. Cold (< -1.5°C) winter water was prevalent throughout the study area, and the water column was weakly stratified....

Data from: Density dependence in demography and dispersal generates fluctuating invasion speeds

Lauren L. Sullivan, Bingtuan Li, Tom E. X. Miller, Michael G. Neubert & Allison K. Shaw
Density dependence plays an important role in population regulation and is known to generate temporal fluctuations in population density. However, the ways in which density dependence affects spatial population processes, such as species invasions, are less understood. Although classical ecological theory suggests that invasions should advance at a constant speed, empirical work is illuminating the highly variable nature of biological invasions, which often exhibit nonconstant spreading speeds, even in simple, controlled settings. Here, we explore...

Data from: Environmental gradients predict the genetic population structure of a coral reef fish in the Red Sea

Gerrit B. Nanninga, Pablo Saenz-Agudelo, Manica Andrea, Michael L. Berumen & Andrea Manica
The relatively recent fields of terrestrial landscape and marine seascape genetics seek to identify the influence of biophysical habitat features on the spatial genetic structure of populations or individuals. Over the last few years, there has been accumulating evidence for the effect of environmental heterogeneity on patterns of gene flow and connectivity in marine systems. Here we investigate the population genetic patterns of an anemonefish, Amphiprion bicinctus, along the Saudi Arabian coast of the Red...

Data from: From the track to the ocean: using flow control to improve marine bio-logging tags for cetaceans

Giovani Fiore, Erik Anderson, C. Spencer Garborg, Mark Murray, Mark Johnson, Michael J. Moore, Laurens Howle & K. Alex Shorter
Bio-logging tags are an important tool for the study of cetaceans, but superficial tags inevitably increase hydrodynamic loading. Substantial forces can be generated by tags on fast-swimming animals, potentially affecting behavior and energetics or promoting early tag removal. Streamlined forms have been used to reduce loading, but these designs can accelerate flow over the top of the tag. This non-axisymmetric flow results in large lift forces (normal to the animal) that become the dominant force...

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,...

Southern Cape Cod Bay hypoxia data

Malcolm E. Scully, Tracy L. Pugh, W. Rockwell Geyer, Amy Costa & Owen C. Nichols
This project investigated the distribution of low dissolved oxygen bottom waters (hypoxia) in southern Cape Cod Bay. Hypoxia was documented for the first time in late summer 2019 and 2020 despite extensive monitoring for the past decade. The data include: 1) measurements of bottom dissolved oxygen collected in 2019 by the Massachusetts Division of Marine Fisheries (MDMF) and the Center for Coastal Studies (CCS) ; 2) full water column profiles of temperature, salinity, chlorophyll fluorescence,...

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...

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...

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...

Improved biodiversity detection using a large-volume environmental DNA sampler with in situ filtration and implications for marine eDNA sampling strategies

Annette Govindarajan, Luke McCartin, Allan Adams, Elizabeth Allan, Abhimanyu Belani, Rene Francolini, Justin Fujii, Daniel Gomez-Ibanez, Amy Kukulya, Frederick Marin, Kaitlyn Tradd, Dana Yoerger, Jill McDermott & Santiago Herrera
Metabarcoding analysis of environmental DNA samples is a promising new tool for marine biodiversity and conservation. Typically, seawater samples are obtained using Niskin bottles and filtered to collect eDNA. However, standard sample volumes are small relative to the scale of the environment, conventional collection strategies are limited, and the filtration process is time consuming. To overcome these limitations, we developed a new large – volume eDNA sampler with in situ filtration, capable of taking up...

Transcriptome data: salinity adaptation in Rhithropanopeus harrisii across an estuarine gradient

Carolyn Tepolt, April Blakeslee & Amy Fowler
Rhithropanopeus harrisii is a common estuarine crab native to the East and Gulf Coasts of North America. Here, it is found along a broad range of salinities, spanning from ~1 PSU to ~25 PSU along estuarine gradients. As part of a larger study on the species' potential use of low-salinity refuges from parasitism, we tested for differences in gene expression with salinity using crabs from three distinct estuarine reaches along the Pamlico River in North...
