Data from: Scale‐dependent spatial patterns in benthic communities around a tropical island seascape

Eoghan A. Aston, Gareth J. Williams, J. A. Mattias Green, Andrew J. Davies, Lisa M. Wedding, Jamison M. Gove, Jean-Baptiste Jouffray, Timothy T. Jones & Jeanette Clark
Understanding and predicting patterns of spatial organization across ecological communities is central to the field of landscape ecology, and a similar line of inquiry has begun to evolve sub‐tidally among seascape ecologists. Much of our current understanding of the processes driving marine community patterns, particularly in the tropics, has come from small‐scale, spatially‐discrete data that are often not representative of the broader seascape. Here we expand the spatial extent of seascape ecology studies and combine...

Data from: First satellite tracks of South Atlantic sea turtle ‘lost years’: seasonal variation in trans-equatorial movement

Katherine L. Mansfield, Milagros L. Mendilaharsu, Nathan F. Putman, Maria A. G. Dei Marcovaldi, Alexander E. Sacco, Gustave Lopez, Thais Pires & Yonat Swimmer
In the South Atlantic Ocean, few data exist regarding the dispersal of young oceanic sea turtles. We characterized the movements of laboratory-reared yearling loggerhead turtles from Brazilian rookeries using novel telemetry techniques, testing for differences in dispersal during different periods of the sea turtle hatching season that correspond to seasonal changes in ocean currents. Oceanographic drifters deployed alongside satellite-tagged turtles allowed us to explore the mechanisms of dispersal (passive drift or active swimming). Early in...

Data from: Calculating the ecological impacts of animal-borne instruments on aquatic organisms

T. Todd Jones, Kyle S. Van Houtan, Brian L. Bostrom, Peter Ostafichuk, Jon Mikkelsen, Emre Tezcan, Michael Carey, Brittany Imlach & Jeffrey A. Seminoff
1. Animal-borne instruments provide researchers with valuable data to address important questions on wildlife ecology and conservation. However, these devices have known impacts on animal behaviour and energetics. Tags deployed on migrating animals may reduce reproductive output through increased energy demands or cause phenological mismatches of foraging and nesting events. For marine organisms, the only tagging guidelines that exist are based on lift and thrust impacts on birds – concepts that do not translate well...

Co-occurrence of beaked whale strandings and naval sonar in the Mariana Islands, Western Pacific

Anne Simonis, Robert Brownell, Bruce Thayre, Jennifer Trickey, Erin Oleson, Roderick Huntington & Simone Baumann-Pickering
Mid-frequency active sonar (MFAS), used for antisubmarine warfare (ASW), has been associated with multiple beaked whale (BW) mass stranding events. Multinational naval ASW exercises have utilized MFAS offshore of the Mariana Archipelago semi-annually since 2006. We report BW and MFAS acoustic activity near the islands of Saipan and Tinian from March 2010 through November 2014. Signals from Cuvier’s (Ziphius cavirostris) and Blainville’s beaked whales (Mesoplodon densirostris), and a third unidentified BW species were detected throughout...

Data from: The importance of standardization for biodiversity comparisons: a case study using Autonomous Reef Monitoring Structures (ARMS) and metabarcoding to measure cryptic diversity on Mo'orea coral reefs, French Polynesia

Emma Ransome, Jonathan B. Geller, Molly Timmers, Matthieu Leray, Angka Mahardini, Andrianus Sembiring, Allen G. Collins & Christopher P. Meyer
The advancement of metabarcoding techniques, declining costs of high-throughput sequencing and development of systematic sampling devices, such as autonomous reef monitoring structures (ARMS), have provided the means to gather a vast amount of diversity data from cryptic marine communities. However, such increased capability could also lead to analytical challenges if the methods used to examine these communities across local and global scales are not standardized. Here we compare and assess the underlying biases of four...

Data from: Evaluating management strategies to optimise coral reef ecosystem services

Mariska Weijerman, Jamison M. Gove, Ivor D. Williams, William J. Walsh, Dwayne Minton & Jeffrey J. Polovina
Earlier declines in marine resources, combined with current fishing pressures and devastating coral mortality in 2015, have resulted in a degraded coral reef ecosystem state at Puakō in West Hawaiʹi. Changes to resource management are needed to facilitate recovery of ecosystem functions and services. We developed a customised ecosystem model to evaluate the performance of alternative management scenarios at Puakō in the provisioning of ecosystem services to human users (marine tourists, recreational fishers) and enhancing...

Hide ‘n seq: direct versus indirect metabarcoding of coral reef cryptic communities

Patrick Nichols, Molly Timmers & Peter Marko
Ecological patterns in biodiversity are primarily based on conspicuous organisms. Few methods are used to survey the taxonomically rich cryptobiome, which is made up of inhabitants from within microhabitats. One way that cryptic marine biodiversity can be non-invasively surveyed is by analyzing environmental DNA (eDNA) present in seawater. Using coral reefs as a model system, here we compare estimates of cryptic diversity among community biomass and eDNA metabarcoding sampling methods with a broad eukaryotic marker...

Data from: Limited trophic partitioning among sympatric delphinids off a tropical oceanic atoll

Hillary Young, Katherine Nigro, Douglas J. McCauley, Lisa T. Ballance, Erin M. Oleson & Simone Baumann-Pickering
Understanding trophic relationships among marine predators in remote environments is challenging, but it is critical to understand community structure and dynamics. In this study, we used stable isotope analysis of skin biopsies to compare the isotopic, and thus, trophic niches of three sympatric delphinids in the waters surrounding Palmyra Atoll, in the Central Tropical Pacific: the melon-headed whale (Peponocephala electra), Gray’s spinner dolphin (Stenella longirostris longirostris), and the common bottlenose dolphin (Tursiops truncatus). δ15N values...

Data from: Integrating multiple technologies to understand the foraging behaviour of Hawaiian monk seals

Kenady Wilson, Charles Littnan, Pat Halpin, Andrew Read & Patrick Halpin
The objective of this research was to investigate and describe the foraging behaviour of monk seals in the main Hawaiian Islands. Specifically, our goal was to identify a metric to classify foraging behaviour from telemetry instruments. We deployed accelerometers, seal-mounted cameras and GPS tags on six monk seals during 2012–2014 on the islands of Molokai, Kauai and Oahu. We used pitch, calculated from the accelerometer, to identify search events and thus classify foraging dives. A...

Data from: Nuclear and mitochondrial patterns of population structure in North Pacific false killer whales (Pseudorca crassidens)

Karen K. Martien, Susan J. Chivers, Robin W. Baird, Frederick I. Archer, Antoinette M. Gorgone, Brittany L. Hancock-Hanser, David Mattila, Daniel J. McSweeney, Erin M. Oleson, Carol Palmer, Victoria L. Pease, Kelly M. Robertson, Gregory S. Schorr, Mark B. Schultz, Daniel L. Webster & Barbara L. Taylor
False killer whales (Pseudorca crassidens) are large Delphinids typically found in deep water far offshore. However, in the Hawaiian Archipelago there are two resident island-associated populations of false killer whales, one in the waters around the main Hawaiian Islands (MHI) and one in the waters around the Northwestern Hawaiian Islands (NWHI). We use mitochondrial DNA (mtDNA) control region sequences and genotypes from 16 nuclear (nucDNA) microsatellite loci from 206 individuals to examine levels of differentiation...

Data from: Familial social structure and socially-driven genetic differentiation in Hawaiian short-finned pilot whales

Amy M. Van Cise, Karen. K. Martien, Sabre D. Mahaffy, Robin W. Baird, Daniel L. Webster, James H. Fowler, Erin M. Oleson & Phillip A. Morin
Social structure can have a significant impact on divergence and evolution within species, especially in the marine environment, which has few environmental boundaries to dispersal. On the other hand, genetic structure can affect social structure in many species, through an individual preference toward associating with relatives. One social species, the short-finned pilot whale (Globicephala macrorhynchus), has been shown to live in stable social groups for periods of at least a decade. Using mitochondrial control sequences...
