Data from: Increased dietary intake of saturated fatty acid heptadecanoic acid (C17:0) associated with decreasing ferritin and alleviated metabolic syndrome in dolphins

Stephanie K. Venn-Watson, Celeste Parry, Mark Baird, Sacha Stevenson, Kevin Carlin, Risa Daniels, Cynthia R. Smith, Richard Jones, Randall S. Wells, Sam Ridgway & Eric D. Jensen
Similar to humans, bottlenose dolphins (Tursiops truncatus) can develop metabolic syndrome and associated high ferritin. While fish and fish-based fatty acids may protect against metabolic syndrome in humans, findings have been inconsistent. To assess potential protective factors against metabolic syndrome related to fish diets, fatty acids were compared between two dolphin populations with higher (n = 30, Group A) and lower (n = 19, Group B) mean insulin (11 ± 12 and 2 ± 5...

Area and Timing data and R script for: 3D scanning as a tool to measure growth rates of live coral microfragments used for coral reef restoration

Hanna Koch, Bailey Wallace, Allyson DeMerlis, Abigail Clark & Robert Nowicki
Rapid and widespread declines in coral health and abundance have driven increased investments in coral reef restoration interventions to jumpstart population recovery. Microfragmentation, an asexual propagation technique, is used to produce large numbers of corals for research and restoration. As part of resilience-based restoration, coral microfragments of different genotypes and species are exposed to various stressors to identify candidates for propagation. Growth rate is one of several important fitness-related traits commonly used in candidate selection,...

Archive data for: Loss of predation risk from apex predators can exacerbate marine tropicalization caused by extreme climatic events

Robert Nowicki, Jordan Thomson, James Fourqurean, Aaron Wirsing & Michael Heithaus
1. Extreme climatic events (ECEs) and predator removal represent some of the most widespread stressors to ecosystems. Though species interactions can alter ecological effects of climate change (and vice versa), it is less understood whether, when, and how predator removal can interact with ECEs to exacerbate their effects. Understanding the circumstances under which such interactions might occur is critical because predator loss is widespread and ECEs can generate rapid phase shifts in ecosystems which can...

Data from: Heritable variation and lack of tradeoffs suggest adaptive capacity in Acropora cervicornis despite negative synergism under climate change scenarios

Erinn Muller, Ashley Dungan, Wyatt Million, Katherine Eaton, Chelsea Petrik, Erich Bartels, Emily Hall & Carly Kenkel
Knowledge of multi-stressor interactions and the potential for trade-offs among tolerance traits is essential for developing intervention strategies for the conservation and restoration of reef ecosystems in a changing climate. Thermal extremes and acidification are two major co-occurring stresses predicted to limit the recovery of vital Caribbean reef-building corals. Here we conducted an aquaria-based experiment to quantify the effects of increased water temperatures and pCO2 individually and in concert on 12 genotypes of the endangered...

Data from: Indirect legacy effects of an extreme climactic event on a marine megafaunal community

Robert Nowicki, Michael Heithaus, Jordan Thomson, Derek Burkholder, Kirk Gastrich & Aaron Wirsing
While extreme climactic events (ECEs) are predicted to become more frequent, reliably predicting their impacts on consumers remains challenging– particularly for large consumers in marine environments. Many studies that do evaluate ECE effects focus primarily on direct effects, though indirect effects can be equally or more important. Here, we investigate the indirect impacts of the 2011 “Ningaloo Niño” marine heatwave ECE on a diverse megafauna community in Shark Bay, Western Australia. We use an 18...

Data from: A low-cost solution for documenting distribution and abundance of endangered marine fauna and impacts from fisheries

Nicolas J. Pilcher, Kanjana Adulyanukosol, Himansu Das, Patricia Davis, Ellen Hines, Donna Kwan, Helene Marsh, Louisa Ponnampalam & John Reynolds
Fisheries bycatch is a widespread and serious issue that leads to declines of many important and threatened marine species. However, documenting the distribution, abundance, population trends and threats to sparse populations of marine species is often beyond the capacity of developing countries because such work is complex, time consuming and often extremely expensive. We have developed a flexible tool to document spatial distribution and population trends for dugongs and other marine species in the form...

The Global FinPrint Project

Colin Simpfendorfer, Demian Chapman & Michelle Heupel
The Global Finprint project is a global scale survey of sharks and rays on coral reefs. It uses baited remote underwater video systems (BRUVS) to collect data. The data stored are all video files from the individual drops. This dataset represents the sampling in the Coral Triangle and Pacific regions of the project.

Data from: Evidence for a host role in thermotolerance divergence between populations of the mustard hill coral (Porites astreoides) from different reef environments

Carly D. Kenkel, Gretchen Goodbody-Gringley, Damien Caillaud, Sarah W. Davies, Erich Bartels & Mikhail V. Matz
Studying the mechanisms that enable coral populations to inhabit spatially varying thermal environments can help evaluate how they will respond in time to the effects of global climate change and elucidate the evolutionary forces that enable or constrain adaptation. Inshore reefs in the Florida Keys experience higher temperatures than offshore reefs for prolonged periods during the summer. We conducted a common garden experiment with heat stress as our selective agent to test for local thermal...

Data from: Genome-wide investigation of adaptation to harmful algal blooms in common bottlenose dolphins (Tursiops truncatus)

Kristina M. Cammen, Thomas F. Schultz, Patricia E. Rosel, Randall S. Wells & Andrew J. Read
Harmful algal blooms (HABs), which can be lethal in marine species and cause illness in humans, are increasing worldwide. In the Gulf of Mexico, HABs of Karenia brevis produce neurotoxic brevetoxins that cause large-scale marine mortality events. The long history of such blooms, combined with the potentially severe effects of exposure, may have produced a strong selective pressure for evolved resistance. Advances in next-generation sequencing, in particular genotyping-by-sequencing, greatly enable the genomic study of such...
