Marine soundscape variation reveals insights into baleen whales and their environment: a case study in central New Zealand

Victoria Warren, Craig McPherson, Giacomo Giorli, Kimberly Goetz & Craig Radford
Baleen whales reliably produce stereotyped vocalizations, enabling their spatio-temporal distributions to be inferred from acoustic detections. Soundscape analysis provides an integrated approach whereby vocal species, such as baleen whales, are sampled holistically with other acoustic contributors to their environment. Acoustic elements that occur concurrently in space, time and/or frequency can indicate overlaps between free-ranging species and potential stressors. Such information can inform risk assessment framework models. Here, we demonstrate the utility of soundscape monitoring in...

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...

Coldwater fish in a warm water world: implications for predation of salmon smolts during estuary transit

Matthew Nobriga, Cyril Michel, Rachel Johnson & J.D. Wikert
Predator-prey systems face intensifying pressure from human exploitation and a warming climate with implications for where and how natural resource management can successfully intervene. We hypothesized young salmon migrating to the Pacific Ocean face a seasonally intensifying predator gauntlet when warming water temperature intensifies a multiple predator effect (MPE) from Striped Bass Morone saxatilis, and Largemouth Bass Micropterus salmoides. We evaluated this hypothesis using data synthesis and simulation modeling. 2. Contemporary studies based on acoustically-tagged...

Sebastes genomic islands of divergence

Kristen Behrens, Quinn Girasek, Alex Sickler, John Hyde & Vincent Buonaccorsi
Depth separation is a proposed driver of speciation in marine fishes, with marine rockfish (genus Sebastes) providing a potentially informative study system. Sebastes rockfishes are commercially and ecologically important. This genus encompasses more than one hundred species and the ecological and morphological variance between these species provides opportunity for identifying speciation-driving adaptations, particularly along a depth gradient. A reduced-representation sequencing method (ddRADseq) was used to compare 95 individuals encompassing six Sebastes species. In this study,...

CNS isotope values in eye lenses for juvenile and adult Chinook Salmon

Miranda Bell Tilcock, Carson Jeffres, Andrew Rypel, Ted Sommer, Jacob Katz, George Whitman & Rachel Johnson
Tracking habitat use and dietary shifts in migratory species is vital to conservation and management. Yet conventional animal tracking often precludes tracking small juveniles at critical life-stages where recruitment bottlenecks often manifest. Stable isotope analysis (SIA) in consecutive laminae in eye lenses, a protein-rich depositional tissue, has emerged as a promising tool in fishes to develop long-term interpretive records of dietary histories using a single archival tissue. Currently, studies using fisheye lenses to study SIA...

Ocean acidification alters properties of the exoskeleton in adult tanner crabs, Chionoecetes bairdi

Gary Dickinson, Shai Bejerano, Trina Salvador, Christine Makdisi, Shrey Patel, W. Christopher Long, Katherine Swiney, Robert Foy, Brittan Steffel, Kathryn Smith & Richard Aronson
Ocean acidification can affect the ability of calcifying organisms to build and maintain mineralized tissue. In decapod crustaceans, the exoskeleton is a multilayered structure composed of chitin, protein, and mineral, predominately magnesian calcite or amorphous calcium carbonate (ACC). We investigated the effects of acidification on the exoskeleton of mature (post-terminal-molt) female southern Tanner crabs, Chionoecetes bairdi. Crabs were exposed to one of three pH levels—8.1, 7.8, or 7.5—for two years. Reduced pH led to a...

Gene flow influences the genomic architecture of local adaptation in six riverine fish species

Yue Shi, Kristen Bouska, Garrett Mckinney, William Dokai, Andrew Bartels, Megan McPhee & Wes Larson
Understanding how gene flow influences adaptive divergence is important for predicting adaptive responses. Theoretical studies suggest that when gene flow is high, clustering of adaptive genes in fewer genomic regions would protect adaptive alleles from recombination and thus be selected for, but few studies have tested it with empirical data. Here, we used RADseq to generate genomic data for six fish species with contrasting life histories from six reaches of the Upper Mississippi River System,...
