Data from: Temporal variation in the vocal behaviour of southern right whales in the Auckland Islands, New ZealandTrudi Webster, Sofie Van Parijs, Will Rayment & Steve Dawson
Autonomous recorders are frequently utilised for examining vocal behaviour of animals, and are particularly effective in remote habitats. Southern right whales are known to have an extensive acoustic repertoire. A recorder was moored at the isolated sub-Antarctic Auckland Islands for a year to examine whether the acoustic behaviour of southern right whales differed seasonally and throughout the day at their main calving ground in New Zealand. Recordings were made in each month except June, and...

Earth’s deep oceans remains less well understood than the surface of Mars. Beaked whales (ziphiids) are among the most visible inhabitants of the abyss, due to their large size and worldwide distribution, yet their diversity and ecology remain obscure. We combine genomic and morphometric analyses to reveal a new Southern Hemisphere ziphiid species, Ramari’s beaked whale, Mesoplodon eueu, whose name is linked to the Indigenous people of the lands from which the species holotype and...

Population increases over the past several decades provide natural settings in which to study the evolutionary processes that occur during bottleneck, growth, and spatial expansion. We used parallel natural experiments of historical decline and subsequent recovery in two sympatric pinniped species in the Northwest Atlantic, the gray seal (Halichoerus grypus atlantica) and harbor seal (Phoca vitulina vitulina), to study the impact of recent demographic change in genomic diversity. Using restriction site‐associated DNA sequencing, we assessed...
A real-time PCR assay to detect predation by spiny dogfish on Atlantic cod in the western North Atlantic Ocean.Steven Pitchford, Brian E. Smith & Richard McBride
Conventional observations show spiny dogfish (Squalus acanthius Linnaeus) rarely eat Atlantic cod (Gadus morhua Linnaeus; 0.02% of stomachs) in the northwestern Atlantic Ocean. Critics express concern that digestion may limit species-level prey identification, and with recovery from overfishing, dogfish populations may be suppressing cod by competition or predation. This study applied a real-time PCR TaqMan assay to identify cod in dogfish stomachs collected by cooperating fishing boats during normal trawling operations (May 2014 – May...
Data from: Separation of realized ecological niche axes among sympatric tilefishes provides insight into potential drivers of co‐occurrence in the NW AtlanticJill A. Olin, Oliver Shipley, Robert Cerrato, Paul Nitschke, Cedric Magen & Michael Frisk
Golden and Blueline Tilefish (Lopholatilus chamaeleonticeps and Caulolatilus microps) are keystone taxa in northwest (NW) Atlantic continental shelf‐edge environments due to their biotic (trophic‐mediated) and abiotic (ecosystem engineering) functional roles combined with high‐value fisheries. Despite this importance, the ecological niche dynamics (i.e., those relating to trophic behavior and food‐web interactions) of these sympatric species are poorly understood, knowledge of which may be consequential for maintaining both ecosystem function and fishery sustainability. We used stable isotope...
