Fitting fangs in a finite face: A novel fang accommodation strategy in a 280-million-year-old ray-finned fish. [PDF]

J Anat, 2023
Left jaws of †Brazilichthys macrognathus (DGM 1061‐P) in mesial view. Palatoquadrate sectioned to expose the fenestration of the maxilla and the fangs of the lower jaw (in red). Scale bar = 10 mm. Abstract Though Paleozoic ray‐finned fishes are considered to be morphologically conservative, we report a novel mode of fang accommodation (i.e., the ...

Marine water environmental DNA metabarcoding provides a comprehensive fish diversity assessment and reveals spatial patterns in a large oceanic area. [PDF]

Ecol Evol, 2020
eDNA samples provide information on fish diversity in a broad‐scale marine area, detecting almost ten times more fish species compared with pelagic trawling, including some considered elusive or difficult to capture with traditional fishing methods.

Design and Validation of an Open-Close Device for Integrated Environmental DNA Sampling Detects A Depth Gradient in Indian Ocean Deep-Sea Fish Assemblages. [PDF]

Ecol Evol
The goal of this study was to leverage existing survey technology to design and test an eDNA sampler that captures an integrated eDNA sample over the length of a deep‐water transect. We provide a biological interpretation of the resulting data, demonstrating the usefulness of such technology to understand the ocean environments, using fish species as ...

Estimating trends and magnitudes of bycatch in the tuna fisheries of the Western and Central Pacific Ocean

Fish and Fisheries, Volume 24, Issue 5, Page 812-828, September 2023., 2023
Abstract Minimising the unintended capture of fish, marine mammals, reptiles, seabirds and other marine organisms is an important component of responsible fisheries management and for stabilising declines and rebuilding populations of threatened species.

Early prey intake of a short-finned pilot whale (Globicephala macrorhynchus Gray, 1846, Cetacea: Delphinidae) in the Canary Islands. [PDF]

Ecol Evol
The short‐finned pilot whale, Globicephala macrorhynchus in the Canary Islands. Stomach contents, trophic markers, skin isotopic ratios of nitrogen (δ15N: 15N/14N) and carbon (δ13C: 13C/12C), and fatty acid profiles of the blubber of a short‐finned pilot whale were analyzed to obtain the insights in their early hunting behavior.

MetaBARFcoding: DNA‐barcoding of regurgitated prey yields insights into Christmas shearwater (Puffinus nativitatis) foraging ecology at Hōlanikū (Kure Atoll), Hawaiʻi

Environmental DNA, Volume 4, Issue 1, Page 254-268, January 2022., 2022
DNA “metaBARFcoding” was used in conjunction with DNA barcoding to augment morphological identification of prey in highly digested regurgitations from Christmas shearwaters Puffinus nativitatis at Hōlanikū, Hawaiʻi. The metabarcoding technique identified 87 unique taxa from 29 families of fish and squid, spanning diverse taxa, including families of ...

Sifting environmental DNA metabarcoding data sets for rapid reconstruction of marine food webs

Fish and Fisheries, Volume 22, Issue 4, Page 822-833, July 2021., 2021
Abstract Marine ecosystems are changing rapidly due to ocean warming, overfishing and a raft of other anthropogenic impacts. Such changes are expected to disrupt productivity dynamics and alter marine food webs, with likely negative consequences for ecosystem services.

Deep-pelagic fishes: Demographic instability in a stable environment. [PDF]

Ecol Evol
In this study, we tested the hypothesis that a stable environment should lead to stable demographic histories for the species occupying that environment. We used molecular data to investigate the demographic histories of 11 species of fishes residing in the deep‐pelagic, one of the most stable environments on the planet.

New Mediterranean biodiversity records (March 2016) [PDF]

, 2016
In this Collective Article on “New Mediterranean Biodiversity Records”, we present additional records of species found in the Mediterranean Sea. These records refer to eight different countries mainly throughout the northern part of the basin, and ...

Fatal predation of oilfish, Ruvettus pretiosus (Gempylidae), by a young short-finned pilot whale, Globicephala macrorhynchus (Delphinidae)

Cuadernos de investigación UNED, 2013
We found a dead whale (Globicephalus macrorhynchus) whose probable cause of death was an internal injury produced by a 1m-long oilfish (Ruvettus pretiosus) that had bitten the whale´s stomach from the inside.
