Stable Isotope Composition of Skin Layers Confirms Trophic Differentiation of Baird's and Sato's Beaked Whales (Berardius spp.) in the Western North Pacific. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Closely related whale species can appear similar yet occupy distinct ecological niches. Sato's beaked whale (Berardius minimus) was only recently recognized as a separate species and was previously grouped with Baird's beaked whale (Berardius bairdii), limiting our understanding of their ecological differences.

Assessment of a Social Media-Based Method for Determining Raptor Diet. [PDF]

Ecol Evol
This study mined social media as a citizen science method to reduce the time burden and biases associated with recording accurate diet information for predators. In total, 1985 prey observations were recorded of two Australian coastal raptors and were used to produce diet profiles that were compared by region, social media platform, and against other ...

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 ...

The Motion Picture: Leveraging Movement to Enhance AI Object Detection in Ecology. [PDF]

Ecol Evol
As AI methods become increasingly popular to automatically analyse ecology data, we investigate using movement information as a means to improve traditional object detection approaches (which are limited to static image information only) on over 35,000 annotated images from 1480 terrestrial, marine and freshwater locations, the most extensive ...

The fossil vertebrate primary type specimens in the collection of the University of Otago Department of Geology. [PDF]

J R Soc N Z
ABSTRACT The 47 vertebrate type specimens held in the University of Otago Geology Department are catalogued in detail. A short history of the collection is followed by lists of the type specimens under the Classes Actinopterygii, Reptilia, Aves and Mammalia. A fish trace‐fossil is included at the end of the Actinopterygii.

Length–weight relations of 39 continental-shelf and deep-water fishes (Actinopterygii) from northwestern Gulf of México [PDF]

Acta Ichthyologica et Piscatoria, 2023
Fishes from the northwestern Gulf of Mexico were surveyed during four oceanographic campaigns (February and October 2016, June and September 2017) using a shrimp trawl net and benthic sled net in 20 locations at depths that ranged from 43 to 3608 m ...

Northernmost records of Gadella maraldi (Actinopterygii: Gadiformes: Moridae) in the north-eastern Atlantic [PDF]

Acta Ichthyologica et Piscatoria, 2012
Four specimens of Gadella maraldi (Moridae) were captured in the north-eastern Atlantic. One specimen was caught off the Galician coast (north-western Spain) and three individuals on the Porcupine Bank (off western Ireland). Morphometric measurements and

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.

New Record of Gadella jordani and Redescription of Physiculus japonicus (Pisces: Moridae) in Korea [PDF]

Animal Systematics, Evolution and Diversity, 2016
We describe the morphological characteristics of two morids, Gadella jordani and Physiculus japonicus, belonging to the order Gadiformes, based on Korean specimens collected from the Korean ocean. Two specimens of Gadella jordani was first collected from
