Assessment of a Social Media-Based Method for Determining Raptor Diet. [PDF]
Ecol EvolThis 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 EvolThe 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 EvolAs 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 ZABSTRACT 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.

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.

Aquaculture, Fish and Fisheries, Volume 3, Issue 3, Page 268-286, June 2023., 2023 This study compares the gut contents of snapper in soft‐sediment habitats within and outside of New Zealand green‐lipped mussel farms. Snapper within mussel farms were consistently found to have consumed different prey groups compared to the control snapper. The prey groups consumed by snapper in mussel farms are likely more nutritious and therefore 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.

New records of Morid fishes (Teleostei: Gadiformes) from the southermost tip of South America
Scientia Marina, 1999 Three species of morid fishes were collected during the Expedition Antarktis XIII/4 of RV "Polarstern" at the southernmost tip of South America, on the slope east of Isla Nueva, Southern Chile (ca.

A new species of Sarcotaces (Copepoda: Cyclopoida: Philichthyidae) from Antimora rostrata (Actinopterygii: Gadiformes: Moridae) [PDF]
Acta Ichthyologica et PiscatoriaParasitic copepods of the genus Sarcotaces occur in galls inside the skeletal musculature of fishes. The gall, hosting a highly metamorphosed drop-shaped female contains also a black fluid capable of staining the fish tissues during filleting.
