Application of pop-up satellite archival tag technology to estimate postrelease survival of white marlin (Tetrapturus albidus) caught on circle and straight-shank (“J”) hooks in the western North Atlantic recreational fis [PDF]

open access: yes, 2005
Short-duration (5- or 10-day) deployments of pop-up satellite archival tags were used to estimate survival of white marlin (Tetrapturus albidus) released from the western North Atlantic recreational fishery.

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Fossil tuna vertebrae punctured by istiophorid billfishes

open access: yesJournal of Vertebrate Paleontology, 2004
Extant billfishes of the family Istiophoridae (Teleostei: Perciformes: Scombroidei) often use their rostra to impale or slash prey (Gudger, 1940; Nakamura, 1983; Frazier et aI., 1994). Although it is generally assumed that fossil and living representatives of the same species have similar behaviors and physiology (Fierstine, 200I), there is no docu ...

Spatial Variation in Pelagic Wildlife Assemblages in the Ascension Island Marine Protected Area: Implications for Monitoring and Management

open access: yesFrontiers in Marine Science, 2021
Bathymetric features such as islands and seamounts, as well as dynamic ocean features such as fronts often harbour rich marine communities. We deployed mid-water baited remote underwater video systems on three expeditions in Ascension Island’s Exclusive ...

Comparison of Conventional, Rake, and Sonar‐Based Biophysical Habitat Measurements in a Shallow Ontario River

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Knowledge of habitat availability is critically important for the management and recovery of freshwater species. Quantifying habitat availability often requires fine‐scale sampling at point‐based locations across a large geographic extent, which can be laboursome.

An indexed bibliography of papers on tagging of tunas and billfishes [PDF]

open access: yes, 1993
Two working parties, the Working Party on Tuna Tagging in the Pacific and Indian Oceans and the Working Party on Tuna Tagging in the Atlantic and Adjacent Seas, were formed by the Food and Agriculture Organization (FAD) of the United Nations in 1966 ...

Inhibition of PHF1 promotes ferroptosis via IRES‐dependent Snail translation regulation in pancreatic ductal adenocarcinoma

open access: yesVIEW, EarlyView.
PHF1 is a known epigenetic regulator involved in transcriptional silencing in cancer. In this study, we identified PHF1 as an oncogene that promotes PDAC progression and demonstrated that its inhibition induces ferroptosis. Mechanistically, PHF1 physically interacts with the FBL/NOP56/NOP58 snoRNP complex to enhance the IRES‐dependent translation of ...
