New record of the Japanese roughshark, Oxynotus japonicus Yano et Murofushi, 1985 (Elasmobranchii: Squaliformes: Oxynotidae) in Taiwan [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2016
A specimen of the rare Japanese prickly dogfish, known also as the Japanese roughshark, Oxynotus japonicus Yano et Murofushi, 1985, was recently collected from the north-eastern Taiwan at the Daxi fish market. It represents the first record of the family,

Composition of the diacyl glyceryl ethers and triglycerides of the flesh and liver of the dogfish (Squalus acanthias)

open access: yesJournal of Lipid Research, 1965
The major lipids of the dogfish (Squalusacanthias) are the diacyl glyceryl ethers and triglycerides. These classes of compounds in the flesh (dorsal section) and liver were separated by thin-layer chromatography.

Metabolism of glycerol ether-containing lipids in dogfish (Squalus acanthias)

open access: yesJournal of Lipid Research, 1968
Dogfish (Squalus acanthias) received intrahepatic injections of either palmitic acid-1-14C or chimyl alcohol-1-14C. The lipids of the liver were then analyzed for incorporated radioactivity.The experiments with labeled palmitic acid demonstrated that ...

Exploring the Recent Abundance of Spiny Dogfish in the Gulf of Maine [PDF]

open access: yes, 2017
I received a 2016 Summer Undergraduate Research Fellowship (SURF) grant to work alongside commercial fishermen on the New Hampshire coastline. Declining populations of traditional groundfish species, such as Atlantic cod, have forced New Hampshire ...

Coupling the neural and physical dynamics in rhythmic movements [PDF]

open access: yes, 1996
A pair of coupled oscillators simulating a central pattern generator (CPG) interacting with a pendular limb were numerically integrated. The CPG was represented as a van der Pol oscillator and the pendular limb was modeled as a linearized, hybrid spring ...

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

In the quest of the optimal chondrichthyan for the development of collagen sponges for articular cartilage

open access: yesJournal of Science: Advanced Materials and Devices, 2021
The limited capability of articular cartilage to self-repair renders its regeneration a formidable challenge. In the quest of the optimal material for cartilage scaffold fabrication, the use of collagen type II has been advocated, but its optimal source ...

Age and growth of spiny dogfish (Squalus acanthias) in the Gulf of Alaska: analysis of alternative growth models [PDF]

open access: yes, 2010
Ten growth models were fitted to age and growth data for spiny dogfish (Squalus acanthias) in the Gulf of Alaska. Previous studies of spiny dogfish growth have all fitted the t0 formulation of the von Bertalanffy model without examination of alternative

Environmental Policy Without Implementation? A Review of Factors Contributing to Implementation Gaps in Low‐ and Middle‐Income Countries

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT The sound formation of robust environmental policies is increasingly important for low‐ and middle‐income countries (LMICs) to achieve their national objectives and international commitments. However, policy implementation can be complex, and environmental policies may not be prioritised given other critical socio‐economic development issues ...

A Changing Gulf of Maine: Investigating the Role of Benthic Water Temperature in Determining the Timing of Spiny Dogfish (Squalus acanthias) Arrival and Departure in the Gulf of Maine [PDF]

open access: yes, 2017
Spiny Dogfish (Squalus acanthias) is a highly migratory elasmobranch that undergoes annual migrations along the East Coast of the United States. Spiny dogfish have been studied extensively on the West Coast, but little information currently exists on the
