Simulation modeling of the Adjustable Buoyancy Device for open ocean low trophic aquaculture, part I: Test of a submersible long tube unit

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Open‐water low‐trophic aquaculture (LTA) is a sustainable method for producing ocean‐based food and providing ecosystem services. An effective system design is critical for mitigating risks posed by deep ocean forces. Developing submersible cultivation technology requires quantitative risk analysis and modeling to address offshore challenges ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
