Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Some Notes on Parasitic Copepoda [PDF]

open access: yesJournal of the Marine Biological Association of the United Kingdom, 1947
The Lernaeopodidae are a highly specialized group of parasitic Copepoda presumably derived from a Caligoid stem, and some clue to their systematic position should be found in their development. Some stages are known in ten genera, but it is only in Achtheres, Salmincola, and Clavella that the whole, or nearly the whole, series of stages has been ...
