Automated object detection based on YOLOv11 for monitoring benthic population dynamics: A new approach combining photogrammetry and open‐source GIS tools applied to sea cucumbers

open access: yesRemote Sensing in Ecology and Conservation, Volume 12, Issue 4, Page 513-530, August 2026.
This research established a new object detection model based on YOLOv11 to recognise benthic organisms, specifically sea cucumbers, by utilising high‐resolution photogrammetric‐based orthomosaics acquired along infralittoral Mediterranean Sea beds. The model demonstrated impressive performance metrics and, when combined with the Deepness plugin for the

Along the Benthic to Holoplanktonic Continuum: Seafloor Affinity Increases Distance‐Decay Rates Among Abyssal Communities

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 8, August 2026.
ABSTRACT Aim Marine species ranges are often large, contributing to relatively high community similarity over space, with decreased ranges expected among taxa that have lower dispersal and/or higher substrate requirements. We tested for a weakening of biogeographic structuring among dispersing abyssal taxa along the benthic to holoplanktonic habitat ...

Benthic megafauna and the functioning of macroalgal forests and urchin barrens

open access: yesOikos, Volume 2026, Issue 7, July 2026.
Two temperate rocky reef food‐web models, representing the trophic diversity of the Mediterranean rocky reef communities, were built for the two stable states: macroalgal forests and barren grounds, which are characterized by opposite amounts of erect macroalgal biomass.

Free Sterol Composition of Deep-Sea Holothurian cf.

open access: yesNatural Product Communications, 2022
The free sterol fraction from the deep-sea holothurian Orphnurgus cf glaber Walsh, 1891, has been isolated and studied by GC–MS. Sterols containing Δ 7 , Δ 0 , Δ 5 , polyunsaturated and 5,8-epidioxy modified cores were found.

On Some Plymouth Holothurians [PDF]

open access: yesJournal of the Marine Biological Association of the United Kingdom, 1914
Some of the specific and differential characters of these two species have already been enumerated by Pace (1). Subsequently Norman (2) denied that these two forms were different, so that the literature on them was left in an unsatisfactory state. On investigating these two forms, however, I have obtained sufficient evidence-from the characters of the ...

Holothurian sclerites from the Triassic of Jordan and their stratigraphic importance

open access: yes, 1996
. Holothurian selerites are some of the most stratigraphically important microfossils of the middle Triassic of Jordan. Stratigraphically and palaeogeographically important faunas have been obtained by dissolving Triassic carbonate rocks with a dilute ...

New evidence for a cosmopolitan holothurian species at deep-sea reducing environments

open access: yes, 2022
The deep-sea holothurian Chiridota heheva Pawson & Vance, 2004 was recently recognised as a cosmopolitan species which exploits the organic enrichment at three types of deep-sea reducing environments: hydrothermal vents, cold seeps, and organic falls.
