Using Photographs in Fishers’ Ecological Knowledge Research: A Review and Field Study on Small‐Scale Fishers’ Knowledge of Coastal Habitats in the Central Mediterranean Sea

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Fishers interact daily with coastal environments, which generate a deep understanding of habitat characteristics, species associations and ecological change. Fishers’ ecological knowledge (FEK) is therefore a critical source of insight for marine science, offering observations that uniquely complement scientific data and, when incorporated ...

Biochemical composition of Echinodermata (Ophiuroidea, Asteroidea) from the abyssal Clarion-Clipperton Fracture Zone

Echinodermata (Ophiuroidea and Asteroidea) were collected by the remotely operating vehicle (ROV) Kiel 6000 (Geomar, Kiel, Germany) and ROV HD14 (Ocean Infinity, Texas, USA) in the eastern Clarion-Clipperton Fracture Zone in 2019 and 2021.

Morphological Characterization and Complete Mitochondrial Genome of a New Epizoic Hexamerous Brittle Star Gymnolophus sexradia sp. Nov

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study describes a new hexamerous epizoic brittle star species, Gymnolophus sexradia sp. nov., from the South China Sea, which lives on crinoid hosts and exhibits a six‐armed body plan possibly indicating fissiparity. Its vertebral and arm plate structures enhance horizontal flexibility for grasping the host, and phylogenetic analysis based on ...

Enodicalix (Diploporita, Aristocystitidae): A new echinoderm genus from the Middle Ordovician of Spain

Geologica Acta, 2020
Restudy of an Ordovician diploporite specimen from the Middle Ordovician of central Spain reveals that the species ‘Calix’ inornatus MELÉNDEZ has four ambulacra, each with two equal facets, an oval hydropore and a smooth thecal surface.

Evolutionary history and recombination in the mitochondrial carrier SLC25 superfamily analyzed by similarities in the exon and transmembrane α‐helix sequences

Protein Science, Volume 35, Issue 8, August 2026.
Abstract Mitochondrial carriers (MCs), which constitute a superfamily also called the solute carrier family 25 (SLC25), are characterized by conserved signature motif sequences and a six‐transmembrane α‐helical transporter domain. They transport a wide variety of substrates ranging from protons, inorganic ions, citric acid cycle intermediates, and ...

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

Remote 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
