Deep learning‐based super‐resolution reconstruction and improved YOLOv9 for efficient benthos detection: a case study at Lake Hamana, Japan

Remote Sensing in Ecology and Conservation, Volume 12, Issue 5, Page 712-726, October 2026.
This study presents a UAV‐based framework that integrates deep learning‐based super‐resolution reconstruction and an enhanced YOLO detector to improve centimetre‐scale benthic organism monitoring. Using hermit crabs in Lake Hamana, a coastal lagoon in Japan, as a case study, the method substantially enhanced small‐object detection performance ...

Target Capture of Ancient Shell DNA Enables Phylogenetic Reconstruction of Deep‐Sea Molluscs

Molecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT Target capture is widely used to enrich endogenous DNA from calcium phosphate skeletal material in vertebrates, but its performance on calcium carbonate hard parts widely produced by invertebrates remains poorly understood. Here, we compared DNA recovery from four fresh and 12 ancient (eight radiocarbon‐dated to 1671–1135 years old before ...

Nitrate and UV-absorbance spectra from remotely operated vehicle (ROV) surveys during the ARTofMELT2023 expedition

Nitrate and UV-absorbance spectra were measured by a SUNA V2 UV-spectrometer (Satlantic) mounted in the sensor skid of a remotely operated vehicle (ROV) during the ARTofMELT2023 expedition in May and June 2023. The instrument header is SATSLS0847.

A novel approach for in situ benthic habitat characterization

Limnology and Oceanography: Methods, Volume 24, Issue 9, September 2026.
Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Clionaidae From Northeastern Brazil: A New Species of Clionaopsis (Rützler 2002), Redescription of Spheciospongia symbiotica (Hechtel 1983), and New Records of Cervicornia cuspidifera (Lamarck 1815)

New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
The family Clionaidae d’Orbigny, 1851, includes excavating sponges characterized by tylostyles and a diverse range of microscleres, including spirasters, amphiasters, microxeas, spiral microstrongyles, and derivatives lacking altogether. Despite recent taxonomic advances, generic boundaries within the family remain problematic due to overlapping ...
