A virus-like agent associated with neurofibromatosis in damselfish [PDF]

Diseases of Aquatic Organisms, 2002
Damselfish neurofibromatosis (DNF) is a transmissible disease involving neurofibromas and chromatophoromas affecting bicolor damselfish Stegastes partitus on Florida reefs. Analysis of genomic DNA by Southern blotting techniques demonstrated the presence of a group of extrachromosomal DNAs in tumors from fish affected with DNF but not in healthy ...

Fatal Hemorrhagic Septicemia in Common Guitarfish (Rhinobatos rhinobatos) Caused by Photobacterium damselae Subsp. damselae in a Controlled Environment. [PDF]

J Fish Dis
ABSTRACT Elasmobranchs, including sharks and rays, are commonly housed in public aquariums due to their ecological significance and educational value. The common guitarfish (Rhinobatos rhinobatos), currently listed as ‘Critically Endangered’ by the IUCN, is particularly susceptible to population declines due to overfishing and bycatch.

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, EarlyView.
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

Effects of "Reduced" and "Business-As-Usual" CO2 Emission Scenarios on the Algal Territories of the Damselfish Pomacentrus wardi (Pomacentridae). [PDF]

PLoS ONE, 2015
Turf algae are a very important component of coral reefs, featuring high growth and turnover rates, whilst covering large areas of substrate. As food for many organisms, turf algae have an important role in the ecosystem.

Semi‐automated MicroED system unveils multiple polymorphs in fish‐derived guanine crystals

Acta Crystallographica Section C, EarlyView.
A semi‐automated MicroED data collection and processing system was established and shown to be suitable for the structural investigation of submicrometer‐scale biogenic crystals.Certain fish display silvery or blue colour, not through pigments, but through specialized guanine crystals that exist within iridophore cells in their skin. Within these cells,

Domestication via the commensal pathway in a fish-invertebrate mutualism

Nature Communications, 2020
It has been hypothesized that domestication can occur through the ‘commensal pathway’ in which the domesticate takes advantage of a niche created as a byproduct by the domesticator. Here, Brooker et al.

Effects of ocean acidification on learning in coral reef fishes. [PDF]

PLoS ONE, 2012
Ocean acidification has the potential to cause dramatic changes in marine ecosystems. Larval damselfish exposed to concentrations of CO(2) predicted to occur in the mid- to late-century show maladaptive responses to predator cues.

Ocean acidification, more than warming or heatwaves, constrains shoaling behaviour in a range‐extending fish through habitat simplification

Journal of Animal Ecology, EarlyView.
We show that ocean acidification, more than warming or marine heatwaves, alters shoaling behaviour indirectly by simplifying reef habitat and reducing population densities and shoal sizes. Because fish behaviour can be strongly mediated by shoal size, climate‐driven habitat change may reshape social dynamics that influence how range‐extending fishes ...

Coral-dwelling fish moderate bleaching susceptibility of coral hosts.

PLoS ONE, 2018
Global environmental change has the potential to disrupt well established species interactions, with impacts on nutrient cycling and ecosystem function. On coral reefs, fish living within the branches of coral colonies can promote coral performance, and ...
