Comparison of Environmental DNA Metabarcoding and Underwater Visual Census for Assessing Macrobenthic Diversity [PDF]

Biology
The rapid advancement of environmental DNA (eDNA) technology has transformed ecological research, particularly in aquatic ecosystems. However, the optimal sampling matrix (e.g., water or sediment) and the potential for eDNA to replace or complement ...

Comparing environmental DNA metabarcoding and underwater visual census to monitor tropical reef fishes [PDF]

Environmental DNA, 2021
Environmental DNA (eDNA) analysis is a revolutionary method to monitor marine biodiversity from animal DNA traces. Examining the capacity of eDNA to provide accurate biodiversity measures in species‐rich ecosystems such as coral reefs is a prerequisite ...

Cameras or Divers? How Baited Remote Underwater Videos and ‘Long Swims’ Underwater Visual Census Complement Each Other on Coral Reefs [PDF]

Ecology and Evolution
Conventional methods for surveying coral reefs, such as underwater visual census (UVC), often underestimate large‐bodied, mobile, or cryptic fish species due to limitations in diver mobility and visual detection. To address these limitations, rapid timed

Video transects as a complement to underwater visual census to study reserve effect on fish assemblages [PDF]

Aquatic Biology, 2013
The present study focuses on the use of diver-operated video (DOV) as a tool to evaluate the impact of a marine reserve on a fish assemblage, in comparison to underwater visual census (UVC).

Assessing the effectiveness of no-take zones on fish populations in the Marine Natural Park of Cap Corse and Agriate, Northwestern Mediterranean Sea. [PDF]

PLoS ONE
No-take zones (NTZs) are expected to rebuild exploited fish populations, yet their performance is rarely assessed with species-level indicators. We quantified the reserve effect of the Nonza-San Fiurenzu NTZ (24.2 km2) inside the Marine Natural Park of ...

Shifts in Small Fish Community Caused by Coral Cover Variation at a Remote Reef in the South China Sea [PDF]

Ecology and Evolution
Global coral reef fish biodiversity is undergoing a severe decline driven by both natural and anthropogenic disturbances. However, the biodiversity and ecological functions of small fishes have long been underestimated, mainly because small fishes are ...

eDNA metabarcoding as a biomonitoring tool for marine protected areas.

PLoS ONE, 2021
Monitoring of marine protected areas (MPAs) is critical for marine ecosystem management, yet current protocols rely on SCUBA-based visual surveys that are costly and time consuming, limiting their scope and effectiveness.
