Variability in abundance of temperate reef fishes estimated by visual census. [PDF]

PLoS ONE, 2013
Identifying sources of sampling variation and quantifying their magnitude is critical to the interpretation of ecological field data. Yet, most monitoring programs of reef fish populations based on underwater visual censuses (UVC) consider only a few of ...

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

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 ...

Aggregative Behaviour of Spiny Butterfly Rays (Gymnura altavela, Linnaeus, 1758) in the Shallow Coastal Zones of Gran Canaria in the Eastern Central Atlantic

Animals, 2023
The presence of spiny butterfly rays, Gymnura altavela, in waters less than 20 m deep off the Canary Islands shows marked seasonality, with relatively high abundances in the summer and autumn.

Rarely Reported Cryptobenthic Fish in Marine Caves of the Eastern Mediterranean Sea

Journal of Marine Science and Engineering, 2021
Data on the distribution and ecology of cryptobenthic fish of marine caves in the Mediterranean Sea are extremely scarce but necessary for scientists and marine managers alike in order to understand these fish’s ecological role and assess their ...

The Role of Fish Aggregating Devices (FADs) in Juvenile Fish Dispersal along the North-Western Coast of Sicily

Journal of Marine Science and Engineering, 2023
Fish aggregating devices (FADs) are used worldwide to attract fish. Previous studies revealed that FADs affect the distribution and dispersal patterns of juvenile fish species during their life stage under floating objects. In this study, we hypothesised

The good and the better, sampling tropical intertidal rock pool fishes: a comparison between visual census vs. rock pool bailing method

Ciencias Marinas, 2023
Numerous sampling methods have been applied to study intertidal rock pool fishes. There is limited information comparing the performance and suitability of such methods, which complicates comparisons between studies.

The Taming of Smeagol? A New Population and an Assessment of the Known Population of the Critically Endangered Pulmonate Gastropod Smeagol hilaris (Heterobranchia, Otinidae)

Diversity, 2023
The genus Smeagol consists of five named species of air-breathing marine slugs (restricted to southern Australia and New Zealand) and three undescribed taxa from southern Japan. Only one species, S. hilaris, is known to be from New South Wales (NSW), and

Comparative Study of Marine Cave Communities in a Protected Area of the South-Eastern Aegean Sea, Greece

Journal of Marine Science and Engineering, 2022
Although more than 600 marine caves have been recorded so far along the Greek coasts of the Aegean Sea (Eastern Mediterranean), only a few have been systematically studied for their biodiversity. In this study, the benthic communities of six marine caves

Combining Methods to Better Estimate Total Fish Richness on Temperate Reefs: The Case of a Mediterranean Coralligenous Cliff

Journal of Marine Science and Engineering, 2021
Coralligenous habitat is considered as one of the most important special habitat types in the Mediterranean; however, due to its inaccessibility, little is known about it, although it is considered as one of the Mediterranean’s richest habitats in terms ...
