Coral cover and reef fishes in the Karang Takat patch reef, Sumenep, Madura, Indonesia [PDF]

BIO Web of Conferences
Karang Takat Patch Reef Sumenep is a coral reef ecosystem located between Gili Labak Island and Gili Genting Island, which means that the coral reef ecosystem is directly impacted by activities that occur on both islands.

A Time-Extended (24 h) Baited Remote Underwater Video (BRUV) for Monitoring Pelagic and Nocturnal Marine Species

Journal of Marine Science and Engineering, 2020
Baited remote underwater video systems (BRUVs) are efficient devices for remotely characterising the assemblage and relative density of fishes and other marine organisms.

When mesophotic meets shallow: First records of deep‐associated reef fishes in a well‐studied tropical bay under the influence of spring–summer upwelling

Journal of Fish Biology, EarlyView.
Abstract We document the first records of reef fishes typically associated with mesophotic environments on shallow (<10 m) coral reefs inside a well‐studied tropical bay. The vermilion snapper Rhomboplites aurorubens and the pygmy angelfish Centropyge aurantonotus, usually restricted to deeper (>40 m) shelf habitats along the Brazilian coast, were ...

Winter Type, Mediated by Land‐Surface Processes, Controls Seasonal Discharge Variability in Culturally Critical Ecosystems in the US's Upper Midwest

Hydrological Processes, Volume 40, Issue 8, August 2026.
Results showed snowpack to be the primary driver of springtime flow in the low‐relief, humid Upper Midwest U.S., with overall winter precipitation and thawing acting as key secondary drivers impacting hydrological flux partitioning across the land surface.

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

Journal of Animal Ecology, Volume 95, Issue 8, Page 1386-1400, August 2026.
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 ...

Size and Ecology of a Giant Pavona clavus Coral Colony in the Kingdom of Tonga

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Some individual coral colonies can grow to immense sizes and survive for centuries, offering rare insight into how corals persist over long time scales. This study documents one of the largest coral colonies ever recorded—a colossal Pavona clavus in Tonga—and shows that, despite being dominated by a single species, it supports fish communities and ...

Variability in Fish Environmental DNA Concentration in Coastal Ecosystems at Hierarchical Levels: Focusing on the Magnitude, Structure, and Environmental Dependence

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Differences in eDNA concentration heterogeneity under the TPL framework suggest a concentration‐dependent survey design to minimize noise in eDNA quantification. In addition, whilst spatial and temporal variations in eDNA concentration could be primarily determined by ecological factors such as the distribution and dynamics of individuals, variations ...

Guild Structure in Coral Reef Fishes Does Not Conform to Competitive Exclusion–Based Assembly Rules

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We tested classic competition‐based community assembly predictions in a lagoonal coral reef fish community using feeding guild data and null models. Species within guilds commonly occurred together, and guild composition differed strongly among reefs. Local competition does not translate into clear community‐level structure in this system.

Artisanal fishing of spiny lobsters with gillnets — A significant anthropic impact on tropical reef ecosystem

Global Ecology and Conservation, 2015
Artisanal fishing activity with gillnets to capture the spiny lobster is a common practice along the coastal reefs of Brazil. This research aims to understand the impact that this artisanal fishing practice is having on the coastal reef systems analysing

Contrasting cryptofaunal responses to seabird nutrient inputs illuminate coral reef productivity pathways

Ecology, Volume 107, Issue 7, July 2026.
Abstract Nutrients moving across ecosystems can propagate through food webs via distinct trophic pathways. Their integration into food webs is often mediated by small, abundant taxa that channel subsidies from primary producers to higher trophic levels.
