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 ...

Human Presence at a Site Explains More Variation than Site MPA Status in Dusky Damselfish (Stegastes nigricans) Antipredator Responses to Humans

Diversity
The growing popularity of ecotourism is increasing human–wildlife interactions in coral reef ecosystems. Although often considered benign, interactions with humans can alter essential antipredator responses. Reef fish exposed to humans often modify their

Living in mixed species groups promotes predator learning in degraded habitats

Scientific Reports, 2021
Living in mix-species aggregations provides animals with substantive anti-predator, foraging and locomotory advantages while simultaneously exposing them to costs, including increased competition and pathogen exposure.

Fine‐Scale Oceanographic Processes Shape Marine Biodiversity Patterns Inferred From Environmental DNA in the Galápagos Islands

Diversity and Distributions, Volume 32, Issue 8, August 2026.
ABSTRACT Aim Uncovering the drivers that shape biodiversity patterns is critical to understanding ecological and evolutionary dynamics. Despite evidence that biodiversity is influenced by processes at different spatial scales, little is known about the role of fine‐scale oceanographic processes on the structure of marine communities.

Anthropogenic stress, bioerosion, and farming damselfish: potential interactions and effects on coral reefs in American Samoa [PDF]

, 2007
Damselfish algal gardens are a prominent feature of coral reefs around the world, and can occupy, in some cases, up to 50 percent of the solid benthic substrate (Klumpp and Polunin, 1989; Sammarco and Williams, 1982).

Corals and Reef‐Dwelling Fish Regulate Carbon Storage and Cycling Processes in Coral Reef Ecosystems

Advanced Science, Volume 13, Issue 41, 22 July 2026.
Coral reefs are biodiversity hotspots, yet their role in carbon storage and cycling remains poorly understood. Using field surveys and modeling in the South China Sea, we reveal the overlooked potential of carbon storage in reef ecosystems and how reef fish, corals, and surface sediment jointly shape reef carbon reservoirs.

Lipoid liver disease and steatitis in a captive sapphire damsel, Pomacentrus pavo [PDF]

Acta Ichthyologica et Piscatoria, 2006
Background. Sapphire damselfish, Pomacentrus pavo (Bloch, 1787) (family Pomacentridae) are reef fish found in tropical and temperate oceans but also are popular aquaria species in commercial and private operations; yet, there remains a paucity of ...

Evidence for Countergradient Growth Adaptation and Jordan's Rule in a Southern Hemisphere Fish, the Atherinopsid Odontesthes regia

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We performed common garden experiments on offspring of the sea silverside Odontesthes regia to characterize thermal growth reaction norms of different populations along the Chilean coast. This showed that the species exhibits local adaptation in the form of countergradient growth adaptation because higher‐latitude southern populations grew faster at ...

Extended exposure to elevated temperature affects escape response behaviour in coral reef fishes [PDF]

PeerJ, 2017
The threat of predation, and the prey’s response, are important drivers of community dynamics. Yet environmental temperature can have a significant effect on predation avoidance techniques such as fast-start performance observed in marine fishes.

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.
