The importance of sponges and mangroves in supporting fish communities on degraded coral reefs in Caribbean Panama [PDF]

PeerJ, 2018
Fish communities associated with coral reefs worldwide are threatened by habitat degradation and overexploitation. We assessed coral reefs, mangrove fringes, and seagrass meadows on the Caribbean coast of Panama to explore the influences of their ...

Long-term effects of the cleaner fish Labroides dimidiatus on coral reef fish communities. [PDF]

PLoS ONE, 2011
Cleaning behaviour is deemed a mutualism, however the benefit of cleaning interactions to client individuals is unknown. Furthermore, mechanisms that may shift fish community structure in the presence of cleaning organisms are unclear.

Reef fish assemblages impacted by sponges overgrowing corals

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Numerous stressors are driving long‐term declines in coral cover on coral reefs, significantly impacting reef fish biodiversity and community structure. The benthic space made available by declining coral cover is often occupied by increases in other organisms, including macroalgae, encrusting ascidians, and sponges.

Marine invertebrates and fishes exhibit inconsistent body size responses to ocean acidification

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Body size is a fundamental characteristic of all living organisms that determines physiological functions and life‐history traits. Ecological theory predicts that ocean acidification can cause body size reductions, confirmed by several studies reporting miniaturization in ectotherms.

The genome organization of repetitive sequences in the Golden Damselfish, Amblyglyphidodon aureus (Cuvier, 1830) (Family Pomacentridae): insights from extensive pericentric inversions

Caryologia
The genus Amblyglyphidodon (damselfishes) is one of the most distinctive fish groups in the Indo-Pacific coral reef ecosystem. It consists of 11 recognized species, which display complex taxonomic relationships and cryptic lineages across their extensive

Shifting reef fish assemblages along a depth gradient in Pohnpei, Micronesia [PDF]

PeerJ, 2018
Mesophotic coral ecosystems (MCEs) continue to be understudied, especially in island locations spread across the Indo-Pacific Ocean. Pohnpei is the largest island in the Federated States of Micronesia, with a well-developed barrier reef, and steep slopes

Refining a molecular tool kit to capture tropicalization in Mediterranean marine protected areas

Conservation Science and Practice, Volume 8, Issue 5, May 2026.
We assess complementarity and trade‐offs between visual census and eDNA metabarcoding for monitoring fish community changes in MPAs. Abstract Tropicalization, the process by which tropical species expand their ranges poleward due to global ocean warming, is a prominent threat to Mediterranean marine ecosystems, challenging their effective management ...

Dual roles of an algal farming damselfish as a cultivator and opportunistic browser of an invasive seaweed. [PDF]

PLoS ONE, 2014
Herbivory is a fundamental process determining reef resilience, and while algal farming damselfishes can help shape benthic assemblages, an understanding of their contribution to areas outside of defended territories is relatively unexplored.

Nonapeptide cell size differs between male morphs of the West African cichlid, Pelvicachromis pulcher

Journal of Fish Biology, Volume 108, Issue 5, Page 1483-1490, May 2026.
Abstract Alternative male morphs are found in many species of fishes. These morphs often differ in suites of social behaviours, such as aggression and territoriality, associated with alternative reproductive tactics. Such consistent morph‐typical behavioural profiles suggest common differences in underlying neuroendocrine mechanisms.

Rearing duration influences survival rate in the Post‐Larval Capture, Culture and Release of a coral reef fish

Restoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction Juvenile coral reef fish face an initial predation‐induced mortality bottleneck with mortality exceeding 60% within 48 hours of settlement. This intense predation, exacerbated by anthropogenic stressors, limits recruitment and contributes to global declines of reef fish populations. Post‐Larval Capture, Culture, and Release (PCCR),
