Effects of the Allelopathic Macroalga <i>Galaxaura divaricata</i> on the Foraging Behaviors of Reef Fishes Across Herbivorous and Nonherbivorous Feeding Guilds. [PDF]
Ecol EvolHerbivorous fishes reduce their feeding with allelopathic macroalga: Galaxaura, while nonherbivorous fishes didn't change their feeding with Galaxaura. Feeding reduction with Galaxaura differed across fish species and may vary by morphology or chemical resistance of different fish species.

Limited Evidence for Depth Specialism in Isolated Seamount Reef Predators. [PDF]
Ecol EvolWe investigated how depth influences predatory fish assemblages on seamount reefs in the Coral Sea using remotely operated vehicle surveys across a 100 m depth gradient. Predator abundance and species richness declined significantly with depth; yet assemblage composition remained largely consistent, suggesting many taxa utilise a broad depth range ...

Use of Citizen Science to Determine Prey Partitioning Between Two Coastal Raptors. [PDF]
Ecol EvolIn Australia, Eastern Osprey (Pandion haliaetus cristatus) and White‐bellied Sea‐Eagle (Haliaeetus leucogaster) occupy the same ecological niche and are suspected of partitioning prey resources. This study investigated this through evaluating the breadth, overlap and partitioning of diets recorded from social media posts.

Dietary resilience of coral reef fishes to habitat degradation. [PDF]
J Anim EcolMetabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Lack of mtDNA differentiation among hamlets ( Hypoplectrus , Serranidae) [PDF]
Marine Biology, 2004 The hamlets are a group of vividly colored fish species of the Serranidae family differentiated only by the color pattern of the body. Although there are divergent views about hamlet taxonomy, experimental and field observations have shown a strong assortative mating, justifying a species status for the different color morphs. Here we analyze the level

Associations between fishes (Actinopterygii: Teleostei) and anthozoans (Anthozoa: Hexacorallia) in epipelagic waters based on in situ records. [PDF]
J Fish BiolAbstract We formally describe the association of fishes and anthozoans in epipelagic waters, extending this relationship to beyond the benthos. In situ observations and photographs of Aluterus schoepfii, Ariomma regulus, Caranx cf. latus and Brama spp.
