To clarify the feeding habits of fishes in tropical seagrass beds on coral reefs, the gut contents of 53 fish species, collected in an Enhauls acoroides-dominated bed at Iriomote Island, southern Japan, were examined. Ontogenetic changes in food preference were recognized in 9 species, including lethrinids, mullids, pomacentrids, labrids, and scarids. Cluster analysis based on dietary overlaps showed that the seagrass fish assemblage comprised seven feeding guilds (small-crustacean, large-crustacean, plant, detritus, hard-shelled mollusc, fish, and planktonic-animal feeders). Of these, small-crustacean feeders were the most abundantly represented. On the other hand, planktonic-animal and hard-shelled mollusc feeders were each represented by only two species. Compared with previous studies on the feeding habits of temperate seagrass fishes, the present fish assemblage was characterized by larger species numbers of detritivores, herbivores, and piscivores and fewer planktonic-animal feeders.read more

Integrating ecological roles and trophic diversification on coral reefs: multiple lines of evidence identify parrotfishes as microphages
TL;DR: A novel view of parrotfish feeding biology provides a unified explanation for the apparently disparate range of feeding substrata used by parrotfishes, and integratesParrotfish nutrition with their ecological roles in reef bioerosion and sediment transport.

High connectivity of Indo-Pacific seagrass fish assemblages with mangrove and coral reef habitats
TL;DR: It is indicated that Indo-Pacific seagrass beds play an important fish nursery role, which is influenced by the availability of nearby reef and mangrove habitats, but also suggests that successful management requires local-level knowledge of habitat interactions to successfully enhance or conserve fish assemblages.

Diet composition of carnivorous fishes from coral reef lagoons of New Caledonia
Michel Kulbicki,Yves-Marie Bozec,Yves-Marie Bozec,P. Labrosse,Yves Letourneur,Gérard Mou-Tham,Laurent Wantiez +6 more
TL;DR: A total of 212 carnivorous coastal fish species from New Caledonia, represented by 7335 individuals, were analysed for their diet, with nekton increased in importance with fish size, whereas crustaceans decreased and molluscs presented a dome shaped relationship.

Diel trophic structuring of seagrass bed fish assemblages in the Wakatobi Marine National Park, Indonesia
TL;DR: It is proposed that diel changes in seagrass fish assemblages are predominantly structured by food availability, although other factors such as increased night-time shelter provision were also found to be important albeit to a much lesser extent.

TL;DR: This paper developed generalized scenarios of this form of tropicalization and its potential effects on the structure and functioning of globally significant and threatened seagrass ecosystems, through poleward shifts in tropical fish and herbivores.

TL;DR: A guild is defined as a group of species that exploit the same class of environmental resources in a similar way and has a position comparable in the classification of exploitation patterns to the genus in phylogenetic schemes.

Grazing Effect on Sea Grasses by Herbivorous Reef Fishes in the West Indies
TL;DR: It is the author's opinion that if the pre-Columbian population of the green turtle could be restored and its fishery properly regulated, the enormous production of the sea grasses in the Caribbean region could be realized more fully for the benefit of man.
