ABSTRACT. A long-term monitonng study was conducted at Inomote Island (Ryukyu Islands, Japan) to explore the responses of a disturbed adult fish assernblage to the recovery of coral on a large reef degraded by an outbreak of the coral-feeding starfish Acanthaster planci. In 1987, 5 yr after the outbreak, I censused a reef in which aii of the arborescent corals had been broken apart and the reef formation changed into a flat plain of unstructured rubble. Species nchness and numencal density of fishes on the dead reef had decreased severely. Natural recovery of the dead reef was mitiated mainly by larval recruitment of branching Acropora corals in 1989. Since that time, fish species nchness and density on the recovering reef have increased steadily with the increasing percentage cover of live corals. In 1995 to 1997, when the reef had almost 100% live coral cover, most fish assemblage properties (e.g., species numbers and abundances of the collective assemblage and component ecological groups) on the reef did not differ significantly from those on a nearby reef consisting mostly of arborescent Acropora. which had not suffered A. planci predation. The sirnilanty index indicated about 90% resemblance in species composition of the fish assernblages on the recovered and undisturbed reefs. These results demonstrate that the structure of the disturbed fish assemblage had returned to its preperturbation state on the near-completion of coral recovery.

“…Butterflyfishes were surveyed during two passes over each transect. During the first pass, adult butterflyfish within 2m of the transect line were counted while simultaneously deploying the transect tape, following Fowler (1990). On the second pass, all coral colonies (within the 4 m wide belt transect) were carefully searched for the presence of juvenile butterflyfishes.…”

Habitat associations of juvenile versus adult butterflyfishes

et al. 2008

Many coral reef fishes exhibit distinct ontogenetic shifts in habitat use while some species settle directly in adult habitats, but there is not any general explanation to account for these differences in settlement strategies among coral reef fishes. This study compared distribution patterns and habitat associations of juvenile (young of the year) butterflyfishes to those of adult conspecifics. Three species, Chaetodon auriga, Chaetodon melannotus, and Chaetodon vagabundus, all of which have limited reliance on coral for food, exhibited marked differences in habitat association of juvenile versus adult individuals. Juveniles of these species were consistently found in shallow-water habitats, whereas adult conspecifics were widely distributed throughout a range of habitats. Juveniles of seven other species (Chaetodon aureofasciatus, Chaetodon baronessa, Chaetodon citrinellus, Chaetodon lunulatus, Chaetodon plebeius,Chaetodon rainfordi, and Chaetodon trifascialis), all of which feed predominantly on live corals, settled directly into habitat occupied by adult conspecifics. Butterflyfishes with strong reliance on corals appear to be constrained to settle in habitats that provide access to essential prey resources, precluding their use of distinct juvenile habitats.More generalist butterflyfishes, however, appear to utilise distinct juvenile habitats and exhibit marked differences in the distribution of juveniles versus adults.

“…Reef fish ecologists have been divided over the degree of microhabitat specialisation, the degree to which the available microhabitats are partitioned amongst reef fish species and the degree to which the structure of reef fish communities is determined by habitat characteristics (Sale 1991, Williams 1991, Jones & Syms 1998. Within any one family, reef fish species clearly vary both in the degree of microhabitat specialisation (Munday et al 1997, Munday 2000, Bean et al 2002 and in the degree to which they overlap with other fish species (Itzkowitz 1977, Robertson & Lassig 1980, Hourigan 1989, Fowler 1990, Clarke 1994, Green 1996, Öhman et al 1998. If specialisation and overlap are linked, 3 broad patterns are possible.…”

Habitat specialisation and overlap in a guild of coral reef cardinalfishes (Apogonidae)

The nocturnally foraging cardinalfishes are known to exhibit a high degree of fidelity to their daytime resting sites. However, the microhabitats chosen as resting sites, the degree of specialisation on live coral substrata and the degree of overlap among apogonid species have not been described. These patterns potentially affect how declining coral availability will impact the diversity and abundance of apogonid assemblages. Here, microhabitat use, abundances and patterns of cooccurrence are examined for 10 common reef-dwelling apogonids in Kimbe Bay, Papua New Guinea. Nine of the 10 species were strongly associated with live scleractinian corals, with more than 80% of the individuals resting in branching forms. The exception was Apogon nigrofasciatus, a specialist on cave or crevice habitats. Among the available coral species, the vast majority of cardinalfishes were associated with a single coral species (Porites cylindrica), although the degree of specialisation varied among species. Apogon leptacanthus and Sphaeramia nematoptera were almost always only found on P. cylindrica, while Apogon bandanensis, Apogon compressus, Apogon fragilis, Archamia fucata, Archamia zosterophora, Cheilodipterus artus and C. quinquelineatus also used a range of other corals. There was a positive relationship between the range of substratum types used and the number of groups of each species observed. The 9 coral-dwelling apogonids exhibited a high degree of overlap in depth range and in the use of coral microhabitats. Over 75% of aggregations were made up of more than one fish species. The high level of both specialisation and overlap in habitat use suggests that the future biodiversity of cardinalfishes in Kimbe Bay could be linked to the fate of a single coral species.
