Ontogenetic Changes in Feeding Ecology and Habitat of the Damselfish Neoglyphidodon melas at Lizard Island, Great Barrier Reef

  title={Ontogenetic Changes in Feeding Ecology and Habitat of the Damselfish Neoglyphidodon melas at Lizard Island, Great Barrier Reef},
  author={S W Chan},
This study examines ontogenetic shift in habitat and feeding ecology of the black damselfish, Neoglyphidodon melas in three patch reef sites at Lizard Island, Great Barrier Reef. This rarely studied species is unique in its coprophagous relationship with the faeces of the giant clam Tridacna gigas. Distribution and habitat composition between three sites and two reef zones was estimated with 48 Visual Belt and Point Intercept Transects. 80 Focal Animal Studies revealed specific foraging… Expand
Comparative analysis of habitat use and ontogenetic habitat-shifts among coral reef damselfishes
Analysis of patterns of habitat specialisation and ontogenetic shifts in habitat preference among 14 co-existing damselfish species at Lizard Island lagoon on the Great Barrier Reef suggests that habitat loss may not uniformly impact on all life stages. Expand
The ecological significance of giant clams in coral reef ecosystems
The ecological functions of giant clams are elucidated, showing how their tissues are food for a wide array of predators and scavengers, while their discharges of live zooxanthellae, faeces, and gametes are eaten by opportunistic feeders. Expand
The effects of predation on the condition of soft corals
The results of this study indicate that predation can be intense but is not immediately important to soft coral colonies under current climatic conditions. Expand
Comatulids (Crinoidea, Comatulida) chemically defend against coral fish by themselves, without assistance from their symbionts
It is indicated that comatulids chemically defend themselves without assistance from symbionts, and the taste deterrents are not universal and can only be effective against particular predators. Expand
The same but different: stable isotopes reveal two distinguishable, yet similar, neighbouring food chains in a coral reef
Stable isotope compositions were studied in particulate organic matter (POM), zooplankton and different trophic groups of teleosts to compare food chains based on plankton at two sites (lagoon andExpand


Feeding Behavior, Habitat Use, and Abundance of the Angelfish Holacanthus passer (Pomacanthidae) in the Southern Sea of Cortés
Feeding behavior and habitat use of the king angelfish, Holacanthus passer, was studied in the southern Sea of Cortés, México and there was a clear trophic association between C. atrilobata schools and H. passer. Expand
Habitat selection and aggression as determinants of spatial segregation among damselfish on a coral reef
Both habitat selection and interspecific aggression combine to determine the adult distributions of four highly aggressive damselfishes at Lizard Island, northern Great Barrier Reef, suggesting that substratum selection alone is insufficient in explaining the discrete spatial distributions of adults.

Juvenile Groups in a Coral‐Reef Damselfish: Density‐Dependent Effects on Individual Fitness and Population Demography
Although this study demonstrated density-dependent juvenile growth and survival, with consequent fitness effects of group living, it has highlighted considerable inter- and intra-annual variability in these relationships, which will have major consequences for predictions of the effects of juvenile ecology on the demography of organisms.

Size-selective mortality in the juvenile stage of teleost fishes : A review
This review evaluates field and laboratory studies that have examined size-based differences in survival, with emphasis on the juvenile stage of teleost fishes, and results in general support the bigger is better hypothesis, although a number of examples indicate non-selective mortality with no obvious size advantages. Expand
Fecal discharge of zooxanthellae in the giant clam Tridacna derasa, with reference to their in situ growth rate
The population dynamics of zooxanthellae living in the mantle of a giant clam, Tridacna derasa, was studied and it was estimated that about 64 to 89% of the newly formed cells were missing; some of these may have been digested by the clam. Expand
Fish Feces as Fish Food on a Pacific Coral Reef
The fates of 5,975 feces produced by 88 species of reef fishes were monitored at Palau and it was found that fishes ate fish feces in addition to other foods, and most coprophagous interactions were between members of different trophic groups. Expand
Prey-size intake in humbug damselfish, Dascyllus aruanus (Pisces, Pomacentridae) living within social groups.
The size of prey taken by D. aruanus is influenced by the social habit of this species, and the relative position of an individual within its social group influences its subsequent prey intake. Expand
Fishes of the Great Barrier Reef and Coral Sea
This lavishly illustrated volume provides exhaustive coverage of more than 90 percent of the region's reef fishes, including photographs of the juvenile, female and male in species that vary in appearance during their development. Expand
Site familiarity affects escape behaviour of the eastern chipmunk, Tamias striatus
To investigate the effect of familiarity'with the local terrain on the ability to escape predators, we recorded the type of refuge chosen and the distance and time required to reach it, for chipmunksExpand
Behaviors and nutritional importance of coprophagy in captive adult and young nutrias (Myocastor coypus)
It is suggested that coprophagy is quite an effective manner for nutrias to ingest extra protein. Expand
