Evidence of ontogenetic migration from mangroves to coral reefs by black-tail snapper Lutjanus fulvus: stable isotope approach
TLDR
Stomach content and stable isotope analyses of L. fulvus showed that specimens from mangroves fed on mangrove-associated prey, whereas those from the coral reef took coral reef- associated prey, indicating that the species undergoes ontogenetic changes in resource use from theMangroves to the coral Reef, i.e. coral reef individuals did not migrate to the mangroaves to feed.
Male maturity, number of sperm, and spermatophore size relationships in the coconut crab Birgus latro on Hatoma Island, southern Japan
TLDR
Female coconut crabs display a size-dependent reproductive output, as is reported for other species of anomurans, and Larger male coconut crabs have a higher number of sperm in both the vasa deferentia and testis.
Relationship between pelagic larval duration and abundance of tropical fishes on temperate coasts of Japan.
TLDR
A negative correlation between PLD and the abundance of some species of pelagic and demersal spawners suggests the presence of reproductively active fishes in northern subtropical and even in temperate waters.
Variability in nursery function of tropical seagrass beds during fish ontogeny: timing of ontogenetic habitat shift
TLDR
Overall, the function of the seagrass bed nursery changed with juvenile body size, with marginally higher survival and significantly greater growth rates during early juvenile stages in seagRass beds compared to coral reefs.
Isolation and characterization of stress-responsive genes from the scleractinian coral Pocillopora damicornis
TLDR
Reverse transcription-mediated PCR showed that the expression of pPd9-1 was also increased by elevated temperature, but not by reduced salinity, suggesting that red soil may cause protein denaturation in the coral.
Spatial variability in habitat associations of pre- and post-settlement stages of coral reef fishes at Ishigaki Island, Japan
TLDR
Two patterns are highlighted: the first minimizes the transition time between the larval pelagic stage and acquisition of a benthic reef habitat, the latter leading immediately to a juvenile lifestyle, and the second pattern is characterized by high settlement habitat selectivity by larvae and/or differential mortality immediately after settlement.
