Aggregation behavior of the grey reef shark, Carcharhinus amblyrhynchos, at Johnston Atoll, Central Pacific Ocean
Free-ranging female grey reef sharks, Carcharhinus amblyrhynchos, were observed forming daily aggregations offshore Sand Island, Johnston Atoll between March and late May from 1992 to 1995. Daily
Kinetic control of skeletal Sr/Ca in a symbiotic coral: Implications for the paleotemperature proxy
Modeling of past climates is critically dependent on estimates of past sea surface temperatures (SSTs), for which one of the principal techniques used is the measurement of Sr/Ca ratios in corals
Trophic biology of herbivorous reef fishes: alimentary pH and digestive capabilities
  • P. Lobel
  • Environmental Science
  • 1 October 1981
TLDR
The trophic relationship between fishes and algae of specified morphologies are predicted by extrapolation from the experimental results on algae vulnerable to acid lysis or trituration.
Possible species specific courtship sounds by two sympatric cichlid fishes in Lake Malawi, Africa

    Environmental Biology of Fishes
  • 1 August 1998
TLDR
These cichlids produced courtship sounds that were distinct by individual pulse durations and by pulse repition rate in a call that were significantly different in pulse rate and individual pulse duration between species.
Environmental influences on the diel timing of spawning in coral reef fishes
TLDR
Spawning of most fishes with daytime spawning peaks was correlated with local changes in current direction and predatory risks, suggesting responses designed to reduce the mortality of propagules and adults.
Effects of depth, habitat, and water motion on the abundance and distribution of ciguatera dinoflagellates at Johnston Atoll, Pacific Ocean
TLDR
This study provides a characterization of the ciguatera dinoflagellate community across a variety of coral reef habitats, contributing to an accurate and coherent characterization ofThe population dynamics of this important din oflageLLate community.
Foraging by the herbivorous parrotfish Sparisoma radians
TLDR
Comparison of laboratory results with field feeding behavior shows that inclusion of plants in the diet is not related directly to preference rank, availability or survival value, but that the fish deliberately eat a variety of plants presumably which maintains balanced diet.
Differences in pectoral fin spine morphology between vocal and silent clades of catfishes (Order Siluriformes): Ecomorphological implications
TLDR
The first phylogenetic evidence for stridulation mechanism loss within catfishes is presented, and the repeated presence of silence and vocal taxa, short and long spines, and ecotype shifts within clades are revealed.
Lack of mitochondrial genetic structure in hamlets (Hypoplectrus spp.): recent speciation or ongoing hybridization?
TLDR
The presence within hamlets of two divergent mtDNA clades suggests a longer history during which hybridization and gene flow have prevented the differentiation of hamlet colour morphs, at least in neutral genetic markers.
