Atlantic reef fish biogeography and evolution
TLDR
Both historical events and relatively recent dispersal have had a strong influence on Atlantic tropical marine biodiversity and have contributed to the biogeographical patterns observed today; however, examples of the latter process outnumber those of the former.
Historical colonization and demography of the Mediterranean damselfish, Chromis chromis
TLDR
The data suggested a western origin of C. chromis, most likely within the Mediterranean, with a genetic break at the Peloponnese, Greece, with directional and eastbound gene flow between western and eastern groups.
Molecular systematics, zoogeography, and evolutionary ecology of the atlantic parrotfish genus Sparisoma.
TLDR
The molecular data support the view that Sparisoma originated approximately 14-35 million years ago, probably in the tropical western Atlantic, off Brazil; there have been at least four discrete bouts of cladogenesis within the genus, with the most recent one involving four events in both the east and the west Atlantic and across the Atlantic.
VICARIANCE AND DISPERSAL ACROSS BAJA CALIFORNIA IN DISJUNCT MARINE FISH POPULATIONS
TLDR
While dispersal potential was a poor predictor of population structure between Gulf of California and Pacific populations, it was found that population genetic subdivision along the Pacific Coast at Punta Eugenia was always positively correlated with differentiation between Pacific and Gulf ofCalifornia populations.
Compositional constraints and genome evolution
TLDR
It is indicated that noncoding sequences are associated with biological functions and that natural selection plays a more important role in genome evolution than do random events.
Concordant mitochondrial and nuclear DNA phylogenies for populations of the teleost fish Fundulus heteroclitus.
TLDR
Molecular phylogenies using mitochondrial DNA and nuclear alleles of the lactate dehydrogenase B locus were found to be concordant for populations of Fundulus heteroclitus ranging from Canada to Florida, with a clear separation between the northern and southern individuals.
BARRIERS TO GENE FLOW IN EMBIOTOCA JACKSONI, A MARINE FISH LACKING A PELAGIC LARVAL STAGE

  • 1 February 2000
TLDR
Gene flow levels in E. jacksoni were found to be almost identical to those of another species with limited dispersal, Acanthochromis polyacanthus, thus indicating that the lack of a pelagic larval stage combined with barriers to adult dispersal may have had similar effects on these two species.
REDUCTIONS IN THE MITOCHONDRIAL DNA DIVERSITY OF CORAL REEF FISH PROVIDE EVIDENCE OF POPULATION BOTTLENECKS RESULTING FROM HOLOCENE SEA‐LEVEL CHANGE
TLDR
The hypothesis of population size reduction events relative to Holocene sea‐level regression and its consequence on French Polynesia coral reefs is the most parsimonious.
Evolution of coral reef fish Thalassoma spp. (Labridae). 1. Molecular phylogeny and biogeography
TLDR
Data on the spatio-temporal pattern of speciation in the Indo-Pacific indicate that peripheral species have been generated at various times throughout the history of the genus Thalassoma, and that none of the widespread species are relatively young.
Herbivory, Connectivity, and Ecosystem Resilience: Response of a Coral Reef to a Large-Scale Perturbation
TLDR
Evidence of a rapid increase in populations of herbivorous fishes following the most recent perturbation is presented, and it is shown that grazing by these herbivores has prevented the establishment of macroalgae following near complete loss of coral on offshore reefs.
