Aim To understand why and when areas of endemism (provinces) of the tropical Atlantic Ocean were formed, how they relate to each other, and what processes have contributed to faunal enrichment.
Historical colonization and demography of the Mediterranean damselfish, Chromis chromis

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.
Compositional constraints and genome evolution

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.

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.
Molecular systematics, zoogeography, and evolutionary ecology of the atlantic parrotfish genus Sparisoma.

- 1 May 2000
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.
REDUCTIONS IN THE MITOCHONDRIAL DNA DIVERSITY OF CORAL REEF FISH PROVIDE EVIDENCE OF POPULATION BOTTLENECKS RESULTING FROM HOLOCENE SEA‐LEVEL CHANGE

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.
BARRIERS TO GENE FLOW IN EMBIOTOCA JACKSONI, A MARINE FISH LACKING A PELAGIC LARVAL STAGE

- 1 February 2000
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.
Herbivory, Connectivity, and Ecosystem Resilience: Response of a Coral Reef to a Large-Scale Perturbation
- T. Adam, R. J. Schmitt, G. Bernardi
- Environmental SciencePLoS ONE
- 25 August 2011
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.
Evolution of coral reef fish Thalassoma spp. (Labridae). 1. Molecular phylogeny and biogeography
- G. Bernardi, G. Bucciarelli, D. Costagliola, D. R. Robertson, J. B. Heiser
- Biology, Environmental Science
- 1 February 2004
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.
STRONG GENETIC DIVERGENCE AMONG POPULATIONS OF A MARINE FISH WITH LIMITED DISPERSAL, ACANTHOCHROMIS POLYACANTHUS, WITHIN THE GREAT BARRIER REEF AND THE CORAL SEA
- S. Planes, P. Doherty, G. Bernardi
- Environmental Science, BiologyEvolution; international journal of organic…
- 1 November 2001
The phylogeography of Acanthochromis polyacanthus is explored with mitochondrial cytochrome b region sequences obtained from 126 individuals representing seven to 12 fish from 13 sites distributed over 12 reefs of the GBR and the Coral Sea, revealing three major clades.
