The conservation significance of the IAA is discussed and the need for cross-taxon comparative studies using newly developed analytical approaches well suited to the challenges of historical inference in this region is highlighted.
Paradigm shifts in marine fisheries genetics: ugly hypotheses slain by beautiful facts
- L. Hauser, G. Carvalho
- Environmental Science
- 1 December 2008
An important implication of genetic structuring and the potential for adaptive divergence is that locally adapted populations are unlikely to be replaced through immigration, with potentially detrimental consequences for the resilience to environmental change ‐ a key consideration for sustainable fisheries management.
Loss of microsatellite diversity and low effective population size in an overexploited population of New Zealand snapper (Pagrus auratus)

If such low Ne/N ratios are commonplace in marine species, many exploited marine fish stocks may be in danger of losing genetic variability, potentially resulting in reduced adaptability, population persistence, and productivity.
SPECIATION IN ANCIENT CRYPTIC SPECIES COMPLEXES: EVIDENCE FROM THE MOLECULAR PHYLOGENY OF BRACHIONUS PLICATILIS (ROTIFERA)
- A. Gómez, M. Serra, G. Carvalho, D. Lunt
- Biology, Environmental ScienceEvolution; international journal of organic…
- 1 July 2002
Analysis of rotifer resting eggs from 27 salt lakes in the Iberian Peninsula plus lakes from four continents revealed nine genetically divergent lineages, and sequence divergence estimates indicate that the B. plicatilis complex began diversifying many millions of years ago, yet has showed relatively high levels of morphological stasis.
Age of cichlids: new dates for ancient lake fish radiations.

- 1 May 2007
Accumulation of genetic diversity within the radiating lineages of the African Lakes Malawi, Victoria and Barombi Mbo, and Palaeolake Makgadikgadi began around or after the time of lake basin formation, suggesting lakes may have captured preexisting cichlid diversity from multiple sources from which adaptive radiations have evolved.

Ultrasequencing of the meiofaunal biosphere: practice, pitfalls and promises
- S. Creer, V. Fonseca, W. Thomas
- Environmental Science, BiologyMolecular Ecology
- 1 March 2010
An overview of meiofaunal metagenetic analyses, ranging from sample preservation and DNA extraction to PCR, sequencing and the bioinformatic interrogation of multiple, independent samples using 454 Roche sequencing platforms, is provided.
Genomic signatures of local directional selection in a high gene flow marine organism; the Atlantic cod (Gadus morhua)
- E. Nielsen, J. Hemmer-Hansen, G. Carvalho
- Biology, Environmental ScienceBMC Evolutionary Biology
- 1 December 2009
Findings illustrate that adaptive population divergence may indeed be prevalent despite seemingly high levels of gene flow, as found in most marine fishes and have important implications for the understanding of the interplay of evolutionary forces in general, and for the conservation of marine biodiversity under rapidly increasing evolutionary pressure from climate and fisheries induced changes in local environments.
Power for detecting genetic divergence: differences between statistical methods and marker loci
- N. Ryman, S. Palm, D. Ruzzante
- BiologyMolecular Ecology
- 1 July 2006
Computer simulations are used to assess and evaluate power when testing for genetic differentiation at multiple loci through combining test statistics or P values obtained by four different statistical approaches, viz.
Molecular genetics and the stock concept in fisheries
- G. Carvalho, L. Hauser
- Environmental ScienceReviews in Fish Biology and Fisheries
- 1 September 1994
The stock concept was linked strongly, at least in theory, with the desire to balance the impacts of harvesting with efforts to ensure continued economic returns, but how to actually recognize a stock was much more difficult to achieve than the theory.
