ENVIRONMENTAL CORRELATES OF POPULATION DIFFERENTIATION IN ATLANTIC HERRING (2005)

Dorte Bekkevold, Carl André, Thomas G. Dahlgren, Else Torstensen, Henrik Mosegaard, ...

The marine environment is characterized by few physical barriers, and pelagic fishes commonly show high migratory potential and low, albeit in some cases statistically significant, levels of genetic...

SPECIATION IN ANCIENT CRYPTIC SPECIES COMPLEXES: EVIDENCE FROM THE MOLECULAR PHYLOGENY OF BRACHIONUS PLICATILIS (ROTIFERA) (2002)

Africa Gómez, Manuel Serra, Gary R. Carvalho, David H. Lunt

Continental lake-dwelling zooplanktonic organisms have long been considered cosmopolitan species with little geographic variation in spite of the isolation of their habitats. Evidence of...

Loss of microsatellite diversity and low effective population size in an overexploited population of New Zealand snapper (Pagrus auratus)

Hauser, Lorenz, Adcock, Greg J., Smith, Peter J., Bernal Ramírez, Julio H., Carvalho, Gary R.

Although the effects of overfishing on species diversity and abundance are well documented, threats to the genetic diversity of marine fish populations have so far been largely neglected. Indeed,...

Reconstruction of microsatellite mutation history reveals a strong and consistent deletion bias in invasive clonal snails, Potamopyrgus antipodarum.

Weetman, David, Hauser, Lorenz, Carvalho, Gary R

Direct observations of mutations and comparative analyses suggest that nuclear microsatellites show a tendency to expand, with reports of deletion biases limited to very long alleles or a few loci in...

Temporal analysis of archived samples indicates marked genetic changes in declining North Sea cod (Gadus morhua).

Hutchinson, William F, Van Oosterhout, Cock, Rogers, Stuart I, Carvalho, Gary R

Despite increasing evidence that current exploitation rates can contribute to shifts in life-history traits and the collapse of marine fish stocks, few empirical studies have investigated the likely...

Biocomplexity in a highly migratory pelagic marine fish, Atlantic herring

Ruzzante, Daniel E, Mariani, Stefano, Bekkevold, Dorte, André, Carl, Mosegaard, Henrik, Clausen, Lotte A.W, ...

The existence of biologically differentiated populations has been credited with a major role in conferring sustainability and in buffering overall productivity of anadromous fish population complexes...

Mating trials validate the use of DNA barcoding to reveal cryptic speciation of a marine bryozoan taxon

Gómez, Africa, Wright, Peter J, Lunt, David H, Cancino, Juan M, Carvalho, Gary R, Hughes, Roger N

Despite increasing threats to the marine environment, only a fraction of the biodiversity of the oceans has been described, owing in part to the widespread occurrence of cryptic species. DNA-based...

Paradoxical polyembryony? Embryonic cloning in an ancient order of marine bryozoans

Hughes, Roger N, D'Amato, M. Eugenia, Bishop, John D.D, Carvalho, Gary R, Craig, Sean F, Hansson, Lars J, ...

Prolific polyembryony is reported in few major taxa, but its occurrence has generated theoretical debate on potential conflict between sexual and asexual reproduction. It is, therefore, important to...

Evolution of a cichlid fish in a Lake Malawi satellite lake

Genner, Martin J, Nichols, Paul, Carvalho, Gary R, Robinson, Rosanna L, Shaw, Paul W, Smith, Alan, ...

Allopatric divergence in peripheral habitats may lead to rapid evolution of populations with novel phenotypes. In this study we provide the first evidence that isolation in peripheral habitats may...
