Extreme positive selection on a new highly-expressed larval glycoprotein (LGP) gene in Galaxias fishes (Osmeriformes: Galaxiidae)Lise J Wallis
Department of Zoology, University of Otago, Dunedin, New Zealand
Mol Biol Evol 28:399-406. 2011..We postulate that the strong Darwinian evolution exhibited by this protein may reflect some type of immunoprotection at this vulnerable larval stage...
New Zealand phylogeography: evolution on a small continentGraham P Wallis
Department of Zoology, University of Otago, Dunedin 9054, New Zealand
Mol Ecol 18:3548-80. 2009..Intriguingly, then, origins of the flora and fauna are island-like, whereas phylogeographic structure often reflects continental geological processes...
Onset of glaciation drove simultaneous vicariant isolation of Alpine insects in New ZealandGraham A McCulloch
Department of Zoology, University of Otago, PO Box 56, Dunedin, New Zealand
Evolution 64:2033-43. 2010..This study thus indicates an important cladogenetic role for glaciation, an abiotic evolutionary process that is more typically associated with loss of biodiversity...
Do insects lose flight before they lose their wings? Population genetic structure in subalpine stonefliesGraham A McCulloch
Department of Zoology, University of Otago, Dunedin, New Zealand
Mol Ecol 18:4073-87. 2009..This finding implies that Zelandoperla flight loss occurs independently of wing loss, and might reflect underlying flight muscle reduction...
Gene trees versus species trees: reassessing life-history evolution in a freshwater fish radiationJonathan M Waters
Department of Zoology, University of Otago, PO Box 56, Dunedin 9054, New Zealand
Syst Biol 59:504-17. 2010..We discuss factors that might explain the apparently misleading phylogenetic inferences generated by mtDNA...
Geological dates and molecular rates: rapid divergence of rivers and their biotasJonathan M Waters
Department of Zoology, University of Otago, PO Box 56, Dunedin, New Zealand
Syst Biol 56:271-82. 2007..We recommend that--wherever possible--biologists should start to reassess the conclusions of such studies by using more appropriate molecular calibrations derived from recent geological events...
Heterozygosity-fitness correlations and their relevance to studies on inbreeding depression in threatened speciesCatherine E Grueber
Department of Zoology, University of Otago, PO Box 56, Dunedin, New Zealand
Mol Ecol 17:3978-84. 2008..The study of HFCs in outbred populations is of interest in itself, but the results may not translate directly to threatened populations that have undergone severe bottlenecks...
A comparison of five hybrid zones of the weta Hemideina thoracica (Orthoptera: Anostostomatidae): degree of cytogenetic differentiation fails to predict zone widthMary Morgan-Richards
Department of Zoology, University of Otago, P O Box 56, Dunedin, New Zealand
Evolution 57:849-61. 2003..It appears that, even within a single species, the extent of karyotypic differentiation between pairs of races is not a good predictor of the level of disadvantage suffered by hybrids...
Inbreeding and endangered species management: is New Zealand out of step with the rest of the world?Ian G Jamieson
Department of Zoology, University of Otago, P O Pox 56, Dunedin, New Zealand
Conserv Biol 20:38-47. 2006..g., preventing reinvasion of islands by mammalian predators) will continue to receive high priority in New Zealand because of their much larger impacts, we advocate that genetic considerations be better integrated into recovery plans...
Phylogenetic placement of retropinnid fishes: data set incongruence can be reduced by using asymmetric character state transformation costsJonathan M Waters
Department of Zoology, University of Otago, Dunedin, New Zealand
Syst Biol 51:432-49. 2002..We discuss the antitropical biogeography of osmeroid fishes in the context of vicariance and transequatorial dispersal...
