Willett C. Hybrid breakdown weakens under thermal stress in population crosses of the copepod Tigriopus californicus. J Hered. 2012;103:103-14 pubmed publisher
..These results suggest that high temperature stress could either increase the positive impacts of hybridization or decrease the negative impacts of hybridization resulting in lowered hybrid breakdown in these population crosses. ..
Willett C. Gene conversion yields novel gene combinations in paralogs of GOT1 in the copepod Tigriopus californicus. BMC Evol Biol. 2013;13:148 pubmed publisher
..The evolutionary patterns across these paralogs show how gene conversion can both constrain and facilitate diversification of genetic sequences. ..
Willett C. Complex deleterious interactions associated with malic enzyme may contribute to reproductive isolation in the copepod Tigriopus californicus. PLoS ONE. 2011;6:e21177 pubmed publisher
..Confirmation of this idea will require more fine-scale mapping of the interactions of the ME2 region of the genome. ..
Willett C. Quantifying the elevation of mitochondrial DNA evolutionary substitution rates over nuclear rates in the intertidal copepod Tigriopus californicus. J Mol Evol. 2012;74:310-8 pubmed publisher
..The results from this study suggest that mtDNA is evolving at a very rapid rate in this copepod species, and this could increase the likelihood that mtDNA evolution is involved in the generation of reproductive isolation...
Willett C, Ladner J. Investigations of fine-scale phylogeography in Tigriopus californicus reveal historical patterns of population divergence. BMC Evol Biol. 2009;9:139 pubmed publisher
