- The ESS under spatial variation with applications to sex allocationS R Proulx
Department of Biology, University of Utah, Salt Lake City, Utah 84112, USA
Theor Popul Biol 58:33-47. 2000..These results are compared with results from exact matrix models and computer simulations, all of which show strong congruence...
- Allelic divergence precedes and promotes gene duplicationStephen R Proulx
Center for Ecology and Evolutionary Biology, 5289 University of Oregon, Eugene, Oregon 97403, USA
Evolution 60:881-92. 2006..Thus, a solution to the paradox of the origin of organismal complexity via the expansion of gene families exists in the form of the deterministic spread of novel duplicates via natural selection...
- Can behavioural constraints alter the stability of signalling equilibria?S R Proulx
Department of Biology, 1210 University of Oregon, Eugene, OR 97403 1210, USA
Proc Biol Sci 268:2307-13. 2001..An example of signalling between mates is presented in order to demonstrate this equilibrium...
- Female choice via indicator traits easily evolves in the face of recombination and migrationS R Proulx
Department of Biology, University of Utah, Salt Lake City 84112, USA
Evolution 55:2401-11. 2001..Female choice reaches the highest levels for intermediate levels of heterogeneity, because at such levels of heterogeneity there is both a high risk and high cost of mismating...
- Older males signal more reliablyStephen R Proulx
Department of Zoology, University of Toronto, 25 Harbord Street, Toronto, ON, M5S 3G5, Canada
Proc Biol Sci 269:2291-9. 2002..This provides a novel rationale for female preference for older mates; older males reveal more information in their sexual displays...
- Does sex age you?Stephen R Proulx
Center for Ecology and Evolutionary Biology, University of Oregon, Eugene, OR 97403, USA
Sci Aging Knowledge Environ 2004:pe14. 2004..If females cannot find and maintain mating pairs for long enough to replace themselves, the population will become extinct. This puts a lower limit on the levels of longevity that will be observed in nature...
- The opportunity for canalization and the evolution of genetic networksStephen R Proulx
Center for Ecology and Evolutionary Biology, University of Oregon, Eugene, Oregon 97403 5289, USA
Am Nat 165:147-62. 2005..Because load induced through migration, segregation, developmental noise, and environmental variance is not mutation limited, each can cause strong selection for canalization...
- Sources of stochasticity in models of sex allocation in spatially structured populationsS R Proulx
Center for Ecology and Evolutionary Biology, University of Oregon, Eugene, OR 97403 2364, USA
J Evol Biol 17:924-30. 2004..This allows the evolution of either female- or male-biased sex ratios depending on which sexual function is more variable...
- Quasi-species evolution in subdivided populations favours maximally deleterious mutationsBrendan D O'Fallon
Department of Biology, University of Utah, 257 South 1400 East, Salt Lake City, UT 84112, USA
Proc Biol Sci 274:3159-64. 2007..Our results indicate that RNA viruses that produce acute infections initiated by a small number of virions are expected to evolve fragile genetic architectures when compared with other RNA viruses...
- Rules of nonallelic noncomplementation at the synapse in Caenorhabditis elegansK J Yook
Department of Biology, University of Utah, 257 S. 1400 East, Salt Lake City, UT 84112-0840, USA
Genetics 158:209-20. 2001..Thus, this genetic interaction is specific for genes acting in the same pathway, that is, for genes acting in synaptic vesicle trafficking...
- The role of life cycle and migration in selection for variance in offspring numberMax Shpak
Department of Biological Sciences, University of Texas at El Paso, El Paso, TX 79968, USA
Bull Math Biol 69:837-60. 2007..These results are found to be qualitatively consistent with the individual-based simulation results in Shpak [Theor. Biosci.124:65-85, 2005]...
- A general theory for the evolutionary dynamics of virulenceTroy Day
Department of Mathematics, Queen s University, Kingston, Ontario, K7L 3N6, Canada
Am Nat 163:E40-63. 2004..It also leads to novel predictions that are not possible using the game-theoretic approach. The general theory can be used to model the evolution of other pathogen traits as well...
