Maternal effects and the potential for evolution in a natural population of animalsAndrew G McAdam
Department of Biological Sciences, University of Alberta, Edmonton, Canada
Evolution 56:846-51. 2002..36) relative to that predicted by heritability alone. Simple heritabilities, therefore, may severely underestimate or overestimate the potential for evolution in natural populations of animals...
Variation in viability selection among cohorts of juvenile red squirrels (Tamiasciurus hudsonicus)Andrew G McAdam
Department of Biological Sciences, University of Alberta, Edmonton, Alberta T6G 2E9, Canada
Evolution 57:1689-97. 2003..As a result, predicting the occurrence of very strong episodes of selection will be extremely difficult, but predicting the microevolutionary responses to observed selection on individual cohorts remains feasible...
Anticipatory reproduction and population growth in seed predatorsStan Boutin
Department of Biological Sciences, University of Alberta, Edmonton, Alberta T6G 2E9, Canada
Science 314:1928-30. 2006....
Adopting kin enhances inclusive fitness in asocial red squirrelsJamieson C Gorrell
Department of Biological Sciences, University of Alberta, Edmonton, Alberta T6G 2E9, Canada
Nat Commun 1:22. 2010..By focusing on adoption in an asocial species, our study provides a clear test of Hamilton's rule that explains the persistence of occasional altruism in a natural mammal population...
Maternal effects and the response to selection in red squirrelsAndrew G McAdam
Department of Biological Sciences, University of Alberta, Edmonton, Alberta T6G 2E9, Canada
Proc Biol Sci 271:75-9. 2004....
Genetic and plastic responses of a northern mammal to climate changeDenis Reale
Department of Biology, McGill University, 1205 Docteur Penfield Avenue, Montreal, Quebec H3A 1B1, Canada
Proc Biol Sci 270:591-6. 2003..The timing of breeding in this population of squirrels, therefore, has advanced as a result of both phenotypic changes within generations, and genetic changes among generations in response to a rapidly changing environment...
Persistent maternal effects on juvenile survival in North American red squirrelsTricia D Kerr
Department of Natural Resource Sciences, Macdonald Campus, McGill University, Ste Anne de Bellevue, Quebec H9X 3V9, Canada
Biol Lett 3:289-91. 2007..However, supplemented mothers did provide their juveniles an early start by breeding an average of 18 days earlier than control mothers, which may explain the persistent survival advantages their juveniles experienced...
Self-recognition, color signals, and cycles of greenbeard mutualism and altruismBarry Sinervo
Department of Ecology and Evolutionary Biology, University of California, Earth and Marine Sciences Building, Santa Cruz, CA 95064, USA
Proc Natl Acad Sci U S A 103:7372-7. 2006..Such cycles provide a mechanism encouraging the origin and stability of true altruism...
Cohort effects in red squirrels: the influence of density, food abundance and temperature on future survival and reproductive successSébastien Descamps
Centre d Etudes Nordiques, Universite du Quebec a Rimouski, 300 Allee des Ursulines, Rimouski, Quebec G5L 3A1, Canada
J Anim Ecol 77:305-14. 2008..6. The general importance of silver-spoon effects for adult demographic performance might therefore be underestimated, and taking adult environment into account appears to be necessary when studying long-term cohort effects...
Maturational costs of reproduction due to clutch size and ontogenetic conflict as revealed in the invisible fractionBarry Sinervo
Department of Ecology and Evolutionary Biology, University of California, Santa Cruz, CA 95064, USA
Proc Biol Sci 275:629-38. 2008..Such episodes of selection prior to phenotypic expression of the trait will have important consequences for the evolution of reproductive investment...
