The influence of gene-environment interactions on GHR and IGF-1 expression and their association with growth in brook charr, Salvelinus fontinalis(Mitchill) (2007)

Côté, Guillaume, Perry, Guy, Blier, Pierre, Bernatchez, Louis

Abstract Background Quantitative reaction norm theory proposes that genotype-by-environment interaction (GxE) results from inter-individual differences of expression in adaptive suites of genes in...

MHC Adaptive Divergence between Closely Related and Sympatric African Cichlids (2007)

Blais, Jonatan, Rico, Ciro, Van Oosterhout, Cock, Cable, Joanne, Turner, George F., Bernatchez, Louis

[Background] The haplochromine cichlid species assemblages of Lake Malawi and Victoria represent some of the most important study systems in evolutionary biology. Identifying adaptive divergence...

MHC Adaptive Divergence between Closely Related and Sympatric African Cichlids (2007)

Blais, Jonatan, Rico, Ciro, Van Oosterhout, Cock, Cable, Joanne, Turner, George F., Bernatchez, Louis

ADAPTIVE MIGRATORY DIVERGENCE AMONG SYMPATRIC BROOK CHARR POPULATIONS (2005)

Dylan J. Fraser, Louis Bernatchez

Ecological processes clearly contribute to population divergence, yet how they interact over complex life cycles remains poorly understood. Notably, the evolutionary consequences of migration between...

NONLINEAR EFFECTS OF FEMALE MATE CHOICE IN WILD THREESPINE STICKLEBACKS (2004)

Jonatan Blais, Ciro Rico, Louis Bernatchez

Sexual selection by mate choice represents a very important selective pressure in many animal species and might have evolutionary impacts beyond exaggeration of secondary sexual traits. Describing...

SHIFTING PATTERNS IN GENETIC CONTROL AT THE EMBRYO-ALEVIN BOUNDARY IN BROOK CHARR (2004)

Céline Audet, Benjamin Laplatte, Louis Bernatchez

Maternal inputs to offspring early in development are initially high but the process of development suggests that ontogenetic shifts in the importance of maternal genetic variation relative to other...

DIFFERENTIAL REPRODUCTIVE SUCCESS AND HERITABILITY OF ALTERNATIVE REPRODUCTIVE TACTICS IN WILD ATLANTIC SALMON (SALMO SALAR L) (2003)

Dany Garant, Julian J. Dodson, Louis Bernatchez

A critical step in understanding the evolution and maintenance of alternative reproductive tactics is to obtain accurate comparisons of their fitness and to determine factors influencing individual...

Decline of North Atlantic eels: a fatal synergy? (2003)

Wirth,Thierry, Bernatchez,Louis

Panmictic species pose particular problems for conservation because their welfare can be addressed effectively only on a global scale. We recently documented by means of microsatellite analysis that...

GENETICALLY BASED PHENOTYPE-ENVIRONMENT ASSOCIATION FOR SWIMMING BEHAVIOR IN LAKE WHITEFISH ECOTYPES (COREGONUS CLUPEAFORMIS MITCHILL) (2002)

Sean M. Rogers, V. Gagnon, Louis Bernatchez

Studies of phenotype-environment associations in adaptive radiation have focused largely on morphological traits related to resource-based phenotypic differences. The genetic basis of adaptive...

CLINAL VARIATION AT MICROSATELLITE LOCI REVEALS HISTORICAL SECONDARY INTERGRADATION BETWEEN GLACIAL RACES OF COREGONUS ARTEDI (TELEOSTEI: COREGONINAE) (2001)

Julie Turgeon, Louis Bernatchez

Classical models of the spatial structure of population genetics rely on the assumption of migration-drift equilibrium, which is seldom met in natural populations having only recently colonized their...

LANDSCAPE STRUCTURE AND HIERARCHICAL GENETIC DIVERSITY IN THE BROOK CHARR, SALVELINUS FONTINALIS (2001)

Vincent Castric, Forrest Bonney, Louis Bernatchez

Explaining the extent, causes, and consequences of biotic distributions in space is fundamental to our understanding of how species evolve and cope with particular environments. Yet, identifying...

HOLARCTIC PHYLOGEOGRAPHY OF ARCTIC CHARR (SALVELINUS ALPINUS L.) INFERRED FROM MITOCHONDRIAL DNA SEQUENCES (2001)

Patrick C. Brunner, Marlis R. Douglas, Alexander Osinov, Chris C. Wilson, Louis Bernatchez

This study evaluated mitochondrial DNA (mtDNA) sequence variation in a 552-bp fragment of the control region of Arctic charr (Salvelinus alpinus) by analyzing 159 individuals from 83 populations...

THE EVOLUTIONARY HISTORY OF BROWN TROUT (SALMO TRUTTA L.) INFERRED FROM PHYLOGEOGRAPHIC, NESTED CLADE, AND MISMATCH ANALYSES OF MITOCHONDRIAL DNA VARIATION (2001)

Louis Bernatchez

Phylogeographic, nested clade, and mismatch analyses of mitochondrial DNA (mtDNA) variation were used to infer the temporal dynamics of distributional and demographic history of brown trout (Salmo...

The rise and fall of isolation by distance in the anadromous brook charr (Salvelinus fontinalis Mitchill).

Castric, Vincent, Bernatchez, Louis

Geographic patterns of genetic diversity depend on a species' demographic properties in a given habitat, which may change over time. The rates at which patterns of diversity respond to changes in...

Surviving with low genetic diversity: the case of albatrosses

Milot, Emmanuel, Weimerskirch, Henri, Duchesne, Pierre, Bernatchez, Louis

Low genetic diversity is predicted to negatively impact species viability and has been a central concern for conservation. In contrast, the possibility that some species may thrive in spite of a...

The Phenomics and Expression Quantitative Trait Locus Mapping of Brain Transcriptomes Regulating Adaptive Divergence in Lake Whitefish Species Pairs (Coregonus sp.)

Whiteley, Andrew R., Derome, Nicolas, Rogers, Sean M., St-Cyr, Jérôme, Laroche, Jérôme, Labbe, Aurélie, ...

We used microarrays and a previously established linkage map to localize the genetic determinants of brain gene expression for a backcross family of lake whitefish species pairs (Coregonus sp.). Our...
