A roadmap for understanding the evolutionary significance of structural genomic variation

C Mérot, RA Oomen, A Tigano… - Trends in Ecology & …, 2020 - cell.com
Structural genomic variants (SVs) are ubiquitous and play a major role in adaptation and
speciation. Yet, comparative and population genomics have focused predominantly on gene …

Locally adaptive inversions modulate genetic variation at different geographic scales in a seaweed fly

C Mérot, EL Berdan, H Cayuela… - Molecular biology …, 2021 - academic.oup.com
Across a species range, multiple sources of environmental heterogeneity, at both small and
large scales, create complex landscapes of selection, which may challenge adaptation, …

[HTML][HTML] Balancing selection via life-history trade-offs maintains an inversion polymorphism in a seaweed fly

C Mérot, V Llaurens, E Normandeau… - Nature …, 2020 - nature.com
How natural diversity is maintained is an evolutionary puzzle. Genetic variation can be eroded
by drift and directional selection but some polymorphisms persist for long time periods, …

Copy number variants outperform SNPs to reveal genotype–temperature association in a marine species

…, M Laporte, Q Rougemont, C Mérot… - Molecular …, 2020 - Wiley Online Library
Copy number variants (CNVs) are a major component of genotypic and phenotypic variation
in genomes. To date, our knowledge of genotypic variation and evolution has largely been …

[HTML][HTML] Selective sweeps on novel and introgressed variation shape mimicry loci in a butterfly adaptive radiation

…, SH Martin, SL Barker, GRP Moreira, C Mérot… - PLoS …, 2020 - journals.plos.org
Natural selection leaves distinct signatures in the genome that can reveal the targets and
history of adaptive evolution. By analysing high-coverage genome sequence data from 4 major …

[PDF][PDF] Going beyond SNPs: The role of structural genomic variants in adaptive evolution and species diversification

M Wellenreuther, C Mérot, E Berdan… - Molecular ecology, 2019 - bio.ulaval.ca
Although single‐nucleotide polymorphism (SNPs) were initially thought to make‐up the majority
of selectable variation (Morin, Luikart, & Wayne, 2004; Sachidanandam et al., 2001), it is …

Beyond magic traits: Multimodal mating cues in Heliconius butterflies

C Mérot, B Frérot, E Leppik, M Joron - Evolution, 2015 - academic.oup.com
Species coexistence involves the evolution of reproductive barriers opposing gene flow.
Heliconius butterflies display colorful patterns affecting mate choice and survival through …

What shapes the continuum of reproductive isolation? Lessons from Heliconius butterflies

C Mérot, C Salazar, RM Merrill… - Proceedings of the …, 2017 - royalsocietypublishing.org
The process by which species evolve can be illuminated by investigating barriers that limit
gene flow between taxa. Recent radiations, such as Heliconius butterflies, offer the …

Structural variants and speciation: multiple processes at play

…, M Joron, JB Searle, C Mérot - Cold Spring …, 2024 - cshperspectives.cshlp.org
Research on the genomic architecture of speciation has increasingly revealed the importance
of structural variants (SVs) that affect the presence, abundance, position, and/or direction …

Comparing environmental metabarcoding and trawling survey of demersal fish communities in the Gulf of St. Lawrence, Canada

SF Afzali, H Bourdages, M Laporte, C Mérot… - Environmental …, 2021 - Wiley Online Library
Biodiversity assessment is an important part of conservation management that ideally can
be accomplished with noninvasive methods without influencing the structure and functioning …
