Groups of sympatric taxa with low inter-specific genetic differentiation,
but considerable ecological differences, offer great opportunities to
study the dynamics of divergence and speciation. This is the case of
ciscoes (Coregonus spp.) in the Laurentian Great Lakes, which are
characterized by a complex evolutionary history and are commonly described
as having undergone an adaptive radiation. In this study, morphometrics,
stable isotopes and transcriptome sequencing were used to study the
relationships within the Coregonus artedi complex in western Lake
Superior. We observed general concordance for morphological, ecological
and genomic variation, but the latter was more taxonomically informative
as it showed less overlap among species in multivariate space. Low levels
of genetic differentiation were observed between individuals
morphologically identified as C. hoyi and C. zenithicus, which could be
evidence of incomplete lineage sorting or recent hybridization between the
two groups. Transcriptome-based single nucleotide polymorphisms exhibited
significant divergence for genes associated with vision, development,
metabolism and immunity among species that occupy different habitats. This
study highlights the importance of using an integrative approach when
studying groups of taxa with a complex evolutionary history, as
individual-level analyses of multiple independent datasets can provide a
clearer picture of the patterns and processes associated with the origins
of biodiversity.
These data were collected and processed as described in the associated
manuscript.
