Divergence in physiological factors affecting swimming performance between anadromous and resident populations of brook charr Salvelinus fontinalis.
In this study, an anadromous strain (L) and a freshwater-resident (R) strain of brook charr Salvelinus fontinalis as well as their reciprocal hybrids, were reared in a common environment and submitted to swimming tests combined with salinity challenges. The critical swimming speeds (Ucrit ) of the different crosses were measured in both fresh (FW) and salt water (SW) and the variations in sever...
متن کاملMajor disruption of gene expression in hybrids between young sympatric anadromous and resident populations of brook charr (Salvelinus fontinalis Mitchill).
Genome-wide analyses of the transcriptome have suggested that male-biased genes are the first targets of genomic incompatibilities (g.i.) in inter-specific hybrids. However, those studies have almost invariably focused on Drosophila species that diverged at least 0.9 Ma, and with sterile male hybrids. Here, we use microarrays to analyse patterns of gene expression in very closely related (diver...
متن کاملComparative transcriptomics of anadromous and resident brook charr Salvelinus fontinalis before their first salt water transition
Most salmonid taxa have an anadromous life history strategy, whereby fish migrate to saltwater habitats for a growth period before returning to freshwater habitats for spawning. Moreover, several species are characterized by different life history tactics whereby resident and anadromous forms may occur in genetically differentiated populations within a same species, as well as polymorphism with...
متن کاملThe effect of temperature and ammonia exposure on swimming performance of brook charr (Salvelinus fontinalis).
The effects of water temperature and ammonia concentration on swimming capacity of brook charr (Salvelinus fontinalis, Mitchill, 1814) were determined by measuring gait transition speed (U(gt), cms(-1)), maximum burst speed (U(max), cms(-1)), tail-beat amplitude (a, cm), tail-beat frequency (f, Hz), maximum acceleration of bursts (A(max), cms(-2)), number of bursts, distance of bursts (cm) and ...
متن کاملThe rise and fall of isolation by distance in the anadromous brook charr (Salvelinus fontinalis Mitchill).
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 demographic properties and approach equilibrium are therefore pivotal in our understanding of spatial patterns of diversity. The brook charr Salvelinus fontinalis is a coastal fish exhibiting limited m...
