Reduced sperm performance in backcross hybrids between species pairs of whitefish (Coregonus clupeaformis)
Previous work has demonstrated that genomic incompatibilities work together with ecologically divergent selection to promote and maintain reproductive isolation between incipient species (dwarf and normal) of lake whitefish (Coregonus clupeaformis (Mitchill, 1818)). Whitefish spawn in groups with external fertilization, which creates conditions for strong sperm competition. In this study, we as...
متن کاملGenetic structure of lake whitefish (Coregonus clupeaformis) in Lake Michigan
Genetic relationships among lake whitefish (Coregonus clupeaformis) spawning aggregates in Lake Michigan were assessed and used to predict a stock or management unit (MU) model for the resource. We hypothesized that distinct spawning aggregates represented potential MUs and that differences at molecular markers underlie population differentiation. Genetic stock identification using 11 microsate...
متن کاملTyrannosaurs as long-lived species
Biodemographic analysis would be essential to understand population ecology and aging of tyrannosaurs. Here we address a methodology that quantifies tyrannosaur survival and mortality curves by utilizing modified stretched exponential survival functions. Our analysis clearly shows that mortality patterns for tyrannosaurs are seemingly analogous to those for 18th-century humans. This result sugg...
متن کاملBAC library construction, screening and clone sequencing of lake whitefish (Coregonus clupeaformis, Salmonidae) towards the elucidation of adaptive species divergence.
Genomic DNA sequences and other genomic resources are essential towards the elucidation of the genomic bases of adaptive divergence and reproductive isolation. Here, we describe the construction, characterization and screening of a nonarrayed BAC library for lake whitefish (Coregonus clupeaformis). We then show how the combined use of BAC library screening and next-generation sequencing can lea...
متن کاملRadiocarbon age-offsets in an arctic lake reveal the long-term response of permafrost carbon to climate change
Continued warming of the Arctic may cause permafrost to thaw and speed the decomposition of large stores of soil organic carbon (OC), thereby accentuating global warming. However, it is unclear if recent warming has raised the current rates of permafrost OC release to anomalous levels or to what extent soil carbon release is sensitive to climate forcing. Here we use a time series of radiocarbon...
