On the Origin and Trigger of the Notothenioid Adaptive Radiation [PDF]
PLoS ONE, 2011 Adaptive radiation is usually triggered by ecological opportunity, arising through (i) the colonization of a new habitat by its progenitor; (ii) the extinction of competitors; or (iii) the emergence of an evolutionary key innovation in the ancestral ...

Multiple Pathways of Visual Adaptations for Water Column Usage in an Antarctic Adaptive Radiation [PDF]
Ecology and EvolutionEvolutionary transitions in water column usage have played a major role in shaping ray‐finned fish diversity. However, the extent to which vision‐associated trait complexity and water column usage is coupled remains unclear.

Genomics of cold adaptations in the Antarctic notothenioid fish radiation [PDF]
Nature Communications, 2023 Numerous novel adaptations characterise the radiation of notothenioids, the dominant fish group in the freezing seas of the Southern Ocean. To improve understanding of the evolution of this iconic fish group, here we generate and analyse new genome ...

Molecular Diet Analysis of Adélie Penguins (Pygoscelis adeliae) in the Ross Sea Using Fecal DNA [PDF]
Biology, 2022 The diet of Adélie penguins, Pygoscelis adeliae, is a useful indicator in understanding the ecological conditions of their habitats. The diets of Adélie penguins were studied using metabarcoding and quantitative PCR (qPCR) analyses of fecal DNA from ...

Intron turnover of slc26a1 and slc26a2 and convergence of intron insertion sites [PDF]
Scientific ReportsIntron gain and loss are rare events in vertebrates; however, comparative genome analysis of elephant sharks, tetrapods, and teleosts revealed a higher level of intron turnover in teleosts.

Temperature activated transient receptor potential ion channels from Antarctic fishes [PDF]
Open Biology, 2023 Antarctic notothenioid fishes (cryonotothenioids) live in waters that range between −1.86°C and an extreme maximum +4°C. Evidence suggests these fish sense temperature peripherally, but the molecular mechanism of temperature sensation in unknown ...

Population genomics of an icefish reveals mechanisms of glacier-driven adaptive radiation in Antarctic notothenioids [PDF]
BMC Biology, 2022 Background Antarctica harbors the bulk of the species diversity of the dominant teleost fish suborder—Notothenioidei. However, the forces that shape their evolution are still under debate.

Hardy-Weinberg Equilibrium Filtering in Population Genomics: Empirical Review and Decision Framework for Improved Practice. [PDF]
Ecol EvolHardy–Weinberg equilibrium (HWE) filtering is widely used in population genomics, but its application remains inconsistent and often lacks biological justification. This review went through recent empirical studies that demonstrate awareness of these issues to assess whether conceptual understanding has led to improved practice. This review synthesises
