From the Mountains to the Sea: Comparative Genomics of Mechanisms Underlying the Physiological Response to Low Oxygen
Tuesday, January 28, 12 PM, AHF 153 (Torrey Webb Room)
Abstract: Environmental variables can exert a considerable selective pressure across the entire organism – from their genome to their physiology. Organisms living in extreme environmental conditions provide excellent systems to investigate numerous basic questions about the limits of an organism's ability to adapt, to understanding the inherent repeatability of molecular adaptation, and thus the origins of biodiversity, by examining both phenotypic and genotypic novelty. My work uses both integrative and comparative approaches to understand the mechanisms underpinning the response to such environmental variables, with a focus on oxygen availability (i.e. hypoxia). This talk will journey through my previous work on high-altitude adaptation in Andean duck species, to my current work on hypoxia in copepods (and other crustaceans), and conclude with how my discoveries opened up numerous exciting avenues for future work in aquatic invertebrates.
