Hollie Putnam


I am broadly interested in physiological ecology of marine invertebrates. I strive to understand how the immediate abiotic environment and biotic interactions drive organism phenotype and ecological and evolutionary processes. To date, I have primarily utilized scleractinian, or reef-building corals, and other calcifying marine invertebrates, such as shellfish, as my study systems. These organisms are ecosystem engineers that shape important fisheries and are ideal systems in which to focus on biological response within the context of local environmental stress and a changing climate. There is enormous variability in the way organisms respond to environmental perturbations resulting in differential survival of species. I study the mechanisms underlying this variability including innovations related to genetic adaptation, rapid acclimatization through epigenetic mechanisms and phenotypic plasticity, parental effects, and shifts in the dynamic associated microorganism assemblages (i.e., the microbiome). My research crosses differrent levels of biological complexity including gene, protein, metabolite, and organismal response to identify how these levels interact to drive phenotypic consequences and ecological patterning.

I practice reproducible and open science and work in a very collaborative frame. For more information please visit my lab website at www.hollieputnam.com
