Impact of Ocean Acidification on Arctic invertebrates (Collaboration with Dr. Howard Browman at Institute of Marine Research in Norway)
The objective of this study is to study the effects of OA on marine cladocerans. The effects of temporal and spatial variations in multiple OA drivers (e.g. pCO2, salinity and temperature) on the physiology, transcriptomic and epigenetic changes will be investigated. Marine cladocerans (Podon spp. and/or Evadne spp.) will be used as a model to investigate the relative roles of genetic and epigenetic mechanisms in determining the adaptation capacity of marine populations to CO2 and temperature. Cladocerans are widely used as models to study the evolutionary basis of phenotypic plasticity because they reproduce clonally (asexually) and sexually, which offers a unique opportunity to assess the relative contributions of the epigenetic (in clonal populations) and genetic (in sexually reproducing populations) mechanisms underlying adaption to environmental drivers, and their molecular basis.
