Project Description
One important part of climate change is ocean acidification (OA) caused by the increase of atmospheric CO2 1, that once dissolved in seawater leads to carbonic acid, which then releases hydrogen ions, lowering the water pH2. Since the industrial revolution, the pH has dropped from 8.2 to 8.07 and should reach 7.7 by the year 21001 with increased fluctuations of pH during the day3. Past research focused mainly on the impact of lower pH on calcifying species and mineralization processes. However, few studies have investigated the impact of OA on chemical communication, which directly affect the survival of species (detection of prey/predator, mating partner), causing changes in the marine food webs, marine communities (see figure below, made by VM). The systematic study of a globally distributed non-calcifying model species combining chemical analyses, comparative transcriptomics, genetics, CRISPR-Cas9-mediated gene knockout experiments should help to better predict how OA impacts the marine communities by modifying their chemical communication, whether acclimation and adaptation occur and at which costs.

Effects of Environmental Context on Species Trait Expression in Moderating Projections of Marine Ecosystems Futures Jan 1, 2020 - Dec 31, 2023
Recent syntheses have emphasized the importance of functional traits, rather than species diversity per se, for maintaining ecosystem functioning and service delivery, and provide impetus to develop functional trait approaches that assess the contrib...
