| Summary: | The extent of species' geographical distribution can help us define their sensitivity to environmental challenges. Rare species are expected to have narrower tolerance windows and reduced plasticity compared to their common relatives. Assessing rare species' tolerance and plasticity under environmental changes will thus help predicting future changes in the structure and functions of ecosystems. We examined the level of tolerance and transgenerational responses of life-history and physiological traits in a rare (Ophryotrocha robusta) and common (Ophryptrocha japonica) marine polychaete species exposed over two generations to ocean acidification (OA: pH -0.5) and warming (OW: + 4 °C) in isolation and combined (OAW: + 4 °C, pH -0.5). Life history traits (growth, fecundity and eggs volume) were measured on a four months period, after which metabolomics profiles were analysed to highlight molecular pattern (energetic metabolism) linked to life history traits' changes. In the rare species, warming scenarios (OW ... |
