Garrabou, Joaquim Conserve and sustainably use the oceans, seas and marine resources for sustainable development ASLO Aquatic Sciences Meeting, Resilience and Recovery in Aquatic Systems, 4-9 June 2023, Palma de Mallorca, Spain Recurrent mass mortality events (MMEs) linked to marine heatwaves (MHWs) have been affecting Mediterranean coralligenous habitats. Combining field surveys with experiments in controlled conditions allowed to characterize spatial variability in responses to thermal stress among species, populations and individuals. However, the temporal variability in this response remains poorly known. Thus, we replicated common garden experiments (control vs. thermal stress) during three consecutive years (2015-2017) using the same individuals from three populations of the habitat-forming octocoral Paramuricea clavata. We found that the average percentage of tissue necrosis per population during the experiment significantly variated across years. This result was due to the decrease in the probability of survival in 2017 when a severe MHWs was observed in the study area. Furthermore, we genotyped all individuals with 14 microsatellites to define the genetic framework of the study and found that populations were genetically differentiated, but their respective levels of genetic isolation were similar and not related to mean tissue necrosis. At individual level, we tested for the occurrence of heterosis. Overall, our data characterize in detail the temporal variability in the response to thermal stress showing that this response may: i) critically driven by summer conditions and ii) under stronger influence of environmental factors compared to genetics. These results unambiguously question the potential adaptation of P. clavata to on-going warming trend Peer reviewed 2024-04-19T09:02:15Z 2024-04-19T09:02:15Z 2023-06-07 comunicación de congreso ASLO Aquatic Sciences Meeting (2023) http://hdl.handle.net/10261/354352 en Sí none Association for the Sciences of Limnology and Oceanography |
