Recurrent climate-induced mass-mortalities have been recorded in the Mediterranean Sea over the past 15 years. Cladocora caespitosa, the sole zooxanthellate scleractinian reef-builder in the Mediterranean, is among the organisms affected by these episodes. Extensive bioconstructions of this endemic coral are very rare at the present time and are threatened(More)
In the current global climate change scenario, stressors overlap in space and time, and knowledge on the effects of their interaction is highly needed to understand and predict the response and resilience of organisms. Corals, among many other benthic organisms, are affected by an increasing number of global change-related stressors including warming and(More)
The invasive algae Lophocladia lallemandii and Caulerpa racemosa are becoming an important threat to benthic assemblages in the Mediterranean Sea. Both species were first detected in Illa Grossa Bay (Columbretes Islands Marine Reserve, NW Mediterranean) in 2006, and their invasion was monitored until 2012. L. lallemandii showed a rapid outburst, spreading(More)
Long-lived species are characterized by low recruitment and mortality. In these species, longevity buffers low recruitment, but when catastrophic disturbances alter mortality, recruitment becomes critical for population recovery. In this study, we assessed basic biological traits—recruitment, post-settlement growth, and the mortality of juvenile corals—and(More)
Nodular morphology is typical of free-living coralline algae (Rhodophyta), which form extensive rhodolith beds worldwide over broad latitudinal and depth ranges (Foster 2001). Strikingly, under certain environmental conditions, coral coloniesmay also be able to live unattached to the substratum, as has been reported in the Atlantic, Indian and Pacific(More)
Cladocora caespitosa is the only reef-forming zooxanthellate scleractinian in the Mediterranean Sea. This endemic coral has suffered severe mortality events at different Mediterranean sites owing to anomalous summer heat waves related to global climate change. In this study, we assessed genetic structure and gene flow among four populations of this species(More)
Overexploitation leads to the ecological extinction of many oceanic species. The depletion of historical abundances of large animals, such as whales and sea turtles, is well known. However, the magnitude of the historical overfishing of exploited invertebrates is unclear. The lack of rigorous baseline data limits the implementation of efficient management(More)
Cladocora caespitosa is a reef-building zooxanthellate scleractinian coral in the Mediterranean Sea. Mortality events have recurrently affected this species during the last decade. Thus, knowledge of its genetic structure, population diversity, and connectivity is needed to accomplish suitable conservation plans. In order to obtain a better understanding of(More)
Cladocora caespitosa is a colonial and symbiotic scleractinian coral endemic to the Mediterranean Sea, which is threatened by disturbances related to global change. To assess its recovery capacity from physically induced tissue injuries, one to three polyps from 46 colonies were collected at 15 m depth in the Columbretes Islands Marine Reserve (NW(More)
Diseases of coralline algae, first reported in the 1990s in the Pacific (Littler and Littler 1995), have recently been reported associatedwith high seawater temperature in several localities in the Caribbean (Quéré et al. 2015). Here, we report the first record of coralline algal diseases similar to the previously described corallinewhite band syndrome(More)
