The warming trend of the Mediterranean Sea is a long-term process. It has resulted in northwards and westwards range expansion abundance increase thermophilic species, both native non-indigenous, shrinking cold-affinity species. Marine heatwaves (MHWs) are relatively short-term extreme episodes that responsible for spectacular mortality events some species have been extensively reported literature. In contrast, benefit from MHWs (the ‘winners’) much less studied. A record-breaking MHW...
Arborescent macro-algae forests covering temperate rocky reefs are a known habitat for juvenile fishes. However, in the Mediterranean, these undergoing severe transformations due to pressures from global change. In our study, fish assemblages differed between pristine arborescent (Cystoseira brachycarpa var. balearica) versus an alternate state: bushland (Dictyotales - Sphacelariales). Forests hosted richer and three-fold more abundant assemblages. This was consistent through space, whatever...
In Mediterranean subtidal rocky reefs, Cystoseira spp. (Phaeophyceae) form dense canopies up to 1 m high. Such habitats, called 'Cystoseira forests', are regressing across the entire Sea due multiple anthropogenic stressors, as other large brown algae forests worldwide. being replaced by structurally less complex but little information is available regarding potential difference in structure and composition of fish assemblages between these habitats. To fill this void, we compared...
Abstract Coastal zones are ecosystems of high economic value but exposed to numerous disturbances, while they represent nurseries for many fish species, raising the issue preservation their functions and services. In this context, juvenile assemblages all types habitats present in shallow coastal were studied on south-east coast France using underwater visual censuses warm (June–July 2014) cold (April 2015) periods. A total fourteen habitat characterized, which could be grouped into three...
In coastal marine environments, the renewal of necto-benthic Teleost populations depends on availability various essential habitats at key stages in species' life cycle, notably spawning and nursery habitats. The creation strong protection zones (“no-take zones”) is effective protecting adult breeding populations; however, require a different type protection, to protect them from transformation their characteristics, role; moreover, species use within habitat mosaic, or successively during...
Marine heatwaves (MHWs) have been intensifying in frequency and magnitude, posing significant threats to marine biodiversity, particularly sessile benthic species such as the red gorgonian, Paramuricea clavata. This study examines status of P. clavata populations upper mesophotic zone (30 m – 60 m) French Mediterranean, a depth range that may offer partial refuge from MHW events. By analyzing data more than 40 populations, we evaluate health, density, growth dynamics these context rising...
Human activities facilitate coastal habitat transformation and homogenization. The spread of marine invasive species is one example. This in turn may influence fish recruitment the subsequent replenishment adult assemblages. We tested complexity effect on (Teleostei) by experimentally manipulating meadows habitat-forming macroalga Caulerpa taxifolia (Chlorophyta). Among fourteen recorded during experiment, only two labrids (Coris julis Symphodus ocellatus) settled abundance among these...
Climate change has accelerated the occurrence and severity of heatwaves in Mediterranean Sea poses a significant threat to octocoral species that form foundation marine animal forests (MAFs). As coral health intricately relies on symbiotic relationships established between corals microbial communities, our goal was gain deeper understanding role bacteria observed tissue loss key following unprecedented 2022.Using amplicon sequencing taxon-specific qPCR analyses, we unexpectedly found...
This work aimed at performing a large scale assessment of Diplodus spp. (Sparidae) nurseries along the rocky shore Marseilles (France, NW Mediterranean) by locating and quantifying nursery microhabitats estimating settlement pattern this in 2004. Nursery grounds represented only 9% 52 km-long Marseilles. Their location, shallow habitats sheltered within coves, made them vulnerable to human-induced habitat transformations. D. vulgaris settled coast end February 2004 puntazzo couple months...
The sublittoral forests formed by the fucoid algae Cystoseira spp. are important juvenile habitats for many Mediterranean fish species. However, spatial variability of assemblages within and potential environmental drivers, such as depth habitat complexity, remain poorly understood. We estimated densities, sizes behaviours in subtidal (0-15 meters) brachycarpa var. balearica north Minorca Island (North-western Sea) over two consecutive autumns (2012 2013). Depth forest here measured canopy...
Man‐made infrastructures have become ubiquitous components of coastal landscapes, leading to habitat modification that affects the abundance and diversity marine organisms. Marine fish a complex life cycle requiring different essential habitats. One these habitats is known as nursery, place where juveniles can settle in large numbers, survive, grow contribute adult population. Nurseries are mainly found shallow, sheltered zones thus particularly impacted by urbanization, notably harbors. The...
Survival during the settlement window is a limiting variable for recruitment. The survival believed to be strongly determined by biological interactions and sea conditions, however it has been poorly investigated. We examined patterns related relevant biotic abiotic factors (i.e. Density-dependence, wind stress, wave height coastal current velocity) potentially determining post-settler rates of necto-benthic fish wide distribution in Mediterranean eastern Atlantic, white seabream (Diplodus...
Gorgonian octocorals are threatened by global and local stressors that can act synergistically to affect their health. In recent years, mass mortality events triggered marine heatwaves have caused demographic declines in Mediterranean gorgonian populations may lead collapse. Potential changes microbiome composition under stressful conditions further increase the susceptibility of holobiont disease. Given low recovery capacity gorgonians, restoration approaches using transplantation becoming...
Abstract. Early-life stages play a key role in the dynamics of bipartite life cycle marine fish populations. Difficult to monitor, observations these are often scattered space and time. While Mediterranean coastlines have been surveyed, no effort has made assemble historical observations. Here we build an exhaustive compilation dispersal traits for coastal species, considering situ growth models (Di Stefano et al., 2023; https://doi.org/10.17882/91148). Our database contains over 110 000...
