An important principle of environmental science is that changes in single components systems are likely to have consequences elsewhere the same systems. In sea, food web data one few foundations for predicting such indirect effects, whether fishery exploitation or following recovery marine protected areas (MPAs). We review available literature on type interaction benthic ecosystems, namely trophic cascades, which involve three more levels connected by predation. Because many effects been...
Abstract Marine protected areas (MPAs) have largely proven to be effective tools for conserving marine ecosystem, while socio-economic benefits generated by MPAs fisheries are still under debate. Many embed a no-take zone, aiming preserve natural populations and ecosystems, within buffer zone where potentially sustainable activities allowed. Small-scale (SSF) zones can highly beneficial promoting local socio-economies. However, guidelines successfully manage SSFs MPAs, ensuring both...
Managing invasive alien species is particularly challenging in the ocean mainly because marine ecosystems are highly connected across broad spatial scales. Eradication of has only been achieved when were detected early, and management responded rapidly. Generalized approaches, transferable regions, for prioritizing actions to control populations currently lacking. Here, expert knowledge was elicited prioritize 11 controlling 12 model species, distinguished by differences dispersion capacity,...
Abstract. Observations of the fish fauna Posidonia oceanica (L.) DELILE seagrass beds were undertaken in two shallow stations and one deeper station Port‐Cros National Park, between November 1984 September 1987. Demographic structure, density biomass 19 most abundant species or taxa assessed by several non‐destructive sampling methods. The assemblages studied dominated number a small (Labridae: Symphodus ocellatus S. tinca ; Sparidae: Diplodus annularis Sarpa salpa ). Large individuals...
The aim of the present work is to broaden our knowledge on variability trace metals in mussel tissues, focusing seasonal fluctuations three different sampling sites Algerian west coast (Oran Harbor (S1), Ain Defla (S2) and Hadjaj (S3)). For this purpose, bioavailability (metal indices) bioaccumulation concentrations soft tissues) heavy (Zn, Cu, Pb, Cd), physiological characteristics (e.g. biological indices such as condition index (CI)) mussels Mytilus galloprovincialis have been assessed...
Abstract The spectre of increasing impacts on exploited fish stocks in consequence warmer climate conditions has become a major concern over the last decades. It is now imperative to improve way we project effects future warming fisheries. While estimating climate‐induced changes distribution an important contribution sustainable resource management, European small pelagic fish—representing 50% landings Mediterranean and Black Sea between 2000 2013—are yet largely understudied. Here,...
1. A study was set up in the Port-Cros National Park order to determine effects of boat anchoring on Posidonia oceanica seagrass beds. 2. Experiments anchors meadows revealed that, average, 34 shoots were destroyed during an cycle (lock-in and retrieval), especially when mat compactness is weak extent rhizome baring high. 3. Five parameters beds (meadow cover, shoot density, baring, proportion plagiotropic rhizomes, degree meadow fragmentation) considered it shown that not correlated with...
Abstract. Fishes associated with the seagrass Posidonia oceanica were censused both by skid trawl and visual counts around Ischia Island, Italy. Both sampling procedures performed during day in summer winter at two sites. Significant differences number of species, individuals, biomass, trophic structure fish assemblage observed between methods. Fewer species recorded than trawling. More individuals a greater however, from counts. The population macrocarnivores (Scorpaenidae, Serranidae)...
Temperate marine rocky habitats may be alternatively characterized by well vegetated macroalgal assemblages or barren grounds, as a consequence of direct and indirect human impacts (e.g. overfishing) grazing pressure herbivorous organisms. In future scenarios ocean acidification, calcifying organisms are expected to less competitive: among these two key elements the subtidal food web, coralline algae sea urchins. order highlight how effects increased pCO2 on individual species will...
Cystoseira species are some of the most important marine ecosystem-engineers, forming extended canopies comparable to land forests. Such forests sensitive human disturbances, like decrease in water quality, coastal development and outbreak herbivores. Conspicuous historical declines have been reported many regions several presently protected by European Union (EU) environmental policies. The aim this work was synthesize conservation perspectives Mediterranean Sea, focusing on opportunities...
Marine Protected Areas (MPAs) are an essential tool for marine biodiversity conservation. Yet, their effectiveness in protecting ecosystems from global stressors is debated. Biological invasions a major driver of change, causing loss and altering ecosystem functioning. Here, we explored the relationships between MPAs alien/native range-expanding fishes Mediterranean Sea, world's most invaded sea. We surveyed fish benthic communities nine adjacent unprotected areas across six countries. In...

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...
