Article
Small pelagic fish (SPF) species such as European sardine Sardina pilchardus , European anchovy Engraulis encrasicolus , round sardinella Sardinella aurita and European sprat Sprattus sprattus play important ecological roles in the Mediterranean Sea marine ecosystem. However, changes in SPF abundance and biomass have recently been observed in the b...
Presentation
Spatial-explicit ecosystem models, such as Ecopath with Ecosim and Ecospace (EwE), are useful tools for exploring ecosystem-based management strategies, as they integrate ecological processes, environmental dynamics and human activities. EwE further allows for the spatial-temporal simulation of use and conservation scenarios, helping to prioritize...

Full-text available
To achieve sustainable fisheries implies that resources’ management is carried out in accordance with biologically and ecologically relevant processes. In this context, to infer the boundaries of the genetic stocks along their distribution is crucial to avoid the depletion of genetic diversity induced by fishing pressure. Despite its remarkable eco...
Article
Although there is a great knowledge about individual anthropogenic threats to different fish species in the Mediterranean Sea, little is known about how these threats accumulate and interact to affect fish species richness in conjunction with environmental dynamics. This study assesses the role of these threats in the fish richness component and id...

Climate change is expected to profoundly affect key food production sectors, including fisheries and agriculture. However, the potential impacts of climate change on these sectors are rarely considered jointly, especially below national scales, which can mask substantial variability in how communities will be affected. Here, we combine socioeconomi...
Article
Trophic cascades occur when a reduced abundance of a keystone species, such as a top predator, causes changes in their prey abundance, which in turn affects other trophic levels, such as mesopredators, herbivores and/or plants. They are reported from freshwater, terrestrial, and marine environments. This article describes examples of pelagic and be...
Article
Ecosystem models, such as Ecopath with Ecosim (EwE), are useful tools for developing ecosystem-based management strategies. Model development, however, requires data for the estimation of input parameters including time series for calibration. Most small-scale fisheries lack such information, making it difficult to reliably use ecosystem models for...
