A simulation-based approach to assess the stability of marine food-webs and inform Good Environmental Status
The European Union Marine Strategy Framework Directive (MSFD) recognises that maintaining marine food-webs in Good Environmental Status (GES) is fundamental to ensure the long-term provision of essential ecosystem goods and services. However, operationalising food-web assessments is challenging due…

Metabarcoding analysis of European hake diet in the Mediterranean Sea
European hake (EH), Merluccius merluccius, is a demersal fish distributed from the North Sea and Atlantic to the Levantine Sea in the Mediterranean. EH is an important predator of deep Mediterranean upper shelf slope communities and it is currently characterised by growth overexploitation. EH…

Recent Trends and Impacts of Fisheries Exploitation on Mediterranean Stocks and Ecosystems
This review focuses on the recent data on Mediterranean fishing fleets and landings, results from stock assessments and ecosystem models to provide an overview of the multiple impacts of fishing exploitation in the different Mediterranean geographical sub-areas (GSAs). A fleet of about 73,000…

Coding Early Naturalists' Accounts into Long-Term Fish Community Changes in the Adriatic Sea (1800–2000)
The understanding of fish communities' changes over the past centuries has important implications for conservation policy and marine resource management. However, reconstructing these changes is difficult because information on marine communities before the second half of the 20th century is, in…

Ecosystem Overfishing in the Ocean
Fisheries catches represent a net export of mass and energy that can no longer be used by trophic levels higher than those fished. Thus, exploitation implies a depletion of secondary production of higher trophic levels (here the production of mass and energy by herbivores and carnivores in the…

Global Patterns in Ecological Indicators of Marine Food Webs: A Modelling Approach
Background: Ecological attributes estimated from food web models have the potential to be indicators of good environmental status given their capabilities to describe redundancy, food web changes, and sensitivity to fishing. They can be used as a baseline to show how they might be modified in the…

Long-term contamination by non-native fish assemblages in a Neotropical floodplain
Biological invasions are a major threat to biodiversity in species-rich regions. Therefore, it is important to understand mechanisms behind the long-term establishment of non-native fish species in aquatic environments in the Neotropical region. Here, we associated fish biomass, species richness…

MAELSTROM, a machine learning-based approach for stock assessment
Managing the fishing industry is crucial to maintain a balance between the exploitation of marine resources and their natural ability to recover. To achieve such a goal, stock assessment models are built to combine commercial catches and population abundance time series. These approaches can often…

DNA metabarcoding suggests dietary niche partitioning in the Adriatic European hake
Abstract The Northern Adriatic Sea (FAO Geographical Sub-Area 17) is one of the most productive fishing areas of the Mediterranean Sea and it includes a broad diversity of habitats. In the Northern Adriatic basin, the Pomo Pit (200–273 m of depth) is one of the most important areas of aggregation…

Rewiring and indirect effects underpin modularity reshuffling in a marine food web under environmental shifts
Abstract Species are characterized by physiological and behavioral plasticity, which is part of their response to environmental shifts. Nonetheless, the collective response of ecological communities to environmental shifts cannot be predicted from the simple sum of individual species responses…

Planktonic ecological networks support quantification of changes in ecosystem health and functioning
Abstract Plankton communities are the foundation of marine food webs and have a large effect on the dynamics of entire ecosystems. Changes in physicochemical factors strongly influence planktonic organisms and their turnover rates, making their communities useful for monitoring ecosystem health. We…

Who Is Where in Marine Food Webs? A Trait-Based Analysis of Network Positions
Networks of trophic interactions provide a lot of information on the functioning of marine ecosystems. Beyond feeding habits, three additional traits (mobility, size, and habitat) of various organisms can complement this trophic view. The combination of traits and food web positions are studied…

Bottom trawling and environmental variables drive the biodiversity of mediterranean demersal assemblages
Abstract Marine ecosystems are healthy with a high degree of biodiversity. Assessing how factors affect spatial and temporal patterns of biodiversity is an essential task for the Ecosystem Based Management approach. In this work, we investigated the effect of fisheries disturbance and ocean…
