The evaluation of the status of marine communities, and especially the monitoring of those heavily exploited by fisheries, is a key, challenging task in marine sciences. Fishing activities are a major source of disruption to marine food webs, both directly, by selectively removing components at specific trophic levels (TL), and indirectly, by alter...

Marine ecosystems are changing rapidly due to ocean warming, overfishing and a raft of other anthropogenic impacts. Such changes are expected to disrupt productivity dynamics and alter marine food webs, with likely negative consequences for ecosystem services. It is, therefore, essential to devise and implement methods that can rapidly and inexpens...

Fisheries and ecosystem services are sustained by a network of species interactions, whose functioning and resilience can be altered by changes in primary and secondary production, over-harvesting of staple species, and climatic shifts. Commercially targeted species are known to be affected by sudden changes in abundances of other organisms sitting...
