The introduction of invasive alien species (IAS) and the occurrence of jellyfish blooms and harmful algal blooms (HABs) can significantly alter native biodiversity and disrupt ecosystem functioning. This study expands the Cumulative IMPacts of invasive ALien species (CIMPAL) index to assess the cumulative impacts of IAS, HABs, and jellyfish blooms, also accounting for interspecific interactions. The approach is implemented in...

The conservation and management of marine ecosystems hinge on a comprehensive understanding of the status and trends of top predators. This review delves into the ecological significance of marine top predators, examining their roles in maintaining ecosystem stability and functioning through an integrated analysis of current scientific literature. We first assess the efficacy of various monitoring methods, ranging from traditi...

In the Mediterranean Sea, the genus Pinna encompasses two large fan-shaped bivalve species, Pinna nobilis and Pinna rudis. Historically, both species coexisted in the western Mediterranean until a mass mortality event (MME) brought P. nobilis to the brink of extinction. Notably, P. rudis remained unaffected by the MME, and its recent successful recruitment and further spread have been hypothesized to be linked to the local ext...
