The species interaction and their biological traits (BT) determine the function of benthic communities and, hence,
the delivery of ecosystem services. Therefore, disturbance of benthic communities by trawling may compromise
ecosystem service delivery, including fisheries' catches. In this work, we explore 1) the impact of trawling activities
on benthic functional components (after the BTA approach) and 2) how trawling impact may affect the ecosystem
services delivered by benthic communities. To this aim, we assessed the provision of ecosystem services
by adopting the concept of Ecosystem Service Providers (ESP), i.e. ecological units that perform ecosystem functions
that will ultimately deliver ecosystem services.We studied thirteen sites subjected to different levels of fishing
effort in the Mediterranean. From a range of environmental variables included in the study, we found ESPs to
be mainly affected by fishing effort and grain size. Our results suggested that habitat type has significant effects
on the distribution of ESPs and this natural variability influences ESP response to trawling at a specific site. In
order to summarize the complex relationships between human uses, ecosystem components and the demand
for ecosystem services in trawling grounds, we adapted a DPSIR (Drivers–Pressures–State Change–Impact–
Response) framework to the study area, emphasizing the role of society as Drivers of change and actors demanding
management Responses. This integrative framework aims to inform managers about the interactions between all
the elements involved in the management of trawling grounds, highlighting the need for an integrated approach
in order to ensure ecosystem service provision.
