Context-dependent interplays between truncated demographies and climate variation shape the population growth rate of a harvested species ArchiMer
Hidalgo, Manuel; Rouyer, Tristan; Bartolino, Valerio; Cervino, Santiago; Ciannelli, Lorenzo; Massuti, Enric; Jadaud, Angelique; Saborido-rey, Fran; Durant, Joel M.; Santurtun, Marina; Pineiro, Carmen; Stenseth, Nils C..
Fisheries ecologists traditionally aimed at disentangling climate and fishing effects from the population dynamics of exploited marine fish stocks. However, recent studies have shown that internal characteristics and external forcing (climate and exploitation) have interactive rather than additive effects. Thought most of these studies explored how demographic truncation induced by exploitation affected the response of recruitment to climate, identifying a general pattern revealed to be difficult as interactions are often case-specific. Here we compared five exploited stocks of European hake Merluccius merluccius from the Atlantic Ocean and Mediterranean Sea to investigate how the interaction between internal characteristics and external forces affect the...

Increasing human pressures and global environmental change may severely affect the diversity of species assemblages and associated ecosystem services. Despite the recent interest in phylogenetic and functional diversity, our knowledge on large spatio-temporal patterns of demersal fish diversity sampled by trawling remains still incomplete, notably in the Mediterranean Sea, one of the most threatened marine regions of the world. We investigated large spatio-temporal diversity patterns by analysing a dataset of 19,886 hauls from 10 to 800 m depth performed annually during the last two decades by standardized scientific bottom trawl field surveys across the Mediterranean Sea, within the MEDITS program. A multi-component (eight diversity indices) and...

The MEDITS trawl survey specifications in an ecosystem approach to fishery management ArchiMer
Spedicato, Maria Teresa; Massuti, Enric; Merigot, Bastien; Tserpes, George; Jadaud, Angelique; Relini, Giulio.
The MEDITS programme started in 1994 in the Mediterranean with the cooperation among research institutes from four countries: France, Greece, Italy and Spain. Over the years, until the advent of the European framework for the collection and management of fisheries data (the Data Collection Framework. DCF), new partners from Slovenia, Croatia. Albania, Montenegro, Malta and Cyprus joined MEDITS. The FAO regional projects facilitated the cooperation with non-European countries. MEDITS applies a common sampling protocol and methodology for sample collection, data storage and data quality checks (RoME routines). For many years, MEDITS represented the most important data source supporting the evaluation of demersal resources by means of population and community...
