A user’s guide for EuroDiad 4.0

EuroDiad is a database that contains distribution and life-history trait information for twenty-eight diadromous species and geomorphological data for each of the selected river catchments.

If you are a user of EuroDiad, this document, ellaborated by DiadES partners, will provide you with information about the distribution of diadromous species (i.e. jawless fish and fish) found in continental waters in Europe, the Middle East, and North Africa from 1750 to present time. Information was gathered for 28 diadromous species (i.e. anadromous and catadromous) in this geographical area. Data for version 4.0 were validated by DiadES project partners. The primary goal of this update was to provide information for a new generation of species distribution models, referred to as hybrid models, which incorporate both habitat suitability and population dynamics within their framework. The objectives of this update were to: a) incorporate new catchments for which information was provided by project partners, b) validate existing information about the presence or absence of diadromous species and categorize their abundance or population functionality within a catchment, and c) perform data hygiene to prepare the database for broad dissemination.
