Freshwater samples in MZNA-INV-FRW: Macroinvertebrate samples from the water quality monitoring network along the Ebro Basin

Description :


This dataset gathers information about the macroinvertebrate samples collected on rivers and streams of the Ebro River Basin (NE Iberian Peninsula), the second largest catchment in the Iberian Peninsula. The aim was to use freshwater macroinvertebrates to calculate the biological indices required to evaluate the ecological status of the open water bodies within this basin. This dataset is a part of a monitoring network set up by the Confederación Hidrográfica del Ebro (hereinafter CHE). This network was established to fulfill the requirements of the European Water Framework Directive (hereinafter WFD).

The collection is composed of 1776 sampling events carried out between 2005 and 2015 at more than 400 sampling sites. Environmental variables at each sampling site were also recorded to characterise the habitat, and can be found in the MeasurementOrFacts extension (eMoF) uploaded along with the sampling event dataset. All measurements were obtained from the CHE portal (CHE, 2017).

The Museum of Zoology of the University of Navarra (hereinafter MZNA) curates the material obtained during these samplings. Samples were qualitatively screened for all occurring taxa, and all individuals from all taxa in a quantitative subsample of each sample were counted. Biological indices were calculated to estimate water quality at each sampling site. An occurrence extension is also available gathering the abundance of each taxon within the dataset.

Link GBIF portal : Project : Title : Explotación de la red de Control Ecológico de Ríos en la Cuenca del Ebro en aplicación de la Directiva Marco del Agua [Assesment of ecological status of rivers in the Ebro Basin under the Water Framework Directive] Abstract : This project aimed to assess the ecological status of the surface water bodies of Ebro River Basin using biotic and hidromorphological indices. The CHE was the organism in charge of implementing this monitoring network following the indications given by the Water Frame Directive (European Parliament & European Council, 2000). The “Control del Estado de las Masas de Agua Superficiales” (hereinafter CEMAS) was the monitoring network established to evaluate the water quality using biological indices. This project mainly consisted of seasonal samplings in each year from 2005 onwards to study physical-chemical and biological parameters of the open water bodies. Aquatic macroinvertebrates were sampled to calculate the biotic indices. This dataset is the corrected output of this monitoring network. At the time of writingthe monitoring network is operational and the samplings are ongoing. Funding : Ministerio de Agricultura y Pesca, Alimentación y Medio Ambiente. Gobierno de España. Contact : () Le jeu de données diffusé est issu d'un traitement automatique appliqué sur les données issues du GBIF. Les règles de l'INPN et plus globalement du SINP (en termes de périmètre et de contrôle sur les données) peuvent impliquer que l'ensemble des données du jeu source ne soit pas restitué dans le SINP. The disseminated dataset stems from an automatic treatment applied to data coming from GBIF. INPN rules, and more generally SINP rules (in terms of perimeter and data quality controls) may imply that the whole of the source dataset might not be provided on the SINP platform.
