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.

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.

|研究區域描述||The Ebro River Basin is situated in the Northeast of Spain (Western Europe) and drains an area of 85.362 km2. It extends from the western Pyrenees to the south of the Iberian Mountains and the Catalonian coast, discharging into the Mediterranean Sea near Tortosa at the Ebro Delta. Its main 702 tributaries run for an accumulate 12000 km. The prevailing climate of the basin is Mediterranean with 620 mm precipitation per year. A total of 906 000 ha is dedicated to irrigated crops (CHE, 2017).|
|研究設計描述||This monitoring network was designed according to the criteria set up by the WFD. Before the implementation of the WFD, the CHE had already been conducting macroinvertebratesamplings to evaluate the water quality. Nevertheless, in 2005 the CHE changed the previous monitoring network design to adapt it to the new guidelines of the WFD (Jáimez-Cuéllar et al., 2006; CHE, 2017) in such a way that the data obtained could be comparable to other monitoring networks. For detailed information of the monitoring network consult the annual reports (CHE, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015)|
1. Fieldwork At each sampling site, five types of habitats were selected: hard substrates, plant debris, bank bordered by vegetation, submerged macrophytes (if present), sand and other fine sediments. Once identified the microhabitats and the area occupied by each one, the sampling units (kicks) were distributed proportionally to the area of each habitat in the section. As a general rule, twenty sampling units were used. Macroinvertebrates were collected using a hand-net (25 cm x 25 cm aperture, 500-µm-mesh size). In each sampling unit (kick), the substrate was removed 0.5 m in front of the mouth of the net. The final sampled area resulting from the twenty sampling units was approximately 2.5 m2. Samples were fixed in 4% buffered formaldehyde, stored in plastic sealed jars, labeled and brought to the laboratory. Simultaneously, electrical conductivity (precision 1 µS/cm), dissolved oxygen (precision 0.01 mg/L), temperature (precision 0.1°C) and pH were measured using a multi-parameter water quality monitoring system (WTW Multi 340i) at each sampling. Each instrument was calibrated daily during the sampling period. 2. Laboratory work Samples were transported to the laboratory for analysis. The samples were sieved through 5 mm, 1 mm and 0,5 mm mesh sieves. Then, the material was washed with abundant running water, separating the organisms from the remaining debris, gravel, and sand. Finally, the sample was divided into the respective fractions of the sieves: •5mm fraction: all organisms were identified to the taxon level required by the IBMWP index and counted. •1 mm and 0.5 mm fractions: organisms were identified to the taxon level required for the IBMWP index. Samples were divided into subsamples (eg., one-quarter size) and organisms from one subsample were counted.Total abundance of each taxon was estimated from the subsample counts. The remaining sample (eg., the uncounted three-quarters of the sample) was examined for families not caught in the subsample, but organisms were not counted. For further details, see Wrona, Culp & Davies, 1982. •Finally, all the material was stored in plastic jars with 70°ethlyl alcohol, labeled and stored at the MZNA facilities. After processing the samples, the IBMWP and IASPT scores were calculated (Alba-Tercedor, J., P. Jaimez-Cuellar et al., 2002). More details of the sampling protocol can be found in “Protocolo De Muestreo Y Laboratorio De Fauna Bentónica De Invertebrados En Ríos Vadeables” (MAGRAMA, 2013). The environmental variables, the biological indices, and the occurrences can be found in the MeasurementsOrFacts and Occurrence extensions respectively, uploaded together with the Sampling Event dataset.
|研究範圍||The Ebro River Basin is situated in the Northeast of the Spain (Western Europe) and drains an area of 85.362 km2. It is the second largest catchment in the Iberian Peninsula and has 702 tributaries and 110 lakes. from the western Pyrenees to the south of the Iberian Mountains, discharging into the Mediterranean Sea. The prevailing climate of the basin is Mediterranean with an average yearly precipitation of 620 mm. The basin hosts a large number of ecosystems from the head of the Ebro River to its mouth. Eurosiberian communities (beech, grasslands) dominate the highest part of the river whereas Mediterranean ones take over in the middle region until the mouth. The water uses of the basin are principally urban water supply, livestock, farming, and industry. However, the highest water consumption comes from agriculture (4,574 hm3/year) dedicated to 906,000 ha of irrigated crops. Samplings were carried out annually from late spring to early autumn when macroinvertebrate communities reach their highest diversity, although samplings could be postponed to summer in the case of unfavorable environmental conditions such as high rainfall in elevated areas (e.g., the Pyrenees). Likewise, in the event of floods, samplings were conducted 15 days after the incident.Temporary streams were sampled when the conditions were optimal, that is, in the presence of running water. A total of 473 sampling sites belonging to the CEMAS network were sampled from 2005 to 2015. Each sampling site covered a selected 100-m segment of the river having the essential habitats of that river’s stretch. Therefore, all the data obtained was assumed to be representative of that stretch of the river, and all variety of habitats were sampled. The following features were taken into account for selecting a segment: •The presence of rapid-slow running water. •Fluvial Morphology. For example, natural courses were chosen over channeled water. •Vegetation cover. Shady areas were avoided if they were not characteristic of the stretch. •Areas near bridges and weirs were avoided unless they were representative of the stretch. •Accessibility. Sampling sites were accessible and crossable.|
|品質控管||Specimen identification was carried by Javier Oscoz using suitable literature (Tachet et al., 2000; Oscoz, Galicia & Miranda, 2011). Scientific names were validated according to the GBIF Backbone Taxonomy (GBIF, 2017). All samples were fully analyzed for the entire range of potential taxa. Taxon absences recorded in the dataset are thus true absences as regards to the taxa listed in the IBMWP indices. The MZNA stores samples from 2005 to 2015 derived from the monitoring network. Field data was digitalized and incorporated into the MZNA database (Ariño, 1991). Unique accession numbers were assigned to each sample. The dataset was standardized to the Darwin Core standards. Guidelines by Chapman (2005) were followed to check for taxonomical, geographical and temporal errors in the dataset. Coordinates in UTM/MGRS were transformed to the geographic system. The consistency of all records was inspected by overlapping sampling site coordinates with a map of the Ebro Basin (CHE, 2017). The entire process of debugging the dataset was done with R version 3.3.2 (R Core Team, 2016). Packages used included rgdal (Pebesma, Sumner & Hijmans, 2013), sp (Pebesma & Bivand, 2005) for geographic data and reshape2 (Wickham, 2007) for handling with the dataset.|
