Description
Rivers suffer from a wide range of human impacts that need to be studied (Oscoz, 2003). The ecologic quality of the Larraun river was analysed between 1996 and 1998 to assess the impact caused by the building of a new road and industrial activities: water quality, habitat, macroinvertebrates and fish community. The river presented organic pollution near towns and high nitrite levels. Data about fish biometry, age and feeding are given in the study. Some years later, the river was sampled to analyse the evolution of the fish populations after the building of the road.
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 13,912 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Geographic Coverage
The Larraun river is a 19 km long tributary of the Arakil river (Ebro basin, north of Spain).
| Bounding Coordinates | South West [42.86, -2.19], North East [43.16, -1.74] |

Taxonomic Coverage
In total, 14237 individuals, belonging to eight species, were collected. The most abundant family was Cyprinidae (69%). The other two were Salmonidae (28%) and Nemacheilidae (3.1%). One of the species registered was invasive (Oncorhynchus mykiss) and five were endemic (Barbus haasi, Gobio lozanoi, Luciobarbus graellsii, Parachondrostoma miegii and Barbatula quignardi).
| Species | Barbus haasi (Iberian redfin barbel), Gobio lozanoi (Pyrenean gudgeon), Luciobarbus graellsii (Ebro barbel), Parachondrostoma miegii (Ebro nase), Phoxinus bigerri (Pyrenean minnow), Barbatula quignardi (Pyrenean stone loach), Oncorhynchus mykiss (Rainbow trout), Salmo trutta (Brown trout) |

Project Data
The project assessed the quality of the Larraun river using different measurements: water quality, fish community and macroinvertebrate community to determine the impacts of the building of a road and other human activities near it. Years after the building of the road, various localities were sampled to assess the the health of the fish populations and the effect of the restoration measures applied.

| Funding | The collection of this data has been supported with these two projects: - Estudio del río Larraun: informe Ecológico-Ambiental. Hired by Servicio de Caminos of Gobierno de Navarra and the Science and Technology Institute of Navarra (project ZYE-PROY 034, 1996). . - Estudio del río Larraun: informe Ecológico-Ambiental II. Hired by Servicio de Caminos of Gobierno de Navarra and the Science and Technology Institute of Navarra (project ZYE-PROY 035, 1997). |
| Study Area Description | The Larraun River (Ebro basin) is born in Aralar, in the north of Spain and drains a basin of 221 km2 until its end in the Arakil river. The clime is humid and temperate, without dry seasons. The main plant species are oak, beech, ash, alder, elm, birch and poplar. The flow of this river is 244 hm3 per year and varies seasonaly. The sampling points were located in eigh towns: Aitzarreta, Urritza, Iribas, Irurzun, La Ferreria, Latasa, Lecumberri and Muguiro. |

Sampling Methods
The main sampling method was electric fishing. The method used was three-run depletion between two stop-nets. The captured individuals were sedated with 2-phenoxyethanol, identified, counted and measured (total length in mm). Then, fishes were returned to the river. Some specimens were euthanized, studied in the laboratory and deposited on the Museum of Zoology of the University of Navarra (MZNA, Pamplona, Spain). Species identification was performed by J. Oscoz and R. Miranda.
| Study Extent | The specimens were captured in eleven sampling points of eight towns (Aitzarreta, Urritza, Iribas, Irurzun, La Ferreria, Latasa, Lecumberri and Muguiro) of the Larraun River in the years 1996, 1997, 1998, 2005 and 2010. |
|---|---|
| Quality Control | Species identification was performed by R. Miranda and J. Oscoz using suitable literature (Maitland & Linsell 1977) and scientific names were validated using the W. N. Eschmeyer’s Catalog of Fishes (Eschmeyer 2014). Specimens were returned to the river or deposited in the Museum of Zoology of the University of Navarra. Each specimen was labelled with a unique collection number. Darwin test software (v3.3 Ortega-Maqueda and Pando 2008) was used to check out possible mistakes in the coordinates, characters and the format of dates. |
Method step description:
- Specimens were sampled following the procedure described in the Sampling description section. The individuales were identified, measured and released in the majority of cases. Some specimens were euthanized and deposited on the Museum of Zoology of the University of Navarra in labelled jars first with formalin and, more recently, with 70% ethyl alcohol. Field data was revised, digitalised and incorporated to the MZNA database (Zootron v4.5, Ariño 1991). The dataset was exported to DarwinCore v1.4 format and revised to correct errors to adequate it to DarwinCore standars. Metadata information was added and the Darwin Core Archive was incorporated to the Spanish GBIF IPT.

Additional Metadata
The Museum of Zoology (MZNA) was founded in 1980 as a repository of zoological materials originating from research and instructional activities of the department of Environmental Biology (proviously known as the department of Zoology and Ecology) of the University of Navarra. Nowadays MZNA store more than two millions specimens in its climate-controlled facilities. The Museum is a Data Provider for the Global Biodiversity Information Facility (GBIF) and is an Affiliate to the International Commission of Zoological Nomenclature (ICZN). The Museum is also in charge of the curation and management of the Natural History Collections of the School of Science of the University of Navarra (Spain). MZNA attends to reserchers around the world, make loans and accepts deposits.
