Географический охват

Sierra Nevada is a mountain system located in the South of the Iberian Peninsula (Spain), shared by the provinces of Granada and Almería, and with an East-West arrangement. It covers 2,273 km2 and reaches a maximum altitude of 3,479 m a.s.l. in the Mulhacén summit. Due to its meridional situation in Europe, its proximity to the Mediterranean Sea and its high altitude, it represents a high gradient of climatic conditions, with representation of five out of six of the bioclimatic zones present in the Mediterranean region (from the thermo-mediterranean to the crioro-mediterranean). The Sierra Nevada Natural Area has an extensive hydrographic network made up of rivers and streams (as well as high mountain lakes), which are fed mainly by snow from the high peaks. It is worth highlighting the great diversity of ecotypes present, with an important representation of fluvial courses typified as high mountain rivers, Siliceous Mediterranean mountain rivers, Calcareous Mediterranean mountain rivers and mineralised Mediterranean low mountain rivers. This variety of ecotypes promote the existence of a great biodiversity.

Данные проекта

The Sierra Nevada Global-Change Observatory (https://obsnev.es/) is an ambitious project promoted by the Department of Sustainability, Environment and Blue Economy of the Regional Government of Andalusia with the scientific coordination of the University of Granada, in order to monitor the effects of global change in the Sierra Nevada protected area. For this purpose, the Sierra Nevada Global-Change Observatory has developed a monitoring programme and an information system for appropriate data management. As part of this programme, a monitoring methodology was defined to long-term monitor brown trout populations (Galiana et al, 2014).

Методы сбора

Field samplings are conducted by means of electrofishing qualitative surveys. To minimize fish mortality, electric current intensity is regulated depending on water conductivity (Johnson et al. 2007) at every sampling site. Fork length and weight data are collected for all fish captured during each electric fishing pass. Age is determined using a combination of length-frequency analysis following Petersen (1896) and scale-based method described by Steinmetz & Muller (1991) and Hining & West (2000). For more precise age determination, scales are collected from the area between the lateral line and dorsal fin of fish near age class boundaries and are subsequently analysed in the laboratory. Fulton's condition factor (Anderson & Neumann, 1996) was used to assess the condition of the trout individuals. Site habitat characteristics are annually recorded at each sampling station by applying specific sampling techniques for each case. These features include physiogeographic and values for quality indices: Cover Index (according to García de Jalón and Schmidt, 1995), Habitat Suitability Index (according to Consejería de Medio Ambiente y Ordenación del Territorio, 2014), Riparian Quality Index and Fluvial Habitat Index (according to Jáimez-Cuéllar et al., 2002).

Описание этапа методики:

1. 1. All data is stored in Linaria (https://linaria.obsnev.es/), the institutional data repository of the Sierra Nevada Global-Change Observatory. 2. The dataset was standardised to the Darwin Core format (DwC-A) as sampling event data according to the structure proposed by De Pooter et al. (2017): an Event Core in combination with an Occurrence Extension and an Extended Measurement or Fact Extension. The DwC-A contains, specifically: 156 events, 8,000 occurrences, and 45,138 records of associated measurements (45 variables: 5 associated to occurrences and 40 to sampling events). The Darwin Core elements included in the Event Core are: eventID, modified, language, institutionCode, ownerInstitutionCode, datasetName, license, eventDate, year, month, day, continent, country, countryCode, waterBody, locationID, locationRemarks, minimumElevationInMeters, maximumElevationInMeters, decimalLatitude, decimalLongitude, geodeticDatum, samplingProtocol, sampleSizeValue, sampleSizeUnit, occurrenceStatus, eventRemarks. For the Occurrence Extension are: occurrenceID, collectionCode, eventID, eventDate, organismQuantity, organismQuantityType, basisOfRecord, scientificName, taxonRank, kingdom, phylum, class, order, family, genus, specificEpithet, scientificNameAuthorship. For the Extended Measurement or Fact Extension table, the Darwin Core elements included are: measurementID, eventID, occurrenceID, measurementType, measurementValue, measurementUnit and measurementMethod. 3. The resulting dataset was published through the Integrated Publishing Toolkit of the Spanish node of the Global Biodiversity Information Facility (GBIF) (http://ipt.gbif.es).
