This collection includes information of 2278 records of small mammals distributed in Erro Basin (Navarra) and nearby areas. The study carried out in the basin contributes to the material collection of MZNA with 1798 specimens captured in field and stored in its facilities. The rest of the records correspond to occurrences from field. Material brought to laboratory mainly consists on whole animals (frozen) but there are also skulls, mandibles from barn owl pellets, and skins and skulls from captured specimens prepared. Information about occurrences is also incorporated to the data set. The study took place between 2001 and 2003. The collection also includes biometrics mainly from Apodemus sylvaticus. The data set is available in GBIF.
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 2,278 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.
The table below shows only published versions of the resource that are publicly accessible.

The collection is mainly formed by specimens from Erro Basin but there are also records from other localities nearby the basin.
|Bounding Coordinates||South West [42.76, -1.52], North East [42.97, -1.39]|
Specimens were first identified to genus or species level in field using external morphology. Specimens in doubt were transported to the laboratory where their taxonomic identity was verified using suitable literature (Gosálbez 1987). Some specimens captured in field were selected for deeper studies so they were transported and processed in the laboratory. The collection is composed of 3 orders (Carnivora, Rodentia and Soricomorpha), 6 families and 18 species although the order Carnivora is represented by only 3 records of Mustela nivalis. Muridae is the most abundant family being approximately the 79% of the entire collection followed by Soricidae representing the 12 %. Most of the specimens brought to the laboratory belonged to the species A.sylvaticus and M. spretus.

The aim of the project was to study the changes in the zoological community of Erro Basin due to human activities. The project focused in different animal communities being small mammals one of the taxon studied.

|Study Area Description||Erro Basin is located in the north of Navarra and covers an area of approximately 214 Km2. It is one of the Pyreneean Basins and includes the municipalities of Erro, Lizoáin, Urroz and Lónguida.|
|Design Description||The project was conducted between 2001 and 2003 but the main sampling effort was made in the first two years. Fifteen sampling sites were selected and at least were sampled twice in each season using Sherman traps. Eleven more localities were chosen to sample the small mammal’s community using pitfalls traps during the first year of the project.|
The personnel involved in the project:
Fifteen sites were sampled from 2001 to 2003, doing at least two sampling each season in every site. Sherman traps (7,5x9x23 cm) baited with bread and oil were used. Each sampling event consisted on two nights and the total sampling effort made was 160 traps per night. Specimens were sexed and identified in field when possible. Some of the specimens captured were transported to the laboratory for further studies. In addition eleven sites were sampled using pitfall traps in order to get a better knowledge of the small mammals’ community due to the bias of using only one type of sampling method. Each sampling site was composed of six cylindrical jars (11,5 cm diameter and 13,5 cm depth) which were active from May to November 2001. Barn owl pellets, information about footprints and other mammal trails were collected during the sampling period.
|Study Extent||The Erro River Basin is located in the north of Navarra in the western side of the Pyrenees. Its climate conditions suffer a strong change between the source of the river influenced by the Pyreneans’ climate to the mouth of the Erro where the climate becomes more Mediterranean. From north to south rainfall decreases in contrast to the temperature which increases as it reaches south. Erro Basin is characterized by a wide range of landscapes which has a positive effect on the flora and fauna diversity. The headwater’s area and the middle section of the basin are dominated by oaks and beech forests, pastures and forestry exploitation mostly consisting on pines. The last section is dominated by crops and cattle grazing fields (Rivas 1987).|
|Quality Control||All specimens collected from the field are deposited in the Museum of Zoology of the University of Navarra (MZNA, Pamplona, Spain) in the ‘Colección de Actuaciones humanas en el río Erro’. All the species were sexed and identified in field (when possible) and the taxonomic identity of each specimen brought to the laboratory was verified by David Galicia using suitable literature (Gosálbez 1987, Niethammer and Krapp 1978, 1982, 1990). Scientific names were validated according to Mammal Species of the World (Wilson and Reeder 2005, Palomo et al. 2007). Unique collections’ accession numbers were assigned to each specimen.|
Method step description:
- All captured specimens where sexed and identified in field. Most of the specimens captured the first year were selected for further studies in laboratory. Specimens which identification was in doubt were also taken to the laboratory. Specimens brought to the laboratory were euthanized and frozen at -20ºC. Then, they were measured (tail length, body length, ear length, hind foot length, fore foot length) and weighted (body weight and eviscerated weight). After that, some specimens were selected and processed for a deeper study. Skin was removed and preserved dried. Skull, mandibles and some skeleton parts (scapula bones) were obtained and placed in plastic bags. Information of each record was systematically incorporated to MZNA database (Zootron v4.5, Ariño 1991).

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.
|Purpose||The aim of the present data set is to provide all information of the records of small mammals derived from the study carried out in the Erro Basin.|
|Maintenance Description||Dataset is closed. The regular maintenance of the preserved material could imply modification of some metadata related with curatorial units. New versions of the dataset will be published when required.|
