Mammals in MZNA-VERT: project Loza
This collection includes information of small mammals’ community found in Loza lagoon shores (Navarra, Spain). The study was carried out in Loza in 2007 and contains information of eight mammal species. The database is formed by 208 occurrences and 18 preserved specimens which are stored in MZNA facilities. This collection is only a part of a large project carried out in Loza in which the purpose was to study the flora and fauna of this lagoon. 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 220 records.
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.

|Bounding Coordinates||South West [42.83, -1.73], North East [42.84, -1.71]|
Specimens were identified to species level in field using external morphology. The collection is composed of orders Carnivora, Rodentia and Soricomorpha, 4 families and 8 species although the order Carnivora is represented by only 3 records of Mustela nivalis. Muridae is the most abundant family followed by Soricidae and Cricetidae. The most abundance species is Apodemus sylvaticus (181 records).
|Order||Carnivora, Rodentia, Soricomorpha|
|Family||Cricetidae, Muridae, Mustelidae, Soricidae|
|Genus||Apodemus, Crocidura, Microtus, Mus, Mustela, Neomys, Sorex|
|Species||Apodemus sylvaticus (Long-tailed field mouse), Crocidura russula (Greater white-toothed shrew), Microtus agrestis (Field vole), Microtus duodecimcostatus (Mediterranean pine vole), Mus spretus (Western mediterranean mouse), Mustela nivalis (Least weasel), Neomys fodiens (Eurasian water shrew), Sorex coronatus (Millet's shrew)|
|Living Time Period||2007|
Sampling was conducted between February and October in 2007. Sherman traps (7,5x9x23 cm) were placed along a habitat gradient varying from pastures to scrubland following a transect. The distance between traps was approximately 10 metres. Only half of the traps were baited in order to avoid bias due to the baiting. Each sampling event consisted on four nights. Traps were placed first night and checked for animals the four days after. The total sampling effort made was 800 traps per night. Specimens were sexed, identified in field using external morphology and then released. In addition few barn owl pellets were collected within the study area during the sampling period for completing the sampling.
|Study Extent||Loza Lagoon is situated in Pamplona’s Basin in the centre of Navarra (Spain). Lagoons play an important role in biodiversity conservation as they constitute a stopover for migrants’ birds. Lagoons in Navarra are mainly located in the south whereas Loza is one of the most northern lagoons in Navarra. Land cover in Loza is characterised by prairies, scrubland, reed bed patches and some black poplar as well. Crops and pine repopulations enclose the lagoon (Arizaga et al, 2009).|
|Quality Control||All specimens collected in the field are deposited in the Museum of Zoology of the University of Navarra (MZNA, Pamplona, Spain) in the ‘Project Loza’ collection. All the species were sexed and identified in field by Carmen Escala and David Galicia. Specimens from pellets were identified using suitable literature (Gosálbez 1987). Scientific names were validated according to Mammal Species of the World (Wilson and Reeder 2005, Palomo et al. 2007). Coordinates in UTM/MGRS were transformed to geographic system. The consistency of all records was checked by visual inspection overlapping coordinates with a Navarra map using GIS (Chapman 2005) and their uncertainty was calculated in metres using the point-radius method.|
Method step description:
- Barn owl pellets were frozen at -20ºC for removing bugs. After that, pellets were dissected and skulls, mandibles and other bones were separated for taxonomic identification. Specimens were identified using a stereoscopic microscope and appropriate literature (Gosálbez 1987). Finally, specimens were placed in plastic bags with their unique catalogue number and stored in the museum facilities. Specimens found dead were transported to laboratory where the skull was prepared. First, specimens were dissected separating skull and axial skeleton from the rest of the body. Then, they were boiled and flesh was removed from the bones. Once dried, they were placed in zip plastic bags with their unique catalogue number. From some specimens following measures were obtained: body length, tail length, ear length and hind foot length. Information about specimens and occurrence was 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). The 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 from the project conducted in Loza Lagoon.|
|Maintenance Description||This collection is closed to new incorporation of data as the project was finished in 2007.|
