Mammals in MZNA-VERT: pellet samplingAcronym: MAST-MMEG
This collection includes information of small mammals' records obtained from the analysis of barn owl pellets. Most of the material has been collected in the region of Navarra, Spain, although other localities of the Iberian Peninsula are also included. The collection is stored in the holdings of the Museum of Zoology of the University of Navarra (MZNA) and is composed by skulls, mandibles and few skeletons of 36 species of more than 72000 georeferenced specimens. Records date from 1967 to the present covering a period of 50 years. Thus, this collection can be used in studies dealing with distribution patterns of small mammals and their changes over time which can be interesting and useful in conservation planning. The data set is available in GBIF.
The collection is primarily formed by specimens from the region of Navarra (75,38%), north of Spain. It also contains specimens from other administrative territories of Spain such as Huesca, Zaragoza and Cáceres.
The aim of the present data set is to provide all information of the records of small mammals from barn owl pellets stored in MZNA. Due to the different sources of the samples, an effort to standardize those records has been made in order to share them through GBIF.
All specimens are deposited in the Zoological Museum of the University of Navarra (MZNA, Pamplona, Spain) in ‘Pellet sampling’ collection.
Identification of most of specimens was verified in the laboratory by Carmen Escala 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.
Coordinates in UTM/MGRS were transformed to geographic system. The consistency of all records was checked by visual inspection overlapping coordinates with a Europe map using GIS (Chapman 2005) and their uncertainty was calculated in metres using the point-radius method.
The ‘Pellet sampling’ collection started in the sixties but most of the sampling effort was made between 1968 and 1993 in order to elaborate the ‘Atlas de los insectívoros y roedores de Navarra. Análisis biogeográfico’ (Escala et al., 1997). During all this period there have also been contributions from different sources: research projects, PhD researches, student’s works, donations, volunteers and occasional pellet sampling. The number of specimens has increased all these years reaching more than 73000 records. Material brought to the laboratory was processed, identified and placed in plastic bags. Once identified, data of each specimen was systematically incorporated to MZNA database (Zootron v4.5, Ariño 1991).
