Mammals in MZNA-VERT: biology of Arvicola sapidus in Navarra. PhD project, Juan Manuel GardeAcronym: MAST-ARSA
This dataset contains information of 421 records of Arvicola sapidus and records of other small mammals distributed in Ribera Alta (Navarra, Spain). All specimens were collected for studying the biology of A.sapidus. The collection includes skeletons, skins and in some cases, tissues from this specie. There are included also skulls and skins from few other species of small mammals trapped during the surveys.
The data set is available in GBIF.
All specimens were sampled in Ribera Alta de Navarra (Spain), mainly in the Aragón’s river bank as it passes through the locality of Mélida (Navarra).
The aim of the present data set is to provide all information collected under the study of the biology of the water vole done by Juan Manuel Garde and stored in MZNA facilities.
All specimens are deposited in the Museum of Zoology of the University of Navarra (MZNA, Pamplona, Spain) in the ‘Biology of Arvicola sapidus in Navarra’.
All specimens of A.sapidus were sexed and identified in by Juan Manuel Garde. Other small mammals captured during the sampling were transported as well to laboratory and identified using suitable literature (Gosálbez 1987). Scientific names have been validated according to Mammal Species of the World (Wilson and Reeder 2005, Palomo et al. 2007). Unique catalogue 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 map of Navarra using GIS (Chapman 2005) and their uncertainty was calculated in metres using the point-radius method.
Specimens of A.sapidus were dissected in laboratory conserving skin, skull, fore and hind limbs and some tissues (crystallines, testicles, ovaries and smear from testicles). First, skin was removed, cleaned with soap and dried using sodium borate. Then, each skin was mounted on a cardboard and stored.
Secondly, each specimen was dissected separating skull, limbs and tissues previously listed. Skeletons parts were boiled and then, flesh was separated from them. Tissues were conserved in alcohol (ETOH).
Biometric data were also taken from most of specimens of water vole. Measures were taken following rules from Comisión de Biometría (1972).
Skulls from the other species were prepared following the same protocol than in the case of A.sapidus.
Information of each specimen was incorporated to MZNA database (Zootron v4.5, Ariño 1991).
