The mammal collections of the Estación Biológica de Doñana (EBD) were mainly originated as result of different biodiversity projects of the Institute, including several PhD works, that were carried out during the sixties and seventies world-wide. They were initiated to fulfil the necessity of reference systematic material that was hardly accessible in Spain at that time. Despite being relatively young, the collections are already of outstanding scientific interest not only because of the volume of specimens housed in (around 30.000) but also because of the areas represented in, its high taxonomic diversity and finally, because it holds good series of unique species. The collections house representative material of all main mammal orders, being rodents and bats particularly well illustrated. The geographic areas covered by the collections are: Palaearctic (mainly Spain, Portugal, Morocco, Western Sahara), Aethiopic (Cameroon, Equatorial Guinea, Islands of the Gulf of Guinea , Angola, Gabon and Ehiopia), Neotropics (Argentina, Paraguay, Bolivia, Ecuador, Venezuela, Panama, Nicaragua, Mexico), and Southeast Asia (Laos, Thailand, Malaysia). Finally, of exceptional importance are the holdings of extremely rare species such as the Iberian lynx. This is a unique series in the world that give a unique character to the collections of the EBD. The collection of bats of Estación Biológica de Doñana is an important subset of the EBD Mammal Collection. The bat dataset is especially interesting by its specific diversity, comprises approximately 7,600 specimens representing 285 species belonging to 15 out of the 18 families recognized nowadays within Chiroptera. Particularly, the bat collection of the Gulf of Guinea includes approximately 2,000 specimens belonging to 64 species. The geographical area covered by this collection is the group of Islands of the Gulf of Guinea (Bioko, Sao Tome and Principe and Annobon). This collection is particularly interesting for different reasons. First of all, because of the area covered; in fact the group of islands of the Gulf of Guinea is considered as a world diversity hot-spot with 60% of their vertebrate fauna endemic at specific or subspecific level. Secondly, because of its representation. In fact, the collection is the result of several year surveys all over the different habitats of the Islands by a group of researchers from the EBD. This collection has been thoroughly studied at morphological and molecular levels in a PhD work. As a result, the systematics and taxonomy of the different groups considered are well updated and several new taxa have been described from this material. All types are deposited in this collection.

It has been rescued by ① extracting it from the GBIF.org index (see GBIF Download in External Data) and ② republishing it on this IPT data hosting centre as version 1.0.
