[Methods] This dataset is for 50 Bale long-eared bats, Plecotus balensis, captured in five moutnain ranges in Ethiopia 2014-2015 and genotyped for 19 polymorphic autosomal microsatellite loci previously developed for the genus (Razgour et al., 2013, Ecology Letters, https://doi.org/10.1111/ele.12158) and two mitochondrial DNA regions: 650 bp fragment of the gene cytochrome b (cytb) and 460 bp fragment of the hyper-variable region (HV1) of the control region. The microsatellite dataset is presented as genepop file. Sequence assembly of the concatenated cytochrome b and hyper-variable I region of the mitochondrial DNA is presented as .fasta file. The dataset also includes output of the Maxent species distribution models and STRUCTURE (Bayesian individual-based assignment tests) outputs., Whilst climate change is recognised as a major future threat to biodiversity, most species are currently threatened by extensive human-induced habitat loss, fragmentation and degradation. Tropical high altitude alpine and montane forest ecosystems and their biodiversity are particularly sensitive to temperature increases under climate change, but they are also subject to accelerated pressures from land conversion and degradation due to a growing human population. We studied the combined effects of anthropogenic land-use change, past and future climate changes and mountain range isolation on the endemic Ethiopian Highlands long-eared bat, Plecotus balensis, an understudied bat that is restricted to the remnant natural high altitude Afroalpine and Afromontane habitats. We integrated ecological niche modelling, landscape genetics and model-based inference to assess the genetic, geographic and demographic impacts of past and recent environmental changes. We show that mountain range isolation and historic climates shaped population structure and patterns of genetic variation, but recent anthropogenic land-use change and habitat degradation are associated with a severe population decline and loss of genetic diversity. Models predict that the suitable niche of this bat has been progressively shrinking since the last glaciation period. This study highlights threats to Afroalpine and Afromontane biodiversity, squeezed to higher altitudes under climate change while losing genetic diversity and suffering population declines due to anthropogenic land-use change. We conclude that the conservation of tropical montane biodiversity requires a holistic approach, using genetic, ecological and geographic information to understand the effects of environmental changes across temporal scales and simultaneously addressing the impacts of multiple threats., British Ecological Society, Award: 4849/5889.

ESTACIÓN BIOLÓGICA DE DOÑANA - CSIC, ANFIBIOS

  • Juste, Javier
The Anphibian collections of Doñana Biological Station (EBD) were first established with the donation of the private collections of Prof. JA Valverde, a prominent Spanish zoologist and founder of the Doñana Institution itself. These collections not only presented all mainly species of the Iberian peninsula but also representatives from the fauna of the former Spanish colonies in North Africa and Western Sahara. The collections grew exponentially with the following director, Prof. Javier Castroviejo who was responsible of its enlargement and enormous expansion both in individuals and in localities represented. At present these collections hold above 15.000 specimens belonging to 150 species of about 20 families; most of them well preserved in fluid (ethanol 80%) and with complete information about origin and measurements. Amphibian holdings of the EBD collections come mainly from the Iberian peninsula but also from North Africa, Western Sahara and in lesser extent from other European areas such as Hungary and Italy. Besides, there is an important representation both from African (e.g. Equatorial Guinea) and American (Venezuela, México, Paraguay, Nicaragua and Bolivia) tropical ecosystems. Particularly well represented are remote and poorly known South American areas such as swamp savannahs (Mato Grosso), Tepui table-top mountains and high mist-rainforest of the central Andes (Bolivia) From a systematic point of view, EBD Anphibian holdings have good representations of the families Discoglossidae, Hylidae and Ranidae from Southwestern Iberia and excellent sampling of salamanders from the Cantabrian mountain range. Regarding the African continent, the families Ranidae, Pipidae and Hylidae are quite well represented as well as the neotropical families Bufonidae, Hylidae, Leptodactilidae, Aromobatidae and Dendrobatidae (Boliivia and Paraguay), and Centrolinidae, Leptodactiylidae, Pletodontidae and Microhylidae (Venezuela). Nowadays the complete data set regarding the EBD Amphibian collections is being screened and computerized. In a near future the whole information will be world-wide available through the GBIF free access portal. The dataset currently available on GBIF.ES is one part of the mammal collection, and include the following families: Salamantridae, sirenidae, proteidae, Amphiumidae, Ambystomatidae, Plethodontidae, Gymnophiona, anphibia, anura, caudata, Hylidae, Pipidae, Aromabatidae, Caeciliidae, Cycloramphidae. Note: this dataset was previously orphaned. 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.

ESTACIÓN BIOLÓGICA DE DOÑANA - CSIC, MAMMAL COLLECTION

  • Juste, Javier
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. The dataset currently available on GBIF.ES is one part of the mammal collection, and include the following orders and families: Orden Chiroptera: Familia Pteropodidae Familia Rhinolophidae Familia Hipposideridae Familia Phyllostomidae; Familia Molossidae; Familia Noctilionidae, Familia Emballonuridae, Familia Vespertilionidae, Familia Rhinopomatidae, Familia Natalidae, Familia Thyropteridae, Familia Nycteridae, Familia Mormoopidae, Familia Furipteridae; Orden Erinaceomorpha: Familia Erinaceidae; Orden Soricomorpha: Familia Talpidae Familia Soricidae;, Orden Afrosoricida: Familia Tenrecidae; Orden Rodentia: Suborden Sciuromorpha, Familia Gliridae Familia Sciuridae Subfamilia Sciurinae, Subfamilia Xerinae, Subfamilia Callosciurinae; Suborden Myomorpha , Familia Dipodidae Familia Muridae: Subfamilia Murinae Subfamilia Gerbillinae, Subfamilia Deomynae, Familia Cricetidae: Subfamilia Arvicolinae Subfamilia Cricetinae Subfamilia Sigmodontinae, Subfamilia Neotominae, Familia Nesomyidae, Suborden Anomaluromorpha Familia Anomalurinae, Suborden Hystricomorpha, Familia Ctenodactylidae, Familia Caviidae: Subfamilia Hydrochaerinae, Subfamilia Dolichontinae; Familia Hystricidae, Familia Thryonomyidae, Familia Erethizontidae, Familia Chinchillidae, Familia Dasyproctidae, Familia Cuniculidae, Familia Ctenomyidae, Familia Octodontidae, Familia Echimyidae, Familia Myocastoridae; Orden Lagomorpha, Familia Leporidae; Orden Carnivora, Suborden Caniformia, Familia Mustelidae, Subfamilia Mustelinae, Subfamilia Lutrinae, Familia Mephitidae, Familia Procionidae, Familia Ailuridae, Familia Canidae; Orden Macroscelidea: Familia Macroscelididae ; Orden Artiodactyla: Familia Bovidae Subfamilia Cephalophinae Palabras clave: Mammals, Bats, Chyroptera, Equatorial Guinea, Rodentia, Lagomorpha Note: this dataset was previously orphaned.
