  • This dataset gathers the data of the specimens present in the Zoological Collections of the University of Granada (CCZ-UGR) and coming from Sierra Nevada. As a result of the process of adaptation and improvement of the primary data, 10,005 records have been selected out of the 32,120 catalogued, corresponding to 55,292 specimens out of the 136,837 that are currently catalogued. These figures reveal the important representation of the fauna of the Sierra Nevada, approximately one third of the CCZ-UGR.

  • An extended monitoring programme in the Samaria National Park, with semi-quantitative sampling methods to keep track of the relative abundance presence of various classes of the Arthropoda phyllum. Sampling frequency and density varies according to monitored species.

  • Traditionally managed mountain grasslands are declining as a result of abandonment or intensification of management. Based on a common chronosequence approach we investigated species compositions of 16 taxonomic groups on traditionally managed dry pastures, fertilized and irrigated hay meadows, and abandoned grasslands (larch forests). We included faunal above- and below-ground biodiversity as well as species traits (mainly rarity and habitat specificity) in our analyses. The larch forests showed the highest species number (345 species), with slightly less species in pastures (290 species) and much less in hay meadows (163 species). The proportion of rare species was highest in the pastures and lowest in hay meadows. Similar patterns were found for specialist species, i.e. species with a high habitat specificity. After abandonment, larch forests harbor a higher number of pasture species than hay meadows. These overall trends were mainly supported by spiders and vascular plants. Lichens, bryophytes and carabid beetles showed partly contrasting trends. These findings stress the importance to include a wide range of taxonomic groups in conservation studies. All in all, both abandonment and intensification had similar negative impacts on biodiversity in our study, underlining the high conservation value of Inner- Alpine dry pastures.

  • Studies on ecological successions have a long tradition and strongly contributed to the understanding of community assembly, niche theory and ecosystem structure and functionality. Reports on ecological successions are however mostly restricted to one or two taxonomical groups, neglecting the mutual influences and dependencies between multiple taxonomic groups that are the building blocks of multidiverse communities. We introduce the Alpine research platform Ödenwinkel to promote observational and experimental research on the emergence of multidiversity and ecosystem complexity. We established n = 140 permanent plots along the successional gradient of the forefield of the Ödenwinkelkees glacier at the end of Stubachvalley in the Hohe Tauern range (National Park Hohe Tauern, Land Salzburg, Austria). In summer 2019 we completed a first full inventory of biotic and abiotic characteristics of these plots covering the diversity and composition of vascular plants, bryophytes, arthropods and other animals, bacteria and fungi as well as some geomorphologic properties. In this paper we introduce the design of the research platform and show first results on the diversity and composition of vascular plants along the successional gradient. The Ödenwinkel platform will be available as long-term ecological research site where researchers from various disciplines can contribute to accumulate knowledge on ecological successions and on how interactions between various taxonomical groups structure ecological complexity in this alpine environment.
