Description: Alpine pastureland is increasingly abandoned, leading to shrub encroachment and to the accumulation of low-quality litter. Alpine key decomposers such as earthworms were found to feed on both low- and high-quality litter, but little is known how this might affect their life history traits. To fill this gap of knowledge, we conducted a laboratory experiment with the widespread earthworm species Lumbricus rubellus Hoffmeister, 1843. Hatchlings were provided with either of three aged litter types: grass and forb leaf litter as high-quality food sources and dwarf shrub leaves as low-quality food source. A control group was fed with aged cow dung. Biomass, days until (pre-)maturity, mortality, and reproduction rate were measured regularly to assess the impacts of food quality on earthworm development. We found pronounced impacts of food source quality on the fitness of L. rubellus. The low-quality litter led to significantly delayed development of up to 53 days, the lowest mean biomass (720 mg after 32 weeks) as well as a 50% drop of produced cocoons compared with the high-quality litter. However, the F2 generation showed the highest hatchling success in the shrub treatment. We conclude that the increased consumption of low-quality dwarf shrub litter led to negative effects on the development and reproduction of L. rubellus. Overall, this might be the main reason for declining earthworm densities in abandoned Alpine pasture soils, even though the biomass of the second generation was not significantly affected possibly due to a phenotypic variability in reproduction strategy. However, the decrease of such important decomposers and ecosystem engineers can have far reaching consequences for ecosystem processes such as litter accumulation and bioturbation and thus for the stability of Alpine soil ecosystems.

Description: Here, we present abundance data from 20 soil macro-invertebrate groups from 22 different natural to artificial habitat types in the European Alps. The dataset contains data obtained from soil macro-invertebrate samples (i.e., soil blocks) collected between 1987 and 2020, with the majority of them already published individually in scientific journals. The purpose of this work is to collate the single datasets on Alpine soil macro-invertebrates to one uniform dataset, as such data is only sparsely available. We also want to appreciate the scientific lifework of our mentor and friend, the soil ecologist/soil zoologist Erwin Meyer (1948–2020). The samplings were mainly conducted by Erwin Meyer and his students at the University of Innsbruck (Austria) and Eurac Research (Italy). The assessments of the soil macro-invertebrate communities were part of several sampling campaigns including scientific projects, as well as diploma, master and doctoral theses. The sampling took place mainly during the vegetation period from April to October; in the alpine zone where snow can persist for a long time from June to September. The samples were taken in the following Alpine regions: Vorarlberg and Tirol (Austria), South Tyrol and Trentino (Italy), and the Canton of Uri (Switzerland). The abundance data is given as individuals per square metre (ind./m²) on order level (and species level in case of earthworms). Each row represents one single soil fauna sample. The event code (i.e., representing the different sampling plots) is composed of the sampling region (three letters capitalised), the habitat or plot code (three letters) and the replicate number of these plots (consecutive numbers). Additionally, to the soil fauna data, we present topographic data (elevation, exposition, inclination) as well as habitat classification (e.g., CORINE Land Cover (CLC) nomenclature code) and description.

Description: In this study, litter decomposition patterns, non-additive effects, and spectral data of abundant alpine leaf litters were assessed in litterbag experiments containing single species and mixtures. We tested if low-quality shrub litter decomposes faster in mixtures with high-quality litter and if predictions on decomposed litter using spectral data are feasible. Therefore, we measured chemical and physical traits and near-infrared reflectance (NIR) spectra of six alpine freshly fallen litter types. A litterbag experiments (0.1 mm mesh size) with single and 2- and 3-species mixtures was conducted with three species from three functional groups (shrub, grass, forb). Decomposition rates, litter mass loss, non-additive effects, total carbon and nitrogen content, and NIR spectra were recorded after 6, 12 and 24 months (the latter are not shown). The six freshly fallen litter types showed significantly differences in leaf litter traits and NIR spectra. Decomposition rates steadily slowed during the 24 months, with shrub litter having the lowest on all sampling dates. In litter mixtures, shrub and grass litter showed higher decomposition rates after 12 and 24 months compared with the single-species treatments.

Description: Interspecific variation in life-history traits and physiological limits can be linked to the environmental conditions species experience, including climatic conditions. As alpine environments are particularly vulnerable under climate change, we focus on the montane-alpine fly Drosophila nigrosparsa . Here, we characterized some of its life-history traits and physiological limits and compared these with those of other drosophilids, namely Drosophila hydei , Drosophila melanogaster , and Drosophila obscura . We assayed oviposition rate, longevity, productivity, development time, larval competitiveness, starvation resistance, and heat and cold tolerance. Compared with the other species assayed, D. nigrosparsa is less fecund, relatively long-living, starvation susceptible, cold adapted, and surprisingly well heat adapted. These life-history characteristics provide insights into invertebrate adaptations to alpine conditions which may evolve under ongoing climate change. Life-history traits and physiological limits of the alpine fly Drosophila nigrosparsa were assayed in the laboratory and compared with those of four other Drosophila species. Drosophila nigrosparsa has relatively low fecundity, is long-living, starvation susceptible, cold adapted, and surprisingly heat tolerant.
