Data from: The microbially-mediated soil organic carbon loss under degenerative succession in an alpine meadow
Land-cover change has long been recognized as having marked effect on the amount of soil organic carbon (SOC). However, the microbially-mediated processes and mechanisms on SOC are still unclear. In this study, the soil samples in a degenerative succession from alpine meadow to alpine steppe meadow in the Qinghai-Tibetan Plateau were analyzed using high-throughput technologies, including Illumina sequencing and GeoChip functional gene arrays. The soil microbial community structure and diversity were significantly (P < 0.05) different between alpine meadow and alpine steppe meadow, the microbial ɑ-diversity in alpine steppe meadow was significantly (P < 0.01) higher than in alpine meadow. Molecular ecological network analysis indicated that the microbial community structure in alpine steppe meadow was more complex and tighter than in the alpine meadow. The relative abundance of soil microbial labile carbon degradation genes (e.g., pectin and hemicellulose) was significantly higher in alpine steppe meadow than in alpine meadow, but the relative abundance of soil recalcitrant carbon degradation genes (e.g. chitin and lignin) showed the opposite tendency. The Biolog Ecoplate experiment showed that microbially-mediated soil carbon utilization was more active in alpine steppe meadow than in alpine meadow. Consequently, more soil labile carbon might be decomposed in alpine steppe meadow than in alpine meadow. Therefore, the degenerative succession of alpine meadow because of climate change or anthropogenic activities would most likely decreased SOC and nutrients medicated by changing soil microbial community structure and their functional potentials for carbon decomposition.

Effects of temperature treatments on cytosine-methylation profiles of diploid and tetraploid plants of the alpine species Ranunculus kuepferi (Ranunculaceae)
<p>The current dataset refers to the DNA methylation patterns of diploid and tetraploid individuals of <em>Ranunculus kuepferi</em>, obtained with the method of methylation-sensitive AFLPs (MS-AFLPs).</p> <p>The individuals of Ranunculus kuepferi were collected from several locations throughout the distribution of the species in the Alps, transferred to the old Botanical Garden of Göttingen and placed into two climate chambers MC1000E (Snijders Scientific, Tilburg, Netherlands), where the temperature treatment experiments took place. In the first chamber a cold treatment was applied (+7°C day/+2°C night; frost treatment: -1°C cold shocks for three nights per week), while in the second chamber a warm treatment was applied (+15° day/+10°C night).</p> <p>The plants were shifted from one treatment to the other one after the end of the 2016 flowering period and leaf material was collected during the flowering period of 2016 and 2017. This material went through the respective lab procedures in order to obtain the genome-wide patterns of epigenetic variation via MS-AFLPs.</p> <p>The analysis of the electropherograms was conducted with Peakscanner v.2 and fragment scoring was performed with RawGeno 2.0-1 R package. These fragment scoring binary matrices are presented here.</p>

The code file also contains the description of the data files, code for data management, code for figures and additional analyses. The Appendix (appendix.pdf) is a pdf.</p> <p><strong>Abstract of the article</strong></p> <p>Alpine black grouse populations are generally declining, but the underlying demographic drivers are largely unknown. We studied the dynamics of two adjacent black grouse populations over a 20 years period in the Italian Alps that differ in hunting pressure to identify the main demographic process affecting these populations and to study the impact of hunting on males. We collected radio-tracking data and conducted population surveys in spring to count displaying cocks and in late summer to determine the breeding success by means of pointing dogs. These different data sets were jointly analysed using a seasonal integrated population model to estimate population sizes and various demographic rates. The two populations fluctuated in size and the number of males from one population increased after hunting intensity was reduced. The main demographic rates did not differ between the populations. Adult survival was relatively low and productivity was high, so the life history shows the feature of a fast turnover species. In both populations, the variability of survival from hatching to the age of five weeks (chick survival) contributed more to the variation of the population growth rates than the variability of survival in later life-history stages, and the former was positively affected by ambient temperatures in July, favouring chick survival. The adult sex ratio of the population where males hunting occurred was shifted towards females, but it evened over time with the reduction of hunting pressure. The adult sex ratio in the population without hunting and the chick sex ratios in both populations were even, suggesting that hunting acted as a mostly additive source of mortality.</p>
Bird species co-occurrence patterns in an Alpine environment supports the stress gradient hypothesis
<p>Understanding the relative contribution of different biotic interactions in shaping species assemblages constitutes a major goal in community ecology and consequently, multiple methods aimed at inferring the nature of these associations have emerged during the last decade. In this framework, the stress-gradient hypothesis (SGH) predicts that prevalent biotic interactions shift from competition to facilitation as abiotic stress increases (and productivity decreases). This hypothesis originally raised by plant ecologists has been barely applied to faunal communities. Here, we take advantage of 20 years of abundance data to investigate pairwise patterns in species co-occurrence in Alpine bird communities inhabiting two contrasting habitat types; forests (high-productivity) and mountain grasslands (low-productivity). We also integrate functional data with presence-absence and quantitative matrices in order to detect the signature of processes driving community assembly and test for limiting similarity. We employed a Bayesian approach, probabilistic pairwise association tests and joint Species Distribution Models; all methods revealed a higher frequency of positive interactions in mountain grasslands in agreement with what the SGH predicts. Both the frequency of positive and negative interactions remained moderately stable over the study period in both habitat types. There was no significant relationship between the degree of co-occurrence of species pairs and their functional distance in either habitat. However, when we only considered those combinations of species whose co-occurrence pattern deviated from that expected at random, we found that co-existing species are functionally more similar than those pairs that show segregated patterns in the forest assemblages. Such a relationship may arise via selective social information use and other processes including microhabitat preferences. Overall, our findings suggest that interspecific competition does not seem to be a major force driving the structure of bird assemblages in this mountain region.</p>
