FIGURE 6 in A new, high-elevation glassfrog (Anura: Centrolenidae) from Manu National Park, southern Peru
FIGURE 6. Distribution of the seven species of Centrolene known to occur in Peru. Six of the seven species are only known from their type locality, shown on this map. The only species with a type locality outside of Peru is C. buckleyi, and the locality reported here is for specimen KU 181884 (Duellman & Wild 1993). Centrolene lemniscatum and C. muelleri are the only two species known to occur sympatrically in Peru. The generic placement of Centrolene azulae and C. fernandoi is uncertain (Guayasamin et al. 2009).

Data for: Interplay of abiotic conditions, density, and body size in shaping demography in a high-elevation toad population
<p>This dataset is used to estimate vital rates of a common toad (<em>Bufo bufo</em>) alpine population, and how they are associated with either abiotic (environmental conditions), biotic (in our case population size), and individual factors (body size). We have individual capture histories for the period 1993-2020 for 1615 males and 933 females, as well as body size measurements taken during capture events. For more info about the study system see: https://peercommunityjournal.org/articles/10.24072/pcjournal.240/</p> <p>We run a capture-mark-recapture model coupled with a growth model, the latter to obtain information on body size for the years when the individuals were not captured. Aside from sex-specific survival, we estimate female breeding probability, since they show intermittent breeding. We include as covariates for these vital rates the length of the active season, the temperature at emergence from hibernation, population size, and body size. </p> <p>We obtained climatic data for the period 1980–2020 from the DaymetCH dataset (data obtained from Bioclimatic maps of Switzerland © WSL, based on station data from the Federal Office of Meteorology and Climatology MeteoSwiss, and elaborated by the Land Change Science group, WSL).</p> <p>The README file further describes each uploaded file</p>

Dataset for: Relative contribution of high and low elevation soil microbes and nematodes to ecosystem functioning
<ol> <li><span>Ecosystem productivity is largely dependent on soil nutrient cycling which, in turn, is driven by decomposition rates governed by locally-adapted belowground microbial and invertebrate communities. How climate change will impact soil biota and the correlated ecosystem functioning, however, remains largely an open question.</span></li> <li><span>To address this challenge, we first characterized the functional identity of soil microbial and nematode communities originated from the foothills or in the sub-alpine soils of the Alps, and then, using a full-factorial reciprocal transplant common garden experiment at two elevations, we asked whether soil biota from low elevation were more prone in generating nutrient cycling than high elevation soil biota. Specifically, we separately transplanted soil microbial and nematode to community from low and high elevation in their home or opposite elevation in pots added with a common plant community. </span></li> <li><span>We found evidence for ecotypic and functional differentiation of the microbial and nematode communities growing in. We also observed a decrease in microbial diversity and activity at high elevation, and additionally, through nematodes' functional characterization, we found increased fungal-dominated energy channels at high elevation. </span></li> <li><span>Moreover, while we found little effect of soil biodiversity change based on elevation of origin on plant productivity, soils inoculated with microbes originating from low elevation respired more than those originating at high elevation. This observation correlates well with the observed faster carbon degradation rates by the low-elevation microbial communities. </span></li> <li><span>Climate change can reshuffle soil invertebrate communities depending on organism-specific variation in range expansion, ultimately affecting soil fertility and vegetation productivity.</span></li> </ol>
Data from: Nectar robbing rather than pollinator availability constrains reproduction of a bee-flowered plant at high elevations
<p>The files contain data on the floral ecology of <em>Clinopodium alpinum</em> collected along an elevational gradient in the Berchtesgaden National Park in Germany in 2017. The data are presented in the work entitled "Nectar robbing rather than pollinator availability constrains reproduction of a bee-flowered plant at high elevations" by Patrick L. Kohl and Ingolf Steffan-Dewenter. Files include data on flower visitor observations (including raw data on the number of visits by individual specifmens), data on seed/ovule ratios (both open pollinated and bagged flowers), data on the incidence of nectar robbing by bumble bees (the frequency of corolla perforations) and of flower herbivory by Eulophidae, and data on basic flowering traits of <em>C. alpinum</em> (number of flowers per inflorescence, corolla tube length, display size).</p>
Let it snow? Spring snowpack and microsite characterize the regeneration niche of high-elevation pines
<p><b>Aim: </b>The persistence potential of forests under rapid climate change will depend on species-specific tolerances to increasing growing season soil moisture stress as snowpack declines. High-elevation tree species may be particularly vulnerable to increasing water stress and associated changes to disturbance regimes because they occur at the environmental margins of tree distributions and are considered snowpack dependent. Here, we evaluate the interacting effects of climate, disturbance, and microsite conditions on tree regeneration in high-elevation, migration-limited pines that have experienced recent disturbance-induced tree mortality.</p> <p><b>Location</b>: Great Basin (California & Nevada), USA</p> <p><b>Taxon: </b>Gymnosperms; Pinaceae</p> <p><b>Methods:</b> We used field observations from 70 sites that varied in climate, disturbance, and local site conditions across semi-arid, high-elevation forests of the Great Basin. We employed structural equation models to evaluate how climate and disturbance interact with microsite conditions to influence regeneration.</p> <p><b>Results: </b>We found a broad range of establishment conditions of high-elevation conifers - whitebark, limber, and bristlecone pines – across climatic and disturbance gradients in the Great Basin, but our research detected clear differences in the regeneration niche for each species that may lead to differential survival as climate and disturbance conditions continue to change. Regeneration of whitebark and bristlecone pines diverged in their responses to spring snowpack conditions, with whitebark pine increasing and bristlecone pine decreasing with greater spring snowpack. Limber pine regenerated across a range of climatic and landscape conditions, and this generalist strategy may be advantageous if future climate and disturbance conditions exceed tolerances of more specialized species.</p> <p><b>Main Conclusions: </b>Our findings highlight the critical role that spring snowpack, and consequently growing season soil moisture, plays in determining the persistence potential of high-elevation conifers. However, this role varies among species and thus may drive compositional changes as earlier snowmelt drives soil moisture declines across mountainous landscapes of the western United States.</p>
