Specific Species

A native Iranian plant, Nepeta menthoides, located and distributed in the north west of Iran, is a gramineous, perennial plant species which belong s to mint family. Highlands of Sabalan Mountain, in Ardebil province, Shabil and Gotur Suyi regions are habitats for this specific species. This study enjoys samples collected from selective habitats in the stage of 50% flowering; moreover, the collected samples were dried in an appropriate and standard condition. Abooreyhan laboratory of Jungle and Pasture research institute was the place in which the above mentioned samples have undergone the process of essential oils, using the water steam method of distillation. The extracted components were gauged and identified by means of gas chromatography system connected to mass spectrograph. The results of the study distinctly indicated that in the habitat condition, the species grows in the highlands of Sabalan Mountain over the attitude of 3200 to 4000 meters, this specific species is highly visible in series and sandy clay hills, it is demonstrated that the density of the species has been increased as the height was increasing. Essential oil in the investigated area was ranging from 1.6% to 2.40%, admittedly, the least amount was in Gotur Suyi, while, the highest amount belonged to Shabil. Nineteen  chemical compounds were identified in samples collected from natural habitats, amongst all, the highest proportion belongs to 8,10-Cineole and Citronellol acetate.8,10- Cineole was ranging from 33 to 34 percent, the least amount was identified in Gotur Suyi region (before hot water spa) and the highest amount was observed between Gotur Suyi and Shabil. As mentioned earlier, Citronellol acetate was the second chemical compound, which was ranging from 16% to 31% and the least and the highest amount were known in Gotur suyi and Shabil, respectively. Samian medicinal plants research station possesses the highest level with the value of 57%.

<p>Soil microbiota ensuring sustainable functioning of terrestrial ecosystems is strongly dependent on climatic conditions and vegetation type. Even within the same climatic zone, active land use alters the size, structure and functioning of the microbial community. We hypothesized that land use effect on soil microbial biomass will be more pronounced under impact of global warming. We also tested whether the biomass of specific microbial group (e.g., fungi) is more sensitive to environmental changes than total microbial biomass.</p><p>We proved these hypotheses in the experiments based on Global Change Experimental Facility platform, located at the field research station of the Helmholtz-Centre for Environmental Research in Bad Lauchstädt near Halle, Saxon-Anhalt, Germany. Experimental setup included 50 plots, located in 10 blocks (5 plots per block). Five blocks are under ambient climate and the rest 5 blocks are subjected to a realistic climate change treatment (under conditions predicted by several models of climate change in Central Germany for 2050–2080 period). Five land use types were established in every block: conventional farming; organic farming; intensively used meadow, extensively used meadow and extensively used pasture. We determined soil microbial biomass and its fungal component by chloroform fumigation-extraction method and by ergosterol content, respectively. We found that fungal biomass was more sensitive to intensive land use for crop production than to climate change. The possible mechanisms of such a sensitivity will be discussed.</p>

Sakaerat Biosphere Reserve is one of the four Biosphere Reserves in Thailand. It is situated at Khorat Plateau and comprises of mainly dry evergreen forest and dry dipterocarp forest. Despite studies that document its rich biodiversity, there was no concerted study on the orthopteran diversity. Recent sampling by the authors in Sakaerat led to the discovery of numerous undescribed species. A checklist, first for the place, is also reported here, each species represented with a habitus photograph. In total, 128 species of Orthoptera from 11 families were recorded. Caelifera (grasshoppers) were represented with five families and Ensifera (crickets and katydids) were represented with six families, making up 10 of the 16 lineages in the orthoptera phylogeny.

Abstract. The period range between 6 and 480 min is known to represent the major part of the gravity wave spectrum driving mesospheric dynamics. We present a method using wavelet analysis to calculate gravity wave activity with a high period resolution and apply it to temperature data acquired with the OH* airglow spectrometers called GRIPS (GRound-based Infrared P-branch Spectrometer) within the framework of the NDMC (Network for the Detection of Mesospheric Change; https://ndmc.dlr.de, last access: 22 September 2020). We analyse data measured at the NDMC sites Abastumani in Georgia (ABA; 41.75∘ N, 42.82∘ E), ALOMAR (Arctic Lidar Observatory for Middle Atmosphere Research) in Norway (ALR; 69.28∘ N, 16.01∘ E), Neumayer Station III in the Antarctic (NEU; 70.67∘ S, 8.27∘ W), Observatoire de Haute-Provence in France (OHP; 43.93∘ N, 5.71∘ E), Oberpfaffenhofen in Germany (OPN; 48.09∘ N, 11.28∘ E), Sonnblick in Austria (SBO; 47.05∘ N, 12.95∘ E), Tel Aviv in Israel (TAV; 32.11∘ N, 34.80∘ E), and the Environmental Research Station Schneefernerhaus on top of Zugspitze mountain in Germany (UFS; 47.42∘ N, 10.98∘ E). All eight instruments are identical in construction and deliver consistent and comparable data sets. For periods shorter than 60 min, gravity wave activity is found to be relatively low and hardly shows any seasonal variability on the timescale of months. We find a semi-annual cycle with maxima during winter and summer for gravity waves with periods longer than 60 min, which gradually develops into an annual cycle with a winter maximum for longer periods. The transition from a semi-annual pattern to a primarily annual pattern starts around a gravity wave period of 200 min. Although there are indications of enhanced gravity wave sources above mountainous terrain, the overall pattern of gravity wave activity does not differ significantly for the abovementioned observation sites. Thus, large-scale mechanisms such as stratospheric wind filtering seem to dominate the evolution of mesospheric gravity wave activity.

Within the CO2 time series measured at the Environmental Research Station Schneefernerhaus (UFS), Germany, as part of the Global Atmospheric Watch (GAW) program, pollution episodes are traced back to local and regional emissions, identified by δ13C(CO2) as well as ratios of CO and CH4 to CO2 mixing ratios. Seven episodes of sudden enhancements in the tropospheric CO2 mixing ratio are identified in the measurements of mixing/isotopic ratios during five winter months from October 2012 to February 2013. The short-term CO2 variations are closely correlated with changes in CO and CH4 mixing ratios, achieving mean values of 6.0 ± 0.2 ppb/ppm for CO/CO2 and 6.0 ± 0.1 ppb/ppm for CH4/CO2. The estimated isotopic signature of CO2 sources (δs) ranges between −35‰ and −24‰, with higher values indicating contributions from coal combustion or wood burning, and lower values being the result of natural gas or gasoline. Moving Keeling plots with site-specific data selection criteria are applied to detect these pollution events. Furthermore, the HYSPLIT trajectory model is utilized to identify the trajectories during periods with CO2 peak events. Short trajectories are found covering Western and Central Europe, while clean air masses flow from the Atlantic Ocean and the Arctic Ocean.

<p>Education is key in order to create a generation that thinks and acts sustainable and that considers nature as one of the most important good.Within the three years Interreg Project ‘KlimaAlps’ (www.klimaalps.eu) – making climate change visible - one major task is the establishment of a training for educators, to become a certified ‘Climate-Pedagogue’ for the alpine region. The ‘Climate-Pedagogue’-training contains background information of climate change in the Alps and a variety of innovative educational tools and methods. It covers aspects of the high mountain areas, rivers and lakes, human beings, agriculture as well as moors.  The project is managed by the ‘Energiewende Oberland’; five additional partners from Austria and Bavaria are responsible for e. g. a high quality of the taught scientific information (Environmental Research Station Schneefernerhaus), the didactical input (University of Innsbruck, Department of Geography), the outreach activities and the implementation (Naturpark Karwendel, Klimabündnis Oberösterreich, Landratsamt Garmisch-Partenkirchen). During the last one and half years, the concept for the ‘Climate-Pedagogue’- training was worked out in cooperation with other environmental facilities and in March 2021 the first lectures of a pilot run with over 30 selected participants were held. In total there will be two runs in 2021 in order to evaluate the recent version of the training as good as possible. The next and long-term steps will be the firm establishment of a chargeable ‘Climate-Pedagogue’ – Training for every interested person for at least the coming ten years, as well as the strengthening and growing of the network. The presentation will give a short overview about the entire project as well as details about the ‘Climate-Pedagogue’ – Training and some first impressions of the already hold lectures in 2021.</p>

<p>The Environmental Research Station Schneefernerhaus (UFS) is Germany’s highest research station, located at an altitude of 2650 m. For over 20 years, many different institutions have been working here on a variety of permanent studies on an inter- and trans-disciplinary basis. Eight key scientific activities were assigned in 2007. These are:</p><ul><li>Satellite-based observations and early detection</li> <li>Regional climate and atmosphere</li> <li>Cosmic radiation and radioactivity</li> <li>Hydrology</li> <li>Environmental and high-altitude medicine</li> <li>Global Atmosphere Watch (GAW)</li> <li>Biosphere and Geosphere</li> <li>Cloud dynamics</li> </ul><p>Beyond these permanent research activities, around 80 temporary projects have been conducted with over 13 international partners. Over 30 projects are currently running at the UFS. The ‘size’ of the projects varies from small research groups and very short-term studies, to large research consortiums and long-term projects. The UFS is, furthermore, a partner in a number of international networks of (mountain) observatories, such as the Global Atmosphere Watch program of the WMO. International exchange is therefore guaranteed.</p><p>The operating company of the UFS makes the high quality of research possible. It takes care of the needs of the researchers, such as logistics, data transfer and exchange, and outreach. The UFS also serves as a meeting and educational center for research teams, operators of other stations and early- career scientists. The UFS is easily accessible all year round: a train line runs up the mountain, directly into the UFS building and allows the transportation of heavy material and devices. A well-equipped workshop allows the in-situ repair of instruments.</p><p>Beside some general information about the UFS, the presentation will highlight some recent projects in which the UFS has been involved. It will also show how to use the UFS for your own research ideas.</p>

Abstract. Darkening of pristine white areas on Earth could happen when light absorbing particles are deposited on snow and ice surfaces. Airborne particles like mineral dust, ashes or carbonaceous aerosols are able to reduce the snow and ice albedo already by a small quantity of deposited particles. In this study we developed a laboratory analysis method to address mass and absorption properties of snow particles simultaneously. For a set of snow samples, taken at the Environmental Research Station Schneefernerhaus (UFS) during winter 2016/2017, we combine the determination of refractory Black Carbon mass (rBC) by a Single Particle Soot Photometer (SP2) with photo acoustic aerosol absorption spectroscopy at three distinct wavelengths across the visible spectral range (PAAS-3λ). For the calibration of the method, Fullerene standard aerosol was used and its mass specific absorption cross section was determined. The analysis of the UFS snow sample measurements reveals a significant difference between the particle masses determined from the PAAS-3λ and the SP2 data. Our findings suggest that the light absorbing particles included in the snow could not only be composed of rBC but must have particulate matter of different nature. This result is confirmed by Environmental Scanning Electron Microscopy (ESEM) and single particle fluorescence measurements with the Waveband Integrated Bioaerosol Sensor (WIBS-4) which both revealed a significant portion of biological material to be present in the snow samples.
