Potential Analysis for Further Nature Conservation in Azerbaijan: A Spatial and Political Investment Strategy
Financed by the MAVA Foundation (Switzerland), the Michael Succow Foundation (MSF), in cooperation with various experts from Azerbaijan, conducted a detailed gap analysis of potential future protected areas in Azerbaijan. This report presents the results of this project and constitutes a part of the strategy of the MSF: to provide sound background information on the biological value and its further potential for protection in Azerbaijan. From the very beginning of the foundation’s engagement in Azerbaijan nine years ago, the sciencebased protection of landscapes and species has been the main focus of our work in the country.researc
GrassPlot v. 2.00 – first update on the database of multi-scale plant diversity in Palaearctic grasslands
Abstract: GrassPlot is a collaborative vegetation-plot database organised by the Eurasian Dry Grassland Group (EDGG) and listed in the Global Index of Vegetation-Plot Databases (GIVD ID EU-00-003). Following a previous Long Database Report (Dengler et al. 2018, Phyto- coenologia 48, 331–347), we provide here the first update on content and functionality of GrassPlot. The current version (GrassPlot v. 2.00) contains a total of 190,673 plots of different grain sizes across 28,171 independent plots, with 4,654 nested-plot series including at least four grain sizes. The database has improved its content as well as its functionality, including addition and harmonization of header data (land use, information on nestedness, structure and ecology) and preparation of species composition data. Currently, GrassPlot data are intensively used for broad-scale analyses of different aspects of alpha and beta diversity in grassland ecosystems
Mires of Azerbaijan
Abstract:
The mires of the eastern Caucasus on the territory of Azerbaijan were investigated since 2005. Due to the semihumid to semiarid climate the area of mires does not exceed 1 % of the total territory of the country. In the mountains surface flow mires and terrestrialisation mires have been found. In the lowlands a few surface flow mires and degraded water rise mires are scattered and are threatened by drainage.Zusammenfassung:
Die Moore des östlichen Kaukasus innerhalb des Territoriums von Aserbaidschan wurden seit 2005 untersucht. Der Anteil der Moore an der Landesfläche liegt aufgrund seines semihumiden bis semiariden Klimas unter 1 %. In den Bergregionen dominieren Überrieselungs- und Verlandungsmoore, in den Flachländern sind vereinzelt Überrieselungs- und degradierte Versumpfungsmoore zu finden. Letztere sind in ihrer Existenz stark bedroht.DFG, SUB Göttingen, DGMTresearc
Figure S8 Influence CE position EIS
Figure S8: A) Influence of the position of the counter electrode on EIS curves recorded with the Pt wire CE as working electrode and the GDE as counter electrode @OCV. B) Influence of the position of the counter electrode on EIS curves recorded with the GDE as working electrode @-250 mA cm-2geo in oxygen atmosphere. C) iR drop between RE and GDE determined out of the EIS spectra shown in C)

Figure S10: : A) Influence of the electrolyte temperature on EIS curves recorded @OCV. B) iR drop determined by fitting the EIS spectra shown in A)
Figure 3 Comparison iR correction technique
Figure 3: Comparison of different iR-correction techniques for post-measurement processing of recorded ORR-activity data. A) Temperature evolution of the cell electrolyte during the polarization curve measurement when adding EIS and CI for post measurement determination of the iR drop. B) iR drop depending on the current density measured via EIS and CI. C) Overall polarization curves with different iR corrections. The red point shows a single point measurement, where EIS was carried out before and after the potential measurement and is used to give the standard deviation due to the temperature related change of iR drop during the measurement time of this single point. Measurements were carried out on GDEs with a Pt loading of 100 µg cm.2
Figure S4 CV curves in O2 variation electrolyte concentration
Figure S4: Influence of the electrolyte concentration on CV curves in O2, relating to a HClO4-concentration-dependent limiting current.
