title: Tab.1: Location, morphometric parameters, and classification of studied lakes

description: This study investigates a variety of lakes of different origin in the Siberian Lena River delta for lake hydrological, hydrochemical, and morpho- metric characteristics. The results are based on in-situ field measurements and subsequent water sample analyses. Significant differences between the characteristics of polygonal ponds, thermokarst and oxbow lakes, and lakes influenced by sea-water are revealed. The differences in hydrochemical char- acteristics are explained by differences in the lakes' specific locations and relief settings, hydrological regimes, and origins.

title: Fire maps 2000-2011, Central Yakutia, Siberia

description: We investigated fire events using the 8-day MOD14A2 MODIS product, at a 1km pixel resolution. (See also "Source data set" link). It was downloaded from http://e4ftl01.cr.usgs.gov/MOLT/MOD14.005/ for the Years 2000 to 2011.All 8-day fire mask composites were combined to produce a single map for each of the time periods from 2000 to 2002, 2003 to 2005, 2006 to 2008 and 2009 to 2011.The FireMap_2000_2011.zip file includes fire maps of individual years, several years and a map of all occurred Fires in the study area during the time period 2001 to 2011 (FireMap_2000-2011.asc) as ascii-files for the study area (WGS84, WGS84, upper left corner: lat 65, long 117.55, lower right corner: lat 61.05, long 131.05.The ascii-files FireMap_20xx-20xx.asc include all fires from the time interval and with the added coordinates for the global coordinate system WGS1984.The occurrence of the fire is coded as follows: 1999 + the integer divided by 15 gives the year while the rest (from the integer division) attributes to the months May to October (0-1 May, 2-3 June, 4-5 July, 6-7 August, 8-9 September, 10-11 October). Example: Fires in August 2002 would be coded as 51 or 52=&gt; 52 div 15 leads 3 or the year 2002 and the rest 7 would be August.

title: Leaf Area Index (LAI) trends from 2000 to 2011, Central Yakutia, Siberia

description: The LAI product used for analysis is the MODIS product for Leaf Area Index - Fraction of Photosynthetically Active Radiation (MOD15A2) (See also the "Source data set" link). We used the MODIS-LAI product from „Reprocessing the MODIS Leaf Area Index products for land surface and climate modelling" with a spatial resolution of about 1 sq. km per grid cell by Hua Yuan et al. (2011).The LAI_grad_monthly.zip file contains the calculated trends of LAI over the eleven year interval for each separate month starting in May 2000 as ascii-files. Coordinates for the global coordinate system WGS84 were added to these files. The LAI_mean_month contains a stack of the LAI mean values just for each month and for each year from 2000 to 2011 as ascii-files. All maps have an extent of upper left corner: lat 65, long 117.55, lower right corner: lat 61.05, long 131.05.

title: Lake maps 2001/2002 and 2009, Central Yakutia, Siberia

description: Lakes were mapped based on Landsat mosaics from 2001/2002 and 2009. Maps are stored as ESRI shapefile. Projection: UTM 52N, Datum: WGS84, Extent: South-bound Latitude: 60.40 * West-bound Longitude: 113.00 * North-bound Latitude: 65.60 * East-bound Longitude: 133.40 Methods: Waterbody mapping was carried out using two mosaics of Landsat satellite images: A Landsat TM mosaic consisting of 25 images acquired during the summer of 2009 and a mosaic of 31 Landsat ETM+ images recorded during two consecutive summers in 2001 (12 images) and 2002 (19 images). Heavy cloud cover in 2001 and 2002 made it necessary to combine remote sensing data from these two years in order to create a cloud free baseline for change detection over the entire region covered by the (cloud-free) 2009 mosaic. The average day of year (DOY) for the 12 images in our 2001 dataset was therefore 213 ±19 (1st August), and for the 19 images in the 2002 dataset 212 ±15 (31st July). Precipitation, which is likely to affect the areas of lakes, did not vary between these two years. The average DOY of our 2009 dataset was 215 ±20 (3rd August) and was therefore comparable to the 2001-2002 baseline. Visual accuracy assessments were carried out on the water classifications (especially along overgrown lake margins), taking into account the extent of misclassifications due to shadows from clouds or mountains. We therefore did not apply any radiometric normalization during the mosaic-making process, in order to retain the original digital number (DN) values. Several classification iterations and subsequent visual inspections showed that Landsat's short wave infrared band 5, which has the same wavelength (1.55 - 1.75 µm) in both the TM and the ETM+ missions, provides the best results for surface water mapping. Characteristic for Landsat band 5 is the very high water absorption making it suitable for water detection. We therefore reclassified a narrow empirical DN value domain of high absorption (from 1 to 20, out of possible 256 DN, where higher values indicate higher reflectance) within this band as mapped water bodies. However, due to the absence of any independent control dataset for water bodies, we were unable to calculate accuracy statistics. A filter algorithm with a 3-by-3 opening was used to smooth the contours and remove small holes and fringes in the grid mask, especially along lake margins and in areas of shallow water. This operation significantly reduced the number of small water bodies but without having any major impact on the calculated total area covered by lakes. The filtered raster data was vectorized in order to calculate the total area covered by lakes and any changes in this area over time, and also to investigate relationships between changes in lake area and changes in lake topology. Floodplain lakes located close to river meanders showed highly dynamic surface areas that changed because of river water level fluctuations, and these were therefore removed manually. Only lakes with a size greater than or equal to 4 Landsat pixels were considered for further analysis.

title: Geocryological map of Yakutia, Russia - subsets of Yershov et al. 1991

description: Sheets 7 and 11 were scanned from the Russian version of "Geocryological map of Russia and neighboring republics, 1:2,500,000 scale" (Yershov et al. 1991). The English Language Edition of the Geocryological Map of Russia and Neighboring Republics - translations and commentary" (Williams and Warren, 2003) were used to translate the map legends. A subset of the map was manually vectorized in ArcGIS (digitized extent: WGS84, upper left corner: lat 65, long 117.55, lower right corner: lat 61.05, long 131.05). Selected layers were: Permafrost thickness (in meter), Volumetric Ice content (volume fraction), Distribution of cryogenic phenomena (ice wedges, frost heave mounds, thermokarst lakes and depressions, massive ice beds), Permafrost extent/coverage d=discontinuous, c=continuous, pc= Predominantly continuous permafrost, Surface geology (quaternary deposit), mean annual temperature (in °C at the depth of zero annual amplitude).ESRI shapefiles were stored as GCS WGS84 with an associated layer file for each theme.

title: Relative abundances of sea ice-related abundances in sediment core NBP01-01-JPC24

description: Micropaleontological and biomarker data from two high-accumulation marine sites from the Coastal and Continental Shelf Zone (CCSZ) off East Antarctica (Adélie Land at w140°E and eastern Prydz Bay at w77°E) are used to reconstruct Holocene changes in sea ice and wind stress at the basin-wide scale. These data demonstrate congruent increase in sea-ice concentration/persistence and wind stress-related sea-surface turbulence in the two regions since 7 cal ka BP, with a particularly strong signal since 4.5 - 3.5 cal ka BP. Comparison of these high latitude records with sea ice and turbulence records from the southern mid-latitudes highlights distinctive climatic evolutions according to the different latitudinal bands. Sea-ice persistence and turbulence increase in East Antarctica CCSZ are opposite to sea-surface warming and sea-ice retreat recorded after 4.5 - 3.5 cal ka BP in the East Atlantic and Indian sector between 55 and 45°S. At the same period, paleodata suggest SST cooling in all major coastal upwelling systems of the southern hemisphere, caused by the northward transport of subpolar surface waters as a response to southern Westerlies reinforcement. We therefore propose, as suggested for the northern hemisphere, that Holocene changes in the latitudinal insolation gradient, primarily forced by obliquity and precession and amplified by sea-ice and glacial-ice expansions in the Antarctic realm, are responsible for the observed contrasted latitudinal patterns of southern latitudes.

title: Trends of MODIS land surface temperature trend from 2000 to 2011, Yakutia, Siberia

description: For the land surface temperature trend analyses we used the MOD11C3 MODIS LST product configured on a 0.05° latitude/longitude MODIS Climate Model Grid (CMG) raster, which is a monthly composited average representing clear-sky LST values in °C. The monthly LSTs were analyzed over the 11 year interval from May 2000 to April 2011. Linear trend calculations for the 11 year interval were performed separately for each bi-monthly mean value in each grid cell, using the least squares method. We decided to use two-monthly intervals since the timing of thawing and freezing vary from year to year and do not necessarily occur over just one month in the year, or in the same month each year. We used a student t-test to calculate the significance of each trend, based on the assumption that there was no relationship between the date and the trend (null hypothesis). Similarly, we also calculated the trend of the mean annual LSTs.Data is provided as ascii-files with geographic coordinates added (WGS84).LST_year.zip contains three maps (ascii-files) 'LST_Grad_Year_Day', 'LST_Grad_Year_Night', 'LST_Grad_Year_Mean' with the calculated yearly trends for the period from 2001 to 2011 for just the day, just the night and the mean (of day and night) values. Corresponding 'LST_t_p_Day', 'LST_t_p_Night', 'LST_t_p_Mean' contain the statistical p-values from the t-tests.LST_bimonthly_trend.zip contains six maps 'grad_mar_apr', 'grad_may_jun', 'grad_jul_aug', 'grad_sep_oct', 'grad_nov_dec', 'grad_jan_feb' who show the calculated LST trends of the corresponding two month intervals over the 11 year time interval. The corresponding six maps 't_p_mar_apr', 't_p_may_jun', 't_p_jul_aug', 't_p_sep_oct', 't_p_nov_dec', 't_p_jan_feb' contain the p-values from the statistical t-test that belong to the bimonthly LST trends. LST_TtestIsolines.zip contains the isolines (as ESRI shapefile) from the t-test of the bimonthly trends of April/May and September/October for 75%, 90%, 95% and 97.5% confidence intervals.

title: Localization of ion-regulatory epithelia in embryos and hatchlings of two cephalopods

description: The tissue distribution and ontogeny of Na+/K+-ATPase has been examined as an indicator for ion-regulatory epithelia in whole animal sections of embryos and hatchlings of two cephalopod species: the squid Loligo vulgaris and the cuttlefish Sepia officinalis. This is the first report of the immunohistochemical localization of cephalopod Na+/K+-ATPase with the polyclonal antibody alpha (H-300) raised against the human alpha1-subunit of Na+/K+-ATPase. Na+/K+-ATPase immunoreactivity was observed in several tissues (gills, pancreatic appendages, nerves), exclusively located in baso-lateral membranes lining blood sinuses. Furthermore, large single cells in the gill of adult L. vulgaris specimens closely resembled Na+/K+-ATPase-rich cells described in fish. Immunohistochemical observations indicated that the amount and distribution of Na+/K+-ATPase in late cuttlefish embryos was similar to that found in juvenile and adult stages. The ion-regulatory epithelia (e.g., gills, excretory organs) of the squid embryos and paralarvae exhibited less differentiation than adults. Na+/K+-ATPase activities for whole animals were higher in hatchlings of S. officinalis (157.0 ± 32.4 µmol/g FM/h) than in those of L. vulgaris (31.8 ± 3.3 µmol/g FM/h). S. officinalis gills and pancreatic appendages achieved activities of 94.8 ± 18.5 and 421.8 ± 102.3 µmol ATP/g FM/h, respectively. High concentrations of Na+/K+-ATPase in late cephalopod embryos might be important in coping with the challenging abiotic conditions (low pH, high pCO2) that these organisms encounter inside their eggs. Our results also suggest a higher sensitivity of squid vs. cuttlefish embryos to environmental acid-base disturbances.

title: Data from: Decline of rare and specialist species across multiple taxonomic groups after grassland intensification and abandonment

description: Traditionally managed mountain grasslands are declining as a result of abandonment or intensification of management. Based on a common chronosequence approach we investigated species compositions of 16 taxonomic groups on traditionally managed dry pastures, fertilized and irrigated hay meadows, and abandoned grasslands (larch forests). We included faunal above- and below-ground biodiversity as well as species traits (mainly rarity and habitat specificity) in our analyses. The larch forests showed the highest species number (345 species), with slightly less species in pastures (290 species) and much less in hay meadows (163 species). The proportion of rare species was highest in the pastures and lowest in hay meadows. Similar patterns were found for specialist species, i.e. species with a high habitat specificity. After abandonment, larch forests harbor a higher number of pasture species than hay meadows. These overall trends were mainly supported by spiders and vascular plants. Lichens, bryophytes and carabid beetles showed partly contrasting trends. These findings stress the importance to include a wide range of taxonomic groups in conservation studies. All in all, both abandonment and intensification had similar negative impacts on biodiversity in our study, underlining the high conservation value of Inner- Alpine dry pastures.

title: Maintenance of coelomic fluid pH in sea urchins exposed to elevated CO2: the role of body cavity epithelia and stereom dissolution

description: Experimental ocean acidification leads to a shift in resource allocation and to an increased [HCO3-] within the perivisceral coelomic fluid (PCF) in the Baltic green sea urchin Strongylocentrotus droebachiensis. We investigated putative mechanisms of this pH compensation reaction by evaluating epithelial barrier function and the magnitude of skeleton (stereom) dissolution. In addition, we measured ossicle growth and skeletal stability. Ussing chamber measurements revealed that the intestine formed a barrier for HCO3- and was selective for cation diffusion. In contrast, the peritoneal epithelium was leaky and only formed a barrier for macromolecules. The ossicles of 6 week high CO2-acclimatised sea urchins revealed minor carbonate dissolution, reduced growth but unchanged stability. On the other hand, spines dissolved more severely and were more fragile following acclimatisation to high CO2. Our results indicate that epithelia lining the PCF space contribute to its acid–base regulation. The intestine prevents HCO3- diffusion and thus buffer leakage. In contrast, the leaky peritoneal epithelium allows buffer generation via carbonate dissolution from the surrounding skeletal ossicles. Long-term extracellular acid–base balance must be mediated by active processes, as sea urchins can maintain relatively high extracellular [HCO3-]. The intestinal epithelia are good candidate tissues for this active net import of HCO3- into the PCF. Spines appear to be more vulnerable to ocean acidification which might significantly impact resistance to predation pressure and thus influence fitness of this keystone species.
