Seasonally snow covered areas of the mountain ranges are important components in the global hydrologic cycle. Therefore monitoring the extent of the seasonal snow cover and the accumulation and ablation zones of glaciers is essential for understanding of the global hydrologic cycle, one of the objectives in the study of the Earth sciences. Seasonal snow cover is the major source of the fresh wa...

We studied the influence of two overwintering microenvironments on survival and potential fecundity of goldenrod gall flies, Eurosta solidaginis (Fitch) (Diptera, Tephritidae). These freeze-tolerant larvae overwinter above the snow on standing goldenrod stems (elevated) or below the snow on broken stems (ground-level). When covered by snow, the ground-level larvae were well insulated and thus p...

Mountain snowpack provides critical water resources for forest and meadow ecosystems that are experiencing rapid change due to global warming. An accurate characterization of heterogeneity in these requires snow cover observations at high spatial resolutions, yet most existing datasets have a coarse resolution. To advance our observation capabilities meadows forests, we developed machine learni...

During the winter of 2005/06, record-breaking snow accumulations were observed in many locations in south-east Germany, large parts of Austria and in the low mountain ranges along the Czech/German as well as Czech/Austrian borders. In the lowlands, low mountain ranges and eastern Alpine valleys of the above-mentioned study area, the snow mantle reached its maximum depth in early to mid-March, w...

In mountains with seasonal snow cover, the effects of climate change on snowpack will be constrained by landscape-vegetation interactions with the atmosphere. Airborne lidar surveys used to estimate snow depth, topography, and vegetation were coupled with reanalysis climate products to quantify these interactions and to highlight potential snowpack sensitivities to climate and vegetation change...
