Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Understanding fine‐scale surface changes is crucial for quantifying ecosystem dynamics and detecting landscape changes. Palsas, comparably small peatland elevations with an ice‐rich permafrost core, undergo natural cycles of growth and degradation. They can also serve as indicators of climate change in subarctic regions. Because they typically

Altitudinal Gradient May Shadow the Effects of Altitudinal Range on Species Diversity
Applied Mechanics and Materials, 2014Altitudinal range is widely used as a proxy of habitat heterogeneity to explain broad-scale geographical patterns of species diversity. Though altitudinal range is a factors derived from altitudinal gradient, altitudinal range’s effects on species diversity on altitudinal gradient remain little known.

Leaf breakdown along an altitudinal stream gradient
Fundamental and Applied Limnology, 1998 Breakdown of alder (Alnus glutinosa) leaf litter was followed in fourteen sampling stations along a 1400 m altitudinal gradient of a 1st to 3rd-order undisturbed stream. Altitudinal patterns of leaf mass loss, nitrogen concentration in the leaves, fungal biomass determined as ergosterol content, and numbers and biomass of shredders and total ...

Altitudinal Gradients of Soil Temperatures in Europe
Transactions of the Institute of British Geographers, 1980The altitudinal gradient of soil temperature is examined with the aid of observations from ten countries in Europe. It is shown that this altitudinal gradient is always greatest in summer and least in winter, and that only the amplitude of the seasonal variation differs from one region to another.

Leaf wettability decreases along an extreme altitudinal gradient
Oecologia, 2009The duration and amount of water captured on leaves and its functional significance is highly varied. Leaf surface wettability influences water absorption, gas exchange, pathogen infection, nutrient leaching, contamination by pollutants, self-cleaning properties and in freezing environments the probability of extrinsic ice nucleation.

Altitudinal Gradients in Mycorrhizal Symbioses
2017Mountains, due to their often steep gradients in abiotic and biotic factors, offer an ideal setting to improve our understanding of mechanisms that underlie species distribution and community assembly. The current knowledge on the effects of elevation on richness and community composition is almost entirely based on vascular plants and animals, where ...

The Altitudinal Gradients of Air Temperature in Southern Norway
Geografiska Annaler: Series A, Physical Geography, 1980ABSTRACT. Following from an earlier paper on the altitudinal gradients of temperature in the British Isles (Harding, 1978) a statistical study is made of the more extensive network of upland observations from southern Norway. The effects of altitude are found to be similar in the two regions: the mean values of the altitudinal gradients are the same ...
