Altitudinal Gradient May Shadow the Effects of Altitudinal Range on Species Diversity

Applied Mechanics and Materials, 2014
Altitudinal 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.

Altitudinal Gradients of Soil Temperatures in Europe

Transactions of the Institute of British Geographers, 1980
The 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, 2009
The 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.

The Altitudinal Gradients of Air Temperature in Southern Norway

Geografiska Annaler: Series A, Physical Geography, 1980
ABSTRACT. 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 ...
