Change of Leaf Morphology along Altitudinal Gradients
Advanced Materials Research, 2013It is the most effective way to study the effect of global warming on plant morphology by analyzing a plant species on a mount along altitudinal gradients. Altitudinal increase means decrease of temperature and metabolic rate as well. This might affect the leaf morphology greatly. The SEM study reveals that the size of nanopore on the epidermis changes

Leaf breakdown along an altitudinal stream gradient
Fundamental and Applied Limnology, 1998Breakdown 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 ...

Species Richness and the Analytic Geometry of Latitudinal and Altitudinal Gradients
Acta Biotheoretica, 2008Extensive empirical work has shown that species richness decreases roughly exponentially or quadratically with latitude. What appears to be a latitudinal gradient in fact may simply be a negative correlation of latitude with area at that latitude, due to convergence of lines of meridian at the poles.

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 ...

[Heat transfer, convection and altitudinal gradient].
Archivos de biologia y medicina experimentales, 1996Measurements of heat loss from fur covered aluminium cylinders were made under barometric pressures ranging from 760 to 368 torr (sea level up to 5.8 km, simulated altitudes). Heat transfer diminished at high altitudes and a relative greater diminution was observed when forced convection was applied.

Altitudinal gradients fail to predict fungal symbiont responses to warming
Ecology, 2019AbstractClimate change is shifting altitudinal species ranges, with potential to disrupt species interactions. Altitudinal gradient studies and warming experiments can both increase understanding of climate effects on species interactions, but few studies have used both together to improve predictions.

Stomatal Frequency Change Over Altitudinal Gradients: Prospects for Paleoaltimetry
Reviews in Mineralogy and Geochemistry, 2007Recently, a novel paleoaltimetry method was presented using leaf stomatal frequency response to the decline in CO 2 partial pressure with altitude, and tested on California black oak ( Quercus kelloggii ) (McElwain 2004). Here, we present new data detailing the influence of other climatic variables on leaf stomatal frequency change with altitude in ...

Diversity of Tricholomataceae along a mediterranean altitudinal gradient
Cryptogamie Mycologie, 2001Abstract This work studies variability in the composition of Tricholomataceae in different types of forest along an altitudinal gradient in the province of Madrid. It gives 26 new regional references, including most importantly Collybia aquosa, Clitocybe collina, Melanoleuca metrodiana, Cantharellula umbonata, Clitocybe decembris, Clitocybe ...
