Sentence examples for mean annual aridity from inspiring English sources

Therefore, we selected two layers which are likely to be important to C. decresii given that the species is a semi-arid, rocky habitat specialist: mean annual aridity index (the monthly ratio of precipitation to potential evaporation and an indicator of dryness) and topographic relief (the range in elevation).

By contrast, we detected strong relationships between colour morph frequencies and a broad environmental gradient (mean annual aridity index) and microhabitat feature (vegetation cover).

However, we detected remarkably strong associations between morph frequencies and two environmental variables (mean annual aridity index and vegetation cover), which together explained approximately 45%% of the total variance in morph frequencies.

Mean annual aridity index and topographic relief across the range of northern C. decresii with values for Aroona (A), Bimbowrie Station (BS), Devil's Peak (DP), Mt Remarkable (MR), Telowie Gorge (TG), Wilpena (W), Warren Gorge (WG) and Yourambulla Caves (YC).

Correlations among geographic distance (distance), mean annual aridity index (aridity), topographic relief (topography), proportion cover of vegetation <1 m in height (vegetation), and proportion cover of rocks >50 cm in diameter.

Results of four separate multiple regression analyses with the frequency of each colour morph (orange, orange-yellow, yellow and grey) as the dependent variables and mean annual aridity index (aridity) and proportion cover of vegetation <1 m in height (vegetation) as the predictor variables.

However, differences in flood processes among sites are better explained by a set of new catchment descriptors introduced into hydrological regression models, such as new characteristics derived from the slope of flow duration curves, the ratio of mean annual precipitation to extreme precipitations and the aridity index.

Among tomato species, we find that each has a unique combination of characteristic environmental variables (Nakazato et al. 2010; Fig. 1); moreover, the most prominent axis of species differentiation is habitat aridity (e.g. mean annual rainfall) (Nakazato et al. 2010).

We found that both the concentrations of all SON fractions and the proportion of more stable SON increased with increasing aridity index (AI, defined as mean annual precipitation/potential evapotranspiration).

Within each latitude, two locations were chosen so as to differ markedly in aridity index (AI; Willmott and Feddema 1992), the ratio of mean annual precipitation (MAP) to potential evapotranspiration (PET).

The aridity index is a fraction of annual precipitation in millimetres over mean annual temperature in degrees Centigrade plus ten (P/(T+10)) (De Martonne 1926; Thornthwaite 1931).
