(For more information see climate: Climatic classification: World distribution of major climatic types: Highland climates.) Altitude affects climate because atmospheric temperature drops with increasing altitude by about 0.5 to 0.6 °C (0.9 to 1.1 °F) per 100 metres (328 feet).
The highland-tropical climatic area of the Adamaoua highlands (AH) is characterized by mean annual rainfall above 1,500 mm, and mean annual temperature around 22°C.
Three FGDs were formed: one focus group in each of the upper-highland, highland, and midlands ago-climatic zones.
In addition, a recent study done by the same authors in 2012 based on serology estimated by using a Bayesian model and herd level sero-prevalence was higher in the midland (64 %) as compared to the lowland (50 %) and the highland (26 %) agro-climatic Zones of Ethiopia.
This is independently corroborated 1) by the synchronous occurrence of pollen clumps indicating disturbance effects from trampling and 2) the precipitous decline of forest pollen on the eastern declivity of the highland during the mid-Holocene climatic optimum.
This supports the conclusion of Watson et al. and Snell et al. [33], [34], that the humid highlands are the most degraded climatic zone in Galapagos, due to invasion by alien species, whereas the largely undisturbed, more arid lowlands are not yet experiencing widespread plant invasion.
In addition, there was no significant association between seropositivity to LSD and, the agro-climatic zones (midland and highland).
If not extinct, the microorganism that caused cocoliztli may remain hidden in the highlands of Mexico and under favorable climatic conditions could reappear.
Administratively, the district has seven divisions with 161 registered villages and is divided into four geographic-climatic areas: wet-highland, dry-highland, wet-lowland and dry-lowland [District annual report, 2002].
Stratified random sampling was performed by dividing rural villages into the four geographic-climatic areas, wet-highland, dry-highland, wet-lowland and dry-lowland, using a list of villages from the national census.
