A total of 750 rodents and shrews were trapped in several sites on Mount (Mt.) Kilimanjaro and in two lowland sites between October 2002 and August 2003. Species diversity variations with altitude and their distribution were established. Diversity of species varied with vegetation type, being highest in the forest and lowest in the lowland areas. The distribution patterns and species diversity ...

The biting activity of Culex ribeirensis was studied in the highland region of Southern Brazil and compared with data previously obtained in a lowland area of the same region. Hourly sampling with human bait showed a bimodal pattern, with a greater peak in the evening crepuscular period. Behavior was similar in both the highland area of Lupo Farm and the lowland of the Ribeira Valley but with a...

1. The duration of maximal activity and the intensity of anaerobic metabolismwere measured in lowland Sceloporus occidentalis at low (200 ft) and high (10,150 ft) elevations and compared to those of resident S. occidentalis and S. graciosus at high altitude. 2. The duration of maximal activity is independent of altitude: all groups of S. occidentalis had the same stamina, regardless of the alti...
