background phlebotomus papatasi and p. salehi are reported as vectors of cutaneous leishmaniasis in southeast of iran. seasonal activity of these species is different in zoogeographical zones and must be known well for better management of the disease. objectives to determine the nocturnal activity of sand flies and their leptomonad infection rates. materials and methods a cross-sectional study...

Rates of oxygen consumption during hover-feeding of wild, unrestrained, adult male Anna hummingbirds (Calypte anna) were measured with an artificial outdoor feeder converted into a respirometer mask. A computer sampled changes in O2 concentration in air drawn through the mask, automatically detecting the presence of a hummingbird from a drop in the O2 concentration, and photoelectrically timing...
