Studies of mosquito preferences for avian hosts have found that some bird species are at greater risk than others of being fed upon by mosquitoes. The ecological factors that determine this interspecific variation in avian host use by mosquitoes have been little studied, despite the possibility that such variation may...
For a variety of infectious diseases, the richness of the community of potential host species has emerged as an important factor in pathogen transmission, whereby a higher richness of host species is associated with a lowered disease risk. The proposed mechanism driving this pattern is an increased likelihood in species-rich...
Objectives of this investigation were two-fold: (l) to determine
crested wheatgrass production on selected range sites and (2)
to evaluate present and potential production on public and private
lands in the study area. Field studies were carried out in 1953 and
1964 near Jordan Valley, Malheur County, Oregon, on the...
