Haemosporidian parasites of barred owls (Strix varia) and northern spotted owls (S. occidentalis caurina): investigating the effects of an invasive species on parasite transmission and community dynamics
Although the barred owl (Strix varia) was historically limited to eastern sections of North America, its range has steadily expanded westward over the past century. Currently the barred owl's range entirely overlaps the range of the federally threatened northern spotted owl (Strix occidentalis caurina) in the Pacific Northwest. Invasive species have been known to drastically impact a region's native species by altering the parasite communities among those species, yet little is known about the parasites of barred and northern spotted owls in particular. The purpose of this study was to determine ...
