Attacks on the endangered Attwater's Prairie-Chicken (Tympanuchus cupido attwateri) by black flies (Diptera: Simuliidae) infected with an avian blood parasite.

چکیده
With fewer than 50 birds remaining in the wild, Attwater's Prairie-Chicken (Tympanuchus cupido attwateri) is critically endangered. Individuals of this species on the Attwater Prairie Chicken National Wildlife Refuge, Colorado Co., TX, have been attacked in successive winters, 2005-2006, by the blood-feeding black fly Cnephia ornithophilia. Attwater's Prairie-Chicken is a previously unreported host for Cnephia ornithophilia. Molecular screening indicated that about 15% of 13 blood-fed flies sampled from captured Attwater's Prairie-Chickens carried a parasite of the genus Leucocytozoon that can cause a debilitating avian malaria-like disease. If blood feeding or transmission of the disease agent becomes a threat to the birds, particularly in years of lean food supply or harsh weather, management of Cnephia ornithophilia should be considered.

The Attwater's prairie chicken (APC; Tympanuchus cupido attwateri Bendire, 1894) has been a federally listed endangered species since 1967. Several captive propagation programs consisting of small populations are being used to keep this species from extinction. Fecal samples were collected from APCs in April 2007 and again in August 2008 from 2 separate captive propagation facilities in Texas a...

Prairie grouse (genus: Tympanuchus) once existed throughout much of North America but have recently experienced significant population declines, isolation, and extinction. In previous molecular studies, contrasting patterns or an unresolved polytomy among Tympanuchus taxa (Tympanuchus phasianellus, Tympanuchus pallidicinctus, and Tympanuchus cupido) have resulted from traditional phylogenetic m...

The invasive red imported fire ant (Solenopsis invicta) has negatively affected a host of taxonomic groups throughout its acquired North American range. Many studies have hypothesized indirect trophic impacts, but few documented those impacts. We evaluated invertebrate abundance as a factor limiting juvenile survival of the endangered Attwater's prairie-chicken (Tympanuchus cupido attwateri), a...

Recurring infection of reticuloendotheliosis virus (REV), an avian oncogenic gammaretrovirus, has been a major obstacle in attempts to breed and release the endangered Attwater's prairie chicken (Tympanicus cupido attwateri). The aim of this study was to develop a DNA vaccine that protects the birds against REV infection. A plasmid was constructed expressing fusion proteins of REV envelope (env...

Reoccurring infection of reticuloendotheliosis virus (REV), an avian oncogenic retrovirus, has been a major obstacle in attempts to breed and release an endangered grouse, the Attwater's prairie chicken (Tympanicus cupido attwateri). REV infection of these birds in breeding facilities was found to result in significant decreases in the CD4(+) and increases in the CD8(+) lymphocyte populations, ...
