| epizootic podoknemidokoptiasis in american robins. | epizootics of scaly leg disease caused by infection with the submacroscopic mite knemidokoptes jamaicensis (acari: knemidokoptidae) in migratory american robins (turdus migratorius) from a residential area of tulsa (oklahoma, usa) are documented during the winters (december through february) of 1993-94 and 1994-95. estimates of 60 to > 80% of the birds in several different flights arriving in the area had lesions consistent with knemidokoptic mange. epizootic occurrence of k. jamaicensis also is ... | 1999 | 10073340 |
| can selection by an ectoparasite drive a population of red crossbills from its adaptive peak? | the bill structures of different call types of red crossbills (loxia curvirostra complex) in western north america usually approximate the predicted optima for foraging on single species of conifers. one clear exception is the call type in the south hills, idaho, that is coevolving in an evolutionary arms race with rocky mountain lodgepole pine (pinus contorta ssp. latifolia). although south hills crossbills forage only on the cones of these lodgepole pines, their average bill depth is smaller t ... | 2005 | 16261739 |
| survival and population size of a resident bird species are declining as temperature increases. | 1. a large number of migratory bird species appear to be declining as the result of climate change, but whether resident bird species have or will be adversely affected by climate change is less clear. we focus on the south hills crossbill (loxia curvirostra complex), which is endemic to about 70 km(2) of rocky mountain lodgepole pine (pinus contorta latifolia) forest in southern idaho, usa. 2. our results indicate that the south hills crossbill has declined by over 60% between 2003 and 2008, a ... | 2011 | 22010811 |

| multidisciplinary analysis of knemidocoptes jamaicensis parasitising the common chaffinch, fringilla coelebs: proofs for a multispecies complex? | the number of studies discussing the pathology and host specificity in knemidocoptinae is very limited. in knemidocoptes jamaicensis, the host specificity seems to be very broad, and there is a clear morphological variability in individuals originating from various bird species; hence, serious doubts appear about the species status of this mite. we report a multidisciplinary approach to the taxonomy, morphology, ecology, and pathology of k. jamaicensis. the source of the mites in our study was a ... | 2013 | 23563901 |
| knemidokoptic mange in hawai'i' amakihi (hemignathus virens) on the island of hawai'i. | lesions resembling knemidokoptic mange on the feet and tarsometatarsi of two hawai'i' amakihi (hemignathus virens) were observed while the researchers were mist-netting wild passerines at manuka natural area reserve on the island of hawai'i between 14 june 2007 and 19 june 2007. during subsequent mist-netting from september 2007 through february 2008, we found 26% (7/27) of the hawai'i' amakihi caught were similarly affected. microscopic examination of skin scrapings from lesions of affected ind ... | 2009 | 19395759 |
| patterns of knemidokoptes jamaicensis (acari: knemidokoptidae) infestations among eight new avian hosts in the dominican republic. | the ectoparasitic mite knemidokoptes jamaicensis turk burrows into the cornified epithelium of the legs and feet of passeriform birds and has been reported from 12 species of north american birds. here we establish new host and distribution records for k. jamaicensis from eight species of birds from three habitats in the dominican republic. these species include hispaniolan pewee (contopus hispaniolensis bryant), northern mockingbird (mimus polyglottos l.), cape may warbler (dendoica tigrina gme ... | 2001 | 11372970 |
| ectoparasites of the black-chinned siskin spinus barbatus (passeriformes: fringillidae) in chile. | despite being a bird with a broad and extensive distribution in chile, the black-chinned siskin, spinus barbatus molina, 1782 is not well studied in relation to its parasites. this paper aims to describe the ectoparasite fauna of s. barbatus in central and southern chile. a total of 125 individuals caught with mist nets were examined alive; a total of 22 parasites were found dead and were exposed to parasit autopsy. the extracted parasites were preserved in 70% alcohol for subsequent mounting an ... | 2016 | 27982296 |
