| cross-scale effects of spruce budworm outbreaks on boreal warblers in eastern canada. | insect outbreaks are major natural disturbance events that affect communities of forest birds, either directly by affecting the food supply or indirectly by changing the vegetation composition of forest canopies. an examination of correlations between measures of bird and insect abundance across different spatial scales and over varying time lag effects may provide insight into underlying mechanisms. we developed a hierarchical bayesian model to assess correlations between counts of eight warble ... | 2018 | 30151153 |
| the malaria parasite plasmodium relictum in the endemic avifauna of eastern cuba. | island populations are vulnerable to introduced pathogens, as evidenced by extinction or population decline of several endemic hawaiian birds caused by the malaria parasite, plasmodium relictum (order haemosporida). we analyzed blood samples from 363 birds caught near guantánamo bay, cuba, for the presence of haemosporidian infections. we characterized parasite lineages by determining nucleotide variation of the parasite's mitochondrial cyt b gene. fifty-nine individuals were infected, and we id ... | 2017 | 28766818 |
| 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 |
