| complete development of three species of haemoproteus (haemosporida, haemoproteidae) in the biting midge culicoides impunctatus (diptera, ceratopogonidae). | development of haemoproteus balmorali, h. dolniki, and h. tartakovskyi was followed in experimentally infected biting midges culicoides impunctatus on the curonian spit in the baltic sea. wild-caught flies were allowed to take blood meals on naturally infected spotted flycatchers muscicapa striata, chaffinches fringilla coelebs, or crossbills loxia curvirostra harboring mature gametocytes of these parasites. the engorged biting midges were collected, held at 14-18 c, and dissected daily. mature ... | 2002 | 12435121 |
| patterns of bird migration phenology in south africa suggest northern hemisphere climate as the most consistent driver of change. | current knowledge of phenological shifts in palearctic bird migration is largely based on data collected on migrants at their breeding grounds; little is known about the phenology of these birds at their nonbreeding grounds, and even less about that of intra-african migrants. because climate change patterns are not uniform across the globe, we can expect regional disparities in bird phenological responses. it is also likely that they vary across species, as species show differences in the streng ... | 2015 | 25640890 |
| bird diversity and distribution in relation to urban landscape types in northern rwanda. | using the point count method, linear mixed models, shannon's diversity index, and bray-curtis cluster analysis, we conducted a study of the effect of urban fabric layout on bird diversity and distribution in northern rwanda. the results showed a significant effect of city landscapes on bird richness and relative abundance; residential neighborhoods, institutional grounds, and informal settlements had the highest species diversity in comparison to other microlandscape types. riversides were chara ... | 2014 | 25133203 |
| the isolation and identification of bacteria on feathers of migratory bird species. | worldwide, bacteria are the most ubiquitous microorganisms, and it has been extensively demonstrated that migratory wild birds can increase bacterial global scale dispersion through long-distance migration and dispersal. the microbial community hosted by wild birds can be highly diverse, including pathogenic strains that can contribute to infections and disease spread. this study focused on feather and plumage bacteria within bird microbial communities. samples were collected during ornithologic ... | 2018 | 30563109 |
| the widespread biting midge culicoides impunctatus (ceratopogonidae) is susceptible to infection with numerous haemoproteus (haemoproteidae) species. | haemoproteus parasites are widespread, and some species cause disease in wild and domestic birds. however, the insect vectors remain unknown for the majority of species and genetic lineages of avian haemoproteus. this information is crucial for better understanding the biology of haemoproteids, the epidemiology of haemoproteosis, and the development of morphological characters of sporogonic stages in wildlife haemosporidian parasites. it remains unclear whether the specificity of haemoproteus pa ... | 2017 | 28841905 |
