| cloacal evaporation: an important and previously undescribed mechanism for avian thermoregulation. | we present the first experimental evidence that a bird is capable of evaporating enough water from the cloaca to be important for thermoregulation. we measured rates of evaporation occurring from the mouth, the skin, and the cloaca of inca doves columbina inca lesson and eurasian quail coturnix coturnix linnaeus. inca doves showed no significant increase in cutaneous evaporation in response to curtailment of buccopharyngeal evaporation. cloacal evaporation in doves was negligible at ambient temp ... | 2007 | 17297135 |
| helminth community composition, structure, and pattern in six dove species (columbiformes: columbidae) of south texas. | abstract abstract: the helminth community composition and structure of 6 species of columbids residing in south texas are reported and compared herein. sixty rock pigeons, columba livia (rp), mourning doves, zenaida macroura (md), eurasian collared-doves, streptopelia decaocto (ecd), white-winged doves, zenaida asiatica (wwd), common ground doves, columbina passerina (cgd), and 48 inca doves, columbina inca (id), were collected during the summer of 2006 and examined for helminths. twelve he ... | 2011 | 21955248 |
| direct calorimetry reveals large errors in respirometric estimates of energy expenditure. | knowledge of animal energetics is based largely upon indirect calorimetry, which is estimation of metabolic heat production by an organism from measurement of indices such as oxygen consumption or carbon dioxide production. remarkably, indirect calorimetry has been validated by comparison to direct measurements of metabolic heat production (direct calorimetry) only for highly restricted conditions, primarily with a few species of medium-to-large mammals. taxa with differing physiologies are litt ... | 2005 | 15767305 |
| experimental transmission of chlamydia psittaci to turkeys from wild birds. | wild birds were inoculated with chlamydia psittaci to determine species that could be potential hosts and vectors in transmitting the agent to domestic turkeys. infection occurred in turkeys exposed to starlings (sturnus vulgaris), common grackles (quiscalus quiscula), brown-headed cowbirds (molothrus ater), and inca doves (cardafella inca). mourning doves (zenaidura macroura) shed the agent sparingly, but turkeys exposed to them did not become infected, these findings and knowledge of the habit ... | 1979 | 546413 |
| the stereoscanning electron microscopy and ultrastructural histochemistry of the avian and reptilian surfactant systems: indian dove, desert spiny and taiwan golden skink lizards. | lung tissues from the indian dove, scardafella inca, desert spiny lizard, sceloporus magister, and the taiwan golden skink lizard, mabuya aurates, were studied by transmission electron microscopy utilizing ruthenium red as a carbohydrate stain and with the so-called lipid-carbohydrate retention procedures to elucidate the morphology of the surfactant systems. stereoscopic scanning electron microscopic procedures were utilized for a comparative anatomical study of these three species, and the res ... | 1980 | 6893527 |

| coi barcodes and phylogeny of doves (columbidae family). | cytochrome oxidase subunit i (coi) gene has been recognized as an authentic tool for species identification. besides its potential barcoding capacity, coi sequences have also been used for inferring the phylogeny. phylogenetic relationships among genera of columbidae (pigeons and doves family) have not been fully resolved because of scarce sampling of taxa and limited availability of sequence data. in this study, we have evaluated the efficiency of coi barcodes for species identification and phy ... | 2013 | 23544616 |
| seasonal changes of the adrenocortical response to stress in birds of the sonoran desert. | many avian species of the north american sonoran desert, e.g., the black-throated sparrow, amphispiza bilineata, cactus wren, campylorhynchus brunneicapillus, and curve-billed thrasher, toxostoma curvirostre, can potentially breed from march/april to august. it is possible that, at least in summer, intense heat and aridity may have inhibitory effects on breeding by precipitating a stress response. stress typically results in a rise in secretion of adrenocorticosteroid hormones that then inhibit ... | 1992 | 1460439 |
