| 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 |
| a survey of a mixed species aviary provides new insights into the pathogenicity, diversity, evolution, host range, and distribution of psittacine and passerine adenoviruses. | a bourke's parrot (neopsephotus bourkii) originating from an aviary in australia, containing two species of parrots, five species of finch and a species of dove, was presented for necropsy. the bourke's parrot died from gastritis caused by macrorhabdus ornithogaster, but also had an interstitial nephritis and ureteritis with adenovirus-like inclusion bodies within collecting duct epithelial cells. the adenovirus causing the lesions was shown to be psittacine adenovirus-2 (psadv-2) using a pcr as ... | 2019 | 31081348 |
| the impact of humidity on evaporative cooling in small desert birds exposed to high air temperatures. | environmental temperatures that exceed body temperature (tb) force endothermic animals to rely solely on evaporative cooling to dissipate heat. however, evaporative heat dissipation can be drastically reduced by environmental humidity, imposing a thermoregulatory challenge. the goal of this study was to investigate the effects of humidity on the thermoregulation of desert birds and to compare the sensitivity of cutaneous and respiratory evaporation to reduced vapor density gradients. rates of ev ... | 2014 | 25461643 |
| avian thermoregulation in the heat: efficient evaporative cooling allows for extreme heat tolerance in four southern hemisphere columbids. | birds show phylogenetic variation in the relative importance of respiratory versus cutaneous evaporation, but the consequences for heat tolerance and evaporative cooling capacity remain unclear. we measured evaporative water loss (ewl), resting metabolic rate (rmr) and body temperature (tb) in four arid-zone columbids from southern africa [namaqua dove (oena capensis, ∼37 g), laughing dove (spilopelia senegalensis, ∼89 g) and cape turtle dove (streptopelia capicola, ∼148 g)] and australia [crest ... | 2016 | 27207640 |
