| varying land-use has an influence on wattled and grey crowned cranes' abundance and distribution in driefontein grasslands important bird area, zimbabwe. | three species of cranes are distributed widely throughout southern africa, but little is known about how they respond to the changes in land-use that have occurred in this region. this study assessed habitat preference of the two crane species across land-use categories of the self contained small scale commercial farms of 30 to 40 ha per household (a1), large scale commercial agriculture farms of > 50 ha per household (a2) and old resettlement, farms of < 5 ha per household with communal grazin ... | 2016 | 27875552 |
| scanning electron microscopic study on the tongues of seven avian species. | the dorsal lingual surface of the grey crowned crane (balearica regulorum), american flamingo (phoenicopterus rubber), great egret (ardea alba), mallard (anas platyrhynchos), himalayan monal (lophophorus impejanus), black-necked stilt (himantopus mexicanus) and green macaw (ara militaris) were examined by scanning electron microscopy. in the grey crowned crane, the surface of the lingual apex was relatively rough. many openings of the lingual glands in both lateral regions of the lingual body we ... | 2016 | 27904021 |
| the african crane database (1978-2014): records of three threatened crane species (family: gruidae) from southern and eastern africa. | the international crane foundation (icf) / endangered wildlife trust's (ewt) african crane conservation programme has recorded 26 403 crane sightings in its database from 1978 to 2014. this sightings collection is currently ongoing and records are continuously added to the database by the ewt field staff, icf/ewt partnership staff, various partner organizations and private individuals. the dataset has two peak collection periods: 1994-1996 and 2008-2012. the dataset collection spans five african ... | 2016 | 27956850 |
| microsatellite loci characterized in three african crane species (gruidae, aves). | forty-three microsatellite loci originally isolated in grus americana and g. japonensis were tested for polymorphism in the blue crane (g. paradisea). amplified products were sequenced in the blue crane to aid in the design of blue crane-specific primers. when characterized in 20 unrelated blue crane individuals from south africa, 14 loci were polymorphic, with each locus displaying between 2 and 7 alleles. eight polymorphic loci were characterized in the grey-crowned crane (balearica regulorum) ... | 2009 | 21564635 |
| [sex determination in ten crane species by dna marker ee0.6]. | using a unique dna sequence of w-chromosome ee0.6, we carried out molecular sex determination in 383 individuals often species of cranes (grusgrus l., g. leucogeranus pallas, g. japonensis muller, g. vipio pallas, g. canadensis l., g. antigone l., g. monacha temminck, anthropoides virgo l., balearica regulorum bennett, and b. pavonia l.) kept in zoos and other centers of captive propagation. in 211 birds, sex was determined or verified for the first time. the efficiency of using the sex marker e ... | 2013 | 25508137 |

| respiratory responses to acute heat stress in cranes (gruidae): the effects of tracheal coiling. | some species of cranes have extensive coiling of their trachea that substantially increases their anatomical dead space. we subjected individuals of four species of cranes (anthropoides virgo, balearica regulorum, grus grus and grus japonensis) to acute heat stress to investigate the effectiveness of this trait as a thermoregulatory adaptation. we measured cloacal temperature, respiratory flow and frequency and arterial ph during normothermic breathing and thermal panting. extra tracheal length ... | 1985 | 4070839 |
| co-inections of domestic and wild birds with avian influenza and newcastle disease viruses: implications for control and genetic mutations. | co-infections of birds' upper respiratory tract by avian pathogens are common and cause increasing economic losses. this study determines co-infection status of avian influenza (ai) and newcastle disease (nd) in birds in two nigerian states with different highly pathogenic avian influenza (hpai) records and where modified stamping out policy contained the virus for seven years after which the virus resurged with higher infectivity in 2015. a cross-sectional study sampling 910 apparently healthy ... | 2020 | 33040313 |
| whole genome analysis of the red-crowned crane provides insight into avian longevity. | the red-crowned crane (grus japonensis) is an endangered, large-bodied crane native to east asia. it is a traditional symbol of longevity and its long lifespan has been confirmed both in captivity and in the wild. lifespan in birds is known to be positively correlated with body size and negatively correlated with metabolic rate, though the genetic mechanisms for the red-crowned crane's long lifespan have not previously been investigated. using whole genome sequencing and comparative evolutionary ... | 2020 | 31940721 |
