Allonursing in captive belugas (Delphinapterus leucas)

Zoo Biology, 2010
This study describes allonursing (females nursing offspring that are not their own) in captive belugas (Delphinapterus leucas). In addition to the calf's mother, two females that were not pregnant or nursing at the time of the calf's birth spontaneously lactated and nursed the male calf intermittently throughout 34 months of his life at the Vancouver ...

Characterizing respiratory capacity in belugas (Delphinapterus leucas)

Respiratory Physiology & Neurobiology, 2019
We measured respiratory flow, breath duration, and calculated tidal volume (VT) in nine belugas (Delphinapterus leucas, mean measured body mass: 628 ± 151 kg, n = 5) housed in managed care facilities. Both spontaneous (resting at station) and trained maximal respirations (chuffs) were measured.

Microsatellites from the beluga whaleDelphinapterus leucas

Molecular Ecology, 1996
AbstractFifteen microsatellites were isolated from a beluga whaleDelphinapterus leucas, genomic library. The microsatellites were amplified in 100 beluga obtained from two widely separated locations. An average of 8.6 alleles per locus were detected and the average heterozygosity was 0.65 with a range of 0.27–0.86.

HEMATOLOGY AND SERUM CHEMISTRY VALUES IN THE BELUGA (DELPHINAPTERUS LEUCAS)

Journal of Wildlife Diseases, 1988
Normal values and ranges for 31 clinical hematology and serum chemistry tests are reported for the beluga or white whale (Delphinapterus leucas). The values were collected over a 6-yr period from eight belugas maintained for display at Sea World (San Diego, California, USA) facilities and represent long-term evaluations for each animal in a controlled ...

Anatomy of the heart of the beluga whale (Delphinapterus leucas)

Journal of Morphology, 1987
AbstractThe heart of the beluga whale (Delphinapterus leucas) is described from the dissection of seven specimens. As in most whales the heart is characterized by a transverse broadness and a flatness of the ventricles from one surface to the other and by an apex formed by both ventricles.

Delphinapterus leuca (Beluga whale)

1977
The karyotypes were donated by Dr. Deborah A. Duffield and come from lymphocyte cultures. The female karyotype is C-banded. The last pair of autosomes has distinct satellite with heteromorphic C-band.

Investigation of lateralization of socio-sexual behavior in belugas (Delphinapterus leucas)

Behavioural Processes, 2022
The majority of cetacean research suggests a right side/left cerebral hemisphere bias for processing visuospatial information and a left side/right cerebral hemisphere bias for processing social information. Beluga (Delphinapterus leucas) socio-sexual behavior involves motor skills coordination and is also hypothesized to serve a social function.

Mandibular Layering in Delphinapterus leucas and Age Determination

Nature, 1969
LAWS1 investigated mandibular periosteal layers as an aid to ageing the Sperm whale Physeter catodon. Continued studies of P. catodon indicate that mandibular layers and tooth layers occur in equal numbers2, and it has been postulated that two tooth layers are deposited annually3. Two tooth and one mandibular layer in Delphinus delphis are annual4.

SUCCESSFUL TREATMENT OF A SEVERE CASE OF FUSARIOMYCOSIS IN A BELUGA WHALE (DELPHINAPTERUS LEUCAS LEUCAS)

Journal of Zoo and Wildlife Medicine, 2012
An adult male beluga whale (Delphinapterus leucas leucas) was presented with a 4-cm-diameter, raised, firm nodule on the medial aspect of the left pectoral fin. A fissure developed within the center of the nodule, which formed an ulcerated cyst-like lesion.

Nucleotide sequence of the p53 cDNA of beluga whale (Delphinapterus leucas)

Gene, 2002
The cDNA (DNA complementary to RNA) of the p53 gene of the beluga whale (Delphinapterus leucas) was sequenced by the method of 5'- and 3'-rapid amplification of cDNA ends (RACE) with the cDNA made for the RNA obtained from fresh peripheral blood leukocytes isolated from two animals.
