A HARP SEAL × HOODED SEAL HYBRID

Marine Mammal Science, 1997
AbstractIn this study we report the first documentation of mating between harp (Phoca groenlandica) and hooded seals (Cystophora cristata). The production of this hybrid was quite unusual, being the result of a cross between parents of different genera which are morphologically dissimilar and have quite different mating behavior and dramatically ...

Phagocytic Activity of Leukocytes in Harp Seals

Doklady Biological Sciences, 2020
Phagocytic and cytochemical parameters of peripheral blood leukocytes in adult and 1.5-month-old harp seal pups were studied. Phagocytic number, proportion of phagocytic leukocytes, and phagocytic activity, average number of absorbed latex particles per leukocyte, were determined.

Body composition of harp seals

Canadian Journal of Zoology, 1994
Using chemical analysis we measured the composition of 26 harp seals (Phoca groenlandica) representing both sexes, aged between 3 months and 30 years, and encompassing a wide range of body conditions. Predictive relationships between total body water and total body fat contents, total body protein content, and gross energy were calculated.

ANESTHESIA OF THE HARP SEAL

Journal of Wildlife Diseases, 1972
The harp seal (Pagophilus groenlandicus) was anesthetized with halothane following induction with halothane/nitrous oxide or thiopental sodium. Halothane concentrations of 0.75 - 1.5% were required for surgical anesthesia. The depth of anesthesia was best assessed by heart rate, muscle relaxation and the presence or absence of shivering.

Radiative surface temperatures of harp seals

Comparative Biochemistry and Physiology Part A: Physiology, 1978
Abstract 1. 1. Ambient air temperature rather than wind speed or heat flow exerted the greatest effect on radiative heat loss from harp seal pup fur. 2. 2. Fur conductance was higher when calculated using radiative temperature rather than air temperature as representative of ambient temperatures. 3. ]3.

Pagophilus groenlandicus (Harp seal)

1973
The karyotypes are gifts of Dr. U. Amason, Lund, Sweden, and are prepared from solid tissue culture by the orcein squash method. The male comes from the St. Lawrence estuary, New found land, Canada, the female, from Kulusuk, Greenland. The X chromosomes of the female were identified by radioautography.

Mineral constituents of harp seal milk

Canadian Journal of Zoology, 1984
Milk samples were collected from stomachs of 20 harp seal pups (Phoca groenlandica) in the Gulf of St. Lawrence. Milk was analysed for ash content, 14 minerals, and for changes in mineral composition associated with maternal age and stage of lactation.

Methylmercury poisoning in the harp seal (Pagophilus groenlandicus)

Science of The Total Environment, 1977
Hematological and blood chemistry values were examined in harp seals (Pagophilus groenlandicus) exposed to daily oral dosages of methylmercuric chloride (MMC). Two seals, exposed to 0.25 mg MMC/kg body weight/day for 60 and 90 days, respectively, did not show abnormal blood values.
