Standard hematologic and serum chemistry parameters were determined from 28 harp seals (Phoca groenlandica) and 20 hooded seals (Cystophora cristata) sampled from 6 March 2001 to 13 March 2001 during the breeding season. Whole blood was collected immediately postmortem from harp seal mother–pup pairs and from six hooded seal pups, and from live-captured adult hooded seals and three hooded seal pups; blood was analyzed within 24 hr at a local human hospital. A certified veterinary laboratory… Expand
Size and distribution of oxygen stores in harp and hooded seals from birth to maturity
TLDR
Comparisons with other phocid species suggests that the pattern of blood and muscle development in the pre- and post-natal periods varies with terrestrial period, and that muscle maturation rates may influence the length of the postweaning fast. Expand
New data on the cellular composition of the hooded seal blood
TLDR
The morphological and morphometric analyses and the leukogram have demonstrated peculiarities of cell composition of hooded seal pups, and a large number of immature eosinophils were found in all animals studied. Expand
Comparative Health Assessments of Alaskan Ice Seals
TLDR
Initial baseline parameters for hematology, serum chemistries, and other species-level indicators of health that can be used to assess the condition of individual seals, inform monitoring and management efforts, and guide directed research efforts for Alaskan populations of ice-associated seals are provided. Expand
Concentrations of Selected Essential and Non-essential Elements in Blood of Harbor Seal (Phoca vitulina) Pups of the German North Sea
TLDR
Higher concentrations of Al, As, Fe, Mo, and Zn in blood samples of newborns compared to samples collected later, probably due to transplacental and lactational transfer from mother to fetus, are found. Expand
New data characterizing the metabolic status of hooded (Cystophora cristata Erxleben, 1777) and harp (Pagophilus groenlandica Erxleben, 1777) seals in the early postnatal period of development
TLDR
The study of metabolism of the hooded seal arouses an interest related to some peculiarities distin guishing this species among other Arctic pinnipeds, in particular, the shortest period of milk nourishment (about four days versus 12–14 days in other species). Expand
Analysis of blood gases, serum fat and serum protein: a new approach to estimate survival chances of stranded Harbor seal (Phoca vitulina) pups from the German North Sea
TLDR
For the first time blood gas values are reported in this study for a large sample size (N = 99) of seal pups (regardless of their health status) and can serve as a stepping stone towards the establishment of reference values for neonate harbor seals. Expand
Hematology and serum biochemistry of farmed bullfrog, Lithobates catesbeianus during the active and hibernating periods
TLDR
Differences between sexes showed that male bullfrogs possessed a statistically higher LDH activity level, and statistically lower levels of Cre, Na and Ca concentrations, and significantly higher values for WBCs counts and Cre than the hibernating ones. Expand
Health and condition in the adult Weddell seal of McMurdo Sound, Antarctica.
TLDR
Serum chemistry suggested that females were better nourished and displayed lower indicators of acute stress compared to males, and future physiological studies in this species are strongly encouraged to incorporate potential sex effects in experimental design and analysis. Expand
Seawater drinking restores water balance in dehydrated harp seals
TLDR
It is shown that harp seals have the capacity to gain net water from mariposa (voluntarily drinking seawater) and are able to restore water balance after profound dehydration by drinking seaw water. Expand
Effects of complex organohalogen contaminant mixtures on thyroid homeostasis in hooded seal (Cystophora cristata) mother-pup pairs.
TLDR
The results suggest that thyroid homeostasis is affected in hooded seals, and that the inclusion of the fullest possible OHC mixture is important when assessing TH related effects in wildlife. Expand

Reference values for serum biochemical parameters in free-ranging harp seals.
TLDR
Serum levels of glucose and triglycerides were lower, but serum levels of urea were higher in dead animals than in animals that were captured alive, and both sampling method and age should be considered when evaluating the results of future analysis of serum parameters in wild and captive harp seals. Expand
Hematology and chemistry reference values for free-ranging harbor seals (Phoca vitulina) and the effects of hemolysis on chemistry values of captive harbor seals.
TLDR
Hmatology and chemistry values in adults were similar to those reported for free-ranging and captive harbor seals, except for glucose, urea nitrogen, and lactate dehydrogenase (LDH) values, which were higher than those reported previously. Expand
HEMATOLOGY AND SERUM CHEMISTRY COMPARISONS BETWEEN FREE-RANGING AND REHABILITATED HARBOR SEAL (PHOCA VITULINA RICHARDSI) PUPS
TLDR
Compared the hematology and serum chemistry values between free-ranging and stranded harbor seal pups and to ascertain how blood values of stranded pups changed during the rehabilitation process, rehabilitated pups increased significantly after 2–3 mo in captivity. Expand

TLDR
In the pups and yearlings, total WBC, total protein, and glucose values increased until weaning and declined during the postweaning fast, and consideration should be given to the growth phase of gray seal pups or stage of development when hematology and clinical chemistries are used for diagnostic purposes.

HEALTH STATUS OF HARP SEALS (PHOCA GROENLANDICA) AND HOODED SEALS (CYSTOPHORA CRISTATA) ON SABLE ISLAND, NOVA SCOTIA, CANADA, CONCURRENT WITH THEIR EXPANDING RANGE
TLDR
Some harp and hooded seals expanding their range in recent years may be unable to feed successfully, although the reasons for this are unclear. Expand
Changes in blood properties of fasting and feeding harp seal pups, Phoca groenlandica, after weaning
TLDR
Calcium and phosphorus levels in fasting pups were lower than in feeding pups, and other monitored blood parameters exhibited no significant differences between feeding and fasting animals and were within the range of normal values previously reported for harp seals. Expand
Blood volume in hooded seals: implications for diving capacity
TLDR
Blood volume range was 104-162 mL/kg M, and the skeletal muscle mass of two adult females represented 30.8 and 28.1% of their M, based on which the body oxygen store of a 150-kg seal was estimated to be 9.8 L O2. Expand
Estimated Prey Consumption by Harp seals (Phoca groenlandica), Hooded seals (Cystophora cristata), Grey seals (Halichoerus grypus) and Harbour seals (Phoca vitulina) in Atlantic Canada
TLDR
Of the 3.1 million tons of fish consumed by the four species of seals in 1996, only about 20% accounted for commercial species such as Greenland halibut, Atlantic cod, redfish, and Atlantic herring; most of the consumption of these commercial species consisted of juveniles. Expand
Energetics of lactation in harp seals (Phoca groenlandica) from the gulf of St. Lawrence, Canada
TLDR
Feeding does not appear to be required in order to achieve the energy requirements for lactation, given the energy stores possessed by females, and some females do fast through the entire period so feeding may be considered opportunistic in nature. Expand
Functional Hematology of the Harp Seal Pagophilus groenlandicus
TLDR
During a nutritional investigation on harp seals, the opportunity arose to survey red cell profiles in both feral and captive newborn and adult animals, and the findings are presented herein for their possible contribution to the literature on circulatory adjustments to diving in marine mammals.
