Abstract The aim of this study was to describe growth, determine age at sexual maturity and investigate the condition of bearded seals (Erignathus barbatus) collected in the fjords of Spitsbergen, Svalbard, Norway. Morphometric data, teeth and sex organs were collected from 110 animals. Age was determined by reading the cementum layers in hard longitudinal sections of canine teeth. Sexual maturity in males was determined according to the size of the testes and bacula. Females were defined as… Expand

Growth and age at sexual maturity of South American sea lions
TLDR
Information on ASM and growth of O. flavescens will improve the development of population dynamics models, to investigate the impact of recovering sea lions populations on its marine environment, as well as its trophic interactions with commercial fisheries. Expand
Feeding habits of bearded seals (Erignathus barbatus) from the Svalbard area, Norway
TLDR
It is shown that in the Svalbard area bearded seals are benthic feeders and utilise a wide variety of organisms. Expand
Body condition as an index of winter foraging success in crabeater seals (Lobodon carcinophaga)
TLDR
By autumn, adult seals have replenished their energy stores following reproduction and molt, and the absence of seasonal variation in adults indicates that seals are successfully foraging throughout winter. Expand
Behavioural ontogeny of bearded seals Erignathus barbatus through the first year of life
TLDR
Bearded seal pups seem to be physiologically and behaviourally well developed by the time they are 2 mo old, which suggests that they continue to fine-tune their aquatic and other life-skills well past the end of the first year of life. Expand
Seasonal changes in the ovarian structure of the cape fur seal (Arctocephalus pusillus pusillus)
TLDR
The annual reproductive cycle of the female Cape fur seal was described by noting monthly gross changes in ovaries from 159 females, histological changes in 46 females and placental scars in 119 females. Expand
Individual variability in diving, movement and activity patterns of adult bearded seals in Svalbard, Norway
Bearded seals are one of the least studied Arctic marine mammals, despite their circumpolar distribution and importance as a resource to Inuit communities. In this study, adult bearded sealsExpand
A comparison of ringed and bearded seal diet, condition and productivity between historical (1975–1984) and recent (2003–2012) periods in the Alaskan Bering and Chukchi seas
TLDR
Ringed seals in the Alaskan Bering and Chukchi seas have adjusted to changes in diet, are growing faster and possibly weaning more pups in the recent compared to the historic period, and patterns are less evident for bearded seals. Expand
Long-term mating tactics in an aquatic-mating pinniped, the bearded seal, Erignathus barbatus
TLDR
It appears that although males can alter their mating tactics as circumstances change, only a few do so and mating tactics tend to show long-term stability in vocal characteristics, strong site fidelity and periods of tenure that cover a significant proportion of the male's adult life span. Expand
DEVELOPMENT OF DISPLAY BEHAVIOR IN YOUNG CAPTIVE BEARDED SEALS
TLDR
Individual capacity for vocal production appears to develop gradually, showing plasticity in form development over time in captive bearded seals. Expand
Diet composition of polar bears in Svalbard and the western Barents Sea
TLDR
It is believed that different patterns of space use by different bears may result in geographic variation of diet within the same population, and bearded seals are an important dietary item for polar bears in the western Barents Sea. Expand

Some Aspects of Growth and Reproduction of the Bearded Seal, Erignathus barbatus (Erxleben)
TLDR
This preliminary study is based on material from 113 specimens from the eastern Canadian Arctic and finds the female increases her length by about 33% in the first year and reaches about 91% of her final length at puberty, at 6 years; these figures are somewhat larger than expected from the growth patterns of other Pinnipedia.

Population parameters of ringed seals (Phoca hispida Schreber, 1775) in the Svalbard area
TLDR
Samples were taken from 284 ringed seals in the Svalbard area during April–July 1981 and March–April 1982 and showed that 63, 75, and 80% of 5-, 6-, and 7-year-old animals, respectively, were sexually mature. Expand
Seasonal and developmental changes of reproductive organs of male ringed seals (Phoca hispida) in the Svalbard area
TLDR
It is suggested that some testicular growth and a seasonal cycle in testes growth occur before the testes become functional endocrinologically, and that the primary event leading to puberty in ringed seals is an age-dependent shift in metabolic processes, directing a larger percentage of available energy towards the reproductive organs.

TLDR
It is shown that in the Svalbard area bearded seals are benthic feeders and utilise a wide variety of organisms. Expand
Evaluation of Body Condition in the Northwest Atlantic Harp Seal (Phoca groenlandica)
TLDR
Body condition in 315 harp seals obtained between 1988 and 1991 was evaluated, with pregnant females having heavier sculps than males in winter and pregnant females in winter having higher percent lipid in muscle than males. Expand

Birth-Site Characteristics and Prenatal Molting in Bearded Seals (Erignathus barbatus)
In Svalbard, Norway, bearded seals give birth on small, first-year, ice flows in the free-floating packice or on similarly sized white, glacial-ice areas frozen into gray, land-fast ice. Sites of theExpand
Growth and condition in the Northwest Atlantic harp seal
TLDR
It is indicated that harp seals collected in 1988-1992 were in poorer condition than animals collected during 1976-1979, which suggests a decline in available resources and the possibility of differences arising from sampling bias cannot be excluded. Expand
Seasonal changes in body mass and body composition of ringed seals (Phoca hispida) on Svalbard
TLDR
It is suggested that the seasonal body mass changes are mostly due to changes in body fat content, and found no evidence of significant changes in core mass in adult seals. Expand
Seasonal changes in food intake of harp seals (Phoca groenlandica) at 69°N
TLDR
Food intake, body mass, and compartmental growth were recorded for 12 mo in four captive 2–4-yr-old male harp seals exposed to an artificial light regime that closely resembled natural day length at 69° in early May before molting. Expand
