Microsatellites were used to conduct an analysis of paternity of Antarctic fur seals (Arctocephalus gazella) from Bird Island, South Georgia. At most, only 28% of pups at our study site could be assigned a father, even though the majority (approximat
Northern fur seals prefer cold water and spend a lot of time far out at sea, only returning to land to breed. Most of their breeding grounds are on islands in the northern Pacific. As with most seal species, the male northern fur seals arrive at the breeding grounds first and occupy a territory on the shore. The largest bulls take the best locations, usually in the middle of the beach. Females arriving to give birth move into the territory of a male. They seem to choose according to the location of the territory and the number of other females it contains, rather than by the bulls size. At this stage, the males - called bulls - will not feed for up to two months as they battle to mate with the cows, and will lose a considerable amount of body weight. Dominant northern fur seal bulls may establish harems numbering 40 to 50 cows. The dense underfur of this species, insulating the seals from the cold, consists of 60,000 individual hairs per square centimetre (350,000 per square inch).. ...
We tagged 82 lactating northern fur seals (Callorhinus ursinus) with tri-axial accelerometers and magnetometers on two eastern Bering Sea islands (Bogoslof and St. Paul) with contrasting population trajectories. Using depth data, accelerometer data and spectral analysis we classified time spent diving (30%), resting (~7%), shaking and grooming their pelage (9%), swimming in the prone position (~10%) and two types of previously undocumented rolling behavior (29%), with the remaining time (~15%) unspecified. The reason for the extensive rolling behavior is not known. We ground-truthed the accelerometry signals for shaking and grooming and rolling behaviors-and identified the acceleration signal for porpoising-by filming tagged northern fur seals in captivity. Speeds from GPS interpolated data indicated that animals traveled fastest while in the prone position, suggesting that this behavior is indicative of destination-based swimming. Very little difference was found in the percentages of time spent in the

Her love for marine mammals has also led her to study the vulnerable northern fur seal population, both in our New Balance Foundation Marine Mammal Center and on the Alaskan islands they call home. In 2010, she received a Cunningham Grant from the Aquarium to volunteer with the National Oceanic and Atmospheric Administration (NOAA) researchers who study northern fur seals on the remote Pribilof Islands, where they come each summer to breed and nurse their pups.. Although there are more than 600,000 northern fur seals, climate change, overfishing, and the now-illegal fur trade have diminished the population by more than 50% since the 1950s. To determine best practices for protecting the species, NOAA researchers, with the help of volunteers like Schilling, monitor the adult fur seals and pups on the islands and use sail drones to track the fish populations the fur seals rely on to survive.. "The problem the fur seals face now is that the food that theyre eating is low in caloric content," ...

High-density SNP arrays developed for humans and their companion species provide a rapid and convenient tool for generating SNP data in closely-related non-model organisms, but have not yet been widely applied to phylogenetically divergent taxa. Consequently, we used the CanineHD BeadChip to genotype 24 Antarctic fur seal (Arctocephalus gazella) individuals. Despite seals and dogs having diverged around 44 million years ago, 33,324 out of 173,662 loci (19.2%) could be genotyped, of which 173 were polymorphic and clearly interpretable. Two SNPs were validated using KASP genotyping assays, with the resulting genotypes being 100% concordant with those obtained from the high-density array. Two loci were also confirmed through in silico visualisation after mapping them to the fur seal transcriptome. Polymorphic SNPs were distributed broadly throughout the dog genome and did not differ significantly in proximity to genes from either monomorphic SNPs or those that failed to cross-amplify in seals. ...
Single nucleotide polymorphism (SNP) discovery is an important goal of many studies. However, the number of putative SNPs discovered from a sequence resource may not provide a reliable indication of the number that will successfully validate with a given genotyping technology. For this it may be necessary to account for factors such as the method used for SNP discovery and the type of sequence data from which it originates, suitability of the SNP flanking sequences for probe design, and genomic context. To explore the relative importance of these and other factors, we used Illumina sequencing to augment an existing Roche 454 transcriptome assembly for the Antarctic fur seal (Arctocephalus gazella). We then mapped the raw Illumina reads to the new hybrid transcriptome using BWA and BOWTIE2 before calling SNPs with GATK. The resulting markers were pooled with two existing sets of SNPs called from the original 454 assembly using NEWBLER and SWAP454. Finally, we explored the extent to which SNPs
Antarctic fur seal (Arctocephalus gazella) male opening its mouth. The male is much larger than the female, reaching a length of up to 2 metres and a weight of 120 kilograms. The males pelt is brown in colour, and includes a mane of shoulder fur. The external ears (pinnae) of a seal are also seen here. This seal ranges throughout the Southern Ocean that surrounds Antarctica, feeding mainly on krill in shallow waters at night. During the breeding season (from November to January) the males compete to secure a harem of females. Photographed on South Georgia. - Stock Image C007/2304
Few models are in place for analysis of extreme lactation patterns such as that of the fur seals which are capable of extended down regulation of milk production in the absence of involution. During a 10-12 month lactation period, female fur seals suckle pups on shore for 2-3 days, and then undertake long foraging trips at sea for up to 28 days, resulting in the longest intersuckling bouts recorded. During this time the mammary gland down regulates milk production. We have induced Cape fur seal (Arctocephalus pusillus pusillus) mammary cells in vitro to form mammospheres up to 900 μm in diameter, larger than any of their mammalian counterparts. Mammosphere lumens were shown to form via apoptosis and cells comprising the cellular boundary stained vimentin positive. The Cape fur seal GAPDH gene was cloned and used in RT-PCR as a normalization tool to examine comparative expression of milk protein genes (αS2-casein, β-lactoglobulin and lysozyme C) which were prolactin responsive. Cape fur seal ...
The MMC is currently closed to the public because it is constructing new pens, pools and buildings, including an extensive visitors center expected to open in the spring of 2008. But during this pupping season, which began in late February, theyve been promoting a "Leave Seals Be" campaign. Anyone who finds an apparently abandoned seal pup should keep their distance, not touch it and call the centers 24-hour response hotline at 415.289.SEAL. Generally, the person who notifies the center that an animal needs rescuing gets to name that animal. Seals, sea lions, whales, dolphins and sea otters have been named by CHP officers, firefighters, beachcombers, home owners and other community members. Odle2 from Sunnyvale was named for the police officer who arranged for her to be picked up by the MMC. There was already one Odle on the books, so she became Odle2. When she was brought in, she weighed a little over 10 pounds, and was considered to be in critical condition. As of Feb. 18, Odle2 weighs a ...

Cape Fur Seals, (Arctocephalus Pusillus Pusillus) can be found on the coastlines of southern Africa. They are listed on Appendix II of CITES. They have a natural mortality rate of around 30% and are at threat from a 90% loss of preferred habitat, entanglement, drowning in fisheries nets, marine pollution, disease, global warming and the continued persecution by the annual Namibian "cull." The Benguela Nino in 2006 resulted in the deaths of over 300 THOUSAND of these animals, the largest mass die-off of all marine mammals in recorded history. Although these are wild animals, they are generally friendly and curious by nature. ...
Seabirds are marine top predators and accumulate high levels of metals and metalloids in their tissues. Contamination by metals in the highly productive offshore region has become a matter of public concern. It is home to 80% of the seabird population in the U.S.A., 95% of northern fur seals (Callorhinus ursinus), and major populations of Steller sea lions (Eumetopias jubatus), walruses (Odobenus rosmarus) and whales. Here, the concentrations of eight heavy metals (Hg, Cd, Cr, Co, Ni, Cu, Zn and Pb) and a metalloid (As) in the liver and kidneys of the northern fulmar (Fulmarus glacialis), thick-billed murre (Uria lomvia), short-tailed shearwater (Puffinus tenuirostris), tufted puffin (Fratercula cirrhata) and horned puffin (Fratercula corniculata) collected in the Bering Sea were measured ...
The Australian fur seal (Arctocephalus pusillus doriferus) population has displayed a relatively slow rate of recovery since being hunted by commercial sealers during the early 19th century. Despite this, population abundance doubled in the past 2 - 3 decades, indicating that the population growth rate has recently increased. Yet, the factors influencing the populations dynamics are poorly understood, primarily because basic demographic rates are unknown. Female age, survival, fecundity, breeding and physiology were studied at Kanowna Island, Bass Strait, Australia, between 2003 - 2006 by conducting censuses and captures (n = 294). Mark-recapture estimates of pup production were used to validate direct pup counts, allowing a 9-year dataset to be used for calculation of the population growth rate (2.2% p.a.) and investigation of environmental influences on reproductive success. Annual pup production (x = 3108) was synchronous, with 90% of births occurring within 28 days of the median birth date ...

The investigation into the level and distribution of genetic variation in the Antarctic and subantarctic fur seals was conducted using two classes of molecular marker. The mitochondrial control region is a commonly used marker for investigation into population genetics issues, due in part to the relatively high rate of mutation. Microsatellites are highly variable regions within the nuclear genome, and with a bi-parental mode of inheritance, provide a natural complement to the maternally inherited mitochondrial genes. Given that historic records indicate both fur seal species had passed through population bottlenecks as a result of sealing, it was suspected that the current level of genetic variation may be low. This is because reduced levels of variation have been observed in other species that have passed through extreme population bottlenecks at some stage in the recent past (eg. the northern elephant seal, Mirounga angustirostris). Surprisingly, the nucleotide diversities of the Antarctic ...

Unlike other West Coast pinnipeds such as harbor seals and sea lions, northern fur seals are pelagic by inclination, meaning they spend most of their lives drifting with the ocean currents. They log only a few weeks a year on isolated islands to whelp and rear their young. Pups are quickly weaned, joining their parents to ply offshore waters in quest of fish and squid. ...

A neurosurgical team at Cummings School of Veterinary Medicine at Tufts University has successfully performed what is believed to be a first-of-its-kind brain surgery on a Northern fur seal named Ziggy Star in an attempt to address her worsening neurologic condition. Ziggy, an adult female, is recovering well at her permanent home at Mystic Aquarium in Mystic, Connecticut.. "The ability to successfully complete this procedure with many unknown factors is due in large part to the collaboration among colleagues at Cummings and Mystic," said Cummings lead neurosurgeon, Ane Uriarte, DVM, Diplomate of the European College of Veterinary Neurology. "The combined expertise and skills from all our areas of specialty-from neurosurgery to anesthesia and zoological medicine-was critical to this success.". Ziggy was first seen at the Henry and Lois Foster Hospital for Small Animals at Cummings Veterinary Medical Center at Tufts University in September for a condition that had progressed over several years ...
As with seabirds and fishes, the composition of the sanctuarys marine mammal community is a mix of permanent and seasonal residents as well as species that use these waters for shorter periods - either as a feeding destination or in transit during long-distance migratory journeys.. Californias central coast is located on a migration pathway between northern feeding grounds and temperate and tropical breeding areas for many marine mammal species. For example, gray whales traverse these waters on their annual migrations between Arctic feeding grounds and Mexican breeding areas; however, in some years, many gray whales will also over-summer in the sanctuary to feed.. Blue and humpback whales are seasonally abundant, migrating into the sanctuary during late spring, summer and fall to feed in its productive waters. Northern fur seals and California sea lions are also seasonally abundant, coming here to forage during the fall through the spring. Smaller cetaceans (e.g., several dolphin and porpoise ...
Hookworms are a leading cause of mortality in seal and sea lion pups. Researchers will investigate if ocean food availability as well as the genetic make-up and immune response in South American fur seal pups affect the severity of hookworm infections. The team will analyze 15 years of collected data on fur seals living on Guafo Island in southern Chile to investigate if changes in ocean sea surface temperature and productivity also are associated with changes in hookworm prevalence and mortality in pups. Identifying drivers for hookworm infections, including marine environment, genetics and immune responses in individual animals, will help researchers develop improved wildlife health programs for mitigating hookworms and other parasitic diseases in marine mammals.. ...

If youre out on local scenic roads at the crack of day, youre likely to see a posse of Crozet cyclists trailing slipstreams, winding like wind down the roads.. "Whos riding?" goes their nightly sign-up call. Meet-up is at The Mudhouse in Crozet at 6 a.m. Home plate, arrived at after an hour and covering some 18 to 20 miles, is Green House Coffee, where they pull in and stop neatly, as ducks settle on water. They grin with exhilaration. Their toes still have spring in them. They feel alive on their bikes, and when their feet touch the ground again, they flinch and must get used to gravity.. Theyre in snappy, slippery-looking cycling outfits they call kits. The kit the Crozet Cycling Club guys are wearing takes off from the Crozet crest, sporting an azure blue that seems to soar and, right at the wearers heart, a red medieval rose. The look is sort of classy. It was made by Cutaway, a local cycling clothing company operated by Phillip Robb, who is a cycling coach at Miller School, which has ...

The processing and dyeing of any clothing material must be carefully regulated to protect the environment. Again, nothing is 100% "green". Fur tanning ("dressing") and coloring, however, are relatively benign, as they must be, to preserve fur hairs and follicles. (By contrast, in leather tanning the hair is intentionally removed from the hide.). The main chemicals used to "dress" fur pelts are table salt, water, alum salts, soda ash, sawdust, cornstarch, lanolin and other natural ingredients. Small quantities of formaldehyde can be used to protect fur follicles during dressing or dyeing, and gentle acids (e.g., acetic acid, which is vinegar) activate the tanning process, but local environmental protection controls ensure that there are no harmful effluents. Excess fats are skimmed and even PH levels must be neutralized before wastewater is released. And because furs are available in an extraordinary range of natural colours, only a small proportion are dyed.. By contrast, up to one gallon of ...
In Kims defense, it has been reported that she only wears fur made from roadkill.

Vascular plant cover was near 100 % between 490 and 910 m, and dropped at both ends of the gradient (F3,19 = 10.27; P = 0.0003; Fig. 2B). On average, cover was greater in the palmar than in the remainder of the island (F191 = 7.461; P = 0.0072). Moss cover was largest between 600 and 950 m (F319 = 11.13; P = 0.0002; Fig. 2C).. We recorded a total of 3870 palms. Some of them were recorded in inaccessible areas below our lowest transect. Palm density increased rapidly from about 150 to 500 m, and dropped back to zero at 850 m (F4,4 = 18.45; P = 0.0076; Fig. 2D). A very similar pattern was observed if only palms occurring less than 200 m away from our set of transects are considered, with the only difference that no individuals occur below 430 m where the cliff starts (data not shown).. DISCUSSION. Our results confirm that species richness and vascular plant cover in the palmar were greater than those observed in the remainder of the island, and that there was a clear altitudinal zonation of the ...
