Abstract:
The dental pathology of pinnipeds has been well studied with periodontal disease the most common dental pathology accounting for 19.4–91.8 per cent of all dental pathologies. An eight-month-old stranded South African fur seal (Arctocephalus pusillus pusillus) was rescued from the south coast of South Africa; during his rehabilitation process his handlers noticed the absence of his left maxillary canine tooth (204). Eleven years later, during a health examination, the veterinarian upon closed examination could visualise approximately 5 mm of a tooth crown in the area where tooth 204 should have been. A presumed diagnosis of a dentigerous cyst was made based on the radiological findings. Surgery was performed to surgically extract 204 and enucleate the cyst lining. The histological analysis of the enucleated cyst lining confirmed the first reported case of a dentigerous cyst in a marine mammal.

Abstract:
While marine top predators can play a critical role in ecosystem structure and dynamics through their effects on prey populations, how the predators function in this role is often not well understood. In the Benguela region of southern Africa, the Cape fur seal ( Arctocephalus pusillus pusillus ) population constitutes the largest marine top predator biomass, but little is known of its foraging ecology other than its diet and some preliminary dive records. Dive information was obtained from 32 adult females instrumented with dive recorders at the Kleinsee colony (29°34.17′ S, 16°59.80′ E) in South Africa during 2006–2008. Most dives were in the depth range of epipelagic prey species (less than 50 m deep) and at night, reflecting the reliance of Cape fur seals on small, vertically migrating, schooling prey. However, most females also performed benthic dives, and benthic diving was prevalent in some individuals. Benthic diving was significantly associated with the frequency with which females exceeded their aerobic dive limit. The greater putative costs of benthic diving highlight the potential detrimental effects to Cape fur seals of well-documented changes in the availability of epipelagic prey species in the Benguela.

Abstract:
The annual reproductive cycle of the female Cape fur seal (Arctocephalus pusillus pusillus) was described by noting monthly gross changes in ovaries from 159 females, histological changes in 46 females and placental scars in 119 females. The size and weight of an ovary containing a corpus luteum was significantly greater than that of an ovary containing a corpus albicans for most of the year, the latter only approaching, or exceeding the former during the breeding season. Follicular activity initially increased in ovaries containing either a corpus luteum or a corpus albicans; however, it declined in the ovary containing a corpus luteum after implantation, while in that containing a corpus albicans it increased, reaching a maximum in December of 32.0 ± 10.08 follicles, averaging 5.41 ± 0.73 mm. The corpus luteum increased in size following ovulation, attaining a maximum size of 22.28 ± 3.38 mm in August (eight months after ovulation). Thereafter, it gradually decreased in size, generally becoming invisible to the naked eye by 30–32 months after ovulation. Luteal cells increased until seven months after ovulation, reaching a maximum size of 34.36 ± 1.26 μm before regressing, disappearing from the corpus luteum by 18 months after ovulation. Using placental scarring and CA counts in 119 females, a pregnancy rate of 77.4% was calculated, with 6.5% abortions and 16.1% non-implantations making up the remainder.

Abstract:
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 population’s 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 of 23 November. Births occurred earlier in years when pup production and female body condition were high and these factors were correlated with local oceanographic indicators, suggesting that reproductive success is constrained by environmentally-mediated nutritional stress.
Pregnancy was assessed by blood plasma progesterone radioimmunoassay and the pupping status of the same females was observed during breeding season. Despite high mid-gestation pregnancy rates (x = 84%), the birth rate was lower than in other fur seals (x = 53%), suggesting that late-term abortion is common. Lactating females were less likely to pup, indicating that nutrition may be insufficient to support concurrent lactation and gestation.
Age and morphometric data were used to construct body growth, age structure and survivorship models. Adult female survival rates were similar to those of other fur seals (x = 88.5%). A life table was constructed and its age-specific survival and fecundity rates used in a Leslie-matrix model to project the population growth rate (2.2% p.a.) and determine the relative influence of each parameter. The abundance of female non-pups was 6 times greater than that of female pups, which is approximately 50% higher than previous conversion factors used to extrapolate population abundance from pup censuses in Australian fur seals. However, if the non-pup sex ratios of other otariids are considered, the pup:population conversion factor is 4.5.
Compared to a study performed before the recent population increase, the modern population displays similar body growth and fecundity rates but higher survival rates. This suggests that recent population growth resulted from a relaxation of hunting and/or predation mortality rather than from increased food availability. The low population growth rate is attributed to a low birth rate associated with nutritional stress, yet despite this, body growth occurs rapidly. Such characteristics are typical of sea lions rather than fur seals, perhaps because Australian fur seals employ the typical sea lion strategy of using benthic foraging to exploit a continental shelf habitat. The effect of ecological niche on population dynamics in the Otariidae is discussed.

Abstract:
The Cape fur seal Arctocephalus pusillus pusillus colony at the Robberg Peninsula, Plettenberg Bay, on the south-east coast of South Africa, was driven to extirpation by indiscriminate harvesting by the late 1800s and seals only began to recolonise this site in the 1990s. This study describes the recolonisation process from 2000 to 2009, exploring within- and between-year variation in the number of seals using the site. Numbers increased over the study period from less than 300 animals to over 3 100. Year and month were important in explaining variability in seal counts, whereas sea condition, time of day and lunar phase had minimal explanatory power. Within-year variation in seal counts decreased during the study period, which may indicate an increasing proportion of resident (as opposed to transient) seals in the colony. However, the colony is currently still in a transition phase with a low ratio of breeding to non-breeding animals and low numbers of pups born on the colony (currently still < 100 per year). The influx of seals to the Robberg area may be associated with an increase in prey availability in the area. The relative protection afforded by the Nature Reserve status of the Robberg Peninsula and the existence of a Marine Protected Area adjacent to it are likely to contribute to the growth of this colony. However, human interference associated with fishing and/or ecotourism on the Peninsula may prevent the colony from developing into a breeding colony. Faecal (scat) sampling was employed to study the diet of this increasing seal population at Robberg. Species composition and size of prey were determined, temporal variation in the diet was explored, and the potential for competition between seals and the fisheries around Plettenberg Bay was investigated. Of the 445 scats collected, 90 % contained hard prey remains. These comprised of 3 127 identified otoliths representing 15 teleost prey species, 25 cephalopod beaks representing three 6 species and three feathers representing two bird species. The seals' most important prey species in terms of numerical abundance and frequency of occurrence in the diet were anchovy, sardine, horse mackerel, sand tongue-fish and shallow-water hake (in decreasing order of importance). The proportion of anchovy in the diet increased during the study period, while sardine decreased. Sardine was the only species that increased significantly in the diet during the upwelling season. Little evidence was found of direct competition between seals and linefisheries in Plettenberg Bay, both in terms of prey species composition and quantities consumed. Scat sampling in seals holds promise as a method to track long-term changes in prey species availability. The conservation and management of this colony are discussed in light of the research findings.

Abstract:
Odor discrimination ability was tested in four female South African fur seals (Arctocephalus pusillus pusillus) using a food-rewarded two-choice instrumental conditioning paradigm. The seals’ ability to distinguish between members of homologous series of aliphatic ketones (2-butanone to 2-heptanone) and alcohols (1-butanol to 1-heptanol) was assessed. The results showed that three out of four seals successfully discriminated between all of their stimulus combinations in both classes of odorants. One seal succeeded to reach the discrimination criterion with all 2-ketones but failed with all 1-alcohols. No significant correlation between odor discrimination performance and structural similarity of the odorants in terms of differences in carbon chain length was found in either of the two chemical classes. Furthermore, it was found that the 2-ketones were significantly better discriminated than the 1-alcohols. The fact that both classes of odorants are known to be present in the natural environment of seals provides a possible explanation as to why most of the seals were able to successfully discriminate between them. The results of the present study support the notion that the sense of smell may play an important role in behavioral contexts such as social communication, foraging and reproductive behavior of fur seals.

Com o objetivo de identificar parasitas e doenças parasitárias de pinípedes que vivem sob cuidados humanos em Portugal, realizou-se um estudo sobre parasitoses cardiopulmonares e gastrointestinais na coleção de pinípedes pertencente ao Zoomarine – Mundo Aquático S.A., que se situa no Algarve. No total, foram colhidas 19 amostras sanguíneas e 79 amostras fecais de 20 indivíduos de três espécies: foca-comum (Phoca vitulina) (n=6), foca-cinzenta (Halichoerus grypus) (n=2) e leão-marinho-californiano (Zalophus californianus) (n=6) e de uma subespécie, otária-sul-africana (Arctocephalus pusillus pusillus) (n=6). As amostras sanguíneas foram analisadas utilizando o teste rápido de antigénio WITNESS®Dirofilaria e a técnica de Knott modificada. Para as amostras fecais utilizaram-se as técnicas de McMaster, Flutuação de Willis, Sedimentação em meio saturado, Técnica de Baermann modificada e esfregaços fecais corados pela técnica de Ziehl-Neelsen. O teste rápido foi positivo em duas focas-comuns e detetaram-se microfilárias correspondentes a D. immitis numa otária-sul-africana. As análises fecais, na sua totalidade, foram consideradas negativas. Realizou-se também a identificação morfológica de nemátodes encontrados em necrópsias de duas otárias-sul-africanas e seu exame histopatológico correspondente. Os vermes adultos encontrados no coração e artéria pulmonar foram identificados como D. immitis, tornando-se este trabalho, no conhecimento da autora, o primeiro registo em A. p. pusillus a nível mundial e também o primeiro registo da infeção por este nemátode em pinípedes em Portugal. Atendendo a que o Algarve é considerado uma região endémica para este parasita e sendo a Dirofilariose uma doença re-emergente nesta e noutras zonas do País, é importante dar uma continuidade a este e outros estudos sobre parasitas transmissíveis por vetores, para melhor compreender os efeitos desta e outras parasitoses em pinípedes em ambiente zoológico.
ABSTRACT - Cardiopulmonary and Gastrointestinal Parasites in Pinnipeds in a Zoological Context - In order to identify parasites and parasitic diseases of pinnipeds that live under human care in Portugal, we performed a study on cardiopulmonary and gastrointestinal parasites in the pinniped group belonging to Zoomarine – Mundo Aquático S.A., which is located in the Algarve. In total, 19 blood samples and 79 fecal samples were collected from 20 individuals from three species: common seal (Phoca vitulina) (n=6), grey seal (Halichoerus grypus) (n=2) and California sea lion (Zalophus californianus) (n=6) and from one subspecies, South African fur seal (Arctocephalus pusillus pusillus) (n=6). Blood samples were tested using a Dirofilaria immitis commercial antigen test (WITNESS®Dirofilaria) and modified Knott's technique. Fecal samples were tested using McMaster technique, Willis Flotation, Sedimentation, modified Baermann technique and fecal smears stained by Ziehl-Neelsen technique. Two samples from common seals tested positive in the antigen test and one sample from a South African fur seal showed microfilariae consistent with D. immitis. All the fecal samples tested negative. The morphological identification of worms found in necropsies of two South African fur seals was also performed, as well as, the corresponding histopathological analysis. The adult worms found in the heart and pulmonary artery at the necropsies, were identified as D. immitis, and to the author’s knowledge, this work is the first world report of D. immitis infection in A. p. pusillus and the first report of this nematode in a pinniped group in Portugal. As the Algarve is considered an endemic area for this parasite and as Dirofilariasis is a reemergent disease in several areas of the country, it is important to continue researching this and other vector-borne diseases in order to fully understand the effects of parasitic diseases in pinnipeds in a zoological context.

Abstract:
The sense of smell in marine mammals is traditionally thought to be poor. However, increasing evidence suggests that pinnipeds may use their sense of smell in a variety of behavioral contexts including communication, foraging, food selection, and reproduction. Using a food-rewarded two-choice instrumental conditioning paradigm, I assessed the ability of South African fur seals, Arctocephalus pusillus, to discriminate between 12 enantiomeric odor pairs, that is, between odorants that are identical in structure except for chirality. The fur seals significantly discriminated between eight out of the twelve odor pairs (according to p < 0.05, with carvone, dihydrocarvone, dihydrocarveol, limonene oxide, menthol, beta-citronellol, fenchone, and alpha-pinene), and failed with only four odor pairs (isopulegol, rose oxide, limonene, and camphor). No significant differences in performance were found between the animals (p > 0.05). Cross-species comparisons between the olfactory performance of the fur seals and that of other species previously tested on the same set of odor pairs lend further support to the notion that the relative size of the olfactory bulbs is not a reliable predictor of olfactory discrimination abilities. The results of the present study suggest that sense of smell may play an important and hitherto underestimated role in regulating the behavior of fur seals.

Abstract:
Gli squali bianchi sono tra i più importanti predatori dei Pinnipedi (Klimley et al., 2001; Kock, 2002). La loro principale strategia di caccia consiste nel pattugliare le acque circostanti ad una colonia di otarie e nell’attaccarle quando queste sono in movimento, mentre si allontanano o avvicinano all’isola (Klimley et al., 2001; Kock, 2002). Tuttavia, la strategia e la dinamica della predazione osservate anche in relazione al ciclo riproduttivo della preda e le tattiche comportamentali messe in atto dalla preda per ridurre la probabilità di predazione, e quindi diminuire la sua mortalità, sono ancora poco conosciute. Con questo studio, effettuato nell’area di Seal Island all’interno della baia di Mossel Bay in Sud Africa, abbiamo cercato di definire proprio questi punti ancora poco conosciuti. Per studiare la strategia e le dinamica di predazione dello squalo bianco abbiamo utilizzato il sistema di monitoraggio acustico, in modo da poter approfondire le conoscenze sui loro movimenti e quindi sulle loro abitudini. Per dare un maggiore supporto ai dati ottenuti con la telemetria acustica abbiamo effettuato anche un monitoraggio visivo attraverso l’attrazione (chumming) e l’identificazione fotografica degli squali bianchi. Per comprendere invece i loro movimenti e le tattiche comportamentali messi in atto dalle otarie orsine del capo per ridurre la probabilità di predazione nella baia di Mossel Bay, abbiamo utilizzato il monitoraggio visivo di 24 ore, effettuato almeno una volta al mese, dalla barca nell’area di Seal Island. Anche se gli squali bianchi sono sempre presenti intorno all’isola i dati ottenuti suggeriscono che la maggior presenza di squali/h si verifica da Maggio a Settembre che coincide con l’ultima fase di svezzamento dei cuccioli delle otarie del capo, cioè quando questi iniziano a foraggiare lontano dall'isola per la prima volta; durante il sunrise (alba) durante il sunset (tramonto) quando il livello di luce ambientale è bassa e soprattutto quando la presenza delle prede in acqua è maggiore. Quindi possiamo affermare che gli squali bianchi a Seal Island prendono delle decisioni che vanno ad ottimizzare la loro probabilità di catturare una preda. I risultati preliminari del nostro studio indicano anche che il numero di gruppi di otarie in partenza dall'isola di notte sono di gran lunga maggiori di quelle che partono durante il giorno, forse questo potrebbe riflettere una diminuzione del rischio di predazione; per beneficiare di una vigilanza condivisa, le otarie tendono in media a formare gruppi di 3-5 o 6-9 individui quando si allontanano dall’isola e questo probabilmente le rende meno vulnerabili e più attente dall’essere predate. Successivamente ritornano all’isola da sole o in piccoli gruppi di 2 o 3 individui. I gruppi più piccoli probabilmente riflettono la difficoltà delle singole otarie a riunirsi in gruppi coordinati all'interno della baia.
