| plasma biochemical values of clinically-normal australian sea lions (neophoca cinerea). | seventeen biochemical constituents were assayed in the blood plasma of clinically-normal australian sea lions (neophoca cinerea). the sea lions formed part of a breeding colony which inhabits the southern coast of kangaroo island, south australia. little variation was found in any of the values obtained from animals of different age and sex. the results were compared with values published for california sea lions (zalophus californianus), northern fur seals (callorhinus ursinus), harbor seals (p ... | 1979 | 459034 |
| haematology of the australian sea lion, neophoca cinerea. | the haematology of the australian sea lion neophoca cinerea was studied in a breeding colony on kangaroo island, south australia. the methods used to catch and restrain the animals are described and the haematology of 38 animals of varying age and sex groups is recorded. total values for both erythrocytes and leucocytes were similar to those of other marine mammals and were in the ranges of 4.77 to 6.08 x 10(6) mm3 and 6.3 to 14.6 x 10(3) mm3, respectively. erythrocytes volumes were very large, ... | 1980 | 7373720 |
| entanglement of australian sea lions and new zealand fur seals in lost fishing gear and other marine debris before and after government and industry attempts to reduce the problem. | in recent years, australian governments and fishing industry associations have developed guiding principles aimed at reducing the impact of fishing on non-target species and the benthos and increasing community awareness of their efforts. to determine whether they reduced seal entanglement in lost fishing gear and other marine debris, we analysed australian sea lion and new zealand fur seal entanglement data collected from kangaroo island, south australia. contrary to our expectations, we found ... | 2004 | 15234872 |
| comparison of helicobacter spp. genetic sequences in wild and captive seals, and gulls. | helicobacter species are widely distributed in the gastrointestinal system of humans and many animal taxa. investigations of natural infections are essential to elucidating their role within the host. the feces of fur seals arctocephalus pusillus doriferus and sea lions neophoca cinerea from 3 separate captive populations, as well as a wild colony from kangaroo island, australia, were examined for the occurrence of helicobacter spp. the feces from several wild silver gulls larus novahollandiae w ... | 2005 | 16060262 |
| ontogeny of diving behaviour in the australian sea lion: trials of adolescence in a late bloomer. | 1. foraging behaviours of the australian sea lion (neophoca cinerea) reflect an animal working hard to exploit benthic habitats. lactating females demonstrate almost continuous diving, maximize bottom time, exhibit elevated field metabolism and frequently exceed their calculated aerobic dive limit. given that larger animals have disproportionately greater diving capabilities, we wanted to examine how pups and juveniles forage successfully. 2. time/depth recorders were deployed on pups, juveniles ... | 2006 | 16637989 |
| uncinaria sanguinis sp. n. (nematoda: ancylostomatidae) from the endangered australian sea lion, neophoca cinerea (carnivora: otariidae). | this study investigates the identity of hookworms parasitising the australian sea lion, neophoca cinerea (péron), from three colonies in south australia, australia. the australian sea lion is at risk of extinction because its population is small and genetically fragmented. using morphological and molecular techniques, we describe a single novel species, uncinaria sanguinis sp. n. (nematoda: ancylostomatidae). the new species is most similar to hookworms also parasitic in otariid hosts, uncinaria ... | 2014 | 25065131 |
| epidemiology of hookworm (uncinaria sanguinis) infection in free-ranging australian sea lion (neophoca cinerea) pups. | understanding the fundamental factors influencing the epidemiology of wildlife disease is essential to determining the impact of disease on individual health and population dynamics. the host-pathogen-environment relationship of the endangered australian sea lion (neophoca cinerea) and the parasitic hookworm, uncinaria sanguinis, was investigated in neonatal pups during summer and winter breeding seasons at two biogeographically disparate colonies in south australia. the endemic occurrence of ho ... | 2014 | 25056940 |
