6. The respiratory and metabolic activity of a nematode worm found in the body cavity of Antarctic fish and Weddell seals [K057_1999_2000_NZ_1]
The respiratory ability of a nematode worm at different temperatures up to 38?C that live in the body cavity of Antarctic fish and ultimately with the final host being a Weddell seal was examined. ...


7. Metabolic consequences of diving in the Weddell seal (Leptoychotes weddelli) [K065_2002_2003_NZ_1]
To achieve a greater understanding of metabolic efficiency during diving, it is important to establish the degree of metabolic suppression (reduction of oxygen consumption) at the cellular level, ...


8. The energy expenditure by mother Weddell seals during the suckling period [K071_1996_1997_NZ_1]
Weddell seals are well adapted polar animals. They give birth to pups in the Antarctic summer when they haul out onto the ice. While feeding their pups, they have a massive fasting weight loss (and ...


9. Biological survey of the Balleny Islands [K407_2000_2001_NZ_1]
US coastguard helicopters were used to survey bird, seal and plant populations of the three main islands and islets of the Balleny Islands, located off the coast of Antarctica, for birds and seal ...


10. Food chain investigations at White Island: seal survey, seasonal trends in phytoplankton populations, ocean environmental factors, zooplankton biomass and fish diet, age and growth studies [K014_1976_1977_NZ_1]
A population of Weddell Seals at White Island (some 20km from the edge of the Ross Ice Shelf) was/is thought to be a sub-population that does not migrate to the pack ice in the non-breeding season ...


11. Survey of the mammals and birds occurring at Cape Bird, 1977-1980 [K014_1977_1978_NZ_2]
A general survey of the mammals and birds occurring was carried out at Cape Bird 1977-1981 and at Cape Hallett 1982-1983. No previous work has been carried out on mammals in these areas. Short, frequent ...


12. The breeding behaviour (territorial behaviour, male quality, movement and mating success) of male and female Weddell seals in relation to reproductive success during the breeding season [K027_1997_2001_NZ_1]
The breeding behaviour of the Weddell seal, Leptonychotes weddelli at the Turtle Rock colony in McMurdo Sound was studied over four breeding seasons. The aim was to quantify the male and female behaviour ...


13. Underwater recordings of Weddell seal calls recorded as a indication of male attributes, both inter and intra-sexual interactions during the breeding season in Weddell seals [K027_1997_2001_NZ_2]
To determine if male weddell seal calls reveal information on male attributes, recordings of major Weddell call types from all of the sampled males at the Turtlerock colony was correlated with measurements ...
