Long-term changes in the population status of Southern Elephant Seals (Mirounga leonina) at Macquarie Island, 1952-2005. Abstracts of the SCAR Open Science Conference, Hobart, 12-14 July 2006, 2006 (Ref: 12525)
Category 3: Abstract

The southern elephant seal (Mirounga leonina) population at Macquarie Island represents … about 10% of the world’s population. The number of adult females breeding at the island has … decreased substantially since the first whole island census was conducted in 1952.

The annual numbers of Leopard Seals (Hydrurga leptonyx) sighted at Macquarie Island (over 56 years) are correlated significantly with periodic flux of sea-ice concentration south-east of the island. Abstract of the SCAR Open Science Conference, Hobart, 12-14 July 2006, 2006 (Ref: 12524)
Category 3: Abstract

This paper provides the first evidence to relate Leopard Seal numbers with sea-ice … concentrations in a region of the Eastern Antarctic pack ice and to propose a biological … mechanism (krill availability) to link the two. Leopard seals have been periodic, and sometimes numerous…

This study addresses the consequences of repeated … human handling on the survival of an endangered phocid, the southern elephant seal and the implications for wildlife … research. Southern elephant seal pups were repeatedly … handled during the first six weeks of their lives.

Comparison of southern elephant seal populations, and observations of a population on a demographic knife-edge. Marine Ecology Progress Series, 2005 (Ref: 12283)
Category 1: Peer-reviewed literature

The dynamics of animal populations are determined by several key demographic parameters, which vary over time with resultant changes in the status of the population. When managing … declining populations, the identification of the parameters that drive such change are a high priority…

Movements of adult female Weddell seals during the winter months. Polar Biology., 2005 (Ref: 12231)

Mass of weaned elephant seal pups in areas of low and high human presence. Polar Biology, 2001 (Ref: 9617)
Category 1: Peer-reviewed literature

On sub-Antarctic Macquarie Island, we examined pup weaning mass of southern elephant seals in relation to human presence. Pup weaning mass was previously found to be positively associated with 1st-year survivorship. Weaned pups were weighed in a remote area, Middle Beach…
