23-May-2002	Adelie penguin populations in East Antarctica are presently showing long-term (30-50 year) increases at regional scales. While some populations show inter-annual variability, regional populations (for example, the Mawson coastline) are increasing in the longer term. For the Casey region, the total breeding population has more than trebled since the early 1960s. Similar long-term increases have been reported by French researchers for Adelie Land. Mawson Coast breeding populations (Woehler et al., 1989): Giganteus Island: The breeding population increased between 1972-73 and 1981-82, and then decreased to less then that of 1972-73 in 1988-89. Verner Island: The breeding population at Verner Island has shown a long-term (15-year) decrease. This decrease is approaching 40% between 1972-73 and 1988-89. Rookery Island: The population increased between 1972-73 and 1981-82, and remained stable between 1981-82 and 1988-89. Rookery Island 2: The breeding population increased between 1972-73 and 1981-82, and then decreased to less then that of 1972-73 in 1988-89. Rookery Island 5: The data indicate a relatively stable population between 1972-73 and 1981-82, and a slight decrease to 1988-89. Rookery Island 6: As with Rookery Island 2, the population increased between 1972-73 and 1981-82, and has since declined. The photographic coverage in 1981-82 is incomplete, with only 90% of the island photographed. Colonies were larger in 1981-82 than 1988-89. Rookery Island 9: The population increased between 1972-73 and 1981-82, and remained stable between 1981-82 and 1988-89. Casey region breeding populations: Shirley Island: The breeding population has not changed significantly since 1968. Large inter-annual variations in breeding population size are evident. Whitney Point: The breeding population at Whitney Point has more than quadrupled between 1959 and 1995. This increase is reflected both in an increase in the populations of existing colonies and in the formation of new colonies. Reference Woehler, E.J., Johnstone, G.W. and Burton, H.R.
