Progress Code: completed Statement: This indicator is now OBSOLETE. These data are no longer archived in this location, and are therefore not up-to-date. Censuses of breeding adults are performed and long term trends are determined. Integration with other long term datasets is currently underway through international collaborations, allowing for comparisons among sites at regional and ecosystem scales. Some analyses and their interpretations have been published (see references), and current analyses will examine population data as they are compiled. This indicator is no longer maintained, and is considered OBSOLETE. INDICATOR DEFINITION Breeding populations of Adelie penguins at Davis, Mawson and Casey (including Shirley Island and Whitney Point). TYPE OF INDICATOR There are three types of indicators used in this report: 1. Describes the CONDITION of important elements of a system; 2. Show the extent of the major PRESSURES exerted on a system; 3. Determine RESPONSES to either condition or changes in the condition of a system. This indicator is one of: CONDITION RATIONALE FOR INDICATOR SELECTION The breeding population of Adelie penguins is related to resource availability (nesting space and food), behavioural mechanisms (immigration/emigration and breeding effort/success) in addition to climate change and human impacts (fisheries, tourism, pollution, disturbance). Monitoring these colonies and interpretation of the data provides information on changes in the Antarctic ecosystem. DESIGN AND STRATEGY FOR INDICATOR MONITORING PROGRAM Spatial scale: Colonies near Australian Stations - Casey (lat 66 deg 16' 54.5" S, long 110 deg 31' 39.4" E) Davis (lat 68 deg 34' 35.8" S, long 77 deg 58' 02.6" E) Mawson (lat 67 deg 36' 09.7" S, long 62 deg 52' 25.7" E) All colonies on - Shirley Island (lat 66 deg 16' 55.9" S, long 110 deg 29' 17.9" E) and Whitney Point (lat 66 deg 15' 08.6" S, long 110 deg 31' 40.1" E) Frequency: Annual surveys at Shirley Island and Whitney Point. Other colonies every 2-3 years, depending on ...
