Variation in corticosterone responses to handling within and between Adelie penguins, Ross IslandEntry ID: K034_2001_2005_NZ_4
Abstract: Corticosterone responses to handling and behavioural responses to the approach of a person are two responses of adelie penguins to potential stressors. We measured these responses in different birds in 2001-2002 season, and in the following season (2002-2003) examined whether there is a relationship between the endocrine and behavioural responses of individual birds. Behavioural responses were measured in 24 incubating birds with blood sample collected the following day for corticosterone measurements. The behavioural response was repeated on 4 other occasions to determine the amount of variation in response of individual birds.

Quality The raw data is hormone concentrations and behaviour measurements. These data form the basis of ongoing publications, and are not available in any form.
The plasma samples are in the private laboratory freezers at the Institute of Veterinary, Animal and Biomedical Sciences, Massey University, Palmerston North, New Zealand. It is possible to provide plasma samples once the investigators measurements are made.
Access Constraints The data is only available through contact with the investigator.
