• The Measurement of Seagrass Photosynthesis Using PAM Fluorometry - Summary

  Australian Ocean Data Network (AODN)

  Photosynthetic activity of three seagrass species, Posidonia sinuosa, Posidonia australis and Halophila ovalis, growing in Cockburn Sound, Western Australia, was assessed using an underwater pulse amplitude modulated fluorometer (Diving-PAM). The study aimed…

• Effects of provisioning bottlenose dolphins in Cockburn Sound: injuries, entanglements, and changes to ranging and social behaviours

  Australian Ocean Data Network (AODN)

  Unpublished data and analyses from Rebecca Donaldson (1993-1997) and original data collected for the thesis (2000-2003) from Cockburn Sound were used to: 1) evaluate the link between high-risk behaviour by dolphins during provisioning interactions and rates of…

• Little Penguin (Eudyptula minor) foraging and travelling areas in Warnbro Sound and Comet Bay

  Australian Ocean Data Network (AODN)

  This dataset consists of points representing the daytime distribution of Little Penguins in Warnbro Sound and Comet Bay as observed during radio tracking (from air and land) surveys conducted within the metro area on the following dates: November 1996 (air and…

• Bottlenose Dolphins (Tursiops sp.) in the Swan Estuary

  Australian Ocean Data Network (AODN)

  The GPS locations of Bottlenose dolphins in the Swan River Estuary were recorded from October 2001 to June 2003 with the following fields: behaviour, date/time, location, nearest landmark, id's present, depth, feeding activity and the presence of tail slapping…

• Conservation Biology of Bottlenose Dolphins (Tursiops sp.) in Perth Metropolitan Waters - Summary

  Australian Ocean Data Network (AODN)

  The aim of this study was to assess the effects of human-induced habitat change and illegal feeding on the residential sub-population of ~75 bottlenose dolphins in Cockburn Sound, Western Australia by using a variety of sampling approaches from 2000-2003.

• Factors influencing the acquisition of an attraction response to human provisioning by bottlenose dolphins in Cockburn Sound

  Australian Ocean Data Network (AODN)

  The contribution of four factors to the acquisition of attraction responses to human provisioning by dolphins in Cockburn Sound: 1) individual patterns in the use of high boat density areas; 2) age-class; 3) sex; and 4) close associations with 'experienced'…
