Spinner dolphin time-series behavioural data

Time series behavioural data used to model the temporal partitioning of the daily behavioural activities of spinner dolphins in Hawaii

Mark_files

In Mark_files.zip, there are two files to be used in Mark program, although the extension will need to be changed to .inp. In both files, each row represents an individual. In the file Mark_file_3States, 0 indicated no capture; 1 = the individual was observed in the Swan Canning Riverpark; 2 = the individual was observed in the Cockburn Sound/Owen Anchorage; and 3 = the individual was observed in Gage Roads. In the file Mark_file_2States, 0 indicated no capture; A = the individual was observed in the Swan Canning Riverpark; B = the individual was observed in the Coastal waters (Cockburn Sound/Owen Anchorage and Gage Roads combined)

Capture-recapture models fitted to the capture histories of all juvenile and adult dolphins combined estimate parameters for population size (N), apparent survival (φ), temporary emigration (γ'', γ') and capture probability (p).

<p>Capture probability was allowed to vary with time between primary sampling periods and capture and recapture probability were assumed equal. Akaike information criterion corrected for small sample size (AICc) and was used to determine the best fitting model (in bold below). The notation ‘.’ indicates that a given parameter was kept constant and <i>t</i> indicates that a given parameter was allowed to vary with time.</p><p>φ Phi denotes survival.</p><p>p probability of capture.</p><p>c probability of recapture.</p><p>. denote constancy of the preceding parameter over time.
