Home ranges calculated for different sub-samples of the dataset, as given by MCP and fixed kernel methods (overall ranging at 95% UD and core area at 50% UD)
The kernel method produced a mean 95% UD area of 437.2 km
2 and a 50% UD core area of 86.4 km 2
(Table 3 ).
Estimated overall ranging areas and 50% core areas were generally
larger for sub-adults (Table 3 ), though differences were not
statistically significant (MCP: U = 80.0,
P = 0.379, n = 30; 95% UD:
U = 88.0, P = 0.598,
n = 30; 50% UD: U = 90.0,
P = 0.659, n = 30).
Range sizes obtained for the few dolphins for which sex was known
did not reveal any obvious differences, although small sample sizes
prevented any statistical analysis (Table 3 ). .
Non-resident dolphins in the main area had larger home ranges than
resident individuals, although sample sizes were small and
differences were not significant (Table 3 ).
