Table 1.
Regions in South Australia from which samples of bottlenose and common dolphin carcasses were obtained, with abbreviations, number of samples and genetically identified sex of sampled individuals.
Table 2.
Summary of genetic variability of bottlenose dolphins using carcasses collected in South Australia. Values are based on mtDNA control region sequences and six microsatellite loci.
Table 3.
Summary of genetic variability of common dolphins, inferred from carcasses collected in South Australia. Values are based on mtDNA control region sequences and seven microsatellite loci.
Figure 1.
STRUCTURE results for a) bottlenose dolphin carcasses from Spencer Gulf and western coastal areas, South Australia; and b) combined datasets from bottlenose dolphin carcasses and free-ranging individuals, Spencer Gulf and western coastal areas, South Australia.
Each vertical column represents one individual dolphin, and the separation of the column into two colours represents the estimated probability of belonging to one or the other population. F = free-ranging dolphins, C = carcasses. Specific geographic locations where dolphins were found or biopsied: FI = St Francis Isles, WSA = western South Australian coast, CB = Coffin Bay, PL = Port Lincoln, NSG = North Spencer Gulf, SESG = southeast Spencer Gulf. See Figure 1 for geographic locations.
Figure 2.
Assignment plot of genotype likelihood values of bottlenose dolphins to population A (Spencer Gulf = black squares) and B (western coastal = white diamonds).
Figure 3.
Haplotype network for mtDNA control region sequences of bottlenose dolphin carcasses collected from western coastal areas and Spencer Gulf.
The size of the ovals is proportional to the number of individuals showing the particular haplotype. Haplotype H1 was considered to be ancestor based on coalescence theory. Each line indicates one mutation between haplotypes, and small circles between connecting lines represent missing or hypothetical haplotypes.

Figure 5.
Sampling regions in South Australia from which carcasses of bottlenose dolphins were collected.
Black dots within regions represent localities for carcasses. Samples are grouped into two geographic areas: western coastal (W coastal) and Spencer Gulf (SG).

Sampling regions in South Australia from which carcasses of common dolphins were collected.
Black dots within regions represent localities for carcasses. Samples are grouped into two geographic areas: western coastal (W coastal) and Spencer Gulf (SG).
