Figure 1.
Escapement monitoring sites for sockeye salmon.
Escapement monitoring sites for sockeye salmon throughout their natural range in the North Pacific. These sites (N = 279) yielded escapement records spanning at least three generations, or 12 years. Numbers displayed on map correspond to identification numbers for monitoring sites in Tables S1 and S2.
Figure 2.
Genetic differentiation among spawning sites of sockeye salmon.
Spawning ground sites sampled for two separate microsatellite DNA baselines for sockeye salmon. The presence of significant barriers to gene flow between sites are displayed by red lines (line width scaled to genetic differerentiation). See text for further explanation.
Figure 3.
Range-wide map of assessed sockeye salmon and their IUCN status.
Numbers displayed on map correspond to identification numbers for sockeye populations listed in Tables S1, S2 and S3.
Figure 4.
Southeastern range map of assessed sockeye salmon and their IUCN status.
Numbers displayed on map correspond to identification numbers for sockeye populations listed in Tables S1, S2 and S3.
Figure 5.
Retrospective analysis to examine effect of temporal trends in populations.
Frequency of different threat categories applied using Red List A2 criterion across a series of hypothetical years (1962–2004). CR = Critically Endangered, EN = Endangered, VU = Vulnerable. See text for additional details.
