FISHERIES OCEANOGRAPHY COORDINATED INVESTIGATIONS (FOCI):
Responses of Ichthyoplankton Biodiversity and Dynamics to Environmental Change
For many clusters most variance was explained by geographical region and
month in which the samples where taken, while the annual variation only
accounted up to 10% (Fig. 4 above). Therefore, consequent analyses focused on
the May ichthyoplankton assemblage and on each of seven geographical strata
within the GOA individually. Response variables (abundance of species
and cluster, diversity, survival index) were then linked to environmental
explanatory variables (Pacific Decadal Oscillation index (PDO), temperature,
freshwater runoff, total flow and wind indices) by canonical correspondence
and canonical correlation analysis. Temperature-related indices seemed
to be most closely linked to the response variables and diversity and survival
indices were more suitable than abundance indices alone. ![]() |
