Flashcards in 446 Aquatic Ecology Deck (279)
why does NPGO affect survival
directly impacts ∂13C
what does PDO affect?
leads to ∂15N (trophic level), not connected to survival
effects of changing SST
shift species distribution, bring new species, new copepods, effect salmon species?
climate change effects
intensify winds, stronger upwelling - may increase productivity, change migration patterns, affect precipitation patterns
effects of changes in precipitation
warm dry summers lethal to salmon stock
truck fish from lake to river/ocean?
CO2 + H2O -- HCO3 + H
affect critical life stages
killing VI shellfish stocks
Chinooks that return to the fresh water one or two years earlier than their counterpart
most consisten eutrophication effects
shifts in algal species composition
increased frequency/intensity of nuisance blooms
