¥Top figure is based on climatology from NH20, Newport Line,
OR; Bottom figure based on SCB
climatology
¥In the south, copepods spawned as early as day 50 can enter
dormancy, whereas in the north, itÕs
40 days later.
¥Peak dormancy entrance date is between days 125-175 in the
S, and between days 175-225 in
N.
¥Predation during the ÒGreenÓ period would remove potentially
successful copepods
¥Suboptimal cold temperatures(and low food) in the N during the
early part of the year limit success
then, whereas overly warm temperatures
later in the year limit success in S
during that time (recall the optimal window)
