ØÒCold-waterÓ species, peak in spring
and early summer
ØHigher development rate in lower
temperature
ØLower EPR compare to Ctyp, Cfin,
similar to Cham
ØLower egg mortality (egg
carrier)
ØHigh concentration in shallow area
(food limitation?)
ØMaintain population size on the
Bank, supply from upstream
(match Davis 1984)
ØDecrease of abundance after summer:
1.high mortality rate in the model
(T-dependent, increase
of predator in summer, Q10, visual predator)
2.other possible reason: less food
(tested, false), less EPR in
warmer water (no exp support)
