Question

The noble freshwater wrasse typically forages in pairs, allowing these fish a better chance to spot a predator before getting eaten by that predator. After spotting a predator, a wrasse can engage in one of two behavioral strategies – fleeing immediately (F), or alerting its partner (A) and then fleeing. Fish that flee immediately enjoy a survivorship rate of 60% if their partner also flees immediately and a survivorship rate of 75% if their partner pauses to alert them. Fish that pause to alert their partner enjoy a survivorship rate of 90% if their partner also pauses to alert them, and a survivorship rate of 0% if their partner instead flees immediately. What do we know to be true about this system? Use any of the following equations to justify your answer:

Equations:

E1/Th1> E2/Th2

r = b – d

mean EPx= px(EPxx) + py(EPxy)

r*B > C

b = births/(N*t); d = deaths/(N*t)

? lxbx= R0
