1
Q

exploitation

A

interaction between populations that enhances fitness of one individual while reducing fitness of the exploited individual

2
Q

parasitoid

A

an insect larva that consumes the host

3
Q

population level effect of exploitation

A

reduce dN/dt of one species and raise dN/dt of the other

4
Q

population growth model

A
dN/dt = rN
dN is change in # of individuals
dt is change in time
r is rate of growth
N is number of individuals in the population
5
Q

population growth model adding parasites/predators

A

dN(h)/dt = r(h)N(h) - pN(h)N(p)
p is rate of parasitism or predation
N(h) is number of hosts
N(p) is number of predators/parasites

6
Q

parasite/predator growth model

A

dN(p)/dt = cpN(h)N(p) - d(p)N(p)
cpN(h)N(p) is conversion rate of hosts into predator offspring
d(p)N(p) is predator death rate
