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
