5/8/24 - Lecture 21: Predator-Prey Interactions Flashcards
1
Q
Lotka-Volterra predator-prey model
A
dN/dt = rN(aNP)
dP/dt = caNP = mP
r: prey intrinsic rate of growth
a: predator attack rate
c: conversion efficiency
m: per capita mortality rate
N: prey density
P: predator density
2
Q
How does increasing prey carrying capacity affect predator and prey equilibrium density?
A
Increasing the prey’s carrying capacity won’t affect prey density, it increases predator equilibrium density.
3
Q
Parasitoid
A
An organism that, during its development, lives in or on the body of a single host individual, eventually killing that individual
