Syrphids as Natural Enemies of Cereal Aphids in Germany: Aspects of their Biology and Efficacy in Different Years and Regions. Agriculture, Ecosystems and Environment 39− RATE = Energy gained in foraing/(time searching + time handling) put into symbols, this equation reads: R = Ef/(Ts + Th) from which the more complex disk equation emerges (see Stephens and Krebs () for the algebra): R = (le - s)/(1 + lh) where: s = cost of search per unit time l = rate of encounter with items h = handling time e = energy gained per encounter In theory, a forager finds the behavior that . This relationship was first summarized mathematically by C. S. Holling in as y = T t ax/(1 - abx) where y is the number of discs removed, x is the disc density, T t is the total experimental time, a is a constant describing the probability of finding a disc at a given .

The Holling type III equation is described by f(x)=ax2n2+x2,f(x)=ax2n2+x2, where xx is the amount of prey available and a0a0 is the maximum consumption rate of the predator. Graph the Holling type III equation given a=a= and n=5.n=5. What are the differences between the Holling type II and III equations?. Functional Responses, Holling’s Disk Equation, and Predation Modeling Outline. Predators may respond to changes in prey-abundance in several ways: · by changing individual behaviour in the short-term (functional response) · by learning, up to the scale of a predator-lifetime (developmental response). In Problem 1 (see Fig. 1), the student's first equation represents the total problem to combine the number of Tommy's red checkers with the number of Tommy's black checkers to find the total.
