Demographic signatures of functional relationships given initial species segregation.

Abstract

<p><b>A, B.</b> The two species are strongly interdependent. <b>C, D.</b> The two species are weakly interdependent. Producer is represented in red and cross-feeder is represented in blue. By-product is in gray. Simulations were initiated with two segregated microcolonies (1∶1). Boundaries on the sides are permeable to the by-product and non-cyclic. <b>B, D.</b> Time series of species biomass (N). The thick lines represent the mean (n = 9) and shaded areas represent the standard deviation.</p
