 ng things. It is therefore no surprise that the early food web literature 
 paid so much attention to counting species\, counting trophic interactions
 \, and computing the relationship between these numbers. More species alwa
 ys means more interactions\; this scaling between species richness and num
 ber of interactions is universal. In fact\, this scaling underlie most mea
 ns of describing a food web. Accurately predicting both is essential when 
 trying to model food web structure. The number of links in a food web does
  not simply scale with the number of species: it also must obey constraint
 s fixed by biology. These constraints determine both the maximum and minim
 um number of links\, but have not been used in previous attempts to model 
 the relationship between links and richness. Using probabilistic programin
 g\, we show how the relationship between interactions and richness boils d
 own to a single parameter\, which can in turn be used in generative models
  of ecological networks.\n
