DESCRIPTION:'Revisiting the link-species scaling relationship in ecological
  networks'\n\nTimothée Poisot\, University of Montreal\n	Tuesday February 2
 5\, 12-1pm\n	Montreal Neurological Institute\, deGrandpre Communications Ce
 ntre\n\nAbstract: Community ecologists are fascinated by counting things. 
 It is therefore no surprise that the early food web literature paid so muc
 h attention to counting species\, counting trophic interactions\, and comp
 uting the relationship between these numbers. More species always means mo
 re interactions\; this scaling between species richness and number of inte
 ractions is universal. In fact\, this scaling underlie most means of descr
 ibing a food web. Accurately predicting both is essential when trying to m
 odel food web structure. The number of links in a food web does not simply
  scale with the number of species: it also must obey constraints fixed by 
 biology. These constraints determine both the maximum and minimum number o
 f links\, but have not been used in previous attempts to model the relatio
 nship between links and richness. Using probabilistic programing\, we show
  how the relationship between interactions and richness boils down to a si
 ngle parameter\, which can in turn be used in generative models of ecologi
 cal networks.\n
