+===== Introduction =====
-Intraguild predation is a very widespread and important interaction in many systems. It happens when two or more species that make use of similar resources, making them competitors, also also have predator-prey interactions. In the Coachella Valley, California, four scorpion species engage in intraguild predation among themselves. Polis & McCormick (1987) carried out a study on these four scorpion species, and concluded that the most abudant scorpion limited the growth of the others, not through competition, but rather because predation.

It happens when two or more species that make use of similar resources (that is, a guild), making them competitors, also prey on each other. In the Coachella Valley, California intraguild predation occurs among four scorpion species. Polis & McCormick (1987) carried out a study on these species, and concluded that the most abudant scorpion species limited the growth of the others not through competition, but rather because of predation.
+In this system, predation seems to be linked to a lack of other resources for the predator, mobility of the prey, and to disparate sizes (and often ages) of predator and prey. It is postulated that the intraguild predator may have a large impact on the characteristics of the other species.

 ===== Suggested questions =====
-  *Can the predator-prey interaction, rather than competition, be the decisive factor for which species is most abundant?
+  *When is the predator-prey interaction, rather than competition, the decisive factor for which species is most abundant?
-  *How does the relevance of the age structure to the intraguild predation interaction affect the system? What about symmetry?
+  *Incorporate into your model and analyze the impact of one of the species traits over the persistence of different species. For instance, what is the relevance of age structure to the intraguild predation interaction affect the system? What about symmetry? Can this analysis offer further insight into the authors' hypotheses?
