 ===== Suggested questions =====
-  * The authors show an intriguing example of reciprocal facilitation between very distant animal species. What type of dynamics (in terms of species densities, community composition and coexistence) are expected if the facilitation is not reciprocal? In other words, if the interaction is neutral for one of the species, does it affect populational patterns found in the model in which facilitation is reciprocal? Which species is most affected by the interaction?
+  * Based on your model, what changes would you expect in the dynamics of the system (in terms of species densities, community composition and coexistence) if the facilitation were not reciprocal? In other words, if the interaction is neutral for one of the species, does it affect populational patterns found in the model in which facilitation is reciprocal? From that, can you infer which species is most affected by the interaction?
-  * The authors argue that the interaction is a facultative facilitation. In the absence of cattle, the effects provoked by ants (i.e., enhancement of soil nutrients increasing plant quantity and quality) could feedback negatively in its own species, altering the micro-habit that favors the construction of ant nests. How would you considerate this negative feedback and how does it influence final population densities and stability of the system?
