+ | ===== Introduction ===== | ||
+ | Under a bridge in north central Florida lives a population of mud dauber wasps. | ||
+ | These wasps are voracious predators with an extremely interesting hunting mode: female wasps are specialized in capturing and paralyzing spider preys only to store them in mud nests as a way to keep them safe (and zombie-like alive) to be devoured later by the wasp larvae. However not all mother wasps have the same preferences for which type of spider they like to offer their offspring, a pattern known as individual specialisation. In the same population there are specialist wasps, that hunt only species from a single genus; and generalist wasps, that hunt spiders from as much as 7 genera. | ||

+ | Specialist individuals might be more efficient in capturing and handling prey; nevertheless, | ||

+ | ===== Assignment ===== | ||
+ | Propose a model to explore hunting strategies in mud dauber wasps and the effect of competition on coexistence of strategies. | ||
+ | |||
+ | |||
+ | ===== Suggested questions ===== | ||
+ | - Explore how the degree of intraspecific competition influences the prevalence (and coexistence) of specialist and generalist hunting modes. | ||
+ | - How does resource availability influences coexistence of strategies, or exclusion of one by the other? | ||
+ | - Does competition between spider species influences diversity of predator strategies? | ||
+ | - Would both strategies (specialist and generalist) be equally good for the offspring? Explore scenarios where larvae fed by mothers choosing different strategies obtain different levels of advantage. | ||
+ | |||
+ | Further well-grounded questions from the group are welcome. | ||
