Sometimes, we observe that animals exhibit correlated behaviors, either along the same behavior axis but in different contexts, or across different behavioral axes.  In class, we discussed a study of salamander larvae that looked at patterns of individual activity during periods of high predator activity (day) and low predator activity (night).  What was the primary conclusion of that study (i.e. the major result)?  Does this result support the idea that behavioral correlations are adaptive or that they are evolutionary constraints?  (2 sentences)

In a species of beetle that has been tested for optimal foraging theory (OFT), it was found that female (but not male) beetles deviated from the prey choice model, preferentially ingesting a mix of higher calorie, high fat foods AND lower calorie, high protein foods. Based on what we learned in class about how constraints may impact foraging decisions, provide a potential explanation for why these female beetles may be deviating from the OFT prey choice model (1-2 sentences).

Group living can improve access to resources through multiple mechanisms. Choose two of the following mechanisms and explain how each operates to produce greater resource access benefits for those living in social groups. In each answer, identify if this is passive attraction via cues or active information transfer via signals.
