In class, we learned about a genus of birds (reed warblers) that vary in mating systems, from monogamous to polygyny and promiscuity. What association did researchers (Leisler et al) find between mating system and habitat quality in the birds they studied? Monogamy was prevalent in poor-quality habitats Polygyny was prevalent in dry habitats Polyandry was prevalent in high-quality habitats Male dominance polygyny was prevalent in medium-quality habitats

In songbirds, social monogamy, rather than genetic monogamy, is the most common mating system, while polygyny is the most common mating system in mammals. What biological difference between songbirds and mammals might account for this difference in the type of mating system and why would social and not genetic monogamy be more common in songbirds? NOTE: there are two separate questions here you must answer in order to get the 2 extra bonus points. No partial points will be given.

Many bird species produce relatively few offspring and have monogamous mating systems. How are these characteristics likely to be related to parental care and courtship behavior? Are these species likely to be r-selected or K-selected? Explain. Males exhibiting resource defense polygyny often defend territories. What is the likely spatial dispersion pattern of these males? What is the likely dispersion pattern of the entire population (assuming that each female has multiple offspring which remain with a parent for an extended period of time after birth)? Are females occupying territories with a high abundance of food resources likely to be more or less selective in their choice of what to eat than females occupying territories with fewer resources? Explain.

1. Identify one example (not discussed in lecture or your readings) of monogamy, polygyny, polyandry, and promiscuity. Describe for each example how their mating system works and why (what specific costs/benefits) that strategy provides each sex. 2. Identify one bizarre example of intrasexual selection not discussed in lecture or your readings. What do you think holds the trait in check from continuing to be exaggerated? 3. Identify one bizarre example of intersexual selection not discussed in lecture or your readings. Is the "choosy" mate making a choice based on good genes, resources, or both? 4. Identify and describe the life history strategy of one species you find interesting. Your species must be one that has not been discussed in the lecture or your readings. Why did you select this species?
