Fig. 1. Conceptual framework showing the different states of adult Mountain Plovers (Charadrius montanus) during brood-rearing on three habitats. The figure only shows movement to a different state. Staying in the same state is not shown. Dashed lines represent mortality events and solid lines represent movement of an individual to a different habitat. A live state is represented by “l” and dead state by “d”. Agricultural fields are represented by “AG” with red arrows denoting movement off this habitat, “PD” represents grassland occupied by prairie dogs with blue arrows denoting movement off this habitat, and “GR” represents grassland not occupied by prairie dogs with green arrows denoting movement off this habitat.
