Appendix F (FIG. F1). The relationship between estimated pond and season-specific newt densities and transition probabilities between migratory states for male and female Notophthalmus viridescens. A) Estimated probability of transitioning from a migrant (M) to a resident (R), (i.e., probability an individual over winters in the pond after migrating the previous year) and B) estimated probability of transitioning from a resident to a migrant, (i.e., probability of migrating to overwinter in the forest after being a resident the previous year). Closed symbols = Sylvatica Pond and open symbols = Horton Pond. Estimates based on the top model (Table 1, Appendix C Table C2).
