Figure 1
(a) Location of Columbia spotted frog breeding ponds in (i) Keeler and (ii) Marten Creeks, Montana, sampled for capture-recapture and genetic analyses. (b) Movement distributions of (i) juvenile and (ii) adult Columbia spotted frogs from Keeler and Marten Creeks, Montana. Negative values represent downstream movements and positive values upstream movements.

Figure 2
Movements of juvenile Columbia spotted frogs from low elevation ponds to a high elevation lake in Keeler Creek, Montana. The inset shows a juvenile Columbia spotted frog (approximately 25mm in total length). Vector A represents an elevation gain of 770m over a horizontal distance of 4240m (18° mean incline); vector B an elevation gain of 760m over 4620m (16° incline); and vector C an elevation gain of 700m over 1930m (36° incline). The numbers of frogs observed moving from each low elevation pond to the high elevation lake are shown in parentheses.
