FIG. 1 in Breeding Population Dynamics of Threatened Crawfish Frogs Inform Targets for Habitat Management

FIG. 1. (A) Post-birth, females-only, stage matrix model of Crawfish Frogs that accommodates age and state-specific transition probabilities and the ''temporary emigration'' of individuals that skip breeding or breed at other sites. (B) Projection matrix of the model used to estimate elasticities and sensitivities of vital rates. Parameters in the matrix model: embryonic survival (Se), tadpole survival (St), metamorph and juvenile survival (Sj), adult survival following the first breeding event (Sa1), adult survival following two or more breeding events (Sa2), probability that a one-year-old juvenile matures at age 2 (p), probability that a two-year-old juvenile matures at age 3 (q), the probability that a mature individual emigrates to become a non-breeding individual (c22), probability that a non-breeding individual remains a non-breeding individual (c'), and clutch size multiplied by 0.5 to represent half of all eggs developing into females (C). We assumed that all individuals mature by age 4. Individuals that emigrate to become a nonbreeding individual may either skip reproduction or breed at another site.
