Table 3.
Model outcomes for the surgical interventions examined using the individual-based model describing dog population dynamics in Villa de Tezontepec, Hidalgo Mexico.
For each intervention, the model was run 1000 times with the outcome of interest being the total dog population size after 20 years. Outcomes are aggregated across all model iterations and summarized as mean population size, standard deviation, median population size, range, and relative change compared to the no intervention scenario.
Fig 3.
Impact of mixed age (Panel A) and young age (Panel B) surgical sterilization interventions (both male and female dogs) after 20 years. Each box represents a summary of the model outcome (population size) across 1000 stochastic model replicates. The top and bottom of each box are the 25th and 75th percentiles, and the line inside the box is the median dog population size. The top whiskers are the minimum and maximum values of population size, excluding outliers, which are represented in the figure by solid circles. The dashed line represents the population community capacity (2924 dogs).
Fig 4.
Impact of female only mixed age surgical sterilization (Panel A) and female only young age surgical sterilization (Panel B) interventions after 20 years. Each box represents a summary of the model outcome (population size) across 1000 model replicates. The top and bottom of each box are the 25th and 75th percentiles, and the line inside the box is the median dog population size. The top whiskers are the minimum and maximum values of population size, excluding outliers, which are represented in the figure by solid circles. The dashed line represents the population community capacity (2924 dogs).
