Schematic of the recruitment compensation documented by Cayuela et al. (2) depicting how increasing the levels of human environmental modification (x axis) affects key demographic rates of survival, recruitment, and overall population growth (y axis). Populations are stable when growth rate is equal to one, increase when growth rate is above one, and decrease when it is below one. As yellow-bellied toad populations transition from natural habitats to areas formerly used by humans to areas actively used by humans, survival decreases. Yet elevated recruitment of young toads compensates, yielding stable populations. However, with still further anthropogenic pressure beyond those quantified by Cayuela et al. (2), populations may eventually be unable to produce enough young to compensate for the heightened mortality they experience, leading to a threshold effect and population collapse.
