An increase in rainfall brings more plant resources to a population of lizards, but it also brings more predators. These changes result in both an increase in fecundity and a decrease in survivorship. Under these conditions, which event is most likely?

The per capita birth rate of the population will increase.

Explanation:

Fecundity refers to the ability of an organism in order to produce more number of offsprings. This leads to the increase in the number of population of lizards which is facilitated due to the increasing rainfall. In addition to this, the high abundance of rainfall also allows the number of predators to increase as a result of which it becomes difficult for them to survive.

From the above condition, it can be generalized that the population of lizard will increase at a much higher rate.
