Final answer:
The example of all offspring born being female in an isolated population of Florida panthers is a case of demographic stochasticity, which is random variation in demographic parameters like the sex ratio of offspring.
Step-by-step explanation:
In the scenario where an isolated population of ten Florida panthers produces only female offspring in a given year, we are dealing with an example of demographic stochasticity. This type of stochasticity refers to random variation in demographic parameters such as birth rates, death rates, and the sex ratio of offspring. It is a consequence of the random nature of birth and death events that occur in a population. In contrast, environmental stochasticity pertains to fluctuations in the environment, such as variation in rainfall, temperature, and food sources, that can affect birth and death rates in populations. Since the given example focuses on the sex ratio of the offspring rather than environmental fluctuations, it is classified as demographic stochasticity.
