In the example of the two species of Lobelia given in the textbook, one species showed semelparity and the other showed iteroparity.A difference in which factor was most responsible for this difference in life history strategy?

Habitat plays a critical role in determining the probability of survival for a species. The environment in which a species lives can affect factors such as competition for resources, availability of food, and vulnerability to predation. In the case of the two species of Lobelia, the semelparous species was found in a harsher environment, where survival was less certain. This led to a strategy of maximizing reproductive effort in the first year of life, rather than risking the chance of not surviving to reproduce again. The iteroparous species, on the other hand, lived in a more stable and predictable environment, allowing for a strategy of multiple reproductive events over the course of its lifetime.
