Question

Burmese pythons (Python molurus bivittatus) are constricting snakes that can reach enormous sizes (up to 7 meters in length). They are native to Southeast Asia but were released into southern Florida from the pet trade. Many other snakes occur naturally in this area. Are the introduced pythons a problem?

A life table would help researchers make predictions about python population growth. If you were to track a cohort of pythons over time to construct a detailed life table, what kind of data would you want to collect?

Accepted Answer

Hello everyone and welcome to today's video. So which of the following data is required to create a detailed life table for a species cohort? I want you to recall from previous videos what the requirements or what the life table for a species cohort is trying to do and in case you forgot, I want to help you recall this. Well the species life table for its cohort is going to follow the survival and the reproduction of all members of the cohort from birth to death. So remember that the survival and the reproduction are going to be the main things that we're looking at when we're creating this life table. Now that we know this. Let's jump our answer choices so that we can begin solving the problem. So answer choice A. Is going to be a specific survivorship, survivorship can be said that it is the same as a survival rate. So this is definitely going to be needed. And we're not going to cancel it out. These answer choice B. A specific quantity in case you don't know what this means. The quantity is an organism's ability to reproduce. Which as we can see, is also something that we need in order to create this detailed life table. So we're not going to cancel this out either. And these two answer choices do not provide really any information that we need. So answer choice is A. And B. Or answer choice C. Are you going to be the final answer to our question? That is the end of the video. And I really hope this helped you
