HELP ON ECOLOGY LAB REPORT PLEASE!!!
- The AIM of this lab exercise: Does Eastern Mosquitofish (Gambusia holbrooki) population structure differ with season?
- You will compare population structure in an FIU pond from February 2018 (previous semester) with the data that you collect this semester (September 2018).
- CREATE HYPOTHESIS ABOUT POPULATION STRUCTURE (HELP PLEASE)
(HELP PLEASE) Include at least one paragraph ON THE key points of comparison between the life tables. Include the major results for population structure, even if no difference is found! Do these populations differ with respect to optimal age of sexual maturity, R0, G, and r?
