Lab Report for Population Dynamics Lab Population Dynamics Lab Report As you complete each slide of the Population Dynamics Virtual Lab Activity, please fill in this lab report with the appropriate information and data. Purpose: Analyze graphs to figure out the population size of two marine species. Explain how predation, birth, and death rates impact marine populations. Describe how biotic and abiotic factors influence marine populations. Research: Prey initial size: the starting number of prey. Prey growth rate: the birth rate of the prey. The bigger the growth rate, the quicker the prey population will increase. Predator initial size: starting number of predators. Predator death rate: the death rate of the predators. A bigger death rate means predators will die out faster. Capture efficiency: This number represents the ability of the predator to capture the prey over some time interval. A larger value for this parameter means that the predators have a better chance of capturing prey. Hypotheses: Prediction 1: If the starting population of the prey is higher than the predators, the resulting population of the seals will be higher than the population of the whales.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
