In this lesson our instructor talks about population. First she discusses the concept of population. Then she talks about mortality, age structure diagram, population growth, logistic population growth, logistic model, and oscillation. After, she lectures on changes to the carrying capacity, growth strategies, human population, and the Lynx and Hare Case Study. Four complete example videos round up this lesson.
A population is
a group of individuals from one species living in a given area.
the number of deaths per a given population or standardized
population size. A survivorship curve represents how the mortality
of the species varies with age.
potential is the maximum rate at which a given population could grow
under ideal conditions. Exponential growth is the type of growth a
population experiences under ideal conditions.
Capacity (K) is the maximum number of individuals that can occupy an
area under given conditions. The logistic model shows growth rate
from the time a population is introduced to an area to the time it
reaches its carrying capacity.
Growth Rate = r N (1 N / K)
species have rapid population growth when obstacles are limited.
They quickly reach carrying capacity. K-selected species tend
to dominate in stable, established environments.
Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
