Population: Ecology

This picture was taken at the Arnold Arboretum. Here is a large plot of land where many different shrubs and trees grow for display. All of these plants in one area are their own population. A population consists of organisms that can successfully reproduce with enough mates, food, and shelter. The barriers that this population has to prove it lives in its own environment a part from the city where a population of people live, are the streets. Once one leaves the premises of plots of land with trees and goes out into the street, there is a new population - filled with cars. Each population lives in a certain environment that has its own carrying capacity. I don't know if the arboretum is at its peak of trees, under, or just right, but there is a certain amount of trees this environment can sustain until the population has "overflowed". The arboretum also displays a variety of plants that demonstrate that it could be in Hardy Weinberg equilibrium. It is a large population, with random mating, and mutation. But I don't think this population is in equilibrium because there is no genetic drift or gene flow.
