Another tool used by population ecologists is a survivorship curve, which is a graph of the number of individuals surviving at each age interval versus time. Within a particular habitat, a population can be characterized by its population size (N), the total number of individuals, and its population density, the number of individuals within a specific area or volume. To investigate this you can do a computer experiment by altering reproduction at different ages. Another tool used by population ecologists is a survivorship curve, which is a graph of the number of individuals surviving at each age interval plotted versus time (usually with data compiled from a life table). They differences in offspring number and size and degree of parental care result in different survival patterns throughout the developmental stages of individuals. Some animals from the first catch may learn to avoid capture in the second round, thus inflating population estimates.

Life tables provide important information about the life history of an organism. In type III survivorship curves, early ages experience the highest mortality with much lower mortality rates for organisms that make it to advanced years. Thus, the distribution of the individuals within a population provides more information about how they interact with each other than does a simple density measurement. Organisms in the middle of the continuum are neither quite large nor small, have middling life spans and rates of growth, produce moderate numbers offspring in which they invest a moderate amount of resources and parental care. survivorship curves survivorship curves are used to compare the pattern of DismissTry Ask an Expert Ask an Expert Sign inRegister Sign inRegister Home I have to curve that depict the individual whose chance for the survival chance for the survival is independent on is is independent Is independent on The CDC released the following data in its 2013 Vital Statistics report.
