Population Ecology
  1. What is it?
    1. Sub Field of ecology that deals with the dynamics of species population
      1. The way a population interacts with the enviroment
        1. Change in the size of a population throught time and space
        2. Species
          1. Basic unit of taxonomic classification consisting of a population or series of populations that are closely related
          2. Population
            1. Group of individuals of the same species living in the same place
            2. Population ecology is "the plural of Ecology" it studies the same dynamics that ecology but in groupsof individuals (populations). Population ecology´s concepts came from the basis of ecology.
              1. Ecology
                1. Individual characteristics: Age, Stage, Size, Sex, Behavior
                  1. Individual Processes: Development, Growth, Feeding, Reproduction, Death

                  2. Population Ecology
                    1. Population Characteristics: Population Density, Age Distribution, Sex ratio, Spatial distribution
                      1. Population Processes: Population Growth, Changes in age Distribution, Mortality
                  3. Geographical Range
                    1. Potential distribution of species and populations
                      1. Cosmopolitan
                        1. Species ditributed worldwide
                          1. Ex: Cannis Lupus ( Grey wolf)
                        2. Endemic
                          1. species found only in small places, distributed in a resticted and unique area only in that area
                            1. Ex: lemur catta ( Madagascar lemur)
                        3. Variables of Geographic Range
                          1. History
                            1. Distribution of species in past times. Ex: long time ago, species were distributed in pangea. When pangea divided the classification in the distribution of species divided acording to the parts of pangea, The gondwanan distribution and the laurrasian distribution.
                            2. Bological tolerances
                              1. An individual of a certain species can´t withstand al types of ecosystems. Ex: Ursus maritimus can´t survive in a rainforest ecosystem.
                              2. Other species
                                1. Interactions among different species
                                2. Combination of the factors
