Population Ecology
- What is it?
- Sub Field of ecology that
deals with the dynamics
of species population
- The way a population
interacts with the enviroment
- Change in the size of a
population throught time
and space
- Sub Field of ecology that
deals with the dynamics
of species population
- Species
- Basic unit of taxonomic classification consisting
of a population or series of populations that are
closely related
- Basic unit of taxonomic classification consisting
of a population or series of populations that are
closely related
- Population
- Group of individuals of the same
species living in the same place
- Group of individuals of the same
species living in the same place
- 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.
- Ecology
- Individual characteristics:
Age, Stage, Size, Sex,
Behavior
- Individual Processes:
Development, Growth, Feeding,
Reproduction, Death

- Ecology
- Geographical Range
- Potential distribution of species
and populations
- Cosmopolitan
- Species ditributed worldwide
- Ex: Cannis Lupus ( Grey wolf)
- Ex: Cannis Lupus ( Grey wolf)
- Species ditributed worldwide
- Endemic
- species found only in small places,
distributed in a resticted and unique
area only in that area
- Ex: lemur catta ( Madagascar lemur)
- Ex: lemur catta ( Madagascar lemur)
- species found only in small places,
distributed in a resticted and unique
area only in that area
- Cosmopolitan
- Variables of Geographic Range
- History
- 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.

- Bological tolerances
- An individual of a certain species can´t
withstand al types of ecosystems. Ex: Ursus
maritimus can´t survive in a rainforest
ecosystem.

- Other species
- Interactions among different species
- Interactions among different species
- Combination of the
factors
- History
- Potential distribution of species
and populations
