what is biogeography
What is Biogeography?
  • It is the study of the distribution of species,organisms, and ecosystems in geographic space and through geological time. 
history of biogeography
History of Biogeography

Alfred Russel Wallace

  • Popularly studied Biogeography
  • was a naturalist, explorer, geographer, anthropologist, and biologist. 
  • Wallace is often called the "Father of Biogeography."
types of biogeography
Types of Biogeography
  • Historical biogeography
  • Ecological biogeography
  • Conservation biogeography

Types of Biogeography

Historical Biogeography

  • is called paleobiogeography and studies the past distributions of species. 
  • It looks at their evolutionary history and things like past climate change to determine why a certain species may have developed in a particular area.

Ecological Biogeography

  •  looks at the current factors responsible for the distribution of plants and animals.
  • The most common fields of research within ecological biogeography are climatic equability, primary productivity, and habitat heterogeneity.

Ecological Biogeography

Climatic equability

  • looks at the variation between daily and annual temperatures. 

Primary productivity

  • looks at the evapotranspiration rates of plants.

Habitat heterogeneity

  • leads to the presence of more biodiversity (a greater number of species present).

Conservation Biogeography

  • This is the protection and/or restoration of nature and its flora and fauna.
fundamental concepts of biogeography
Fundamental Concepts of Biogeography
  • Evolution
  • Extinction
  • Dispersal
  • Range and distribution
  • Endemism

Evolution

  • is the change in the inherited characteristics  of biological populations over successive  generations.
  • change in genetic composition of a population

Extinction

  • In biology and ecology, it is the end of an organism or of a group of organisms (taxon), normally a species. 
  • disappearance of a species

Dispersal

  • refers to species movement away from an existing population or away from the parent organism.
  • movement of populations away from their point of origin, related to migration.

Endemism

  •  is the ecological state of being unique to a defined geographic location, such as an island, nation or other defined zone, or habitat type.

Range and distribution

  • is the geographical area within which that species can be found.
