Study Notes
Animal Distribution
- Animal distribution is the arrangement of animals on the Earth's surface, including land and water.
- This can be categorized into two types: geographical (horizontal) and bathymetric (vertical).
- Geographical/Horizontal Distribution: Describes the distribution of animals across continents and islands.
- Bathymetric/Vertical Distribution: The distribution of animals in relation to the vertical surface of land and water. This can be divided into horizontal and vertical aspects further.
-
Bathymetric/Vertical aspects can be studied based on depth
- Limnobiotic distribution: Deals with animals in fresh water sources
- Holobiotic distribution: Distribution in oceans (all types of water bodies)
Animal Distribution in Time
- Describes the distribution of animals across Earth's history, using fossil evidence.
- This type of distribution is studied using a geological time scale.
-
Patterns of distribution are generally broken down into these categories
-
Arctic Distribution: animals restricted to polar ice caps, characterized by bipolarity
- Shows a characteristic pattern where animals live in both the Arctic and Antarctic regions
- Examples include specific genera of invertebrates, mollusks, arthropods, etc.
-
Tropical Distribution: animals found in regions between the tropics
- This zone is known for maximum biodiversity, many species thrive here.
- Continuous Distribution: a widespread, consistent distribution over large areas
-
Discontinuous Distribution: species or groups of species existing in geographically isolated places, not everywhere
- Examples include specific species of animals, and illustrated in tables with present distribution, origins, etc.
-
Arctic Distribution: animals restricted to polar ice caps, characterized by bipolarity
Modes of Animal Distribution
- Theories explain how animals might have spread throughout the Earth.
- Sweeps take bridges: Animals travel to new areas through accidental dispersal (floating ice, logs).
- Filter bridges: Temporary land connections that let some organisms migrate but not others
-
Corridor bridges: Permanent land connections that enable species movement
- The example provided shows the faunal evolution of the camelids across continents
