How does biogeography affect biodiversity?

How does biogeography affect biodiversity?

Biodiversity within a given ecosystem will be affected by a number of biogeographic factors: Larger habitats tend to promote biodiversity better than smaller habitats (more available niches = less competition) Ecology at the edges of ecosystems is different from central areas (e.g. more sunlight, more wind, etc.)

What is a biogeographic factor?

Biogeography is the study of the geographic distribution of living things and the abiotic (non-living) factors that affect their distribution. Abiotic factors can include temperature, moisture, nutrients, oxygen, and energy availability, as well as disturbances from events such as wind and fire.

What are the two key biogeographic factors that affect the species diversity of biological communities?

Temperature and geography play very important roles in determining the location in which a particular plant or animal will migrate to.

What is biogeographic diversity?

Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area.

Why is it important to know the biogeographic regions of the world?

Biogeographic regions are geographical areas that are defined based on the species found in them, which provides invaluable information to ecologists and natural resources managers for understanding large scale processes that affect species and ecosystems.

What are the 4 factors that affect biodiversity?

Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).

What 3 factors affect the biodiversity of an ecosystem?

Factors that affect biodiversity in an ecosystem include area, climate, and diversity of niches.

What are biogeographic challenges?

Usually, biogeography is subdivided into historical, ecological, and regional biogeography. More recently, environmental problems led to a great variety of topics—e.g., forest dieback, air and water pollution, desertification, degradation of rainforests—which are treated in applied biogeography.

What are the characteristics of a biogeographic region?

biogeographic region, area of animal and plant distribution having similar or shared characteristics throughout. It is a matter of general experience that the plants and animals of the land and inland waters differ to a greater or lesser degree from one part of the world to another.

What are the biogeographic regions of the world?

Based on the original proposal of Philip Sclater and Alfred Wallace, the Earth’s land surface is divided into six biogeographic regions: Nearctic region, Palaearctic region, Neotropical region, Ethiopian region, Oriental region, and Australian region.
