Your question: What causes large scale patterns of biodiversity?

Biodiversity patterns emerge as a combined result of speciation, extinction and migration, and play an important role in the stability of ecosystems and global climate (Symstad et al., 2003).

What is the biggest cause of biodiversity?

Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.

What causes increase in biodiversity?

Biodiversity change is caused by a range of drivers. A driver is any natural or human-induced factor that directly or indirectly causes a change in an ecosystem. … Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).

What are 3 causes of biodiversity?

Why is biodiversity important?

  • Changes in land use (e.g. deforestation, intensive mono-culture, urbanisation)
  • Direct exploitation such as hunting and over-fishing.
  • Climate change.
  • Pollution.
  • Invasive alien species.

What are the patterns of biodiversity?

Biodiversity patterns occur within species, communities, habitats, regions, ecosystems, biomes and the entire Earth. The within-species diversity is studied as genetic diversity (cf. Sect. 6.1) and refers to the total number of characteristics in the genetic composition of a species.
