How does area affect biodiversity?

Area increases diversity because a larger plot is likely to have more habitats, hence niches, to support a greater variety of species. In addition, many species require a large range for adequate prey or seed forage.

What are the two factors that affect species diversity?

The factors related to these patterns of small- scale species richness include (1) geographic factors such as scale of observation, available species pool and dispersal patterns, (2) biotic factors such as competition or predation and (3) abiotic environmental factors such as site resource availability, disturbance and …

How does climate change affect biodiversity?

This very sensitive region is highly affected by climate. Changes in rainfall patterns could also have serious impacts on drylands biodiversity. Climate change could increase the risk of wildfires, which could change the species composition and decrease biodiversity.

How does biodiversity loss affect diversity?

Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.
