Origination rate biodiversity

According to the. 'tropics as a cradle' model, species origination is higher in tropical areas and extinction rates do not vary latitudinally.

If the extinction rate is greater than the origination rate then there will be fewer species and thus less biodiversity.

The current rate of global diversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate and expected to still grow in the upcoming years.

The “problem” with richness Region 1 Region 2 Total Richness = 6 Total Richness = 4 . The extinction rate is the rate at which species are becoming extinct. The development of new species and extinction of existing species are natural processes that have always occurred. The issue that is concerning is that our current extinction rate is much higher than the background (ie normal) extinction rate that would be expected. Biodiversity includes not only species we consider rare, threatened, or endangered but also every living thing—from humans to organisms we know little about, such as microbes, fungi, and invertebrates. At the Center for Biodiversity and Conservation, we include humans and human cultural diversity as a part of biodiversity. The report, spearheaded by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), found that nature is being eroded at rates unprecedented in human history.

Best Answer: origination rate = rate at which the number of species increases. extinction rate = rate at which the number of species decreases. If the extinction rate is greater than the origination rate then there will be fewer species and thus less biodiversity. Biodiversity is a core concept in biology and has been the subject of discussion for decades. It is remarkable that so few generalities about biodiversity exist—probably, as ever in biology, laws are elusive because of the contingent nature of the properties and history of each species and larger group.

Decision VI/9 provides The 2010 biodiversity target has not been met at the global level. None of the twenty-one sub-targets accompanying the overall target of significantly reducing the rate of biodiversity loss by 2010 can be said definitively to have been achieved globally, although some have been partially or locally achieved. An unequivocal, precise, and generally accepted definition of biodiversity does not exist. However the need for such a definition that is both scientifically sensible and universally applicable is The 2019 IPBES Global Assessment Report on Biodiversity and Ecosystem Services asserts that industrial farming is a significant factor in collapsing biodiversity. The health of humans is largely dependent on the product of an ecosystem. With biodiversity loss, a huge impact on human health comes as well.
