2-4 Biodiversity Flashcards
Biodiversity defined:
can be measured in many ways
What is the difference between species diversity, genetic diversity, and ecosystem diversity?
Compare and contrast species richness and species evenness
Endemic diversity
How does species richness (number of species) vary across taxonomic groups?
Why is species richness a useless concept for prokaryotes?
How does biodiversity change over time?
There have been numerous extinction events, including loss of large mammals during the Pleistocene.
How does biodiversity change over latitude?
It is a driver of potential evapotranspiration, environmental energy, productivity
What are other possible drivers of diversity?
area, heterogeneity, climate stability
there is an exceptions to latitude hypothesis (Mediterranean, desert, taxonomic anomalies)
What is the benefit of biodiversity?
Redundancy, resource use efficiency
What have humans caused in recent biodiversity?
Humans have caused the recent biodiversity crisis and consequences of the crisis
What strategies can be used to compact biodiversity?
