Models estimate the probability a population persists given demographic and environmental risks.
PVA uses demographic data, simulations and stochastic events to estimate extinction risk over time (for instance 95 percent persistence for 100 years). Software: VORTEX, RAMAS.
PVA outputs probabilities, not certainties. Inputs include survival, fecundity and catastrophes. Sensitivity analysis shows key parameters.
Example: PVA suggested translocations for the Florida panther.
Models estimate the probability a population persists given demographic and environmental risks.
Population Viability Analysis is one of the 52 topics in Taxonomy & Biodiversity. It is rated Advanced, so it suits learners who want specialist depth. Related topics in this area include Conservation Biology, IUCN Red List Criteria, Conservation Genomics.
PVA guided management of Florida panther.
Work through the Beginner topics in Taxonomy & Biodiversity first, such as Taxonomy, Binomial Nomenclature, Taxonomic Hierarchy, then return to Population Viability Analysis. Advanced topics assume the Intermediate vocabulary.
The closest topics to Population Viability Analysis are Conservation Biology, IUCN Red List Criteria, Conservation Genomics, Minimum Viable Population. Comparing them side by side is a good way to see how the ideas connect.
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Population Viability Analysis. To practise the whole of Taxonomy & Biodiversity, use the Taxonomy & Biodiversity quiz.
Population Viability Analysis: Models estimate the probability a population persists given demographic and environmental risks. Conservation Biology: The scientific study and protection of biodiversity. Read both side by side and note what each one explains.
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Conservation Biology and explain the difference aloud. Finally, take the Taxonomy & Biodiversity quiz and come back to this page for any question you miss.
