Question

the designation criteria for the international union for conservation of nature (iucn) red list of threatened species include which of the following factors?
□ genetic diversity
□ observed percentage decline in populations
□ habitat pollution levels
□ population size
□ extent of current range

Explanation:

The IUCN Red - List designation criteria consider factors related to the species' population status (such as observed percentage decline in populations, population size), its distribution (extent of current range), and genetic factors (genetic diversity). Habitat pollution levels are not direct criteria but can influence the other factors.

Answer:

genetic diversity
observed percentage decline in populations
population size
extent of current range
