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 genetic diversity as it affects a species' long - term survival potential. Observed percentage decline in populations indicates the rate at which a species is decreasing. Population size is a fundamental measure of a species' viability. The extent of current range shows how widely a species is distributed, which is important for its survival. Habitat pollution levels are not direct criteria, though they can influence other factors like population size and range.

Answer:

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