AMPHIBIAWEB
Rana dunni

Subgenus: Pantherana
family: Ranidae
Taxonomic Notes: This species was placed in the genus Lithobates by Frost et al. (2006). However, Yuan et al. (2016, Systematic Biology, doi: 10.1093/sysbio/syw055) showed that this action created problems of paraphyly in other genera. Yuan et al. (2016) recognized subgenera within Rana for the major traditional species groups, with Lithobates used as the subgenus for the Rana palmipes group. AmphibiaWeb recommends the optional use of these subgenera to refer to these major species groups, with names written as Rana (Aquarana) catesbeiana, for example.

From the IUCN Red List Species Account:

 

Range Description

This species is known from Lake Pátzcuaro, Lake Cuitzeo and the surrounding streams in Río de Morelia, central Michoacán, Mexico.

Habitat and Ecology

It is an aquatic species that lives in deep water with abundant nutrients; eggs are laid in the streams.

Population

It used to be common but over harvesting has greatly reduced the population.

Population Trend

decreasing

Major Threats

This species is locally exploited for human consumption, particularly around the Lake Pátzcuaro area where it is considered a delicious dish. However, no data are available regarding the number of individuals in the local trade.

Conservation Actions

It is not known from any protected areas. The effect of the local trade on the population status of the species in the Lake Pátzcuaro area needs to be evaluated, and there is a need to manage the offtake of this species for human consumption in a sustainable manner. This species is protected by Mexican law under the "Special Protection" category (Pr).

Red List Status

Endangered (EN)

Rationale

Listed as Endangered because of an observed population decline, estimated to be more than 50% over the last ten years, due to over-harvesting and other threats; and because its Extent of Occurrence is less than 5,000km2, its Area of Occupancy is less than 500km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its habitat, and in the number of mature individuals, in central Michoacán, Mexico.

Taxonomic Notes

This species is a member of the Lithobates pipiens complex.
