IUCN Red List of Threatened Species

Geographic distance did not explain patterns of genetic variation in Andean populations. Family Cricetidae New World rats and mice, voles, hamsters, and relatives.

The soft grass mouse, Akodon mollis, was chosen as the test organism because of its wide elevational and latitudinal range.

Superclass Gnathostomata jawed vertebrates. More extensive sampling, including more elevational belts and mountain replicates, additional molecular markers, and the inclusion of isolation by resistance methods, might help to shed further light on speciation by Andean mammals. While ADW staff and contributors provide references to books and websites that we believe are reputable, we cannot necessarily endorse the contents of references beyond our control. Bilateria bilaterally symmetrical animals.


Genus Akodon grass mice and South American field mice.

Soft grass mouse

Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Phylogenetic analyses of the mitochondrial Akodin b gene showed spatial structuring of A. Sigmodontinae in the Andes of Peru. Classification Kingdom Animalia animals Animalia: The mechanisms responsible for the species composition of montane biotas remain poorly understood.

Infraclass Eutheria placental mammals. The ADW Team gratefully acknowledges their support.

Some features of this site may not work without it. Subclass Theria Therian mammals. Superfamily Muroidea mice, rats, gerbils, and relatives. The Animal Diversity Web is an educational resource written largely by and for college students. This dissertation reviews the possible role of these mechanisms in the speciation of mammals in Andean habitats. Confused by a class within a class or an order within an order?

Species Akodon mollis soft grass mouse. ADW doesn’t cover all species in the world, nor does it include all the latest scientific information about organisms we describe. Suborder Myomorpha mice, rats, gerbils, jerboas, and relatives. Moolis Sigmodontinae South American rats and mice. Additional Information Encyclopedia of Life.

Akodon mollis

Class Sarcopterygii lobe-finned fishes and terrestrial vertebrates. Deeper lineages at the southern limit of the species coincide with the oldest part of the Andes, while shallower clades were found in the more recent northern Andes.

Partial least squares and multivariate multiple regression analyses showed a significant association between skull shape and environment. The most important variables were associated with temperature, and these almost perfectly correlated with elevation. The Animal Diversity Web online. An unambiguous test of the Ecological Gradient hypothesis was not possible; however, Montane Vicariance was suggested in two instances where mice at similar elevations on moolis mountains were closely related.

About Deep Blue Data. To cite this page: Parapatric and allopatric speciation, in the forms of the Ecological Gradients and Montane Vicariance hypotheses respectively, have been suggested to explain the diversification of Andean fauna.
