Belt, pp 199-226.
These sites form part of the province of the neovolcanic
belt, which is formed by the subprovince of the plains and mountains of Queretaro and Hidalgo and the subprovince of the Anahuac lakes and volcanoes.
Historical biogeography of lowland species of toads (Bufo) across the Trans-Mexican Neovolcanic
Belt and the Isthmus of Tehuantepec.
Osgoodomys banderanus (Osgood's deermouse) is a nocturnal, solitary, medium-sized cricetid that is endemic to western Mexico, in particular the western portion of the Trans-Mexican Neovolcanic
Belt (Fa and Morales, 1991).
The station is in the Zoquiapan National Park, at the Neovolcanic
Belt of Central Mexico, 3000-3500masl (Franco and Burquez, 1981).
The volcanic and tectonic activity is mostly confined to the neovolcanic
zone that crosses the island from southwest to northeast and is the continuation of the ridge on land (Saemundsson 1979).
Geographically, 70% of this group was found to the east of 100o W latitude and was concentrated at the eastern extreme of the neovolcanic
axis in the states of Puebla, Hidalgo, and Veracruz, and extending down into Oaxaca (Fig.
Both molecular clock calibrations (based on Nei's D) and geological-age estimates of the Mexican Neovolcanic
Axis are consistent with an initial divergence of no more than 10 million years for the Mexican taxa, and many species are apparently much more recently derived (Shaffer 1984a).
This young strip of neovolcanic
seafloor is glassy, and its bumpy lava surface reflects a multitude of points of light from the strobes and incandescent lamps of cameras towed overhead, or the illumination of robots and submersibles such as Jason and Alvin.
The area covered is in a geologic division known as the "Barrancas" subprovince which is a part of the "Sierra Madre Occidental" province extending 1,200 km from the Neovolcanic
axis of central Mexico through the states of Durango, Chihuahua, and Sonora to the U.
is reported from 2 localities of Mexico: Lagunas de Zempoala (State of Mexico), a high elevation area 2824 m absl on the Transversal Neovolcanic
Belt, and on the island of Guadalupe (State of Baja California), 260 km off shore in the Pacific Ocean.
