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.
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).
Mammals and protected areas in the Trans-Mexican Neovolcanic Belt.
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).
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.
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.
The viviparous lizard Sceloporus bicanthalis is a small, diurnal, ground-dwelling phrynosomatid lizard, restricted to the Neovolcanic
Axis in the center of Mexico at 2,100-4,200 m elevation (Smith et al.
2000), runs parallel to this coast from the northern limit of our study area southward to northern Jalisco, where it merges with the Neovolcanic Axis.
Coastal plains are interrupted in Nayarit by the Neovolcanic Axis.
The state of Morelos is situated in south central Mexico between 2 important geographic zones: the Transverse Neovolcanic
Belt and the Rio Balsas Basin.
Various authors doubted the presence of jaguars in the pine-oak forest of the Transverse Neovolcanic Belt (Nowell and Jackson, 1996; Sanderson et al.
Deciduous tropical forest is common in the Balsas River Basin (at elevations of 400-1,400 m), and pine-oak forests characterize the Transverse Neovolcanic Belt at 1,400-2,080 m.
