What is it about?

Mountain ranges in North America have slowed down plant migration after major climatic changes such as glaciation. Mountains, however, do not form a continuous barrier and plants may cross ranges at the lower points. This article concerns moss species in central Mexico that may have crossed the Neovolcanic Belt from the north, if temperate, or from the south, if tropical in origin.

Why is it important?

Mosses as well as other plants are not distributed at random. Current moss distribution in central Mexico may show how climate and other events have affected the ranges of organisms.

Perspectives

This article is one of several on floristic corridors across a montain range in Mexico. Because it is one that runs from coast to coast, the Neovolcanic Belt has regulated the dispersal of organisms, and mosses seem to confirm it.
