A comparison of G-banded chromosomes of four North American beavers, Castor canadensis (two males, two females), and four Eurasian beavers, Castor fiber (two males, two females), revealed that extensive monobrachial centric fusions distinguished the karyotypes of the two species. The complex multivalent formations that would occur in meiosis of a hypothetical hybrid would be expected to produce unbalanced gametes and postmating reproductive isolation. Thus, neither species was derived from the other; rather, they likely were derived from isolated populations in which some of the acrocentrics fused independently to produce monobrachial homology.Key words: beaver, chromosomes, karyotype evolution, monobrachial rearrangements, reproductive isolation.

Popular Books

The recent publication of several books on the history and ecology of beavers ( Castor canadensis and Castor fiber) illustrates a renewed interest in the construction activities of beavers and their impacts on landscapes. Over one hundred years ago, two popular books on these same topics were published, In Beaver World and The Romance of the Beaver. These books, their authors, and their legacies can still inform today’s readers interested in beavers, ecosystem engineering, and zoogeomorphology.
