One person said grounhogs are named Philohela minor and another said its
Marmota monax. I'll repeat my question...Is there more than one animal
called a groundhog or woodchuck?.
One species, Marmota monax.
Scientific names of numerous species - animal, plant, and protists - are
being changed, to a large degree, based on newer DNA homology
comparisons. Guess taxonomists gotta have something to do.
I wasn't aware of the groundhog/woodchuck's previous moniker - have really
only been paying attention to them for the last 10 years or so. Some
biomedical researchers are looking at them as an animal model of human
disease - they have a hepatitis virus that induces hepatic
carcinoma(malignant tumors).
Taxonomic changes in the microbiological field have been rampant over the
past 10-15 years. Several of the commonly-encountered pathogens that I
deal with on a regular basis have experience name changes several times:
Pasteurella haemolytica has become Mannheimia haemolytica
Corynebacterium pyogenes -->Actinomyces pyogenes -->Arcanobacterium pyogenes
Treponema hyodysenteriae-->Serpula hyodysenteriae-->Serpulina
hyodysenteriae-->Brachyspira hyodysenteriae
Name changes in the plant world have been less common(to my knowledge) -
are the plant taxonomists sleeping? Several of the oak species have been
'renamed', most not so much on the basis of DNA comparisons as by
previously accepted misidentifications and acceptance of conventional names
based on chronologic identification(someone had previously IDed and named a
species, but a later name had gained more widespread usage). Only other
major plant name change that I can think of, off the top of my head, is the
Japanese Pagodatree/Chinese Scholar Tree, Sophora japonica, which has
recently been changed to Styphnolobia japonica.
