Subject: Shrew Talk - Preble's shrew or Preble's jumping mouse?
A person wrote in recently asking about Preble's shrew at the Rocky Flats site in Colorado. I thought the creature of concern at the former nuclear weapons factory was Preble's jumping mouse, a subspecies of jumping mouse previously found throughout the Front Ranges of the Colorado Rockies, but now restricted to the Rocky Flats site. The story is that the mouse requires good-quality grasslands, which have been grazed out of existence everywhere within its range, except around the well-fenced-off weapons plant- proof, some would say, that cows are more dangerous than nuclear weapons!

The title of my dissertation is:
Distributional Ecology of Terrestrial Micromammals based on Resource Preferences: Field Studies in Northern California. 152 pp. Accepted by the Office of Graduate Studies of the University of California, Davis in June 1997.
The following synopsis of my dissertation is for your information or use as you see fit. Major players in my research included Sorex vagrans, S. trowbridgii, S. ornatus, and S. palustris. A few Sorex specimens were not referable to any know taxa for the area (personal observation and in discussions with Dr. Bob Hoffmann & Jesus Maldonado).
I recently completed the Ph.D. in Population Biology at the University of California at Davis. My advisors were Drs. Thomas W. Schoener (chairman), James Quinn, and Peter Moyle. My dissertation research involved characterizing a community of micromammals (shrews, moles, and rodents) near Mount Shasta volcano in extreme northern California in terms of their preferences for riparian versus upland habitats. I used these characterizations to extend the traditional island biogeography perspective of habitat quality to a landscape perspective in which habitats are allowed to vary continuously (including all levels of suboptimality) rather than only dichotomously as in traditional island studies (optimal or uninhabitable). My results suggest that the importance of size and isolation of optimal habitat patches has been overemphasized in terms of importance for conservation relative to the importance of other factors, such as autecological and synecological forces. This research offers a means of pursuing issues of conservation strategy to a landscape level more indicative of real world situations than has previously been typical.

3) A question on shrew venom
Date: Thu, 11 Sep 1997 14:05:37 -0700 (PDT)
From: HAROLD KISANG KIM <jordan23@ucla.edu>
I'm presently taking vertebrate morphology at UCLA and I asked my question about how poisonous shrews prevent the neurotoxin from being self-reactive, my professor didn't have the answer but I was wondering if you could elucidate on the issue.
Thank you, Harold Kim
4) Shrew Molars & Iron pigmentation
Date: Thu, 11 Sep 1997 11:53:49 -0400
Subject: Shrew Molars & Iron pigmentation
Organization: marshall university
Guten tag! I am in urgent need of a list of articles (in English) on the iron pigmentation in shrew molars, its evolutionary significance, and any density studies of those molars. Thank you for any assistance you may offer.
Please send any info to GARDNERW@MUSOM01.MU.WVNET.EDU.
