Diaphragm anatomy in shrews: Whereas in mammals the diaphragm
is described to be a dome like muscle with central tendon, this tendon
is totally absent in those species which I have studied (Sorex araneus,
S. minutus, Neomys fodiens, Crocidura russula).
I have not seen this in other mammals and could not find any literature
with a comparative approach to diaphragm anatomy. Also I have not found
muscle weights of diaphragm for different species. Do you happen to have
knowledge on this issue?

Venom in shrews: I am particularly interested in the short-tailed
shrew as Mr. Nelson described it, "This large and fairly common shrew
is unusual because its saliva is toxic, allowing them to kill prey that
is larger than themselves. They have been known to kill garter snakes and
even young rabbits in the summer. .." (Boundary Water's Journal: Pukak:
Life Under The Snow, by Jon Nelson) "...I am interested in potential
human allergies or dangerous reactions as I frequently travel in the wilderness
where this shrew lives. I am wondering if there would be potential for
anaphylactic shock or what the first aid might be. I am also interested
in potential medical uses such as anaesthetics. I would be interested in
any direction that you could provide.

Is there anyone interested in swapping shrew skulls? I have
Blarina and Sorex fumeus specimens.
I have kept numerous individuals of Blarina and have found them to
be odoriferous, but fairly quiet. Last year I kept one that was positively
noisy. It screamed when the cage was disturbed - even to add food and water.
I have heard about them being "noisy mice" on a number
of occasions, but had never really experienced it.

Is it possible that large numbers of shrews (Sorex cinereus, and a
few Blarina brevicauda) one year could result in low numbers of Microtines
the following year? My trapping methods are as follows: Each trap station
contains three snap traps and one pitfall trap (to target shrews). When
I consider numbers of trapnights, do I include the pitfall traps in the

COPROPHAGY / REFECTION IN SHREWS:
The behaviour of licking the everted rectum in shrews has hitherto
been referred to as "coprophagy" or "refection". To
avoid confusion with "true" faeces-eating, we propose to persistently
use the descriptive term "rectum-licking" when referring to this
phenomenon. The behaviour is characterized by the animal everting the rectum
by a series of abdominal contractions and licking it in a curled-up posture,
apparently ingesting a yet undetermined substance often described as a
"milky white fluid".
This strange behaviour has hitherto been observed in 6 genera of shrews:
Crocidura, Myosorex, Neomys, Notiosorex, Sorex, and Suncus.
Has anybody observed this behaviour in other genera (e.g. Blarina or
Cryptotis) or in other insectivore groups?

- I am working with Don E. Wilson, Director of Biodiversity Programs
at the Smithsonian Institution, on "The Complete Book of North American
Mammals," which will be published by the Smithsonian Press.
- Right now we are trying to find good slides of every species that occurs
in the US and Canada, and we lack good, sharp slides of a number of species
of shrews. Do you by any chance have slides of any of the following that
we can use?
- Sorex arcticus - arctic shrew /Sorex arizonae - Arizona
shrew /Sorex bairdi - Baird's shrew /Sorex bendirii - marsh shrew /Sorex
dispar - long-tailed shrew /Sorex fumeus - smoky shrew /Sorex gaspensis
- Gaspe shrew/ Sorex haydeni - prairie shrew /Sorex hoyi - pygmy shrew
/Sorex hydrodromus - Pribilof Island shrew /Sorex jacksoni - St. Lawrence
Island shrew/ Sorex longirostris - southeastern shrew/ Sorex lyelli - Mt.
Lyell shrew/ Sorex merriami - Merriam's shrew /Sorex monticolus - montane

I am studying various viral and bacterial infections of small mammals
and am trying to locate someone who has any blood, serum or plasma samples
that they would be willing to use in a collaborative study. I need approximately
50 microliters to testper specimen. If you know of anyone please have them
contact me at GURRIGLASS@MSN.COM
or fax me at (410)955-0105 in the U.S.A. I would be happy to work out details

Information on montane shrews:
I am interested in knowing if the montane shrew (Sorex monticolus)
has ever been recorded for Owyhee county, southwestern Idaho. We recently
trapped two specimens in a shrubsteppe community in the Owyhee desert at
5880 feet. I also am interested in any information on published studies
of habitat association of the montane shrew. I am seeking this information
as it has been suggested to me that the shrews occurrence in our study
area, although not entirely unexpected, is unusual.
Thank you Jason Sutter

I have been working on small mammal communities in tropical forests
in south India for the past three years. My work has been in the high altitude
forest grassland systems that are a feature of this system. We have looked
at population dynamics, community structure, habitat use, competition and
Iwould like to get in touch with others who are working in the same
or similar fields. Are there any related web sites ? Since small mammals
in tropical systems is a relatively unworked area of research, I would
particularly like to discuss it with others who are doing the same thing.

The Transvaal Museum, Pretoria, South Africa and the Department of
Zoology and Entomology, University of Pretoria have begun an intiative
to account for the faunal biodiversity of southern Africa. We need to have
our first list of taxa reviewed by as many interested animal systematists
with expertise in southern African taxa as possible.
