Dear Werner,
>Conservation Action Plan). I have made offers to extend this network to the >IUCN / Insectivore Specialist Group. I would very much appreciate receiving >any comments from the IUCN members. What can be done for the conservation >of threatened shrew species? How can we help? The Shrew (ist's) Site would >be willing to act as a mediator and a possibility for fund-raising.
I am a member of the IUCN, though not a shrewist. I'm in the SSC/Tapir Specialist Group. I'm fairly new to this organization. One of the things I like best about the IUCN is the amount of autonomy given to groups within the organization, and to members within the groups. However, this can have its downside as well as the positive aspects - depending on the people involved. In the end, a lot depends on the Chair and members of the Specialist Groups. The IUCN itself offers a framework, provides guidelines and mentor-like help. The rest is up to individual initiative - and you know what that can mean - good things happen, or disaster (i.e., nothing happens).
I noticed that the Insectivore and Tree Shrew groups did not contribute anything to the June-December "Species," the bi-annual newsletter (153 pages this time) where groups tell what they're doing and have done recently, and generally try to post a state-of-the-conservation message on their species. Possibly the group is not very active right now? I'm sorry, I don't know more about this particular subset of the SSC. Whether they respond to your offers or not, you are doing tremendous work for the shrews; my personal opinion is that having an alliance of some type would benefit the people involved and the shrews.
Best wishes,
Sheryl Todd

2) Onset of breeding season in Myosorex varius

Dear Werner,
...now i have just returned from Grahamstown SA where I have been working with Mike Bedford and Ric Bernard on the fertilization events in Myosorex varius and on Saturday I head out to the field.
As you know, most of my recent work deals with rodents but recently I have discovered indications of fostering in M. varius. During October I was trapping as part of an on going project but I had out extra traps in order to collect shrews for the Mike Bedford fertilization study. That particular field trip also filled in an important gap in my data on the onset of breeding in M. varius. There were very good mid-winter rains (this is most unusual) and the breeding started just after mid-winter. Other data I have from four other sites in SA confirm this - but at this particular site I have variable data depending on the onset of the rains. I want to write this up in the next few months.
Many thanks for Shrew Talk - I find many of the postings interesting and I am hoping to index my collection of the newsletter because I now find I cannot remember all that they contain. I will add the postings onto my bibliographic database to achieve the necessary cross-referencing.
Best wishes Rod

3) Baiting shrew traps: An appetizer for raccoons... A reply to Stuart Niven (Shrew Talk 1/25)

In my trapping with smelly bait I have also run into problems with raccoons, skunks and opossum. Prior to and during my small mammal trapping I set large Hav-A-Hart traps for the medium-sized mammalian opportunists. Once I trap them, I relocate the pesky opportunists. This removal trapping in concert with frequent trap checks has worked well for me. The students would probably enjoy seeing the medium sized mammals too. The skunks in particular are interesting.
Personally, I would not recommend cutting holes in aluminum live traps. Here in Illinois I've seen rice rats and Peromyscus spp. easily chew through and enlarge holes in small Sherman traps. We've even had some mortality from animals getting stuck and suffocated trying to get through holes.
Good luck with the raccoon battle.

4) Baiting shrew traps and use of drift fences A reply to Julie Fuller (Shrew Talk 1/25)
Date: Wed, 3 Dec 1997 14:05:07 -0600
From: Joe Whittaker <joeshrew@siu.edu>
Subject: Shrew Talk
As far as baiting my pitfall traps I usually just place a lump of bait into the pitfall. Since I keep them dry this works well. Since you will be keeping water in them you may need to come up with something else. Maybe you could float the bait on little pieces of styrofoam, wood or something. A lot of the pitfalls with water I've seen get fairly smelly on their own quickly as invertebrates and herptiles fall in and die.
As far as drift fences, they are simply a strip of aluminum flashing (or like material) which can be erected to serve as barrier to normal movements and "funnels" animals into a pitfall. There are numerous sources which describe drift fence use and I have included a couple citations you should be able to get from your library:
Prince. 1941. Water traps capture the pygmy shrew (Microsorex hoyi) in abundance. The Canadian Field-Naturalist, 55:72.
Mengak and Guynn. 1987. Pitfalls and snap traps for sampling small mammals and herpetofauna. The American Midland Naturalist, 118: 284-288.
Gibbons and Semlitsch. 1981. Terrestrial drift fences with pitfalls: an effective technique for quantitative sampling of small mammal populations. Brimleyana, 7:1-17.
The following papers appear in Merritt, J. F, G. L. Kirkland, Jr., and R. K. Rose (ed.s), Advances in the Biology of Shrews. 1994. Carnegie Museum of Natural History Special Publication No. 18. Pittsburgh, PA.
Kirkland and Sheppard. 1994. Proposed standard protocol for sampling small mammal communities.
Handley and Varn. 1994. The trapline concept applied to pitfall arrays.
If you have trouble getting these last two let me know and I can mail you a copy (they are both fairly short and they provide a good review of pitfall literature).
I meant to send Werner Haberl at SHREW TALK a copy of my last message to you and deleted it by mistake. If possible could you send him that correspondence? I'll send a copy of this to him.
Good luck with the project and let me know if I can be of further assistance.

5) Re: Trapped shrews in discarded bottles A reply to Dick Davis (Shrew Talk 1/25)
Date: Wed, 3 Dec 1997 14:57:21 -0600
Subject: Re: SHREW TALK: Vol. 1, No. 25 - 02 December 1997
Dear Dick,
Concerning shrews and bottles, you may be interested in a paper "A comparison of two survey methods for shrews: Pitfalls and discarded bottles" from 1990 that was in American Midland Naturalist 124:191-194. We found the remains of 290 shrews of three species in 72 bottles (mean per bottle = 4; range 1-39). Relative frequencies of shrew species from discarded bottles were significantly different from those determined by pitfall trapping in the same area.

6) Re: Identifying shrew species without killing them A reply to Steven Petersen (Shrew Talk 1/25)
Date: Wed, 3 Dec 1997 15:23:04 -0600
From: Joe Whittaker <joeshrew@siu.edu>
Steven Petersen,
I saw your information request in Shrew Talk and wanted to respond. I'm not sure if you saw what I had sent in as a response to a request from Lisa Hartman. It is mainly concerned with methodology I've been using in a mark-recapture study of Blarina carolinensis. (Shrew Talk Vol. 1/24, November 24, 1997).
As far as identifying your species (Sorex cinereus, S.hoyi, S. monticolus, S. arcticus, and S. palustris), I know nothing about S. monticolus, but S. articus and S. palustris should be fairly distinct based on size and pelage characteristics. The problem I forsee would be between S. cinereus and S. hoyi. I would recommend keeping a blunt probe and a hand lens with you in the field. It should be possible (in theory) to attempt to check the shrews' teeth without killing them. When I started my Ph. D. project here I had hoped to employ this methodology with southeastern shrews (S. longirostris) and S. hoyi. The two of them can be differentiated by medial tines and upper unicuspids.
Let me know if I can be of any further help. Good luck with your project,
Joe Whittaker Zoology Department Southern Illinois University Carbondale, IL 62901
1) Shrews in the house / Virus alert?
From: Richard C. Lehr <RCLehr@aol.com>
Date: Fri, 5 Dec 1997 23:02:58 EST
Subject: Re: shrew in the house & hanta
Came across your website and wondering if you had some answers. I live south of Helena Mt. USA, at 5800 ft. in the Helena National Forest. We have had a deer mice problem in our house which we have been fighting,(and losing I might add), until recently when my traps have not produced any mice. What they have caught are shrews! Not on a steady basis, but 3 over a period of about 9 weeks. I know virtually nothing about them. Do they eat mice? Do they infest houses similiar to mice? We are presently still finding ways to combat the mice because of Hanta Virus. Do shrews also carry the virus? Any information would be greatly appreciated.
While not a student, reasearcher, or involved in work of any kind with these small mammals I am facinated about the world of animals in which I live, even the smaller ones. I live in the mountains and love watching the wildlife----at times I feel that I am the being observed instead of the other way around. I look forward to future topics. Once again thank you.

Diplomesodon pulchellum:(...) It occurred so that I was the first helminthologist who examined helminths of this shrew. I did it on the fixed materials from Kazakhstan and my colleague from Turkmenistan examined freshly caught animals. We described four new tapeworm species from it (references are marked with asterisk). All cestodes of D.p. occurred to be specific and new! I have no photo of this shrew. However, some data are given in the Volume 4 of the "Mammals of Kazakhstan" (in Russian). Hope you know about that book.

    Die Erforschung der Spitzmäuse (Mammalia: Insectivora: Soricidae) hat während der letzten zehn Jahre einen immensen Aufschwung erfahren, wobei sich der Autor selbst intensiv mit dieser Gruppe beschäftigt. Die vorliegende CD stellt eine sehr wertvolle und umfangreiche Datenbank der relevanten Literatur dar. Enthalten sind auch Felder wie "abstracts" und "keywords", die eine effiziente Suche nach bestimmten Themen ermöglichen. Zeitschriften und Bücher zu verschiedenen Themen (Ökologie, Verhalten, Anatomie, Histologie, Genetik, Physiologie, Räuber, Parasiten, Paläontologie, Reproduktion, Entwicklung, Ultrastruktur, Zytologie, Medizinische Forschung, Systematik, Taxonomic, Evolution, Fang und Methoden, Zucht im Labor, Zoogeographie, Schutz etc.) als auch nicht publizierte Daten (z.B. Beiträge auf Treffen, Dissertationen, Thesen) wurden berücksichtigt. Die Datenbank liegt in mehreren Formaten vor. Befindet man sich im Besitz von Microsoft Access, so ist der Zugriff ein Kinderspiel. Ist dies nicht der Fall, erfordert es einige Fachkenntnisse, die Daten für den Anwender nutzbar zu machen. Trotz dieser Schwierigkeiten ist diese Bibliographie eine zu empfehlende Anschaffung für jede größere Zoologische Bibliothek und den Spezialisten. Der relativ hohe Preis ist durch den großen Aufwand des Autors und die niedrige absetzbare Stückzahl durchaus gerechtfertigt. Es ist zu hoffen, daß diese Bibliographie in regelmäßigen Zeitabständen eine Überarbeitung erfahren wird.
