You have probably seen this already, but in case not, in the Daily Telegraph for 21st November the following small article appeared "Fossil shrew puts evolution to the test"...inch long fossilised jawbone....Australia...rewrite history of mammals....owner there 110 million years before current theory...this fossil Ausktribophenos nyktos is 115 million years old...etc etc
Hope this is of interest.
Kind regards, Peter

Fossil shrew puts evolution to test
(Written by Aisling Irwin, Science Correspondent). Taken from: 'The Daily Telegraph', Friday, November 21, 1997 (issue no. 44,300), page 4.
AN INCH-LONG fossilised jawbone from a shrew-like animal discovered in Autstralia could rewrite the history of marnmals, palaeontologists claim today. The find, complete with four teeth, is the oldest mammal fossil found in Australia and indicates that its owner was there 110 million years before current theory says it should have been. Dr. David Archibald, a palaeontologist at San Diego State University, said "all hell would break loose", if the cleims made by the scientist who has analysed it, published in today's 'Science', are correct. The fossil turned up on a beach in southern Australia during a dig run by Dr. Thomas Rich, of the Museum of Victoria, Melbourne, and Dr. Patricia Vickers-Rich, of Munash University, Clayton. When they examined the jaw, they found that rather than being similar to Australia's pouched marsupials - the kangaroo and egg-laying monotremes, such as the duck-billed platypus - it appeared to be the ancestor of placental mammals. These mammals were not beiieved to have reached Australia until five million years ago, but this fossil, Ausktribosphenos nyktos, is 115 million years old. If the analysis is correct, it will revolutionise the understanding of where mammals first evolved und lived. Placental mammals were thought to have originated in Asia and then migrated to North America- If a placental mammal was in Australia more than 100 million years ahead of schedule then no one can say where th first evolved, said Dr. Cifelli. Other researchers are sceptical about the two scientists' claims and say more evidence is needed before redrafting the mammal's family tree.

2) Christmas Island Project: C. attenuata trichura
.
Date: Sun, 16 Nov 1997 14:57:24
From: Paul Meek <panres@ozemail.com.au>
.
Dear Colleagues,
I am currently writing a proposal for a study grant (Winston Churchill Fellowship) to undertake an international field visit in 1999. The Churchill Trust provides small grants to Australians to enable selected individuals to undertake research or conduct investigative projects of a kind not fully available in Australia. Since Christmas Island has the only Australian shrew species (Crocidura attenuata trichura), attempts to understand the ecology of this animal are extremely difficult. As such I plan to submit a proposal to conduct an investigative project to learn more about these strange animals. I have already contacted Peter Vogel who has kindly offered to make some time to see me in 1999.
I am keen to visit other researchers studying crociduran shrews, particularly in tropical parts of the world. If there are any researchers that fit the above description I would love to hear from them or about them.
Thank you

3) Shrew live trapping methods: Blarina carolinensis (Reply to L. Hartman, ST 1 / 16, Sept. 9, 1997)
.
Date: Wed, 19 Nov 1997 19:01:21 -0600
From: Joe Whittaker <joeshrew@siu.edu>
Subject: Re: Live trapping shrews
.
As far as trapping, I started off using pitfalls (2.4-L plastic cottage cheese containers without any drift fence) and a Russian designed and extremely sensitive live trap. Dr. Joe Merritt has used these Russian traps too. We borrowed one from Joe M. and built our own in one of our campus metal shops. I have a grid of 12 X 13 with 10 m between trap stations. I eventually gave up on the pitfalls, partially because of the labor required to keep pitfalls as live traps. I had trouble with them filling with water during sudden rainstorms and between trapping sessions. Between trapping sessions I would place pieces of bark or sticks in the pitfalls to act as ladders for shrews (etc). I had a lot of trouble with raccoons and opossum removing the sticks, which resulted in subsequent drownings of study subjects. For some reason coyotes also liked digging up the pitfalls and filling in the holes. In a "prestudy" of my current project (and after 7 months of trapping) I found no significant difference in Blarina captures in the Russian traps vs the pitfalls.
Currently I am using the Russian traps and small Sherman traps ( approx. 5.4 x 6.3 x 16.5 cm). Both of these traps have been working very well for me. Initially, the Russian traps had much higher captures, but the captures appear to be equalizing - maybe as the shrews get used to the idea of being trapped and released or as they develop a taste for the bait. I plan to look at initial captures to see if there is a difference, but haven't gotten around to it yet.
As far as bait, I've been using bread (first I freeze it so I can grind it up by hand) that is soaked in unrefined peanut oil (this was recommended to me by E. Ivanter, a researcher from the former Soviet Union) and mixed with cat food. I tried to get the cheapest and smelliest cat food I could find (chicken and fish). The bait is very smelly and the shrews appear to love it. I've been having extremely good luck with recaptures. Unfortunately, the bait also draws raccoons and opossum, and rather than letting them raid the traps, I've taken to actively trapping and moving them from the site. I usually put in a spoonful of bait. I've never tried mealworms, but they are used frequently in the literature.
Most of the Blarina carolinensis I see are approximately 9.5-g (7.5 - 12). They do very well with trap checks every three hours. I keep the traps open for 24 hours and do the 3-hour checks. I usually try to trap for 2 24-hr periods twice a month. I've had very low trap mortality, and most of what I have had has been due to accidents, such as getting into a trap between sessions (if something knocks a Russian trap over, the door may open) or stuck in the door of the Sherman trap. Depending on the weight (and metabolism) of your water shrews, you may need to check the traps more often, especially if they are red-listed. I'm not sure what your trapping experience is, but I handle the shrews pretty much as I would a mouse or vole. I grab them by the scruff of the neck and hold on. Unlike mice, Blarina are extremely squirmy. I usually dump the shrew out of the trap into a plastic bag and grab them through the bag, that way if I feel them start to get loose I can drop them back into the bag. When using pitfalls, I would turn a plastic bag inside out (making sort of a glove or mitten) and "grab" the shrew and then pull the bag back up over my hand. I finally did get bitten with this technique and started using a glove with the plastic bag to remove them from the trap.
A couple bits of cautionary advice. In my trapping both at my current and the pre-study site, it took a long time to get my first shrew capture. In the case of my current site, it was several trapping sessions. After a few months I had a few individuals I would occasionally recapture and then rather suddenly I was inundated. A couple of weekends ago, I had a total of 84 captures of approximately 27 individual shrews. So I guess I would strongly recommend pre-baiting and being patient. My advisor and I even started planning an alternate project - fortunately the shrews came through for me. I also recommend a smelly bait.
I did my Master's degree in Minnesota and knew some people working with water shrews up there. They had success using longworth traps and minnows as bait. They would look for runways along creek banks and use a wire (coathanger) to build a support for the trap over the water. Basically they would place the door of the trap where the runway ended, with the body of the trap just above the surface of the water.
I hope this is helpful for you. I'd be interested to hear how things turn out. If there is anything else I can do to help, please let me know. I've never caught anything besides Blarina (as far as shrews that is - I get mice and voles too) in the Russian traps, but if you are interested in seeing the trap I may be able to send you one. If you have a large budget you may want to try building them. I can tell you more if you want to look into it.

Subject: play behavior

I discovered your "shrew-ist's" site, and was wondering if you might be able to direct me towards research concerning play behavior in shrews. Material regarding development or exploration may also be helpful.
Thanks for your time, Israel Christie University of Tennessee

Hi Israel, There is hardly a mentioning of play behaviour in hitherto shrew studies, although I could retrieve two references by searching 'The Shrew Bibliography'. Fagan's book merely refers to it in a few sentences. The literature on shrew development and exploration (eg caravanning) is more abundant and to find out you would have to be more precice on what you are looking for.

Subject: Re: mealworms and shrews
.
You probably are doing this already but it is very easy to maintain a colony of mealworm larvae to provide food for the insectivora. In a 20 gallon terrarium I can maintain several hundred insects in various life stages using a bed-o-cob substrate and dried flower, cornmeal,cereals etc for food. Add an apple or potatoe once in a while for moisture. The terrarium should be kept in the dark. Canned dog food can be used to some extent to feed moles and shrews as well, in captivity.
