I have had requests for the correspondence that ensued. I thank all of the people who helped me. I have collected the correspondence into a file which I am attaching to this note. A number of people have requested the information from the file. I hope it helps other investigators. Yours truly, Dick Brugam The file of correspondence on diatoms as depth indicators is: ********* From lkd653@anu.edu.auTue Aug 20 09:41:38 1996 Date: Sun, 20 Aug 1995 21:35:12 -0200 From: Leanne Armand To: Richard Brugam Subject: Re: Variation of species composition of diatom communities with depth Dear Richard, I will get send another message on Friday, with a couple of references that I can think of but don't have handy. I work (PhD)in the Southern Ocean on diatoms in the sediments, and if I remember correctly one of my supervisors did some factor analysis on water depth relationship to the fossils in the sediments for his PhD - but he didn't find anything conclusive. But this isn't what you are after exactly since you want to relate distribution with water depth - I think your problem might be that there isn't enough known about specific diatom life cycles and so it will be difficult to seperate a diatoms preferred depth versus oceanic processes acting on the distribution. I guess I also need to know if it is oceanic distributions you are interested in also ?

If you would like a copy of this, please let me know. As you have already probably found there are a number of papers around that talk about diatom variations to differing light conditions and sediment type (environmental parameters that vary with depth). If I can offer anyŠsuggestion, feel free to ask. regards, Jason Whitehead.

Diatoms/depth has been one of main research topics for the past few years.

I have a manuscript that is prepared for submission to J. Paleo. that I could send to you soon. There are a number of papers that relate species composition to water level within particular lakes but few that compare communities among lakes of differing maximum depth. I will get my list together and forward it to you. Could you send me any references you receive? Thank you.

I have a calibration data set from the Pocono's and the 3 significant variables in Canoco were depth, pH, and latitude. I have tried doing depth reconstructions but the numbers turn out crazy. I am working on a second draft of a paper on the Pocono calibration data with Don Charles. Colleen Prather, a PhD. student here with Mike Hickman also had depth as a significant variable in an Alberta calibration set. As I recall she didn't have much luck reconstructing depth either. I don't know if any of her stuff has been published. I think there is a discussion of some taxa prefering deep water in the Anderson et al. paper in J. Phyc on the PIRLA New England data set. Let me know if you have any questions about the Pocono stuff, I can give you more specifics if you want. Jackie Hello Dick Brugam, I am also planning to do some diatom/water depth interactions by looking at fossil diatom assemblages. I sent out a similar request about a year and a half ago, although I am still in the throes of getting my research project off the ground. The response that I got included Barker et. al. 1994 (J. paleolim), Yang and Duthie 1995 (J. Great Lakes Research), Oviatt et al. 1994 (J. paleolim), Wilson et al. 1994 (J. paleolim). Stevenson and Flower 1991 (Biol. Conserv.) and Lebo et al. 1994 (J paleolim). If you would like more info on any of these, let me know. Also, I would be interested in hearing about any new work along these lines. I am doing a historical study of the Everglades to look at changing hydrologic regimes with the construction of canals and dikes, etc. Best wishes, Sherri Cooper Duke Wetland Center Box 90333 Durham, NC 27708 (919) 613-8007 FAX (919) 684-8741
