Re: [ECOLOG-L] Different results from Statview and SPSS
This occurs when you calculate mixed effects models. The statistics programs make different assumptions about the error structure and therefore calculate different F values. This is described in Ayres, M. P., and D. L. Thomas. 1990. Alternative formulations of the mixed-model ANOVA applied to quantitative genetics. Evolution 44:221-226. Hocking, R. R. (1973) A discussion of the two-way mixed model. Amer. Statist. 27:148-152 McLean, R. A., Sanders, W. L., Stroup, W. W. (1991) A unified approach to mixed linear models. Amer. Statist. 45: 54-64 At the time when I needed this I talked the issue over with Dr. Brunner, Professor in statistics at the University of Göttingen. He recommended not using the SAS-formulas because they are based on the assumption of negatively correlated interaction terms which he thinks is not very likely. I deal with the issue by having my stats program (JMP) calculate the sum of squares and then calculate the rest in Excel according to the formulas recommended by a stats book I trust (e.g. Kirk, Winer, or Zar).

The two programs produce different sums of squares and utilize different degrees of freedom for the independent variables, thus producing very different p-values. Has anyone working with these two programs run into anything similar? BTW, if I run the ANOVA with no covariate, the sum of squares and F-statistic and p-values match up between Statview and SPSS.

Re: [ECOLOG-L] Plagiarizing methods...
Hi Malcolm, You know, some of the problem may be a case of bad habits among those using PCR techniques (and other research tools, since it isn't just a PCR problem). Published papers are not citing the original paper that came up with the whole idea. They are not citing a standard lab manual. I've requested my students to do one or the other and then explain the changes. My students, looking at the papers in their field, seem to think that's not the way to go. Instead, everyone (published papers, my students) is 'reinventing the wheel' and redefining the wheel--all without citation. In fact, in summarizing Ecolog responses to my class last night, that's what I told them. I suggested that they should find the original PCR paper. One reason I gave is that since everyone is citing more recent papers, maybe some errors have crept into the entire protocol. It's all part of doing the library research of your research project--you have to check and confirm and the best way is by digging out the original papers. So, I agree with you. I guess the bottom line of all this (talk about an idiom-filled email) is for me to be more confident in insisting my students try it the right way: cite and explain any changes.

[ECOLOG-L] geolocators
Hi fellow loggers, I have a question or a few questions about geolocators. Have any of you used them, who produces them, what is their resolution or how accurate are they? From my limited understanding I gathered that they are not within meters correct, but more so within many km (100s?)? What was your experience with these geolocators?

[ECOLOG-L] PhD Assistantship - remote sensing and GIS - Rhode Island
The Department of Natural Resources Science, University of Rhode Island, is recruiting a Ph.D. student who will conduct research in habitat suitability assessment and predictive modeling using remote sensing data and GIS analysis. This research project will focus on the relationship between ecological conditions of the Appalachian National Scenic Trail (A.T.) and the impacting factors such as land-use and land-cover change and climate change. The graduate student should have a strong background in remote sensing and GIS and a strong interest in biodiversity, wildlife habitats and management. The assistantship is provided by a NASA-funded project that will develop a decision support system for monitoring, reporting and forecasting the ecological conditions of the A.T. MEGA-transect. This decision support system will integrate multi-platform remote sensing data, Terrestrial Observation and Prediction System (TOPS) models, and in situ measurements for understanding the ecological conditions of the A.T. land and for conservation of biodiversity. Expected starting date: Fall 2009 semester or Spring 2010 semester. The graduate student will work under the supervision of Dr. Y.Q. Wang. Please submit a letter of interest, CV, transcripts and GRE scores and the names of 3 references to Professor Y.Q. Wang (yqw...@uri.edu). Review of applications will begin immediately and continue until filled.

[ECOLOG-L] Book recommendations and opinions needed
In light of my recent request for information about Rusty Crayfish and invasion biology theory, I would like to hear from you folks some book titles regarding Nonequilibrium Ecology. I am more interested in concepts and theories than in charts and graphs. I have a handful of Stephen Jay Gould's books (including Punctuated Evolution) and have begun some other titles, but am looking forward to your suggestions. My other question (which I hope will prompt some honest discussion and not upset anyone) is: Can one be a biologist/ecologist without being a conservationist or preservationist?

Re: [ECOLOG-L] Plagiarizing methods...
As some research techniques become widely popular and standardized, I don't find any reason to cite the original paper. Nobody cite William Sealy Goseet for t-test, Ronald Fisher for ANOVA, or Howard T Fisher for GIS. In fact, you need to dig up a history book to find out who is the original inventor. PCR method was innovative when it came out in mid 80s. But, it has become widely popular on these days. Even a high school student with a PCR machine can do this. In fact, this is a cookbook method now. http://en.wikipedia.org/wiki/Polymerase_chain_reaction When a research method is taught at undergraduate level, I don't think I need to cite the original paper for a publication. I use this rule of thumb. Does anyone have other rule of thumb for citation of a method?

Re: [ECOLOG-L] Plagiarizing methods...
Hi Cara! Seems to me that you should go with your real mind (aka, your gut) and make sure your students, at least, don't develop habits of lazy scholarship that seem to be creeping in everywhere and contaminating all sorts of literature with ripples of error that can become tsunamis. Certainly there is no need to go to absurd or irrelevant lengths to cite original research merely for decorative purposes (especially if the student hasn't read or really isn't citing the original research but just using a lab manual), but if the context calls for it there should be zero tolerance of sloppiness--or phoniness.

[ECOLOG-L] Plant defense literature
Ecolog, I'm a recent biology graduate with an interest in plant defense and planning on applying to graduate school in the fall. Before I apply I would like to read more literature on the subject. I'm particularly interested in theory as well as papers about chemical defenses and plasticity. Aside from defense, I am interested in plant strategy as a whole. If anybody has suggestions for papers or books for me to read I would greatly appreciate them! Thanks a lot! Todd Johnson Moravian College 2009 sttd...@gmail.com
