PUBLIC INFORMATION PAGE SERIES (LINKS)
The list below represents a series of public information pages I will be creating to address commonly asked questions about biological issues—particularly issues and questions about vertebrate animals that I have direct or personal knowledge of. I have been motivated to create these pages because of running across web pages that purport to provide 'answers' to people's questions about animals, evolution and biology generally. While some of the information available on the web is reasonably accurate, I have found that most of it is misleading or downright erroneous. The 'answers' are usually written by people who, although good-intentioned, are mostly ignorant about the topics they address. In any case, the information is nearly always cobbled together from secondary and tertiary sources of information—or worse—rather than direct knowledge of the science or the primary literature on the topic. The aim of these pages, therefore, is to provide accurate, scientifically validated information on some topics in my areas of expertise that come to my attention as being of general interest. I was motivated to do this mostly because of the widespread misinformation being propagated on the web about the first question, below. Since the information used to 'answer' this question is almost always based on a distorted or misunderstood representation of my own research, it seems appropriate for me to set the record straight.

MAJOR RESEARCH INTERESTS
- Phenotypic evolution
- Evolutionary constraint
- Evolutionary and functional morphology of vertebrates
- Evolutionary and functional morphology of feeding in tetrapod vertebrates, especially lizards
- Evolutionary and functional morphology of chemoreception in lizards and snakes
- Evolutionary and functional morphology of the vertebrate tongue
My research program is three-pronged: I pursue empirical studies related to the functional and evolutionary morphology of squamate feeding and chemoreception, and theoretical work related to phenotypic evolution and evolutionary constraint. Feeding and chemoreception are functionally and evolutionarily related in squamates owing to their shared use of a single, complex organ, the tongue. From a biomechanical point of view, optimization of the tongue for feeding function makes it less effective in (vomeronasal) chemoreception and vice versa. Thus, there is a classic functional (and evolutionary) trade-off between the two principal functions of the tongue. Phylogenetic character analysis reveals how each major clade of squamates has found a unique 'solution' to the problem of this trade-off. The dynamic nature of the evolutionary tension created by competing sources of selection pressure has led to my theoretical work on internal selection, functional integration, phenotypic stability and evolutionary constraint. Much of this work has been done in collaboration with Günter Wagner at Yale University. Although theoretical, the work is firmly grounded in my empirical work on squamate feeding and chemosensory systems, which have proven to be compelling model systems for approaching these broader issues.
INFORMATION FOR PROSPECTIVE GRADUATE STUDENTS
Students in my laboratory develop their own, independent research programs under my supervision. Although I expect there to be some overlap or mutual interest in student projects, I do not require students to work in my specific research areas. Ideally students will incorporate elements of morphology, evolution and/or function into their projects. Purely ecological or conservation-related projects are discouraged (because they lie outside my areas of expertise), although these can be elements of a research program centered on the former topics. Although I am best able to supervise work on squamate reptiles, I am open to projects dealing with any vertebrate group. I principally do laboratory-based work, but recent graduate students have included significant field components in their research. Applications from potential doctoral students are preferred, but doing a Masters is also possible.
The Department of Ecology and Evolutionary Biology at UConn is very integrative and interactive, and there is a great deal of cross-fertilization among labs. The department comprises 30 full-time faculty, all of whom work in the general area of organismal biology. There are an additional 60+ biologists in our sister departments of Physiology and Neurobiology, and Molecular and Cell Biology - and this is not to mention a variety of wildlife biologists in the School of Agriculture, biomedical researchers in the School of Medicine, etc. Thus, there is virtually no area of expertise unavailable to students when they assemble their research advisory committees.
There are eight vertebrate biology faculty in the department (4 herpetology, 2 ornithology, 1 ichthyology, 1 mammalogy), and along with postdocs, graduate and undergraduate students, they constitute a very active and interactive research group. We have informal weekly meetings called Vertlunch in which we read and critique recent papers (and laugh a lot) and every Friday at 4:00 the Schwenk and Rubega labs (and others) meet for Beermorph in which - well, it's pretty self-explanatory. For those morphologists with a developmental bent, we also have sporadic meetings of an Evo-Devo Journal Club in which we read and discuss current literature. And this is not to mention, of course, the frequent graduate seminars on various topics offered by faculty in the department, as well as weekly departmental seminars and occasional 'Tuesday Evening Seminars' run by the EEB graduate students. All-in-all, a very active place where you can be intellectually challenged and exposed to a variety of viewpoints - often while drinking at the same time.
Before applying directly to the department for admission into the graduate program, you should contact me by email and describe your research interests and goals so that we can determine if there is an appropriate match. You should also explore the departmental web page to get as much information about EEB as you can. If you have any questions at all about the department or the University, don't hesitate to email me. I can also put you in touch with current graduate students if you would like to hear about the program from their perspectives.
Students accepted into the doctoral program are guaranteed 5 years of support (mostly by means of Teaching Assistantships). Support beyond 5 years is usually possible for students making good progress, but is not guaranteed. Masters students are guaranteed 2 years of support. The support package includes a tuition waiver and full health benefits.
NSF/SICB INITIATIVE: GRAND CHALLENGES IN ORGANISMAL BIOLOGY
At the January, 2009, annual meeting of the Society for Integrative and Comparative Biology (SICB) in Boston, William Zamer of the National Science Foundation challenged the Society to determine what the 'grand challenge questions' are for future work in organismal biology. As the largest comparative, organismal professional society in the country (and probably the world), SICB was called upon to organize organismal biologists to help shape future funding in the field by identifying integrative and forward-looking research arenas that would not only contribute to basic knowledge in organismal biology, but would also tie-in with interest-areas targeted by the Obama administration. SICB President Rich Satterlie called a series of meetings and discussions among the SICB Executive Committee, and on the basis of these discussions, a four-person subcommittee was appointed, with me as Chair, to produce a brief, initial document to be distributed among NSF staff immediately (as required by NSF's budget meeting schedule). This draft document has been expanded into a full-length manuscript that appeared in the first 2009 issue of the Sociey's journal, Integrative and Comparative Biology. Subsequent issues of the journal feature additional 'perspective' pieces written by other organismal biologists targeting more specific topics. The aim of the documents posted here, as well as the other essays published in ICB, is to stimulate broader discussion in the field about future research initiatives and novel, collaborative and synthetic research directions. SICB (and NSF) hopes that additional discussion will further develop and refine the 'grand challenges' in organismal biology. In the near future, face-to-face meetings are planned to broaden and extend the initiative, and these meetings, it is hoped, will lead to concrete advances and funding opportunities for organismal biology, an area that has been chronically underfunded for many years.
The 'grand challenges' initiative is presently in full swing. Additional essays on organismal biology are appearing regularly in ICB and workshops wer held at the 2010 and 2011 annual SICB meetings directed at broadening participation and developing methods for implementation. I have contributed my own ideas with regard to the latter in an invited BioScience essay (below).
