HOMEPAGE OF MARK J. WETZEL

Welcome to my home page. I am a Research Scientist with the Illinois Natural History Survey, Champaign. On July 1 2008, the Illinois Natural History Survey – along with our sister agencies, the Illinois State Geological Survey, Illinois State Water Survey, and the Hazardous Waste Research Center (now the Illinois Sustainable Technology Center) transferred from the Illinois Department of Natural Resources into a new institute associated with the University of Illinois at Urbana-Champaign -- The Institute of Natural Resource Sustainability. In February 2010, the newly-formed Illinois State Archaeological Survey joined our Institute. On 11 May 2011, a new name for our group, the Prairie Research Institute at the University of Illinois at Urbana-Champaign, was established.

As an aquatic biologist, I collect and identify insects and non-insectan macroinvertebrates, and -- occasionally -- fishes, plankton, and unionid mussels that inhabit rivers, streams, springs, seeps, caves, other groundwater habitats, wetlands, ponds, lakes, and impoundments. I have a systematic interest and taxonomic expertise with the freshwater species in the Phylum Annelida -- the true-segmented worms. Groups in this phylum with which I am most familiar include the Aeolosomatida (suction-feeding worms), Branchiobdellida (crayfish worms), Hirudinida (leeches), and oligochaetes (the microdriles - primarily aquatic oligochaetes, and the megadriles - including most earthworms).

My primary responsibility at the Illinois Natural History Survey involves collaboration with several other aquatic biologists (an aquatic entomologist, a malacologist, and an ichthyologist) in the surveys of stream and lake systems that may be affected by construction or rehabilitation of bridge and highway projects by the Illinois Department of Transportation - throughout the State of Illinois. Through the conduct of these surveys, we document the current as well as historical status of both native and introduced aquatic fauna in these various habitats, with particular emphasis on species that are listed or under consideration for listing as endangered or threatened by the State of Illinois or the U.S. Department of the Interior, Fish and Wildlife Service. From 1991 until he passed away (September 2013), I had been collaborating with Dr. Donald W. Webb and other scientists at the INHS and the Illinois State Geological Survey in a long-term study of the biodiversity, hydrogeology, and water quality of springs in Illinois. Since the late 1970s, I have served as the curator and collections manager for the INHS Annelida Collection, which now holds close to 350,000 specimens representing all 50 U.S. states, most Canadian provinces, Puerto Rico, Bermuda, Mexico, and 14 other countries.

Other important research projects include the distributions of aquatic and terrestrial oligochaetes in the Huron Mountain area (Marquette County in the upper peninsula of Michigan) funded in part by the Huron Mountain Wildlife Foundation (2010-present), Great Smoky Mountains National Park, Grand Canyon National Park, and in spring, cave, and other groundwater habitats throughout the U.S.

For the last several years, I have been collaborating with Dr. John Reynolds (Oligochaetology Lab, Kitchener, Ontario, Canada) on several projects:
1) An annotated checklist of the megadrile earthworms of North America, published in March 2004 in the journal Megadrilogica [Vol. 9(11): 71-98].
In December 2008, we published an update of that 2004 paper in Megadrilogica [Vol. 12(12): 157-208], expanding its scope to include distribution records for earthworms occurring in Bermuda, Hawaii, Mexico, and Puerto Rico.
A second update was published in July 2012 in Megadrilogica [Vol. 15(8): 191-211]. In that paper we recognized 256 species representing 59 genera in 10 families; of these, 188 are considered native to North America while 68 are considered to be introductions.

2) In December 2011, we published an annotated checklist of the megadrile earthworms of Illinois in Megadrilogica [Vol. [Vol. 15(4): 35-67]. In that paper we reported records of 38 species earthworms (six families, 18 genera) from 79 of the 102 counties in the State; of these, 18 are considered native to North America while 20 are considered to be introductions. The type localities for eight of these species are in Illinois. We are now conducting surveys for earthworms in the 22 counties in Illinois from which no earthworm records had previously been reported or were available for review, as well as in other counties from which limited records were available. A second, updated paper on the earthworms of the state is projected for publication in 2014.

3) Nomenclatura Oligochaetologica – Editio Secunda website launched. On Monday 6 January 2014, Mark J. Wetzel (INHS) and John Reynolds (Oligochaetology Lab) launched a new website presenting the second edition of Nomenclatura Oligochaetologica, as

Nomenclatura Oligochaetologica Editio Secunda – a catalogue of names, descriptions, and type specimens of the Oligochaeta

This web-based Second Edition of Nomenclatura Oligochaetologica [N.O.2]: integrates the accounts included in the first volume (Reynolds and Cook, 1976 [N.O.]) with those presented in the three supplements (Reynolds and Cook, 1981 [N.O.S.P.], 1989 [N.O.S.S.], and 1993 [N.O.S.T.]) – together comprising the original N.O. series; updates and corrects accounts for the generic, subgeneric, specific, and infra-specific names of oligochaetes (Annelida, oligochaetous Clitellata) as presented in the original series; adds accounts for all oligochaete taxa described as new to science since 1993 – including barcode, GenBank, tissue repository, and other pertinent DNA sequencing information; expands the Index Auctorum, Index Auctoritatum, Index Museorum, Prolegomenon, Glossarium, and References sections of the original series; includes translations (in 11 languages) of the Prolegomena and Glossaria of the original series and this second edition; presents and expands Dedicatio sections in the original series with biographies and memoria for our historical and contemporary colleagues focused on oligochaetology, including bibliographies of their published scientific contributions; offers a forum for Current Perspectives in oligochaete phylogeny, taxonomy, systematics, and nomenclature; provides a Using This Nomenclator section with account examples and instructions for using and navigating this web-based catalogue; and includes an annotated list of links to web-based annelid resources.

4) John Reynolds and I are also conducting surveys for earthworms in the Upper Peninsula of Michigan (2013–).

5) as associate editor, I assist Dr. Reynolds with the editorial responsibilities of the journal Megadrilogica. A nagivator bar at the bottom of the journal's homepage provides links to an index of all volumes and issues published to date, tentative titles and authors for papers now in press, and links to a few other websites with information pertinent to the study of terrestrial oligochaetes.

The navigator bar at the bottom of this page provides links to other professional interests and to a diversity of annelid resources.


I have been a member of the International Symposia on Aquatic Oligochaeta (ISAO) group since its first meeting in 1979; in late 2007, I was elected to serve as the first General Secretary, ISAO.
Our 12th ISAO meeting, organized and hosted by Adrian Pinder, convened in Fremantle, Western Australia, 9-13 September 2012. Please visit the ISAO12 symposium website for additional information.

Our next / 13th ISAO meeting, which is being organized and hosted by Dr. Jana Schenková, will convene at Mazaryk University in Brno, Czech Repiblic, 7-11 September 2015. Please visit the ISAO13 symposium website periodically for updated information.



>> The Illinois Natural History Survey Biological Collections <<

The Illinois Natural History Survey Biological Collections are world-renowned and are among our institution's most important physical assets. Most notable are the insect, plant, fungi, fish, mollusk, amphibian and reptile, crustacean, mammal, bird, and annelid collections. These collections serve as an historical record of our living natural resources, are the basis for most of the work of identifying organisms for the public, and are critical to research programs focusing on the taxonomy, systematics, and ecology of plants and animals.

Specimens and data associated with our collections are commonly used by research, administrative, and regulatory staff members and educators throughout the state of Illinois, by the general public, and by scientists worldwide - either by visiting our institution or through loan programs overseen by our curators and collections managers. Environmental and ecological data associated with specimens and the assimilation of that information into computer databases has been completed for a few collections and is in progress for others. Web-based, searchable databases for several collections also are available to the public. You are encouraged to visit all of our collections - either via the links from this page and our main INHS webpage, or by arranging to visit our collections in person through contact with our collections curators and managers.

This photograph of me was taken by Dr. Steven J. Taylor during our collections for aquatic oligochaetes and other cave fauna in Fogelpole Cave (November 1999). Steve is an aquatic entomologist at the INHS, an avid caver, and an experienced biospeleologist with whom I have collaborated on a variety of projects. Please visit Steve's INHS Biospeleology Homepage to learn more about his interests, expertise, and research projects, view pictures of oligochaete worms and a diversity of other cave organisms, and be introduced to the study of biospeleology in Illinois, elsewhere in North America, and throughout the world.



This website was established in 1999; over the years, a simple stat counter tracked the number of visits per year. That stat counter recently ceased to function, so on 23 February 2010, I initiated the use of ClustrMaps.com to track the number of hits and also map the general locations of visitors, here:
