Declan McCabe Professor of Biology

Lorem impsum dolor


Ph.D. Ecology; University of Vermont
M.S.,  Ecology and Evolution; University of Pittsburgh
B.S., Biology; St. Joseph’s University, Philadelphia

Areas of Expertise:

My primary area of expertise is in the ecology of freshwater communities. My research with student collaborators is on the interactions among aquatic species, factors that affect biodiversity, and different ways to measure diversity.  Currently I am working on the restoration of natural function in forests and wetlands on Saint Michael’s College property.  My students are also using trail cameras to document coyote, bobcat, and other mammalian visitors to the Saint Michael’s College natural areas.

Courses I Teach:

  • Community Ecology
  • Evolution
  • General Biology

I am currently a Science Adviser for Vermont EPSCoR and I play two primary roles: I am a researcher in the Research on Adaptation to Climate Change project and I facilitate outreach to high schools in the Streams Project.  In 2011 the overall project was recently funded by NSF in the amount of $20 million.


Life Off Campus:

I grew up in Athlone, Ireland. I enjoy hiking with my son’s Boy Scout troop. My daughter’s Odyssey of the Mind team has made it to the world championships for two years running. I once was on the same plane with Gabriel Byrne; bumped into Trey Anastasio at Pizza Putt; I have seen Queen live in concert. My favorite course is Community Ecology, and particularly the laboratory portion that includes a series of hands-on research projects.

Recent News

Declan McCabe teaches biology at Saint Michael’s College and writes a regular nature column called The Outside Story, assigned and edited by Northern Woodlands magazine and sponsored by the Wellborn Ecology Fund of the New Hampshire Charitable Foundation. The column also has appeared for some years in several newspapers. Often he writes about research work with Saint Michael’s students, including several on a wide array of topics that he knows a lot about in recent months: plants, insects, small creatures, waterways and more! Also, in March, Declan was featured on WCAX, the Burlington-area CBS local news affiliate, during the morning newscast’s informative story by WCAX reporter Kevin Gaiss about the College Natural Area across Route 15 from campus. He told about a federal conservation easement to advance the site’s role as a natural laboratory for students. On April 9, central Vermont’s WDEV radio host Ric Cengeri invited Declan to come on his morning talk show and talk about beavers, a recent topic for the “The Outside Story” column.

Declan McCabe of the biology faculty in recent months has continued to write his periodic nature columns titled “The Outside Story” for Northern Woodlands Magazine and for several Vermont newspapers. Declan’s forthcoming book, Turning Stones: Life in Freshwater includes an essay about kingfishers and mussels where he thinks through a nature mystery like a logical biologist to reach a potentially satisfactory conclusion (also appearing as an Outside Story column. Also, this summer Declan started a new column for Northern Woodlands Magazine called “The Invertebrate Bestiary,” which comes out four times per year. He was invited to repeat his  trail camera talk on Zoom for North Branch Nature Center in May, retitled “Making the most of your Trail Camera”; and wrote a couple of pieces for The Other Paper in South Burlington about raccoons, and about trail cameras.” Finally, Declan got a nice mention on the website VT Kids in an item by Heather Fitzgerald.

Declan McCabe, professor of biology, has repeatedly captured wonderful wildlife photos with his trail cameras throughout the campus’s Natural Area in recent years, and a large crowd on the evening of February 24 learned technical and strategic tips from the professor on selecting, using and optimally deploying these outdoor cameras. Representatives of the event’s sponsoring group, Protect Our Wildlife Vermont, invited people of all backgrounds to engage in the program, both in pre-lecture publicity and during the talk. Declan reprised his talk for the March Saint Michael’s trustees meeting and it was well-received again. Elsewhere, Saint Michael’s students were front and center in the latest “Outside Story” column written by Declan. His work with student researchers on insect communities is funded by Vermont EPSCoR’s Grant NSF EPS Award #1556770 from the National Science Foundation. “The Outside Story” is assigned and edited by Northern Woodlands magazine and sponsored by the Wellborn Ecology Fund of New Hampshire Charitable Foundation. The column also appears in several Vermont newspapers. Declan also recently was invited to write a different ongoing series for Northern Woodlands. The first one already came out this spring, to be followed by seven more pieces over the coming two years. The series is called ‘The Invertebrate Bestiary’; “My guidelines are simply to write about interesting invertebrate … I love the freedom of this broad topic. Next one is submitted for the summer edition,” Declan shares. His first column was about water dragons.

Declan McCabe of the Saint Michael’s biology faculty worked this summer with a Vermont Youth Conservation Corps (VYCC) group of eight students from Burlington high schools plus their crew leaders, building steps on a steep part of the trail through the College’s Natural Area across Route 15. Since last report on faculty careers, Declan has continued to work with student researchers on insect communities in the Champlain Basin, funded by a Vermont EPSCoR’s Grant from the National Science Foundation. He continues to periodically write about those Saint Michael’s based experiences in his natural science column called The Outside Story, assigned and edited by Northern Woodlands magazine and sponsored by the Wellborn Ecology Fund of New Hampshire Charitable Foundation, and appearing in several Vermont newspapers and other regional news sources. Recent column topics since our last faculty news update have included mosquitoes, caddisflies and “snow fleas” aka springtails.

Declan McCabe, professor of biology, has continued periodically writing his nature column “The Outside Story” — assigned and edited by Northern Woodlands Magazine and sponsored by the Wellborn Ecology Fund of New Hampshire Charitable Foundation (and reprinted in several Vermont newspapers including at the link below from the Bennington Banner). One recent column told of his excursions out walking on the ice of Lake Champlain. It also describes a little of the science and chemistry behind the water molecules that freeze to form that ice, with valuable fact-checking and suggestions from his colleague Christina Chant, a faculty biophysical chemist at Saint Michael’s, as he notes in the column’s footnote. Also, each spring the University of Vermont Biology Department honors outstanding undergraduate students, graduate teaching assistants, and accomplished alumni for their achievements in the study of Biology. And Declan was among the honorees this year as an accomplished UVM biology alumnus (he earned his doctorate in the UVM biology graduate program). His students are continuing to accumulate mammalian community data based on camera traps in the 142 hectare Saint Michael’s College Natural Area. Research in this newly established natural area will most likely be Declan’s focus for the next several years.

Declan McCabe, associate professor of biology, recently was co-author of two papers along with students from the EpSCOR project (a partnership with the National Science Foundation to strengthen research and education in science). Declan has worked with EpSCOR for several summers directing a stream-research project involving students from St. Mike’s, the University of Vermont, Puerto Rico and elsewhere. The two recent papers appeared in the Biological Society journal Beta Beta Beta. The first was a research article, “Differences between kick sampling techniques and short-term Hester-Dendy sampling for stream macro invertebrates,” with three student co-authors including Erin Letovsky, daughter of St. Mike’s business Professor Robert Letovsky (Erin worked for the Biology Department for a time after her master’s); and then “Measuring standardized effect size improves interpretation of biomonitoring studies and facilitates meta-analysis,” with four student researchers. Declan also wrote a humorous but informative article, “The Case of the Giant Centipede and Flat Stanley,” in VES, the newsletter of the Vermont Entomological Society, telling of an encounter with some scary bugs — “pure fun rather than scholarship,” he says.

Declan McCabe, professor of biology, has had another paper published on a science education website called Scitable: Declan explains: “This one uses data gathered by the students in General Biology as well as research data collected by Vermont EPSCoR students working at Saint Michael’s College. The paper uses a combination of previously published data and novel data to illustrate the principles of sampling as applied to biological communities.” Scitable is a free science library and personal learning tool by Nature Publishing Group, the world’s leading publisher of science.
