CRI Funny

This comes to us from a previous lab member for Deb MacLatchy at Laurier, Jen Ings.

She was in the lab one day during working on her project, and a professor was giving a tour to his young son. He pointed out the tanks and said, “In these tanks are fish called mummichog.”

The boy replied: “If these are all the mummichog, where are the daddy-chogs?”


Recent Happenings - Baird Lab

An exciting international SETAC workshop on Trait-based Ecological Risk Assessment (TERA) was hosted by Environment Canada at the CCIW in Burlington from 7th -11th September 2009. Donald Baird, Joseph Culp, Tim Pascoe, Paul van den Brink, Steve Maund and PhD. Student Mascha Rubach organized the workshop because of our realization that taxonomy‐based descriptions of natural systems place limitations on our ability to describe ecological responses to stress. The workshop particularly identified problems associated with potential trait ontologies in order to take the first steps towards developing a collaborative platform for sharing trait information. As a first and immediate result in order to start a web-based ontology for traits in this field, we created an online community at

Recent Happenings - Courtenay Lab

Allan Debertin is back from working aboard the Canadian Coast Guard Ship (CCGS) Opilio for his field research. The research survey of the Northumberland Strait this year was very successful due to good weather and very few equipment problems. 234 sites were sampled in the Strait this year as far West as Escuminac point, NB to areas East of Souris, PEI. Many thanks extended to the captains, crew and field assistant Jesse Kelly for their help with this project.

Mike Sweezey has been continuing work this summer studying American eel on the Upper Salmon River in Alma, New Brunswick. He has used various telemetry techniques including passive integrated transponder tags and radio tags to track the movements of individual eel in the system throughout the summer. Mike has found that eel captured in freshwater in the spring have migrated to the saltwater estuary which they have utilized as a summer feeding ground. Mike will continue to tag and track individual eel this fall to determine what habitat they will utilize as overwintering grounds (i.e., will the eel stay in the saltwater estuary or move back into fresh water for overwintering). Mike then hopes to again characterize the overwintering microhabitats of individuals in the Upper Salmon River.

Jason Hallett gave a talk at was the International Council for the Exploration of the Sea (ICES) Study Group on Anguillid Eels in Saline Waters from September 3-5, 2009 in Gothenburg, Sweden. He also participated in the joint ICES/European Inland Fisheries Advisory Commission (EIFAC) Working Group on Eels from September 6-12. This working group focused on fisheries reporting, stock assessment and management of European eel stocks. This year there was a small delegation from Canada (3 individuals out of 34 participants), so there was a small component on the current status of the American eel.

Erinn Ipsen headed north for the summer as a research assistant in Churchill, Manitoba. In Churchill, she had the chance to further familiarize herself with marine science (and the ever present polar bear!) on the coast of Hudson Bay. Now she is starting research on the Musquash estuary, NB for her MSc project.

Recent Happenings - Culp Lab

Joseph, Donald, David A., Jessica O. and Alexa from CRI Fredericton attended the TERA (Trait-based Ecological Risk Assessment) workshop in Burlington, Sept 7 to 11th, 2009. Thirty, international researchers attended the workshop to develop and discuss the application of trait based approaches. A fun time was had by all! We had beautiful weather, good food and terrific discussions!

Alexa is participating in Envirothon, Canada's largest highschool science competition, again this year with our first workshop at Mactaquac Provincial Park September 22nd, 2009. Persons interested in participating in Envirothon are invited to get in touch with Alexa at their convenience!

Alexa is attending the ATW workshop in La Malbaie, Charlevoix, QC, September 27 to 30th, 2009. If anyone needs a ride, let me know!

Joseph Culp and Eric Luiker from Environment Canada and CRI Fredericton and Daryl Halliwell from Environment Canada’s Saskatoon office spent a week in mid-July collecting algae, invertebrates and water samples from 27 Arctic streams in Sirmilik National Park on Baffin Island. The research is part of the International Polar Year project Arctic BioNet which is a research network focused on increasing our understanding of Arctic freshwater biodiversity along a latitudinal gradient ranging from the eastern Canadian High Arctic to the subarctic.
Dea Chute and Allison Ritcey near a large glacier in the McCornick River valley, northern Labrador.

Allison Ritcey from CRI Fredericton returned to northern Labrador this summer to complete field sampling for her MSc thesis on the ecosystem structure and function of streams in the Torngat Mountains National Park. The aims of her research are to establish patterns in algal biomass production and organic matter decomposition, and to investigate how these processes relate to food chain length, complexity and diversity. Establishing ecological patterns will provide the basic understanding of these systems that is needed to predict climate change impacts that may affect Arctic charr and will also aid development of the Park’s freshwater biomonitoring program. This summer Allison had lots of fun working with Inuit students and Elders and enjoyed running a student workshop on stream ecology alongside Dea Chute from the Curry lab!

• Research is currently being conducted by Dr. Culp and Dr. AdamYates (Environment Canada, Burlington) to evaluate how community structure and function and ecosystem processes in tributaries of the Red river affects the transmission, retention and removal of nutrients. Tributary watersheds of the Red river are heavily used for agriculture and have been hypothesized to be important sources of nutrient input to Lake Winnipeg. Ecological monitoring tools will be developed to allow evaluation of the effectiveness of current and future management activities. Water chemistry, instream metabolism, benthic macroinvertebrates as well as stream and riparian plants are all being sampled in 2009 and 2010 along the longitudinal profiles of two southern Manitoba tributaries to the Red River and a study of approximately 20 Manitoba subwatersheds is being initiated in 2010 to determine how differences in the extent and type of nutrient releasing human activity relate to ecological condition (i.e., instream metabolism, benthic macroinvertebrate community structure, N15/N14 ratios of invertebrates and plants). Together these two research components will enhance understanding of instream nutrient dynamics in the tributary streams of the Red River Basin in support of the Lake Winnipeg Basin Initiative (LWBI) objective of addressing and managing non-point source contributions of nutrients in the watershed and ultimately to the lake.

Recent Happenings - Curry Lab

Dr. Allen Curry taught BIOL 4373 Coral Reef Fishes of Cuba with Drs. Coqui Aguilar Betancourt and Gaspar Gonzalez from the University of Havana (and are also CRI Associates).

The course brings UNB students together with students from the University of Havana for a week long course with snorkeling in reefs around Cuba. This year was a super success, with the main drama being an encounter of a Portuguese Man O' War by two of the UNB participants - both escaped with some nice welts and a great story to tell.

The instructors left the students to snorkeling once in a while to dive down a bit deeper and explore Cuba underwater.

Recent Happenings - Kidd Lab

The Kidd Lab recently attended the 37th annual Aquatic Toxicity Workshop in La Malbaie, Charlevoix, Quebec. Karen Kidd gave her presentation, entitled “Is the birth control pill an effective form of contraception for wild fishes?” to a conference room so full there was standing room only.

Leanne Baker presented a poster on her Ph.D work for several hours to dozens, if not more, interested and question filled individuals. The remainder of the lab kept themselves busy by attending presentations, and volunteering within the ATW by co-chairing platform sessions, judging posters, etc.

At the Aquatic Toxicity Workshop, Karen Kidd won the highly-coveted Baby Beluga Award for having the funniest title. The award is on display in her office in Saint John.

Heidi Swanson
went to the 6th International Charr Symposium in Stirling, Scotland, in June.

Karen Kidd
gave two plenary presentations at workshops in Toronto and Colorado and two invited presentations in Copenhagen and Quebec City.

Meredith Clayden and Katharina Fischer made four trips to Kejimkujik National Park in Nova Scotia this summer and fall. They battled the black flies in May and collected aquatic invertebrates, sediments and water chemistry samples through the warm and sunny months of summer. There was lots of sunshine and the water was a beautiful temperature. In September they bundled up and collected fish (yellow perch, brown bullhead, white perch, golden shiner, banded killifish, and white sucker). The fish were co-operative, the fall colours were gorgeous, and there were some fun wildlife sightings; overall it was a great field season.

Everyone had a successful and safe field season in Pinawa, Manitoba! The Winnipeg River was quite high for most of the summer, but we managed to get most of the work done anyway. Sweet success!!

Cam Barth is on the road to completing his PhD degree and spent this past summer writing up his dissertation.

Cheryl Klassen has recently wrapped up a third summer of data collection for her PhD degree which included both laboratory studies focusing on the causes of growth rate variability among larval lake sturgeon, as well as, field studies to determine the success of past lake sturgeon stocking events.

Craig McDougall finished his first field season of an MSc degree monitoring the movements of 99 lake sturgeon he implanted with acoustic transmitters. He also collected tissue samples from approximately 180 adult lake sturgeon for a genetics study. It was a busy, but successful, season for Craig!

Recent Happenings - St. Hilaire Lab

Many members of André St. Hilaire's lab participated in the 62nd National conference of the Canadian Waters Resources Association, held in Québec City last June. Valérie Ouellet and André St. Hilaire were members of the organizing committee. The conference was a huge success, with nearly 400 participants.

André St-Hilair
e and Anik Daigle are participating in a project dealing with thermal refugia in salmonid rivers, along with other CRI Fellows (R. Cunjak and A. Curry). Thermographs were deployed in three rivers (Ouellet, Ste-Marguerite and Miramichi) during summer 2009. André is still looking for a student for this project.

Dae Jeong is a post-doctoral fellow working on the development of a statistical downscaling method in order to generate multisite climate information. He has two papers accepted about work he did in South Korea and another paper has been submitted with André and other collaborators.

Anik Daigle is still collaborating with André but for the fall semester she is teaching physics at the François-Xavier Garneau College in Québec City. We hope to see her back for the next semester. She recently published a paper dealing with modelling of the onset of the water temperature annual cycle in rivers and has submitted a paper co-authored by D. Baird and D. Peters on water temperature modelling in the OKanagan Valley.

Update on current students:

• Sandra Proulx-McInnis (MSc candidate) is presently in the field, collecting her data and enjoying surprises that come with working on fen environment! Sandra has designed a lysimeter that is able to take evapotranspiration measurements peatlands.
• Hélène Higgins (MSc candidate) is measuring turbidity at two sites on the Saint John River and waiting for the fall flood. She hopes that her instruments will not travel down to the Bay of Fundy and that they will still be waiting for her when she come back to look after them. She is wrapping up her first paper dealing with the characterization of suspended sediment regime on the Kenebecasis River.
• Mohammed Aziz Es-Salhi (MSc candidate)monitored suspended sediment concentrations downstream of two harvested peat bogs in New Brunswick for two years. He is now analyzing results and will be able to verify the efficiency of settling ponds for holding peat sediments. He is finishing his master and writing his first paper for publication.
• Dan Beveridge (MSc candidate) competed his thesis dealing with the selection of hydrologic indices that best characterise the flow regime of prairie rivers. He has completed his thesis and he will be defending soon.
• Valérie Ouellet (PhD Candidate) is back in the office after a summer in the field studying a lovely fish: carps! Now that she does not smell like dead fish any more, she will begin water temperature simulations for St. Lawrence River. Her first paper, dealing with statistical analysis of extreme water temperature and water levels associated with the 2001 fish mortality has been accepted for publication.
• Simon Tardif (PhD Candidate) compared the degree of wetness of various peatlands on the La Grand River drainage basin. He is finishing his thesis. Two papers are in preparation and one has been already accepted.

Well the CRI cap is making its way around the globe! This is Dr. Jonathan Grey of the University of London in London England - wearing the cap in Africa while hanging out with a few close friends behind him (well too close for my comfort!) - he adds that one should "not try this at home"... he is safe and sound though as he sent us the pic :). Thanks Jon!

May/June 2009 edition

The May 2009 edition has come a bit late - time is flying by already - I made the move to Manitoba for the summer and somehow lost track of time in there!

Thanks for all of the many sCRIbes out there that took the time to put their lab's info together. Most people are busy out there in the field these days - so I am hoping that the September '09 issue is full of updates on research projects and lots and lots of great pictures to share.

Her presentation was entitled “Transients in the north: interactions of migratory fish, climate change, and contaminant accumulation in coastal Arctic lakes.” Congratulations Heidi!!!

The first week of May we started our whole pond experiments at CFB Gagetown. Twenty-four ponds have been split into two and we are treating one side with glyphosate either on its own or in combination with N and P to examine the effects of these stressors on wetland communities. Leanne Baker (PhD student) has been in the field most days sampling the aquatic invertebrates and feeding the terrestrial invertebrates!

Recent Happenings - MacLatchy Lab

Kelly Lippert Roberts (research coordinator in the MacLatchy Lab at Laurier) was married in March to Stewart Roberts. She also completed her BEd at University of Western Ontario in April.

Recent Happenings - Peake Lab

Most of the Peake research crew headed out to Pinawa, Manitoba to wrestle sturgeon for the summer field season. However, they seem to catch more weeds than fish.

Bill Tibble recently headed out to Newfoundland to acoustically tag brook trout. Mr. Nice guy wanted to feel what the fishes were feeling and tried to do surgery on himself. It required 4 stitches.

Cheryl Klassen successfully completed her PhD candidacy exam this spring and received a 2-year NSERC Post Graduate Scholarship.

Claire Hrenchuk was successful in receiving an NSERC Industrial Scholarship for her MSc project.

Recent Happenings - UPEI group

The Atlantic Coastal and Estuarine Science Society (ACCESS) Workshop: “Estuaries: A Threatened Resource” was held at UPEI in Charlottetown, PEI on May 13th-15th. The workshop was well attended by CRI folks and several CRI graduate students gave wonderful presentations and posters on their research. Thank-you to the Co-ordinator Mike van den Heuvel and the Organising Committee: Gary Bugden, Simon Courtenay, Martha Jones, Pedro Quijon, Jeff Davidson, Andy Trivett, Kevin Teather, Megan Finley, Christina Pater, Cindy Crane, Mark Hanson, Lori Edwards, and Jon Stackpool as well as the numerous volunteers that helped make this workshop a success.

Allison Schein (MSc candidate co-supervised by Mike van den Heuvel and Simon Courtenay) won 1st place in the Student Platform competition at the ACCESS Workshop for her presentation titled: Effects of agriculturally-derived nitrate and increased sea lettuce growth on the estuarine food web structure of Prince Edward Island. Congratulations Allison!

Monitoring PEI Amphibians for Disease

A collaborative research project led by Natacha Hogan and Kevin Teather (CRI Associate Fellows) and Maria Forzan (wildlife pathologist, Atlantic Veterinary College) will assess the presence and distribution of a chytrid fungus as a potential threat to the health of amphibians on PEI. This fungus and resulting disease outbreaks have been linked to the decline or extinction of up to 200 amphibian species worldwide. Results of this project will be used to foster awareness among the public and special interest groups regarding disease status of amphibians and make recommendations to appropriate authorities, offices and local groups for implementing measures to effectively impede the introduction and/or spread of the fungus. Summer fieldwork is underway and involves swabbing frogs at sites from across PEI for diagnostic testing for the fungus. This project is funded by the PEI Wildlife Conservation Fund and a UPEI Major Research Grant.
