Publication! Opalescent nudibranchs marching northwards.

Congrats particularly to Kathryn Milligan, Nola Sheets and Emily Merlo, who started this off as course project at Bamfield Marine Sciences Centre in the 2016 Marine Ecology class taught by Dr. Chris Neufeld and Tao Eastham.  We were able to show that there were two species of Hermissenda present in Barkley and Clayoquot Sounds on Vancouver Island.  One is supposed to be there,  while the other is supposed to be in southern California.  Telling them apart is fairly straight forward, when you know what to look for: northern Hermissenda crassicornis have white striped cerata (sticky up bits) while southern Hermissenda opalscens have white tips but no stripes on their cerata. With the help of Dr. Ángel Valdés and Ka’ala Estores-Pacheco as well as the Barcode of Life group, we confirmed the original  morphological data with genetic analyses.  The question now, of course is why?  Perhaps climate factors?  Other species were also found far further northwards than normal that year…

Range extension for the region of sympatry between the nudibranchs Hermissenda opalescens and Hermissenda crassicornis in the northeastern Pacific.

Congrats to WyethLab alumn, Jane Fletcher – accepted into an MSc program at the University of Calgary.

Jane will be studying novel ways to reduce methane gas production by cows, based on viral microbiome work.  That seems a far cry from the sea slug navigation behaviour she studied in the WyethLab.  But she has already been using some of the same analysis and data management tools learned with the slug work in her new lab.  A great example of how research can take you down unexpected paths.

Congrats! Ella Maltby just successfully defended he MSc thesis proposal!

Just 6 months into her program, Ella has developed an ambitious plan to study the impact of contaminants on lobster. Her fieldwork has already started, which meant some very early mornings on some local lobster boats recently. She got a moment to rest after the proposal defense, but then it was right back to work on some extra sampling decided on during the committee meeting.

almost the whole WyethLab

Here’s almost the whole crew – travel schedules didn’t mesh so we are unfortunately missing Katerina and Sophie, but otherwise we’re all in the line!  From left-to-right…

And missing are…

WyethLab, going with the flow

Presenting at CSZ in St. John’s

We’ve just wrapped up a great week at the annual meeting of the Canadian Society of Zoologists. Alex Young and Areej Alansari presented their snail research – on neural gene expression and navigation behaviour, respectively. Ella Maltby presented her work from the last couple years on ultraviolet light as an antifoulant. And Russell went in a new direction, sharing research on crow behaviour conducted by the 2015 and 2016 students in his 4th year Animal Behaviour course.

milestones, news, and more

Lots of congratulations to share…

Carmen Landry submitted the final version of her Honours thesis.

Amelia MacKenzie was awarded Holly E. Bartlett Memorial Bursary (in the StFX News)

Ella Maltby and Areej Alansari presented their MSc work in a split seminar to the Biology Department to widespread acclaim!

And RCW and Mar Wonham’s article on teaching the scientific method also was shared by StFX News (along with some nice comments from Carmen and others!)

Wyethlab at Student Research Day

Ella and Carmen

Unfortunately, I had to miss Student Research Day this year while travelling in Europe.  But the WyethLab was well represented!  Carmen Landry won the top award for oral presentations sharing her work on reference genes for qPCR in snails.  Although they didn’t compete for awards, I’m reliably informed that both Ella Maltby (poster) and Amelia MacKenzie (talk) did a great job with their presentations on antifouling research.

JEB Symposium & Dropping in on Dr. Daniel Jackson

Lymnaea juveniles used for in situs

I have just returned from a quick trip to Europe.  The first half was participating in Journal of Experimental Biology Symposium 2018: Linking brain and behaviour in animal navigation.  Spring time in the shadow of Mt Olympus in northern Greece was a great place to meet and discuss the forefront of navigation neuroethology.  And then the second half was quick visit to meet up with Alex (Wyethlab MSc student) and Dr. Daniel Jackson at University of Göttingen.  Alex is visiting Dan’s lab to learn in situ hybridization methods in the pond snail, Lymnaea.  Some good conversations with Dan – hopefully leading to further interesting collaborations in the future!
