NEWS FROM THE LAB
· Anna has submitted paper on predictive models for salmon incubation as a function of temperature. Work was funded by Atlantic Salmon Conservation Foundation.
· Craig spent 7 days in a remote site of Prince William Sound Alaska, working with Peter Westley (UAF) on pink salmon reproduction
· We put a big effort into work on post-mating cryptic female choice in capelin with Trevor Pitcher (U Windsor) and Jon Evans (U Western Australia)
· Also collected spawning capelin for collaborative work with a University of Alaska Fairbanks student.
· Craig and Anna presented research on developmental timing of Atlantic salmon embryos during the Canadian Society of Zoologist meeting
· Heather’s first paper from her PhD has been accepted in Evolutionary Ecology Research.
· Collaborative work with a conservation angling group (SAEN) on the technique use of instream salmon incubators has been published in the North American Journal of Fisheries Management. This was funded by the Atlantic Salmon Conservation Foundation, and is titled “Performance of instream Jordan-Scotty salmon egg incubators under different installation and siltation conditions”. https://onlinelibrary.wiley.com/doi/abs/10.1002/nafm.10052
· Paper on capelin embryo development to varying salinities has been published by CJFAS http://www.nrcresearchpress.com/doi/10.1139/cjfas-2017-0058#.WvRcN38h2Uk
· Received news that NSERC has awarded a collaborate equipment grant with Yolanda Wiersma and Carissa Brown for a new field truck.
· Welcome to Tyler Lantiegne, who joins the lab as a new MSc student in May. Tyler is from, and has been trained to date in Alaska. He will be working on cryptic female choice over sperm competition in hybridizing salmonids.
· Welcome to Madison Philipp, who joins the lab as a new MSc student in May. Madison is from Illinois and did her undergraduate degree at Dalhousie in Nova Scotia. She will be working on among-male variation in sperm ecology.
· Steven, Heather and Craig attended an interesting WWF workshop on fish habitat restoration on March 1.
· Craig was an invited expert at the DFO salmon assessment meeting on Feb 28, and for the capelin assessment meeting on March 7.
· A new project has been approved that will spread our research on gamete ecology to a new system in Alaska. Craig and former MUN student Peter Westley will instigate this in August 2018.
· Paper on very unique capelin sperm has been published in Ecology & Evolution http://onlinelibrary.wiley.com/doi/10.1002/ece3.3783/full
· Craig gave a seminar Jan 31, at the Marine Institute School of Fisheries, called “Quirky sex on the beach: Newly discovered perils of capelin reproduction”
· Work with colleagues in Manitoba on chemical signatures of capelin otoliths has been published
· First paper from our oil contaminants research on fish gametes has been submitted for review. “Chemically-dispersed oil and dispersant affects sperm fertilizing ability, but not sperm swimming behaviour in capelin (Mallotus villosus)”.
· Steven and Heather both presented at a public form on local salmonid research on Dec 13
· Developing salmon embryos from one of our November hybridization experiments are nearly the eyed stage, and will soon be preserved to figure out who their daddy is (microsatellites).
· We had a team of 9 staff working on research projects related to hybridization between brown trout and Atlantic salmon through early November
· We were involved in the restocking of Atlantic salmon into Rennie’s River. Several members of the lab were leaders of various components and 42 volunteer days were involved from community members.
· Craig, Anna and Mohammad spent 10 days at the Experimental Lakes Area in NW Ontario, working on a senescence project with lake trout
· Paper on the first occurrence of dealfish in Canada has been accepted in the Canadian Field Naturalist
· Craig spent two weeks in the UK and presented sperm research at the 14th Biology of Spermatozoa meeting in Bakewell England, and gave research seminars at the University of Stirling and University of Glasgow.
