NEWS FROM THE LAB

January 2016

·         We are accepting applications for new graduate students (see opportunities link) to work on gamete ecology. Students with a background in sperm biology are particularly encouraged to apply.

·         Craig was the chief organizer for the 69th Canadian Conference for Fisheries Research, which ran Jan 7-9. Our lab was also an author on 6 presentations.

·         Paper by former MSc student Corey Clarke has been published by the journal Animal Conservation. It is titled “Lifelong and carry-over effects of early captive exposure in Atlantic salmon”, and was done in Fundy National Park.

·         Craig was interviewed live on the NTV Evening Newshour about what we have learned since the collapse of the northern cod stocks 25 years ago

 

December 2015

·         Our work on sperm ecology has been heavily featured in a review published this month by Reinhardt, Dobler and Abbott (Annual Review of Ecology, Evolution and Systematics 46:435-459). In many ways it is similar conceptually to the NSERC Discovery Grant proposal (Gamete ecology in variable environments) that Craig currently has in review.

·         Craig submitted a new 3-year grant proposal to the Atlantic Salmon Conservation Foundation, entitled “Salmon gametes as a source for research, restocking and public engagement”

 

November 2015

·         Craig gave an invited seminar at the University of Manitoba on Nov 6 called “Gamete plasticity under environmental perturbation”

·         Former postdoc Laura Weir and Craig submitted a paper called “Subtle natural water chemistry induces sperm plasticity in a stream spawning fish” for review

·         Craig was interviewed twice by the CBC to discuss the effects of breeding between farmed and wild salmon, and factors influencing recruitment in capelin

 

October 2015

·         Welcome to Tanner Stein, who joined the group as a new MUCEP student

·         Brendan, Craig and Ian Fleming submitted a paper to Reviews in Fish Biology and Fisheries called ”In search of a cultured fish phenotype: a systematic review, meta-analysis and vote counting analysis”

·         Craig gave an invited public lecture for Nature NL on Oct 15 titled “Weird sex: the unusual morphology, behaviour and gametes of capelin”

 

September 2015

·         Paper by Wringe, Fleming and Purchase entitled “The spawning success of cultured and wild male Atlantic cod does not differ during paired contests” has been published in the Marine Ecology Progress Series.

·         Paper by Brendan entitled “Rapid morphological divergence of cultured Atlantic cod of the northwest Atlantic from their source population” has been published in Aquaculture Environment Interactions

·         Craig gave an invited talk entitled “The future of salmon in our rivers” to the AGM of the Northeast Avalon Atlantic Coastal Action Program.

·         Craig has been asked to speak about salmon ecology at a Nature Conservancy of Canada event in spring 2016

 

August 2015

·         Grant entitled “Impacts of crude oil and dispersants on capelin reproductive performance” has been funded by the National Contaminants Advisory Group of DFO. Work will being in summer 2016.

 

July 2015

·         Craig gave public Q&A sessions on capelin reproduction for Nature NL.

·         Paper by Beirão, Purchase, Wringe, & Fleming entitled “Inter-population ovarian fluid variation differentially modulates sperm motility in Atlantic cod” has been published by the Journal of Fish Biology.

 

June 2015

·         Heather presented a paper titled “Investigations of hatch and emergence time, size and growth rates of young of the year charr among fjord rivers in northern Labrador, Canada” to the 8th International Charr Symposium in Tromso, Norway

·         Paper by former MSc student Lucas Warner entitled “Seasonal variation in estuarine habitat use by native Atlantic salmon and invasive brown trout in southeast Newfoundland” has been published in Northeastern Naturalist
