Development and characterization of polymorphic microsatellite markers for Conopholis americana (Orobanchaceae)

23 Apr 2012 - 1:52pm

Anuar RodriguesThis week we recognize the work of Ph.D. student Anuar Rodrigues from the Stefanović Lab.

Anuar’s paper recently appeared in American Journal of Botany. This paper develops new molecular resources for studying population genetic diversity in an obligate root parasite. Their initial screen shows that C. americana populations appear to be highly inbred. These markers will now be used to initiate a larger scale study of the population genetics and phylogeography of Conophilis.

Keep up the great work, Anuar!

Regulation of MAPK/ERK signaling and photic entrainment of the suprachiasmatic nucleus circadian clock by Raf kinase inhibitor protein

12 Apr 2012 - 2:26pm

This week we recognize the work of PhD student Pascale Bouchard-Cannon from the Cheng Lab.

Her paper was just published in The Journal of Neuroscience. In this paper Pascale and her collaborators identified the RKIP gene as a key regulator of light-induced MAPK signaling and entrainment of the suprachiasmatic nucleus circadian clock. This represents Pascale’s first paper as a PhD student at UTM, and an exciting one at that!

Congratulations, Pascale!

The utility of body size indices derived from optical plankton counter data for the characterization of marine zooplankton assemblages

26 Mar 2012 - 2:27pm

This week we celebrate the MSc research of Karla Krupica, who recently completed an MSc with Gary Sprules. This also represents an impressive hat-trick for the Sprules lab, who have had the last three Hot Student Papers!

Karla’s paper appeared in a recent edition of Continental Shelf Research.

In this paper, Karla and colleagues show how simple statistical indices derived from digital size data on marine zooplankton, collected with an automated Optical Plankton Counter, can be used to characterize temporal and spatial patterns in the structure of zooplankton communities on the Scotian Shelf off Nova Scotia. Karla is now a Biologist with the Ontario Ministry of Natural Resources in Lindsay.

Great job, Karla!

Effects of Bythotrephes longimanus (Crustacea, Cladocera) on the abundance, morphology, and prey community of Leptodora kindtii (Crustacea, Cladocera)

19 Mar 2012 - 2:29pm

Sophie FosterThis week we recognize the work of former PhD student Sophie Foster from the Sprules Lab and former EEB Post-Doc Angela Strecker.

Their paper recently appeared in Hydrobiologia. In this paper they demonstrate interesting indirect ecological effects of the invasive predatory invertebrate (Bythotrephes) on a related native predator (Leptodora); probably by changing the composition of the zooplankton community upon which both predators depend, Bythotrephes has induced morphological changes in Leptodora.

Energy acquisition and allocation patterns of lake whitefish (Coregonus clupeaformis) are modified when dreissenids are present

5 Mar 2012 - 2:30pm

This week we recognize the work of former Ph.D. student Mike Rennie from the Sprules Lab.

Mike’s paper was recently published in the Canadian Journal of Fisheries and Aquatic Sciences. His research demonstrates indirect ecological effects of invading dreissenid mussels on lake whitefish. The mussels have modified the prey base in a manner that increases the foraging activity and hence costs for whitefish, and this probably explains why individual growth rates of whitefish have declined in many invaded lakes.

Mike is currently working as a scientist with the Dept. of Fisheries and Oceans in Winnipeg. Congratulations, Mike!
