August 2016. David Reznick prepares to begin his Guggenheim Fellowship.

David Reznick will use his Guggenheim Fellowship to spend a year at Oxford University. He aspires to learn something of Integrated Population Models and mixed effects modeling during his time there. We wish him the best of luck for his time abroad!

June 10, 2016. Martin Turcotte gets a new position.

Congratulations to former FIBR graduate student Martin Turcotte on becoming a newly minted  assistant professor at the University of Pittsburgh. All the best to him in his new environs!

June 10, 2016. Another wave of FIBR alumni enter graduate school.

Several former interns have accepted offers to begin graduate school in the upcoming academic year. Kathryn Chenard, former intern and field manager, will join Renée Duckworth's lab at the University of Arizona. Greg Larsen, another former intern and field manager, will begin at Duke University in David Johnston's lab, working on large marine mammals. Greg will bring with him a wealth of experience and an NSF Graduate Research Fellowship. Tomas Potter, former intern, lab manager and experimental ace, has accepted the offer of the Oxford University Doctoral Traineeship Program. While he has not chosen a major professor or study system, he may very well return to Trinidad for his doctoral research. Meanwhile, Toby Hector will begin exploring the Southern Hemisphere as a PhD student in Matthew Hall's lab at Monash University, Melbourne, Australia. Good luck to all in their new academic adventures!

December 28, 2015. News from the FIBR family tree

Former FIBR intern (2011-2012) extraordinaire Jennifer Hoey has had a successful start to her PhD at Rutgers University. She has been applying genetic techniques to understand population structure, dispersal and connectivity in summer flounder. In the future, she may expand these themes to examine how fishing pressure and climate have influenced adaptation in this species. Best of luck moving forward, Jennifer!

September 21, 2015.  New FIBR papers!

Two new FIBR papers have been published, one in the journal Oikos and another in Freshwater Biology. Please click on the Publications page to view them!

September 17, 2015.  Where are they now? News on FIBR alumni

        Matthew Walsh, a former graduate student affiliated with FIBR, is now an assistant professor at the University of Texas, Arlington.  He has just received a grant from NSF to exploit the long-term data set amassed by a LTER project in Wisconsin to study the evolution of microcrustacea in Wisconsin lakes. There are traces of responses to climate change and other anthropogenic influences on the environment evident in the phenotypes of samples archived over the past 30 years.  Matt will extract information from these archived samples and combine it with laboratory experiments that characterize genetic divergence among the extant populations.  You can hear an interview of Matt that was featured on NPR at this link: http://www.wpr.org/biologist-gets-national-science-grant-study-environmental-change-wisconsin-lakes

September 2, 2015.  Nature paper press releases

A paper published on 2 September 2015 in Nature by Ghalambor and colleagues has been featured in several press releases:

Featured press release entry:

Evolutionary biology: How guppy fish adapt to new environments
 
DOI: 10.1038/nature15256
 
An evolutionary study involving guppy fish populations provides insights into how organisms adapt to environmental change, reports a paper published in Nature this week.
 
Changes in the environment drive organisms to alter their characteristics, and this can occur through evolutionary changes across generations (genetic adaptation), as well as through plastic changes in gene expression within a generation (phenotypic plasticity). Although it is known that phenotypic plasticity may influence evolutionary change by altering the distribution of phenotypes upon which natural selection acts, it is not currently clear whether it facilitates or hinders genetic adaptation. 
 
Cameron Ghalambor and colleagues transplant wild Trinidadian guppy fish (Poecilia reticulata) from a stream with predatory pike fish into two predator-free streams, and compare brain gene expression patterns between the original and the transplanted populations after three to four generations, as well as with a native predator-free population. They find that when the phenotype varies in the same way as is favoured by natural selection (adaptive plasticity), the genes that gave rise to the phenotype tend not to evolve in response to selection. Conversely, when the phenotype varies in the opposite way (non-adaptive plasticity), those genes evolve rapidly.
 
“A question that needs to be addressed in future studies is whether results from gene expression analyses can be extended and generalized to macroscopic traits that have more direct ecological relevance,” says Juha Merilä in an accompanying News & Views article.
