Special seminar on phenotypic plasticity and evolution in plants

Hello All,

A candidate for a post-doctoral position in my lab is visiting Sheffield this Friday and Saturday and will give a 30 minute seminar on his work on phenotypic plasticity and evolution in Arabidopsis at 4pm this Friday, July 4th in the Common Room. All are welcome and encouraged to attend. We will head to the pub then at 5pm.

cheers, Patrik

single cell sequencing

Hello All,

If anyone has any information or experience with DNA sequencing from single cells (e.g., individual sperm), can you please get in touch with me about this?

thanks,

Patrik (p.nosil@sheffield.ac.uk)

Japanese stickleback talk TODAY by Mark

as indicated in the previous post, so just a reminder, noon in B52 Mark Rivenet, who attended the genomics workshop, will give a 30 minute talk on the curious Japanese stickleback – the only ones to exhibit intrinsic hybrid inviability and some odd courtship behavior. All are welcome. cheers, Patrik

Talk in APS on evolution of Japanese stickleback

Hello All,

A postdoctoral fellow who is visiting APS for the course next week will give a talk on Thursday about his work on the evolution of Japanese stickleback. He is also aiming to apply for a Marie Curie fellowship to work between Japan and my lab on this system.

Time: noon-1pm, Date: March 21st, Place: B52

title and abstract below, all are welcome, cheers,

Ecological speciation and adaptive radiation in Japanese sticklebacks

Mark Ravinet
Queen’s University Belfast, UK; National Institute of Genetics, Mishima Japan

When species colonize new environments, they often undergo remarkable
diversification, occupying unexploited niches and evolving remarkable
adaptive phenotypic variation. Adaptive radiations driven by divergent
natural selection between habitats can therefore play a major role in
the evolution of biodiversity. Yet why is it that some species are
more prone to adaptive radiation than others? Over the last 10 years,
the stickleback species complex has become an evolutionary
‘supermodel’ for the study of rapid phenotypic adaptation and
speciation. Two highly divergent Japanese stickleback species occur
across the Japanese archipelago. The Japan Sea and Pacific Ocean forms
are unique in that they are the only known example of an anadromous
species pair and furthermore they experience near-complete
reproductive isolation. Curiously, only one lineage, the Pacific
Ocean, is able to colonize freshwater and therefore diversify
phenotypically. The Japanese stickleback system therefore provides an
excellent opportunity to study the role that ecological divergence has
played in shaping both speciation and the extent of adaptive
radiation.

My talk next week

Hello, yes, my talk is next week and Julia is correct that there will be stuff relating to using genome wide SNP data. However, I decided to make my talk much more general than this, because many people will be new to our work. Thus, I will give more of a ‘Nosil lab overview’ talk where I will introduce the people in the lab, the goals of the ERC funded project, the lab methods we use, and the analytical methods we use. So, it will be more of a ‘getting to know us’ talk than one on scientific results, but I imagine this will be best for a general audience and will act as a springboard for future discussion. This is a long way of saying you might come even if you don’t care about SNPs….

have a good weekend,

ps. if anyone is ever going bouldering, let me know, I go all the time…

Happy to join the Molecular Ecology Group

Hello everyone,

I am new here (Patrik Nosil here…), just arrived this week, but very excited to be here. I look forward to getting to know everyone. I was also thinking I could give an informal seminar sometime soon about my lab, the ERC project I am here to implement, and especially of interest to some people might be the methods (both lab and bioinformatic/statistical) that we have used successfully for RAD-tags (well, at least the point there are papers submitted or in revision). Perhaps I could talk at one of the Tuesday lab meetings or something.

cheers, Patrik
