Dorota Olga Paczesniak

I’m studying the evolution and maintenance of reproductive modes a New Zealand freshwater snail Potamopyrgus antipodarum, where in many populations sexual and asexual snails coexist.

In my PhD, I’m addressing the following questions:

• How many asexual lineages actually realize the predicted ‘two-fold reproductive advantage’ over their sexual counterparts?
• What is the variation in fitness among asexual lineages?
• Is fitness of clones habitat dependent?
• How do new asexual lineages originate?
• Do spatial and temporal population dynamics differ between co-existing sexual and asexual populations?

short CV:

2009 – present - PhD student in evolutionary ecology at ETH Zurich and Eawag, The Swiss Federal Institute of Aquatic Science and Technology in Dübendorf, Switzerland.

I’m supervised by Jukka Jokela (ETH Zurich) and Maurine Neiman (The University of Iowa).

2007 – 2008 - Research assistant in SexAsex EU Marie Curie Research and Training Network studying interactions between sexual and asexual reproduction in freshwater ostracod Eucypris virens.

I worked with Roger Butlin and Dunja Lamatch at the University of Sheffield, UK and Jukka Jokela at Eawag,The Swiss Federal Institute of Aquatic Science and Technology in Dübendorf, Switzerland.

2005 – 2007 - Masters student in biology at Jagiellonian University in Krakow, Poland.

I did my thesis under the supervision of Ryszard Korona. I was studying how epistasis between deleterious mutations affects fitness in yeast under various environmental stressors.

2001 – 2005 - Undergraduate studies in biology and geography at Jagiellonian University in Krakow, Poland.
