Research interests:

I am interested in ecology and evolution of planktonic animals and fish. The goal of my recent studies is focused on finding the optimal distribution of Daphnia in overlapping gradients of food and predation risk in the water column, and on assessing the role of zooplankton in "active transport" of nitrogen from subsurface layers to the depth. My future plans consider the effects of cyanotoxins and temperature on learning abilities of planktivorous fish.


Grant projects:

(2015-2017) Project leader – grant PRELUDIUM of National Science Centre (2014/13/N/NZ8/02462) on the vertical distribution of Daphnia as a result of optimizing decisions in the gradient of food concentration, temperature and predation risk.

(2014-2015) Project leader - grant ETIUDA of National Science Centre (2014/12/T/NZ8/00287) on the ideal free distribution (IFD) of Daphnia against gradients of food concentration, temperature and of individual risk of predation.

(2012-2015) Participation in research projects of prof. Z. M. Gliwicz (Grant 2011/03/B/N28/02093) on the patch exploitation and individual fitness in planktivorous fishes from temperate and tropical habitats: a global-warming perspective.

(2008-2012) Project leader – grant of Ministry of Science (N N304 067336) on the ideal free distribution (IFD) of Daphnia against gradients of food concentration and of individual risk of predation.
