Seminars of the Institute of Hydrobiology BC CAS in 2021


Exceptionally on Wednesday 29. 9. 2021, 13.00 (1 pm.)

Genome evolution – from ostracods towards fish (and back)

Radka Symonová (new coming head of zooplankton group)

The talk will be focused on the current research in the field of genome evolution in freshwater (in)vertebrates utilizing cytogenomics. Polyploidization as the key factor in animal genome evolution will be emphasized together with compositional genome evolution, where transposons play the lead role. One of the goals will be an effort to identify any potential intercepts between cytogenomics of ribosomal genes and current topics in fish biology at the HBU/IoH in monitoring and protection of freshwater biodiversity.




Matthias Pilecky (Danube University Krems) The lubricant of the neurophysiological engine - the potential of n3 PUFA to change food web dynamics

In recent decades, much of the conceptual thinking in trophic ecology has been guided by theories of nutrient limitation and the flow of elements, such as carbon and nitrogen, within and among ecosystems.

More recently, ecologists have also turned their attention to examining the value of specific dietary nutrients, in particular polyunsaturated fatty acids (PUFA), among which the omega-3 PUFA especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) play a central role as essential components of neuronal cell membranes in many organisms.

I will present a new neuro-ecological approach stemming from the biochemical (mechanistic) and physiological (function) role of DHA in neuronal cell membranes, in particular in conjunction with G-protein coupled receptors (GPCR) and its potential implications for (aquatic) food web dynamics. In this context, I will also present stable isotope methods revealing metabolic adaptations to the dietary provision of EPA and DHA.
