Dr. Elisabetta Pizzul is researcher of Ecology (Bio/07) at the Life Science Department of the Trieste University. Born in Gorizia on July 13, 1964, she graduated at the Trieste University in 1990. She began the service as researcher by the Faculty of Mathematical, Physical and Natural Sciences in July 1995 and she was confirmed in her role in October 1998.

She was the chief in many projects regarding ecological analyses in lotic environments in the Friuli Venezia Giulia. Her studies have focused the distribution of fish species, the composition of fish communities, and the safeguard of species listed in European Directives (such as Salmo marmoratus and Thymallus aeliani); she led studies regarding morphological analysis of lotic ecosystems and their fish communities in the context of hydrological and environmental monitoring plans in relation to the problem of water diversion for hydropower purposes and she led  studies about the application of biotic indices in lotic environments, in agreement with the European Directive 2000/60/EC. In this context, in 2009 she began a collaboration with ARPA Friuli Venezia Giulia, in order to apply the Index of the Ecological Status of Fish Communities (ISECI) in sites included in the Regional Water Protection Plan (PRTA).

In the last years, the scientific activities have focused on characterization of allochthonous species in Friuli Venezia Giulia (Silurus glanis), taxonomy of pike populations (genus Esox), reproductive biology Salmo marmoratus, definition of distribution areas for Barbus balcanicus and Gobio benacensis in the Isonzo River basin, ecology and distribution of transitional water species (Aphanius fasciatus, Knipowitschia panizzae, Pomatoschistus marmoratus and Pomatoschistus canestrinii). Freshwater macrobenthic invertebrates have been studied as bioindicators and in relation to the organic matter decomposition within temporary wetland (Isola della Cona), riverine systems (Isonzo River Mouth) and karstic lentic environments (Doberdò Lake). Moreover, energy density of freshwater macrobenthic invertebrates have been studied in lotic and lentic systems.

A collaboration with the Experimental Zooprofilactic Institute of Piedmont, Liguria and Valle d'Aosta has begun in 2017 for ecological analyses in lentic alpine and subalpine environments. Since 2018, a collaboration with the Regional Authority of Friuli Venezia Giulia has started in order to produce a map of the expected fish communities on regional scale. Finally, Dr Elisabetta Pizzul is the coordinator of the brown trout eradication plan in the Val Rosandra-Dolina Glinščice Natural Reserve.

She was the president of the Italian Freshwater Ichthyologists Association between 2014 and 2018.

The scientific activities are carried out individually or through collaborations and concern: 1) the application of biotic indices in agreement with the European Directive 2000/60/EC; 2) the study of biological and ecological aspects of freshwater fish species and the study of structures and dynamics of fish communities; 3) analyses on the macrobenthic invertebrates in relation to the important role they play within trophic webs, in decomposition processes of the organic matter and in the energy transfer through the trophic levels in freshwater ecosystems; in this context, it is of particular interest the analysis of the energy densities of the organisms and the studies on the decomposition of the organic matter.
