Possible changes of the brown trout habitat suitability in the upper Po basin due to global change

C limatic simulation models predict an increase in temperature and extreme events occurrence. These changes are expected
to lead a sensible modification of the hydrological cycle with significant impacts on the ecological integrity of aquatic
ecosystems. Changes in temperature regime and in-stream habitat/microhabitat characteristics will also affect the natural
distribution of many aquatic species. Within this context it appears strategic to predict the effects of global change on
freshwater biodiversity and species distribution in order to propose adequate measures aimed at mitigating the impacts of
climate modification on natural systems. To this aim we carried out a simulation based on a chain of deterministic models
to predict the distribution of the brown trout in the upper Po River basin (North Italy). A 140-years long simulation, carried
out with a Regional climate model, is used to force a hydrological model simulating the hydrological cycle. The results of
hydrological simulation, in particular variations in temperature and discharge regimes, are then used to evidence the areas
where the target species is expected to occur. The results show how the complex proposed approach is able to reproduce, with a
good confidence, the current distribution of the brown trout. The projection for future years indicates a shift of the distribution
toward locations of the upper part of the basin, with a sensible decrease of the areas where the brown trout can survive,
reproduce and grow. This work also focuses on the potential application of the proposed approach to evaluate the effects of
climate changes on more complex ecological systems.
Biography
Annalina Lombardi has accomplished her PhD in April 2016. She gained scientific and research experience at CETEMPS, University of L'Aquila, Italy, where she
obtained several scholarships, aimed at specializing in numerical modeling, especially hydrological modeling. She has taken part in various European projects
regarding hydro-meteorological risk prevention and management. During her career at the CETEMPS, she obtained a Post-doc, and has learnt the usage of
atmospheric mesoscale models, weather and climate prediction, and the manipulation of a large number of data. At present days, she has collaborated in the
publication of two papers on two main journals.
