DESCRIPTION:Dr Luca Carraro\, Postdoctoral researcher\, Department of Aqua
 tic Ecology\, EAWAG\nAbstract:\nFreshwater environments are particularly r
 ich in biodiversity\, hosting about 10% of the known animal species\, desp
 ite occupying only 2% of the global water surface. However\, global change
  is posing serious threats to biodiversity\, with effects on freshwater en
 vironments that are reportedly more severe than is the case for terrestria
 l or marine habitats. This calls for the development of adequate tools for
  freshwater biodiversity assessment at high spatiotemporal resolution\, wh
 ich must be based on an appropriate description of riverine landscapes\, t
 heir connectivity structure\, and the hydrological drivers that affect loc
 al abiotic conditions and dispersal processes. In this talk\, I will prese
 nt a suite of modelling approaches to study spatial ecohydrological proces
 ses in river networks\, and specifically: i) The generation of virtual ana
 logues of river networks (so-called Optimal Channel Networks) that share t
 he same topological and scaling features of real rivers\; ii) The relation
 ship between riverine connectivity patterns and metrics defining stability
  and persistence of a metapopulation\; iii) A meta-ecosystem perspective o
 n the spatial distribution of riverine communities\; iv) A hydrology-based
  model for transport of environmental DNA (eDNA\, i.e.\, molecular traces 
 of organisms sampled from stream water) that allows assessment of highly r
 esolved riverine biodiversity patterns. All of these approaches are linked
  by a substantial unity of methodologies\, which ultimately shows the cruc
 ial role exerted by hydrological processes in shaping ecological communiti
 es in river networks.\n\nShort biography:\nAfter a B.Sc. and M.Sc. in Civi
 l and Hydraulic Engineering at the University of Padua (Italy)\, Luca Carr
 aro obtained a Ph.D. in Civil and Environmental Engineering at EPFL in 201
 8. There\, he worked at the interface of hydrology\, ecology and epidemiol
 ogy\, especially focusing on the epidemiological modelling of a disease (p
 roliferative kidney disease) lethal to salmonid fish. Subsequently\, he mo
 ved to Eawag (Dübendorf\, Switzerland) for a postdoctoral fellowship at t
 he Department of Aquatic Ecology (jointly funded by the University of Zuri
 ch)\, where he has been mostly focusing on the development of environmenta
 l DNA transport models in rivers. As of July 2022\, he will start an SNF A
 mbizione fellowship at the University of Zurich\, where he will expand his
  research coupling hydrological and ecological models to enhance the asses
 sment of riverine biodiversity patterns.
