“…Such growth of CS is clearly associated with technological development (Nature Publishing Group, 2015), which not only facilitated the communication with all participants but also reduced the costs of equipment needed for the collection of the data and broadened the variety of tasks that can be performed (Blaney, Jones, Philippe, & Pocock, 2016). Public engagement now ranges from generating research questions to the collection and scientific analysis of data and to communicating the research results back to the public (Bela et al, 2016;Shirk et al, 2012). Citizen science has been successfully implemented in various scientific fields, not only in biology, ecology and conservation (e.g., Brooks, 2013;Fore, Paulsen, & O'Laughlin, 2001;Howard, Aschen, & Davis, 2010;Penrose & Call, 1995), but also in biochemistry (Lee et al, 2014), astronomy (Lintott et al, 2008), comparative genetics (Singh et al, 2017) and physics (Barr, Kalderon, & Haas, 2017;Sørensen et al, 2016).…”
