Viral ecology is a rapidly progressing area of research, as molecular methods have improved significantly for targeted research on specific populations and whole communities. To interpret and synthesize global viral diversity and distribution, it is feasible to assess whether macroecology concepts can apply to marine viruses. We review how viral and host life history and physical properties can influence viral distribution in light of biogeography and metacommunity ecology paradigms. We highlight analytical approaches that can be applied to emerging global data sets and meta-analyses to identify individual taxa with global influence and drivers of emergent properties that influence microbial community structure by drawing on examples across the spectrum of viral taxa, from RNA to ssDNA and dsDNA viruses.
