Viruses are ubiquitous in the sea. They are the most abundant group of biological entities and represent the largest pool of genetic diversity in the marine ecosystem. Viruses are the active members of marine ecological system. They affect the nutrient cycling and the energy flow through lysing their hosts, which transfer particle organic carbon into dissolved organic carbon, and form the “viral loop”. Viral abundance, diversity and distribution are important parameters in marine viral ecology. But, as static parameters, they can not meet demands of viral ecological studies of dynamic processes. It is necessary to investigate dynamic parameters in the viral ecological processes. In this paper, major dynamic parameters, including contact rate, infection rate, burst size, host mortality caused by viruses, viral production and decay rate, and related techniques in ecological research of marine viruses in recent 20 years are reviewed.
