The "Kill the Winner" hypothesis relates to Lotka-Volterra equations. Viral lysis, which disproportionately targets the "winners" of marine ecosystems.. The "Kill the Winner" hypothesis (KtW) is an ecological model of population growth involving prokaryotes, viruses and protozoans that links trophic interactions to biogeochemistry. [1]
A marine virus is more likely to infect cooccurring organisms, those that live in the same region the virus lives in. [130] Therefore, biogeography is an important factor in a virion's ability to infect.
Viruses are now considered to play key roles in marine ecosystems by controlling microbial community dynamics, host metabolic status, and biogeochemical cycling via lysis of hosts. [41] [42] [44] [45] A giant marine virus CroV infects and causes the death by lysis of the marine zooflagellate Cafeteria roenbergensis. [46]
Alison Murray is an American microbial ecologist and Antarctic researcher, best known for studying the diversity, ecology and biogeography of Antarctic marine plankton dynamics of the plankton over the annual cycle; and her work demonstrating the existence of microbial life within an ice-sealed Antarctic lake (Lake Vida).

Viral phylodynamics is the study of how epidemiological, immunological, and evolutionary processes act and potentially interact to shape viral phylogenies. [1] Since the term was coined in 2004, research on viral phylodynamics has focused on transmission dynamics in an effort to shed light on how these dynamics impact viral genetic variation.
Viral dynamics is a field of applied mathematics concerned with describing the progression of viral infections within a host organism. [1] It employs a family of mathematical models that describe changes over time in the populations of cells targeted by the virus and the viral load. These equations may also track competition between different ...

For example, the modelling of infectious disease dynamics is a popular research topic in mathematics, notably in applied mathematics or mathematical biology. While most modelling efforts in mathematics have focused on elucidating the dynamics of spread of infectious diseases at an epidemiological scale (person-to-person), there is also ...
