This book answers the question “What is it that viruses do?” by presenting three aspects
of viral ecology. The first aspect explains how viruses affect the population diversity
and energetics of their host communities. Perhaps the most notable example of this
concept is our understanding that primary production within ecosystems often depends
upon those viruses which serve as controllers of nutrient recycling, connecting the
aquatic and terrestrial realms in ways that can be assessed locally and globally.
The second aspect describes genetic partnerships which exist between hosts and their
viruses. These include processes termed endogeny and lysogeny by which the host carries
at least a partial genomic copy of the virus. Fluidity of these collective genomes
is expressed on an evolutionary time scale and the mutual life cycles which they produce
represent a forging of shared genomic fate that obligates partnership of the virus
and its host. The viral sequences represent a source of potential benefit as well
as potential peril for the host and can implement phenotypic changes in the host.
Hosts often use those changes as tools. As humans, the most notable example would
be that mammals rely upon temporary activation of their endogenous viral genes in
order to successfully develop a placenta. The third aspect is defending the health
of a host, which relies upon activity in two directions. Hosts often use their captured
viral genes to identify and subsequently direct battle against invading viruses. This
natural concept has been engineered for combating cancer, is useful for suppressing
the detrimental consequences of genetic diseases, and has been developed to create
targeted antiviral vaccines. But, the defense has to work in two directions and the
host can use other symbiotic microorganisms as protection against its viruses. This
book will appeal to a wide readership by providing a broad perspective of viral ecology,
and all scientists will find it helpful for gaining a view of fields beyond their
specialization
