1. coextermination

   the simultaneous extinction of two or more species (especially when one is dependent on the other) coextinction of a species is the loss of a species as a consequence of the extinction of another. the term was originally used in the context of the extinction of parasitic insects following the loss of their specific hosts. the term is now used to describe the subsequent loss of any interacting species, including predators with their prey, and specialist herbivores with their food source. coextinction is especially common when a keystone species goes extinct. the most often cited example is that of the extinct passenger pigeon and its parasitic bird lice columbicola extinctus and campanulotes defectus. recently, c. extinctus was rediscovered on the band-tailed pigeon, and c. defectus was found to be a likely case of misidentification of the existing campanulotes flavus. however, even though the passenger pigeon lice story has a happy ending, coextinctions of other parasites, even on the passenger pigeon, may have occurred. several louse species—such as rallicola extinctus, a huia parasite - probably became extinct together with their hosts. in a 2004 paper in science, ecologist lian pin koh and colleagues discuss coextinction, stating "species coextinction is a manifestation of the interconnectedness of organisms in complex ecosystems. the loss of species through coextinction represents the loss of irreplaceable evolutionary and coevolutionary history. in view of the global extinction crisis, it is imperative that coextinction be the focus of future research to understand the intricate processes of species extinctions. while coextinction may not be the most important cause of species extinctions, it is certainly an insidious one."

   for instance, the extinction of host fish causes the extinction of all parasites located on it.
