Evolution of trophic transmission in parasites: why add intermediate hosts?
Although multihost complex life cycles (CLCs) are common in several distantly related groups of parasites, their evolution remains poorly understood. In this article, we argue that under particular circumstances, adding a second host to a single-host life cycle is likely to enhance transmission (i.e., reaching the target host). For instance, in several situations, the propagules of a parasite e...
متن کاملThe evolution of trophic transmission.
Parasite increased trophic transmission (PITT) is one of the more fascinating tales of parasite evolution. The implications of this go beyond cocktail party anecdotes and science fiction plots as the phenomenon is pervasive and likely to be ecologically and evolutionarily important. Although the subject has already received substantial review, Kevin Lafferty here focuses on evolutionary aspects...
متن کاملTrophic transmission of parasites and host behavior modification.
Thomas et al. (2005) provide a wide-ranging and insightful review of issues surrounding the evolution and ecology of parasite manipulation of host behavior. To support their goal seeking future directions I offer three comments. Firstly, several very different types of interactions are combined under the vague label “parasite”. This obscures important differences with respect to host behavior m...
متن کاملDisparate rates of molecular evolution in cospeciating hosts and parasites.
DNA sequences for the gene encoding mitochondrial cytochrome oxidase I in a group of rodents (pocket gophers) and their ectoparasites (chewing lice) provide evidence for cospeciation and reveal different rates of molecular evolution in the hosts and their parasites. The overall rate of nucleotide substitution (both silent and replacement changes) is approximately three times higher in lice, and...
