Trophic 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 کاملThe bigger, the better? Volume measurements of parasites and hosts: Parasitic barnacles (Cirripedia, Rhizocephala) and their decapod hosts
Rhizocephala, a group of parasitic castrators of other crustaceans, shows remarkable morphological adaptations to their lifestyle. The adult female parasite consists of a body that can be differentiated into two distinct regions: a sac-like structure containing the reproductive organs (the externa), and a trophic, root like system situated inside the hosts body (the interna). Parasitism results...
متن کاملThe many roads to parasitism: a tale of convergence.
Parasitic organisms account for a large portion of living species. They have arisen on multiple independent occasions in many phyla, and thus encompass a huge biological diversity. This review uses several lines of evidence to argue that this vast diversity can be reduced to a few evolutionary end points that transcend phylogenetic boundaries. These represent peaks in the adaptive landscape rea...
متن کاملIntroduced and Native Populations of a Marine Parasitic Castrator: Variation in Prevalence of the Rhizocephalan Loxothylacus Panopaei in Xanthid Crabs
Patterns of prevalence and host specificity of the parasitic castrator, Loxothylacus panopaei, in a region of parasite introduction (Chesapeake Bay, Maryland-Virginia) were compared to those within its native geographic range (Indian River Lagoon, Florida). Prevalence in five species of xanthid crabs was measured at several spatial and temporal scales along the east coast of North America. The ...
متن کاملTrophic interactions among three elasmobranch species coexisting in the Oman Sea: implications for resource partitioning
In this study, trophic interactions were studied among three elasmobranches including Iago omanensis, Rhinobatos punctifer and Torpedo sinuspersici coexisting in the depth ranging from 50 to 100 meters in the Oman Sea (Sistan and Balochistan waters). A total of 238 specimens were collected using industrial bottom trawlers of ‘FERDOWS’ during spring and summer,2014 and their stomach contents wer...
