Host specificity in parasitic plants—perspectives from mistletoes
Host specificity has been investigated for centuries in mistletoes, viruses, insects, parasitoids, lice and flukes, yet it is poorly understood. Reviewing the numerous studies on mistletoe host specificity may contribute to our understanding of these plants and put into context the dynamics at work in root parasitic plants and animal parasites. The mechanisms that determine host specificity in ...
متن کاملBeta-specificity: the turnover of host species in space and another way to measure host specificity.
Host specificity is often measured as the number of host species used by a parasite, or as their phylogenetic diversity; both of these measures ignore the larger scale component of host use by parasites. A parasite may exploit very few host species in one locality but these hosts may be substituted for completely different species elsewhere; in contrast, another parasite may exploit many host s...
متن کاملEvolution of host specificity in fleas: is it directional and irreversible?
Evolutionary trends in the evolution of host specificity have been the focus of much discussion but little rigorous empirical testing. On the one hand, specialization is often presumed to lead irreversibly into evolutionary dead ends and little diversification; this would mean that generalists might evolve into specialists, but not vice versa. On the other hand, low host specificity may limit t...
متن کاملHost Specificity of Cuscuta reflexa Roxb. in the Manas Biosphere Reserve, Indo-Burma Hotspot
The dodder plant Cuscuta reflexa Roxb. is an angiospermic leafless parasitic plant belonging to the family Cuscutaceae is abundantly found colonizing certain plant species in the premises of Manas Biosphere Reserve (MBR) and nearby area. Ten (10) angiospermic host plants in total of the above parasite were recognized. Based on the field inspection most of the numbers of patches were recorded in...
متن کاملConcepts in Insect Host-Plant Selection Behavior and Their Application to Host Specificity Testing
Testing the host specificity of potential agents is an important part of biocontrol methodology. An understanding of the behavioral processes involved in selection of a host plant can be used to improve the accuracy of host specificity testing by biocontrol practitioners and others interested in predicting field host use. These behavioral processes include the sequential nature of host selectio...
