Host 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 کاملHost–parasite–herbivore Interactions: Implications of Host Cyanogenesis
To examine the mediation of host–predator interaction by a parasite, we studied the three-level interactions among a host plant, a root hemiparasitic plant, and their common predator, a generalist snail herbivore. The host species, Trifolium repens, is able to synthesize cyanogenic glucosides that have a significant role in plant herbivore resistance. Some T. repens populations are polymorphic ...
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 کاملNatal Host Plants Can Alter Herbivore Competition
Interspecific competition between herbivores is widely recognized as an important determinant of community structure. Although researchers have identified a number of factors capable of altering competitive interactions, few studies have addressed the influence of neighboring plant species. If adaptation to/ epigenetic effects of an herbivore's natal host plant alter its performance on other ho...
متن کاملMutualism favours higher host specificity than does antagonism in plant-herbivore interaction.
Coevolved mutualisms often exhibit high levels of partner specificity. Obligate pollination mutualisms, such as the fig-fig wasp and yucca-yucca moth systems, represent remarkable examples of such highly species-specific associations; however, the evolutionary processes underlying these patterns are poorly understood. The prevailing hypothesis suggests that the high degree of specificity in pol...
