Resource predictability and host specificity in fleas: the effect of host body mass.
Ecological specialization is hypothesized to result from the exploitation of predictable resource bases. For parasitic organisms, one prediction is that parasites of large-bodied host species, which tend to be long-lived, should specialize on these hosts, whereas parasites of small host species, which represent more ephemeral and less predictable resources, should become generalists. We tested ...
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 کاملDigesting blood of an auxiliary host in fleas: effect of phylogenetic distance from a principal host.
Fleas are haematophagous ectoparasites that exhibit varying degrees of host specificity. Flea abundance is highest on principal hosts and lower on auxiliary hosts but may vary greatly among auxiliary hosts. We investigated the feeding and energy expenditure for digestion in two flea species Parapulex chephrenis and Xenopsylla ramesis on a principal host (Acomys cahirinus and Meriones crassus, r...
متن کاملThe evolution of host specificity in dove body lice.
OBJECTIVE Conventional wisdom suggests that parasites evolve increased host specialization over time. Host specificity, which describes the number of host species parasitized, is one aspect of host specialization. Recent studies of vertebrate parasites indicate that highly host-specific parasite lineages are not, in fact, evolutionary dead ends; host generalists can evolve from host specialists...
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...
