... programming Inflammation Maternal effect Rodent Thrifty gene hypothesis Parental effects occur when the phenotype or the environment experienced by one or both parents influences the phenotype of the offspring independently of the effects of direct genetic transmission ( Marshall and Uller, 2007...

...Carmi Korine; Boris R. Krasnov; Irina S. Khokhlova; Berry Pinshow SUMMARY We examined feeding performance of the flea Xenopsylla ramesis on three different hosts: its natural, granivorous, rodent host, Sundevall’s jird ( Meriones crassus ); the frugivorous Egyptian fruit bat ( Rousettus aegyptiacus...

... O 2 max ) during forced exercise were similar to those of other small rodents; basal metabolic rate was below allometric predictions. At all tested speeds, voluntary running had a lower energy cost than forced treadmill running, due primarily to a higher zero-speed intercept of the speed- versus...

... production in Xenopsylla conformis and Xenopsylla ramesis when exploiting two rodent hosts, Meriones crassus and Gerbillus dasyurus . The number of blood meals taken by a flea prior to first oviposition was similar in both flea species but was dependent on flea density and differed significantly between...

... the severity of the immune responses depends on parasite load. In the enclosure animals, immune response to antigen from the unfamiliar flea Synosternus cleopatrae pyramidis did not differ from those to antigens from the familiar fleas. In contrast,laboratory rodents demonstrated no difference in the immune...

Here, we examine the phenotypic flexibility of water flux rate, urine osmolality and the expression of kidney aquaporins (AQP; or water channels) in free-ranging Octodon degus , a South American desert-dwelling rodent, through an integrative study at cellular, systemic and organismal...
