The general relevance of Blochmannia for the ant host is apparent from fostering experiments showing that colonies of C. floridanus suffer serious fitness losses when workers are cured of infection with Blochmannia.
Thomas Barnardo began his foster experiment in 1887 by dispatching 320 orphan boys of "good conduct and character" from the East End slums of London to board out with "homely folk" in rural villages who were paid five shillings a week to bring up their charges.
Compared to a classical cross-foster experiment, where C57 and DBA mice would have exchanged mothers, our approach reveals two interesting new aspects.
To separate environmental and genetic contributions to covariance between sire size and larval traits, we compared sire offspring regressions for biological and foster sires in the cross-fostering experiment (Fig. 2).
Foster experimented with "condensed" doping under a doctor's supervision, and also trained by cycling the Tour de France route with professionals.
In classical cross-fostering experiments (exchanging pups between two strains), not only the quality of the maternal environment is manipulated, but also the genetic background of the mother.
To facilitate comparisons with other studies, we first used the standard method for analysing cross-foster experiments, which is based on using offspring values alone [ 49].
Designed to foster crossdisciplinary experiments in the arts, the Tang is finished in stone, metal and concrete, and is surrounded by a circle of white pines.
New ways to use connectivity to deliver benefits to people and enterprises of all kinds," he noted, going on to list various examples of how it has worked with others to foster IoT experiments.
A cross-fostering experiment was conducted in which groups of Mamber and Damascus kids were reared indoors by biological mothers or by does of the reciprocal breed.
We tested whether mouse songs are learned, by examining the relative role of rearing environment in a cross-fostering experiment.
