In each case she introduced an intruder, in the form of a spider from the same colony.
Workers from the same colony sacrifice their own reproductive opportunities to boost that of a single queen or, occasionally, a small ruling council.
Only 40% of the time did they attempt to chase the intruder away, or bite it.Ms Grinsted then took another 40 spiders and swapped some of their broods (though always to a female from the same colony).
In contrast, the bacterial communities associated with L. pertusa varied among polyps from the same colony, as well as among distinct colonies and between seasons.
And the blueprints are an inherent part of the colony; when the colonies were split into groups, each group from the same colony erected strikingly similar "shelter tubes," the researchers report this month in Insectes Sociaux.
In experiment 1, both RJ and WJ came from the same colony as the experimental larvae.
At each time point, measurements of twenty individual cilia from the same colony of cells were made and averaged.
Our results confirmed that simultaneously radiotracked individuals from the same colony foraged together significantly more than expected by chance.
As shown below large variations in O2− production rates were found between corals fragments taken from the same colony, making the comparison between treatments difficult.
For all the experiments bumble bee foragers were collected from the same colony of B. terrestris, supplied by Bioplanet s.c.a., Cesena, Italy.
We profiled two independent cohorts of Flinders animals derived from the same colony six months apart, each cohort statistically powered to allow independent as well as combined analysis.
