Data from: Maternity of emergency queens in the cape honey bee, Apis mellifera capensis

Madeleine Beekman, Ben Oldroyd, Michael Allsopp, Theresa Wossler & Michael Holmes
During reproductive swarming, some workers of the Cape honey bee, Apis mellifera capensis, lay eggs in queen cells, many of which are reared to maturity. However, it is unknown if workers are able to lay in queen cells immediately after queen loss during an episode of emergency queen rearing. In this study we experimentally de-queened colonies and determined the maternity of larvae and pupae that were reared as queens. This allowed us to determine how...

Data from: A quantitative study of worker reproduction in queenright colonies of the Cape honey bee Apis mellifera capensis

Madeleine Beekman, Ben Oldroyd, Michael Allsopp, Alex Jordan & Julianne Lim
Reproduction by workers is rare in honey bee colonies that have an active queen. By not producing their own offspring and preventing other workers from producing theirs, workers are thought to increase their inclusive fitness due to their higher average relatedness towards queen-produced male offspring compared with worker-produced male offspring. But there is one exception. Workers of the Cape honey bee Apis mellifera capensis are able to produce diploid female offspring via thelytokous parthenogenesis and...

Data from: Evolutionarily accelerated invasions: the rate of dispersal evolves upwards during the range advance of cane toads

Benjamin L Phillips, Greg P Brown & Richard Shine
Human activities are changing habitats and climates, and causing species' ranges to shift. Range expansion brings into play a set of powerful evolutionary forces at the expanding range edge that act to increase dispersal rates. One likely consequence of these forces is accelerating rates of range advance due to evolved increases in dispersal on the range edge. In northern Australia, cane toads have increased their rate of spread five-fold in the last 70 years. Our...
