The evolution of eusociality is one of the major transitions in evolution, but the underlying
genomic changes are unknown. We compared the genomes of 10 bee species that vary in …

Background The social life of animals depends on communication between individuals.
Recent studies in Drosophila melanogaster demonstrate that various behaviors are influenced …

Most theories used to explain the evolution of eusociality rest upon two key assumptions:
mutations affecting the phenotype of sterile workers evolve by positive selection if the resulting …

The process of domestication often brings about profound changes in levels of genetic variation
in animals and plants. The honey bee, Apis mellifera, has been managed by humans for …

Chemical communication mediates social interactions in insects [1]. For the fruit fly, D.
melanogaster, the chemical display is a key fitness trait because it leads to mating. An exchange …

The rise of insect societies, marked by the formation of reproductive and sterile castes, represents
a major unsolved mystery in evolution. Across several independent origins of sociality, …

Nutrition is known to interact with genotype in human metabolic syndromes, obesity, and
diabetes, and also in Drosophila metabolism. Plasticity in metabolic responses, such as …

Two distinct developmentally related behaviour patterns can be identified in third-instar
larvae of Drosophila melanogaster, ‘foraging’ behaviour and ‘wandering’, a pre-pupation …

The littoral zone is important in lake ecosystems. It affects physical, chemical, and biological
processes of the whole lake. We first describe patterns in the shoreline lengths of a lake …

Female behavior changes profoundly after mating. In Drosophila, the mechanisms underlying
the long-term changes led by seminal products have been extensively studied. However, …
