Hamaguchi, Kinomura and colleagues describe an ant species that lacks workers and males and consists exclusively of queens.

The vast majority of Hymenopterans determine sex by haplodiploidy, in which males and females develop from haploid unfertilized and diploid fertilized eggs, respectively. At the molecular level, the m...

Mona et al. report a complex supergene system in the ant Myrmecina graminicola characterized by three alleles determining both the number of queens in a colony (monogyne vs. polygyne) and the presence...

BRCA1 occurs on one of two major haplotypes in populations of European and Asian ancestry that show signs of selection and functional differences. Near-maximal linkage disequilibrium associated with t...

The genome of the Atlas blue butterfly contains ten times more chromosomes than most butterflies, and more than any other known diploid animal. Wright et al. show that this extraordinary karyotype is ...

A new major version of ggplot2 has been released on CRAN. Find out what is new here.

Ant queens of one species clone ants of another to create hybrid workers that do their bidding.

Widespread species often experience vastly different environmental conditions across their range. In species with polymorphic traits under strong genetic control, we can investigate how environmental ...

Abstract. Ants exhibit many complex social organization strategies. One particularly elaborate strategy is supercoloniality, in which a colony consists of

Author summary The remarkable and seemingly inconsequential variation in genome size across species has long been an enigma in evolutionary biology. Calling this viewpoint into question, correlations ...

Standing in a clearing surrounded by black spruce and birch, I raise my binoculars after spotting a quick flash of movement high up in the foliage.

Abstract. Genetic elements encoded in nuclear DNA determine the sex of an individual in many animals. In certain bivalve lineages that possess doubly uniparenta
