Unlike most desert-dwelling animals, Cataglyphis ants do not attempt to escape the heat;
rather, they apply their impressive heat tolerance to avoid competitors and predators. This …

One major advantage of sexual reproduction over asexual reproduction is its promotion of
genetic variation, although it reduces the genetic contribution to offspring. Queens of social …

Over the last decade, genetic studies on social insects have revealed a remarkable diversity
of unusual reproductive strategies, such as male clonality, female clonality, and social …

Genetic diversity acts as a reservoir for potential adaptations, yet selection tends to reduce
this diversity over generations. However, sexually antagonistic selection (SAS) may promote …

In eusocial insects, worker polymorphism is shaped by several factors, including colony size,
queen mating frequency, and the timing of queen-worker differentiation during larval …

Cataglyphis desert ants display unique variation in their breeding systems, making this
genus a particularly interesting model to study the evolution of derived reproductive traits in …

Thelytokous parthenogenesis is the production of females from unfertilized eggs. In this
review we categorize the known thelytokous eusocial Hymenopterans (mostly ants) by their …

We report a remarkable pattern of incongruence between nuclear and mitochondrial
variations in a social insect, the desert ant Cataglyphis hispanica. This species reproduces …

Sperm competition is a pervasive evolutionary force that shapes sperm traits to maximize
fertilization success. Indeed, it has been shown to increase sperm production in both …

Recently, a unique case of hybridogenesis at a social level was reported in local
populations of the desert ants Cataglyphis. Queens mate with males originating from a …
