Inherited microorganisms that manipulate the reproduction of their host are a common
feature in arthropod biology. Although research initially concentrated on why these …

Symbiotic bacteria are important in animal hosts, but have been largely overlooked as they
have proved difficult to culture in the laboratory. Approaches such as comparative genomics …

Recent decades have witnessed an explosion of theoretical and empirical studies of sex
allocation, transforming how we understand the allocation of resources to male and female …

The Wolbachia endosymbionts encompass a large group of intracellular bacteria of
biomedical and veterinary relevance, closely related to Anaplasma, Ehrlichia, and …

Several lineages of symbiotic bacteria in insects selfishly manipulate host reproduction to
spread in a population, often by distorting host sex ratios. Spiroplasma poulsonii, is a helical …

The past years have revealed that inherited bacterial endosymbionts are important sources
of evolutionary novelty for their eukaryotic hosts. In this review we discuss a fundamental …

Species are fundamental units of comparison in biology. The newly discovered importance
and ubiquity of host-associated microorganisms are now stimulating work on the roles that …

Most species of insect, and many other plants and animals, carry maternally heritable
microorganisms—viruses, bacteria, unicellular eukaryotes, and fungi that pass from a female …

Although heritable microorganisms are increasingly recognized as widespread in insects,
no systematic screens for such symbionts have been conducted in Drosophila species (the …

Wolbachia are the most widespread maternally-transmitted bacteria in the animal kingdom.
Their global spread in arthropods and varied impacts on animal physiology, evolution, and …
