TL;DR: Investigation of aphids for vulnerability of the aphid host to a hymenopteran parasitoid, Aphidius ervi, shows that infection confers resistance to parasitoids attack by causing high mortality of developing Parasitoid larvae.

TL;DR: In this paper, the authors examined the influence of abiotic and biotic factors on the gut bacterial communities of fish from different taxa, trophic levels and habitats, and found that fish harbor more specialized gut communities than previously recognized.

TL;DR: Findings reveal a role for heritable symbionts in the adaptation of aphids to their abiotic environments and add to an expanding body of knowledge on the adaptive significance of symbiosis.

TL;DR: Phylogenetic analyses of partial sequences of gyrB and recA are consistent with previous analyses limited to 16S rRNA gene sequences and yield improved confidence of the evolutionary relationships of these symbionts.

TL;DR: To explore the dynamics of secondary symbiont associations in aphids, bacteria infecting 15 species of macrosiphine aphids were characterized using DNA sequencing, diagnostic polymerase chain reaction (PCR), diagnostic restriction digests, phylogenetic analyses, and electron microscopy to examine aphids from nature and from laboratory colonies.
