"The aphid Pemphigus betae typically shows a complex life cycle, with annual alternation between cottonwood trees, where it forms leaf galls, and herbaceous plants, where it lives on roots. Distinct ph…"

"Buchnera only have 600 genes, compared to about 4,000 or 5,000 for E. coli ... This is a recurring pattern in the genomes of both bacterial symbionts and pathogens, but why do they get so small? ... w…"

"Life cycles that incorporate discrete, morphologically distnct phases predominate among animals."

"Among the many early revelations from molecular phylogenetic studies of bacteria was the recognition that the mycoplasmas represented an evolutionarily derived condition rather than a primitive one, a…"

"Symbioses are central in the evolution of complexity; have evolved many times and are critical to the lifestyles of many animals and plants and also to whole ecosystems, in which symbiotic organisms a…"

"Biogeographical and paleobotanical evidence suggests that the aphid subtribe Melaphidina has been associated with its sumac host plant since the early Eocene when these plants were continuously distri…"

"Heteroecy appears to be a consequence of the seasonal polymorphism of aphids, which causes some morphs to be more evolutionarily constrained than others in their abilities to acquire hosts. Some aphid…"

"The guts of honey bee workers contain a distinctive community of bacterial species. They are microaerophilic or anaerobic, and were not clearly deliniated by earlier studies relying on laboratory cult…"
