Scientists examined the biological variations in pea aphids, insects that reproduce frequently enough to evolve before our eyes, by tracing the prevalence of their protective endosymbiont, ...

Only further study will resolve these issues. A better understanding of insect–symbiont biology will require not only mechanistic explorations of how the two parties interact, but also more cage and ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 106, No. 22 (Jun. 2, 2009), pp. 9063-9068 (6 pages) Eukaryotes engage in a multitude of beneficial and deleterious ...

Scientists have shed new light on how the cockroach organism works. They have shown why the German cockroach (Blatella germanica) eliminates excess nitrogen by excreting ammonia, in contrast to most ...

Researchers tested whether heat tolerance among 5 species of aphids varies with heat sensitivity of the species' endosymbionts, and found that heat exposure--37-38 °C for 3-4 hours--reduced survival ...

Cells in symbiotic partnership, nested one within the other and functioning like organelles, can borrow from their host’s genes to complete their own metabolic pathways. There are few relationships in ...

Evolution is unfolding in real time within many natural animal populations and researchers are now observing how this influences biodiversity in the field. In a newly published study in Molecular ...
