Hidden partners: Symbiodolus bacteria found in various insect orders

Max Planck researchers describe a new endosymbiont that is widespread in insects and whose ecological role needs to be further investigated more

Odors are encoded in rings in the brain of migratory locusts

Researchers in Jena show that chemical information is represented completely differently in the brains of these insects than in other insects or vertebrates more

Oxidant pollutant ozone removes mating barriers between fly species

Elevated ozone levels increase the occurrence of mostly sterile hybrids between different species of the genus Drosophila more

New habitats affect plant defense

Populations of ribwort plantain outside their original range are just as well defended as native populations, and in some cases even better more

Silkmoths: Different olfactory worlds of females and males

Female moths primarily use their sense of smell to find the best host plants on which to lay their eggs, with the deterrent effect of caterpillar feces playing an important role more

Nature is inventive - the same substance is produced differently by plants

The production of special plant defense compounds has evolved independently in distantly related plant families more

Tracking down the formation of cardenolides in plants

Researchers identify the first enzymatic step in the biosynthesis of these plant steroids important in the medical treatment of heart disease more

Division of labor affects the risk of infection

Ants that leave the nest to forage are more likely to be infected by parasites than their nestmates who take care of the brood more

It all depends on the genetic diversity

Natural tobacco mutants impaired in their defenses produce more offspring in years of low herbivore pressure and thus persist in plant populations more
