Benefits and costs of hosting facultative symbionts in plant‐sucking insects: A meta‐analysis
Molecular Ecology, Volume 30, Issue 11, Page 2483-2494, June 2021., 2021 Abstract Many animals have evolved associations with symbiotic microbes that benefit the host through increased growth, lifespan, and survival. Some interactions are obligate (essential for survival) while others are facultative (usually beneficial but not essential). Not all individuals host all facultative symbionts in a population, and thus there is

Plant, Cell &Environment, Volume 42, Issue 12, Page 3293-3307, December 2019., 2019 Abstract Belowground (BG) herbivory can influence aboveground (AG) herbivore performance and food preference via changes in plant chemistry. Most evidence for this phenomenon derives from studies in herbaceous plants but studies in woody plants are scarce.
