Abstract Symbiosis can benefit hosts in numerous ways, but less is known about whether interactions with symbionts—the smaller species the relationship. To determine fitness impact of host association on symbionts likely mutualisms, we conducted a meta-analysis across 91 unique host-symbiont pairings under range spatial and temporal contexts. Specifically, assess consequences to symbiont when out symbiosis, as well symbiosis suboptimal or varying environments biological conditions (e.g., age). We find that some intracellular associated protists tend have greater stressful conditions. Symbionts plants animals did not exhibit this trend, suggesting multicellular are more robust perturbations. Symbiont also generally increased age. Lastly, show able proliferate in- outside cells than those found exclusively inside cells. The ability grow multiple locations may thus help thrive. discuss these patterns light host-driven factors, whereby exert influence over suit their own needs.
