Temperature influences outcomes of an environmentally acquired symbiosis.

ABSTRACT: Microbial symbioses are essential for many animals, but their outcomes are often context dependent. For example, rising temperatures can disrupt symbioses by eliminating thermally sensitive symbionts. The temperature tolerance of a symbiont may therefore limit the temperature range of its host, but switching to a more thermally tolerant partner could expand this range. Eastern leaf footed bugs (Leptoglossus phyllopus) depend on symbiotic Caballeronia bacteria which they must acquire from the environment early in development. Could this result in intergenerational partner switching that improves host outcomes under changing conditions? As a first step towards answering this question, we tested the hypothesis that host outcomes in this symbiosis vary among symbiont strains in a temperature-d
