Antibiotics affect migratory restlessness orientation

The role of microbiome in shaping animal’s behavior is well established. Accordingly, the use antibiotics may have profound effects on behavior, which are seldom examined. Recently, symbiotic magnetic-sensing hypothesis has been forwarded as a mechanistic explanation for phenomenon animal magnetoreception. It suggests relationship between magnetotactic bacteria (MTB) and navigating host. To establish research protocol future behavioral studies, we examined effect widely used antibiotic substance migratory restlessness orientation bacteria. Using migrating Eurasian reed warblers, show that contrast to control group, treatment caused lack clear directionality an Emlen funnel experiment. group showed significant increase directional variance. This behaviors associated with magnetic sensing might be considered preliminary experimental support hypothesis. Further, lay could implemented experiments aiming prove or refute
