Figure 1. Genealogy of DCV isolates.

Unrooted maximum likelihood tree showing all virus samples identified in our dataset (see File S1), including host identity (ID), host species, last known origin of the sample, and duration of laboratory maintenance in our stock collection until the time of RNA extraction. Host lines “never in contact” are wild caught lines which have never been in physical contact with lab stocks; all other lines are lab stocks. Host ID contains information about whether strains were extracted from multiply infected samples (L: low peaks; H: high peaks; see Materials and Methods and File S2).
