Host relatedness and landscape connectivity shape pathogen spread in the puma a large secretive carnivore

摘要

a Bayesian time-scaled phylogenetic tree for FIVpco subtype CO found in both the wildland–urban interface (WUI) and unbounded (UB) regions. b Bayesian time-scaled phylogenetic tree for FIVpco subtype WY which was only found in the UB. I–III represent the different clades identified using tree structure analysis69. Virus branch colours are based on population assignment posterior values from our FIVpco subtype CO discrete trait analysis. c Host relatedness cladogram constructed using singular value decomposition (SVD) quartets37 based on over 12,000 SNPs from 130 individual puma across both study areas. The grey shaded box encompasses related individuals with phylogenetically similar FIVpco isolates. Virus symbols (from panels a and b) are coloured based on viral lineage membership. This colour matches the puma infected with that isolate (puma silhouettes c) and the lines connecting each isolate to each host in the tanglegram. Tips without virus symbols indicate that there was no matching host genomic data for this FIVpco isolate. Branch colours indicate which region each individual puma and matching virus was sampled from (WUI or UB).
