From: Phylogeographic analysis reveals association of tick-borne pathogen, Anaplasma marginale, MSP1a sequences with ecological traits affecting tick vector performance

Figure 2

Associations between A. marginale MSP1a R1 repeat sequences and ecoregion clusters, plotted along the values of the first two axes derived from Principal Components Analysis on normalized difference vegetation index (NDVI) time series. Figure plots the 80% confidence ellipses of the annual mean normalized difference vegetation index (NDVI) and the seasonal variation of NDVI for each ecoregion cluster, as well as the plot of the isolates in the NDVI envelope. Each letter displays the mean position of the records for that strain. Unique sequences for each ecoregion are displayed in plain type. Sequences recorded in more than one ecoregion cluster are displayed in italic bold.
