Table 1 Sample sizes of koalas in each time point analysed by PCA and average maximum, minimum temperatures (°C) of the month prior to sampling and the average rainfall (mm) of the preceding 3 months prior to each time point across time points A, B and C in the LP and D and E in the SHSWS.

From: A novel multi-variate immunological approach, reveals immune variation associated with environmental conditions, and co-infection in the koala (Phascolarctos cinereus)
