2.2 | Study Area and Sampling
For the selection of population groups and individuals of J.
chilensis to be sampled, we considered three parameters: i.populations with more than 50 individuals; ii. a sampling scheme
that covers the entire species’ geographical range; and iii. the
exclusion of specimens belonging to plantations. Sampling was then
conducted in six population groups, whose population sizes correspond to
95.98% of the total species abundance (González et al. 2017), ordered
from north to south: (a) Culimo (CUL), (b) Petorca (PET), (c) Ocoa
(OCO), (d) Viña del Mar / Valparaíso (VAV), (e) Cocalán (COC), and (f)
Candelaria (CAN) (Figure 1, Table 1).
