Figure 3 in Experimental induction of resins as a tool to understand variability in ambers

Figure 3. Experimental Agathis australis examples: (a–b) branch treatment in which three upper branches were removed to mimic noncatastrophic damage; (c–d) burn treatment in which each tree was burned on one side creating a burn 6 cm in length along the trunk to mimic a wild fire burning at a low level; (a) day 1 of branch treatment; (b) final day of branch treatment with less viscous light yellow resin visible; (c) day 1 of the burn treatment with small resin beads forming; (d) final day of burn treatment with viscous exudation.
