- ... We examined the use of dendroecological techniques for detecting past defoliations caused by Ormiscodes amphimone Fabricius (Saturniidae) in Nothofagus pumilio (Poepp. et Endl.) Krasser forests in northwestern Patagonia. We evaluated the suitability of the conifer Austrocedrus chilensis (D. Don) Pic. Serm. et Bizarri as a nonhost climate control for reconstructing Ormiscodes outbreaks on N. pumili ...

- ... False rings (FRs) are a tree-ring anomaly that can be used to better understand tree growth and potentially reconstruct past climatic events. The main objective of this study was to explore the association between FRs and climate, especially drought occurrence. Sampling was conducted in Nopiming Provincial Park. Wood cores were extracted from jack pine (Pinus banksiana Lamb.) in five stands and fr ...
