Growth and productivity of New Zealand kauri (Agathis australis (D.Don.) Lindl.) in planted forests [PDF]

, 2009
Background: The establishment of even-aged planted stands of New Zealand kauri (Agathis australis (D.Don) Lindl.) for timber has been constrained by a lack of quantitative information on productivity and rotation length on which forest management and ...

Drought avoidance and vulnerability in the Australian Araucariaceae [PDF]

Tree Physiology, 2015
The Araucariaceae is an iconic tree family. Once globally important, the Araucariaceae declined dramatically over the Cenozoic period. Increasing aridity is thought to be responsible for extinction and range contraction of Araucariaceae in Australia, yet little is known about how these trees respond to water stress.

Differential seedling survival of early‐planted, late‐successional trees: Results from three forest restoration experiments

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
Successful forest restoration starts early: Across three restored sites, late‐successional trees (n = 1840) established well when planted at the same time as pioneers. A 2‐m spacing maximized survival, revealing facilitation–competition trade‐offs, with outcomes also shaped by species identity and microhabitat.

Biochemical and morphological changes during the growth kinetics of Araucaria angustifolia suspension cultures

Brazilian Archives of Biology and Technology, 2010
Embryogenic cultures of Araucaria angustifolia were established in a BM liquid medium supplemented with 2 µM 2,4-dichlorophenoxyacetic acid, 1 µM 6-benzylaminopurine and 1 µM kinetin (BM2) and in a BM medium free of growth regulators (BM0).

Paleobotany reframes the fiery debate on Australia's rainforest edges. [PDF]

New Phytol
Summary The tall eucalypt forests (TEFs) of the Australian tropics are often portrayed as threatened by ‘invasive’ neighboring rainforests, requiring ‘protective’ burning. This framing overlooks that Australian rainforests have suffered twice the historical losses of TEFs and ignores the ecological and paleobiological significance of rainforest margins.
