Resource allocation, water relations and crown architecture examined at the tree and stand-level in northern conifers
DownloadFall 2013
Variation in quantity of light has driven plants to employ many strategies in order to persist in high and low light. It is also a primary driver of lower branch mortality and crown recession. Fine roots and leaves are complimentary tissues representing belowground and aboveground resource...

Seasonal photosynthetic activity in evergreen conifer leaves monitored with spectral reflectance
DownloadSpring 2014
Annual trends of the Photochemical Reflectance Index (PRI) and pigment content in evergreen conifer leaves were monitored over two years from 2011 to 2013. During the second year, chlorophyll fluorescence and gas exchange were included to examine the spring recovery of photosynthesis. All the...

Bunya pine (Araucaria bidwillii Hooker) produces large seeds that consist of a massive megagametophyte that surrounds an embryo 25-30 mm long and 3-5 mm in diameter. The seeds germinate on the soil surface, but elongation of the cotyledonary tube pushes the hypocotyl, with its associated plumule...
