Genetic and environmental variation in wood properties of Acacia melanoxylon [PDF]

Annals of Forest Science, 2011
& Context Australian blackwood (Acacia melanoxylon), is a fast-growing, high-quality, appearance-grade timber species native to eastern Australia. Some of its key wood properties are percentage heartwood, heartwood colour, basic density, wood stiffness and green moisture content. Variation in these properties affects log value, processing and marketing.

Melanism in salamanders: effects of insularity, sex and size on dorsal colouration in Salamandra salamandra

Journal of Zoology, EarlyView.
In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...

Post‐fire vegetation shifts: Role of invasives and seedbanks in an Australian grassy woodland ecosystem

Journal of Ecology, Volume 114, Issue 4, April 2026.
Wildfire and invasive species interact in a south‐eastern Australian grassy woodland, with the soil seedbank introducing predominantly non‐native species into the extant vegetation after fire. This influx can temporarily increase ecosystem flammability and promote a grass–fire cycle.

TWO METHODS FOR TREE VOLUME ESTIMATION OF Acacia melanoxylon IN PORTUGAL

FLORESTA, 2011
AbstractTwo models were developed to evaluate total volume under and over-bark of Blackwood (Acacia melanoxylon R. Br.) stand trees. By variance analysis regarding volume with and without bark it was confirmed that trees age is responsible for 48 to 50% of its volumetric behaviour.
