Invasiveness, ecological impacts and control of acacias in southwestern Europe – a review [PDF]
The most prolific acacias in southern Europe (Acacia dealbata, A. melanoxylon and A. longifolia) are rapidly spreading in its westernmost area: Portugal and NW Spain, where congeners with invasion potential are already established.

Acacia invasion triggers cascading effects above- and belowground in fragmented forests [PDF]
Invasive alien plants like Acacia species are key drivers of ecosystem change, with considerable effects on forest structure, nutrient cycling, and biodiversity. In the Mediterranean region, which is already vulnerable to challenges such as anthropogenic

La presencia de árboles en un ecosistema de pastoreo aumenta las poblaciones edáficas y, por ende, las relaciones simbióticas. En los ecosistemas altoandinos de la zona norte del Ecuador existen escasas investigaciones sobre esta temática.

Seed bank and growth comparisons of native (Virgilia divaricata) and invasive alien (Acacia mearnsii and A. melanoxylon) plants: implications for conservation [PDF]
Background Invasive alien plants with long-lived dormant seed banks and fast growth rates are difficult to manage. Acacia mearnsii and Acacia melanoxylon are two such invaders in the southern Cape of South Africa which occasionally co-occur with a native,

Hierarchical patterns of correlated mating in Acacia melanoxylon. [PDF]
Abstract Pollen of acacias is transported by insects as polyads, composite pollen grains. The polyad has enough pollen grains to fertilize all ovules within a flower and hence all seed within a pod may be full sibs. Isozyme markers were used to test this hypothesis in two populations of Acacia melanoxylon R.Br.

Regeneration of Acacia melanoxylon plantlets in vitro
Callus from juvenile material of mature Acacia melanoxylon R. Br. trees formed shoots on a Murashige and Skoog’s medium when supplemented with benzyladenine (1μM) and indole-3-acetic acid (1μM). lndole-3-butyric acid at 10μM was the best treatment for the induction and growth of roots on the in vitro-produced shoots.

The influence of heartwood on the pulping properties of Acacia melanoxylon wood [PDF]
The pulping wood quality of Acacia melanoxylon was evaluated in relation to the presence of heartwood. The sapwood and heartwood from 20 trees from four sites in Portugal were evaluated separately at 5% stem height level in terms of chemical composition and kraft pulping aptitude.

Fire effects on the ant community in areas of native and exotic vegetation
Acacia melanoxylon is an invasive species of the mountain grassland of the southeastern part of the Buenos Aires province, Argentina. Fires are a natural disturbance, characteristic of the area, and favor the germination of this invasive plant.

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