Invasiveness, ecological impacts and control of acacias in southwestern Europe – a review [PDF]

Web Ecology, 2020
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]

NeoBiota
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

Análisis de las poblaciones edáficas en suelos con sistemas silvopastoriles dedicados a la producción lechera, en la finca San Vicente, El Carmelo, Ecuador

Revista Criterios, 2021
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.

Hierarchical patterns of correlated mating in Acacia melanoxylon. [PDF]

Genetics, 1991
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.

Seed bank and growth comparisons of native (Virgilia divaricata) and invasive alien (Acacia mearnsii and A. melanoxylon) plants: implications for conservation [PDF]

PeerJ, 2018
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,

Dietary Variability Among Mountain Gorilla Groups Across Volcanoes National Park, Rwanda. [PDF]

Ecol Evol
Dietary variability among mountain gorilla groups in Volcanoes National Park (VNP) was analyzed to understand how habitat differences influence diet and whether diet quality accounts for variations in population growth rates. The study found distinct diets with minimal overlap between southwest and northeast groups but comparable nutrient ...

The influence of heartwood on the pulping properties of Acacia melanoxylon wood [PDF]

Journal of Wood Science, 2008
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.
