Acacia invasion triggers cascading effects above- and belowground in fragmented forests [PDF]

open access: yesNeoBiota
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

open access: yesRevista 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.

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

open access: yesPeerJ, 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,

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

open access: yesGenetics, 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.

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

open access: yesAnnals 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.

Fire effects on the ant community in areas of native and exotic vegetation

open access: yesSociobiology, 2019
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.

Potential suppressive effects of alien Acacia melanoxylon on Afrotemperate Forest tree recruitment [PDF]

open access: yes, 2022
Acacia melanoxylon R.Br. is a prominent alien and invasive species in many parts of the world and evidence exists of its adverse effects on indigenous forest community composition through allelopathy and alteration of light regimes.

A Comparison of Mobile Laser Scanning Data Acquisition Methods in Closed Forest, Open Woodland and Sub‐Alpine Woodland Ecosystems

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that the mobile laser scanning (MLS) sampling density required to reliably characterise vegetation structure increases with a site's structural complexity. Applying a five‐level acquisition framework across open woodland, closed forest and sub‐alpine woodland ecosystems, we found that longer scanning paths increased the ...
