Large areas of tropical forest have been cleared and planted with exotic grass species for use as cattle pasture. These often remain persistent grasslands after grazer removal, which is problematic for restoring native forest communities. It is often hoped that remnant and/or planted trees can...

The present work consisted of presenting some of the main results about the use of taper models in different native and exotic species, except for pinus and Eucalyptus, in the different regions of Brazil. Many works were carried out, mainly, in the South, North, Southeast and Center-West....

This paper presents the first detailed assessment of the invasive potential of Melaleuca hypericifolia Sm. in South Africa. This woody, fire-adapted shrub, native to Australia, is considered a high risk invader which could potentially occupy 4% of the country if allowed to spread. As such, it is a...

In April 2015, Armillaria rhizomorphs were collected from Koa (Acacia koa) and 'O¯hi'a lehua (Metrosideros polymorpha) on the island of Kaua'i, Hawaii, USA. Based on somatic pairing tests, isolates were assigned to 2 genets or clones of the same species. The causal pathogen was identified as ...

Introduced species lists provide essential background information for biological invasions research and management. The compilation of these lists is, however, prone to a variety of errors. We highlight the frequency and consequences of such errors using introduced Melaleuca (sensu lato, including ...

Numerous pollinators are declining across the world. One of these, the swift parrot (Lathamus discolor) is a critically endangered Australian bird that feeds largely on the nectar and pollen of Eucalyptus trees. The Swift Parrot Recovery Plan includes competition for food from introduced social...

Alien invasive species are posing a serious and direct threat to biodiversity, water security, and productive use of land in South Africa. Most of these species need to be cleared and are therefore regarded as waste material, which could become raw material for wood-plastic composites (WPCs). WPCs...

This study aimed to examine the allelopathic potential of Eucalyptus and Calotropis species on seed germination and seedling growth of Acacia ehrenbergiana (Hayne), Acacia gerrardii (Benth.) and Acacia tortilis (Forssk.). The aqueous leaf extracts of Eucalyptus camaldulensis var. obtusa (Blakely), ...

The decomposition of large vertebrate carcasses generates small-scale disturbances characterized by changes in soil chemistry and new opportunities for plant establishment. Yet few studies have examined whether this effect is still evident several years after death, or has consequences for...

Sintra's Cultural Landscape is a World Heritage Site and was the first cultural landscape to be listed in Europe by UNESCO, in 1995. It is a privileged ecosystem with natural and cultural value classified as priorities for conservation. Parques de Sintra-Monte da Lua is a state-owned company...
