Non-native tree species are widely used in forest plantations. This may have negative consequences for biodiversity. Hitherto, most studies compared diversity between native and non-native stands, which makes it difficult to separate the impact of per se from stand characteristics. Our study, conducted south Sweden, compares saproxylic beetle across different nutritional groups, dead wood two f...

During a survey of ophiostomatoid fungi in native forests of southern Argentina, several isolates of Huntiella species were obtained from Nothofagus trees. Sequences of multiple gene regions were used to identify these fungi, and their pathogenicity was tested on N. pumilio and N. dombeyi. Phylogenetic analyses revealed a novel taxon described here as H. decorticans sp. nov. Inoculations on N. ...

A programme of planting native trees on Quail Island in Lyttelton Harbour has been proposed by the Otamahua/Quail Island Ecological Restoration Trust. The impact that this would have on the Maori and European historic and archaeological sites on the island is assessed. It is concluded that in several areas the planting and growth of trees would adversely affect these sites (some of which are pr...

Advice is given on the impact to native trees of taking tree cores for research purposes. Suggested guidelines for DoC decision making on issuing permits for tree coring are provided.

Abstract Anthropogenic disturbances, including land use change and exotic species, can alter the diversity dynamics of ant communities. To examine foraging behavior in an urbanized habitat northern California, we surveyed presence 9 species on 876 trees across 4 seasons during both day night a 9.5-hectare oak-exotic woodland. Ants were more likely to be observed native, evergreen trees, suggest...

Species richness, resource availability, and disturbance are the primary factors considered in assessing the invasibility of plant communities. Nonetheless, the density of individuals in a community is a common and easy trait to measure. The ecological significance of the density of both native and invasive tree species was assessed using a systematic review and formal meta-analysis. The densit...
