Non-native organisms have invaded novel ecosystems for centuries, yet we only a limited understanding of why their impacts vary widely from minor to severe. Predicting the impact non-established or newly detected species could help focus biosecurity measures on with highest potential cause widespread damage. However, predictive models require an drivers and appropriate level at which these shou...

Abstract Deforestation represents an important contributor to climate change. For this reason, identifying conditions that enable the adoption of policies halting or reversing process is crucial avoid catastrophic The Argentinian Gran Chaco a hotspot deforestation, mainly due expansion capital-intensive agriculture. In Argentina, introduction national forest law (NFL) step protect remaining for...

1. Large-scale invasions of riparian trees can alter the quantity and quality of allochthonous inputs of leaf litter to streams and thus have the potential to alter stream organic matter dynamics. Non-native saltcedar (Tamarix sp.) and Russian olive (Elaeagnus angustifolia) are now among the most common trees in riparian zones in western North America, yet their impacts on energy flow in stream...

Disturbances can facilitate the spread of exotic plants, which establish mutualisms with bees, constituting invader complexes. However, a disturbance-mediated increase in flower resources also promote native floral visitors due to fact that plant-pollinator interactions are generalist. We experimentally tested these ideas northern Patagonian woodlands. In three sites, we examined effect harvest...

The health and sustainability of trees are increasingly under threat from biotic abiotic sources, including rising incidences non-native invasive plant pests pathogens. island Ireland (Ireland Northern Ireland) is generally understood to have a high status, due its status because the national international regulations aimed at protecting health. To establish baseline current pest pathogen threa...

Two breeding populations of the non-native Asian longhorned beetle (Anoplophora glabripennis Motschulsky), a pest broadleaf trees in its native China, were discovered Ontario 2003 and 2013, respectively. Both eradicated by removing all injured uninjured deemed at high risk injury. We used data collected during this removal to study host selection. Signs A. injury observed on 732 stems from seve...
