Grasping at the routes of biological invasions: a framework for integrating pathways into policy
A framework is proposed to facilitate the comparative analysis of invasion pathways by a wide range of taxa in both terrestrial and aquatic ecosystems and helps identify existing gaps in current knowledge of pathways and highlight the limitations of existing legislation to manage introductions of alien species.
Alien species in a warmer world: risks and opportunities.
A recent latitudinal and altitudinal expansion of the pine processionary moth, Thaumetopoea pityocampa, whose larvae build silk nests and feed on pine foliage in the winter is reported, attributed to increased winter survival due to a warming trend over the past three decades.
Ecological effects of invasive alien insects
The effects caused by different insect invaders are reviewed according to their ecosystem roles, i.e. herbivores, predators, parasites, parasitoids and pollinators; the level of biological organisation at which they occur; and the direct and indirect mechanisms underlying these effects.
How well do we understand the impacts of alien species on ecosystem services? A pan-European, cross-taxa assessment
Recent comprehensive data provided through the DAISIE project (www.europe-aliens.org) have facilitated the development of the first pan-European assessment of the impacts of alien plants,
Disentangling the role of environmental and human pressures on biological invasions across Europe
The strong influence of economic and demographic variables on the levels of invasion by alien species demonstrates that future solutions to the problem of biological invasions at a national scale lie in mitigating the negative environmental consequences of human activities that generate wealth and by promoting more sustainable population growth.
No saturation in the accumulation of alien species worldwide
It is shown that the annual rate of first records worldwide has increased during the last 200 years, with 37% of all first records reported most recently (1970–2014), highlighting that past efforts to mitigate invasions have not been effective enough to keep up with increasing globalization.
Socioeconomic legacy yields an invasion debt
It is shown that across 10 taxonomic groups in 28 European countries, current numbers of alien species established in the wild are indeed more closely related to indicators of socioeconomic activity from the year 1900 than to those from 2000, although the majority of species introductions occurred during the second half of the 20th century.
Other Hemiptera Sternorrhyncha (Aleyrodidae, Phylloxeroidea, and Psylloidea) and Hemiptera Auchenorrhyncha.
Apart from aphids and scales, 52 additional Sternorrhyncha hemipteran species alien to Europe have been identifi ed within Aleyrodidae (27 whitefl y species), Phylloxeroidea (9 adelgids, 2
Role of Human-Mediated Dispersal in the Spread of the Pinewood Nematode in China
Evidence is provided that human-induced dispersal plays a fundamental role in the spread of the pinewood nematode in China, and appropriate control measures should be taken to stop or slow its expansion.
