Plagiodera versicolora, a willow beetle living on S. sachalinensis, is found on S. integra during early June in Hokkaido Island, Japan. This insect selects several species of willows (Salix), including S. integra as host plant in Honshu Island of Japan. To determine the reasons for the limited distribution of this beetle on the willows of Hokkaido, the feeding preference of the insect to leaves...

Accounting for climate change in invasive species risk assessments improves our understanding of potential future impacts and enhances our preparedness for the arrival of new non-native species. We combined traditional risk assessment for invasive species with habitat suitability modeling to assess risk to biodiversity based on climate change. We demonstrate our method by assessing the risk for...

Abstract Japanese knotweed ( Reynoutria japonica Houtt.) is an invasive Asian plant abundant along rivers in its introduced range. In riparian areas, floods and ice flows uproot the rhizomes, facilitating their dissemination downstream. Control of large, well-established R. clones areas difficult if use herbicides prohibited. An alternative to controlling entrenched rapid detection manual unear...
