Abstract Ailanthus altissima is an aggressive invasive tree worldwide, but the ecological factors that lead to spread of this species in Mediterranean ecosystems are still unclear. Here we aim identify such factors, focusing on interaction human activity with climatic conditions. We determined occurrence and abundance 240 sites studied their relationship 20 variables representing climatic, geog...

Abstract Lycorma delicatula (spotted lanternfly) has a broad host range with strong preference for the invasive plant from its native range, tree of heaven ( Ailanthus altissima); it had long been speculated that L. could not develop or reproduce without access to . In 2019, we found this assumption was incorrect, but fitness reduced in absence A. altissima number egg masses laid dramatically f...

In most populations of Solidago altissima, a small proportion of plants have a growth pattern in which the stem bends early in the season so that the apex is pointing downward (i.e., a ‘‘candy-cane’’ stem) then straightens up again later in the season. The majority of plants, however, do not show this pattern. Instead their stems remain erect from emergence through flowering and senescence. It ...

Extrinsic, host-associated environmental factors may influence postmating isolation between herbivorous insect populations and represent a fundamentally ecological cause of speciation. We investigated this issue in experiments on hybrids between the host races of Eurosta solidaginis, a fly that induces galls on the goldenrods Solidago altissima and S. gigantea. To do so, we measured the perform...

A widely accepted hypothesis in invasion ecology is that invasive species have higher survival through the early stages of establishment than do non-invasive species. In this study we explore the hypothesis that the sexual reproductive success of the invasive trees Ailanthus altissima (Mill.) Swingle and Robinia pseudoacacia L. is higher than that of the native Fraxinus angustifolia Vahl., all ...

Scutellaria altissima L. is a common traditional Chinese medicine used to treat inflammation in some countries. Scutellarin, an active major flavone glycoside isolated from the traditional Chinese medicine Scutellaria altissima L., has been shown to offer various beneficial biochemical effects on cerebrovascular diseases and inflammation. However, the antiproliferative effects of Scutellarin in...
