Abstract Risk assessments of biological invasions rarely account for native species performance and community features, but the assessment presented here could provide additional insights management aimed at decreasing vulnerability or increasing resistance a plant to invasions. To gather information on drivers communities’ invasion, we conducted literature search meta-analysis. Using data coll...

PURPOSE Radiotherapy remains a major therapeutic option for patients with advanced pancreatic cancer. Nevertheless, the effects of irradiation on malignant biological behaviors (e.g., migration and invasion of cancer cells) have yet to be clarified. Thus, we conducted an in vitro study to investigate the radiation-induced alterations around cell migration and invasion capacity. EXPERIMENT DES...

Many biological invasions do not occur as a gradual expansion along a continuous front, but result from the expansion of satellite populations that become established at 'invasion hubs'. Although theoretical studies indicate that targeting control efforts at invasion hubs can effectively contain the spread of invasions, few studies have demonstrated this in practice. In arid landscapes worldwid...

Aim Knowledge of how effective interceptions and quarantine measures are in preventing new biological invasions is of paramount importance for maintaining ecosystem function in a rapidly changing world. Here, we determine current macrogeographic population structure and routes of invasion of the Mediterranean fruit fly (Ceratitis capitata) using genetic approaches and reconstruct and test invas...

Biological invasions are a global issue with far-reaching consequences for single species, communities and whole ecosystems. Our understanding of modes and mechanisms of biological invasions requires knowledge of the genetic processes associated with successful invasions. In many instances, this information is particularly difficult to obtain as the initial phases of the invasion process often ...

Understanding the implications of different management strategies is necessary to identify best conservation trajectories for ecosystems exposed to anthropogenic stressors. For example, science-based risk assessments at large scales are needed to understand efficacy of different vector management approaches aimed at preventing biological invasions associated with commercial shipping. We conduct...

Metastases represent the end products of a multistep cell-biological process termed the invasion-metastasis cascade, which involves dissemination of cancer cells to anatomically distant organ sites and their subsequent adaptation to foreign tissue microenvironments. Each of these events is driven by the acquisition of genetic and/or epigenetic alterations within tumor cells and the co-option of...
