https://www.selleckchem.com/products/dtnb.html Public communication represents a vital civic function for governments developing climate policies, particularly with vulnerable communities under environmental justice mandates. In this study, three videos developed to support a state's climate change public engagement are used to evaluate how governmental communication using the frames of health, science, and local effects influences two theoretically important constructs, risk perception and collective efficacy. Vulnerable audiences differentiated by stress, perceived lack of control, and poor health demonstrate significant gains in collective efficacy relative to risk-"danger control" -after the intervention. But we find no differences between the three frames in their effects on perceptions of climate change risk and collective efficacy.Biological invasions are a major driver of human-induced global environmental change. This makes monitoring of potential spread, population changes and control measures necessary for guiding management. We illustrate the value of integrated methods (species distribution modelling (SDM), plant population monitoring and questionnaires) for monitoring and assessing invasions of Heracleum mantegazzianum (giant hogweed) over time in Switzerland. SDMs highlighted the potential spread of the species, uncovered ecological mechanisms underlying invasions and guided monitoring at a regional level. We used adaptive and repeat plant sampling to monitor invasive population status and changes, and assess the effectiveness of H. mantegazzianum management over three periods (2005, 2013 and 2018) within the pre-Alps, Vaud. We also conducted questionnaire surveys with managers and the public. Multiscale modelling, and integrating global and regional SDMs, provided the best predictions, showing that H. mantegazzianum can potentially invade large parts of Switzerland, especially below 2 000 m a.s.l. Over time, populations of invasive H. mantegazzianum
