Whether introduced into a completely novel habitat or slowly expanding their current range,the degree to which animals can effciently explore and navigate new environments can be key to survival,ultimately determining population establishment and colonization *** tested whether spatial orientation and exploratory behavior are associated with non-native spread in free-living bank voles(Myodes glareolus,N=43)from a population accidentally introduced to Ireland a century *** measured spatial orientation and navigation in a radial arm maze,and behaviors associated to exploratory tendencies and risk-taking in repeated open-feld tests,at the expansion edge and in the source *** voles at the expansion edge re-visited unrewarded arms of the maze more,waited longer before leaving it,took longer to start exploring both the radial arm maze and the open feld,and were more risk-averse compared to conspecifcs in the source *** together,results suggest that for this small mammal under heavy predation pressure,a careful and thorough exploration strategy might be favored when expanding into novel environments.

Widespread changes to forested watersheds affected by the mountain pine beetle (Dendroctonus ponderosae Hopkins) epidemic across western North America raised concerns about the effects of this climate-induced disturbance on drinking water and natural resources. Effective communication and knowledge exchange across scientists and stakeholders (i.e., drinking water managers) is essential for constructively responding to such landscape scale disturbances, providing improved adaptive capacity through knowledge sharing. An assessment of stakeholder knowledge levels, information needs, primary concerns, and suggested communication strategies were conducted via an online elicitation survey and World Science Café workshops. Knowledge levels, assessed via a survey of local water managers and experts, were relatively low with approximately half of the respondents reporting little to no knowledge of the effects of mountain pine beetle on drinking water quality and quantity, thereby indicating limited knowledge exchange between scientists and drinking water stakeholders. Increased accessibility and dissemination of research findings pertinent to the mountain pine beetle epidemic’s effects on drinking water quality and quantity is necessary for natural resource management. Recommendations for improved communication among scientists and drinking water stakeholders in particular and forest health in general include dispersal of non-academic research summaries, information exchange through existing media and community resources, demonstration projects, and information clearinghouses. This information provides a better understanding of the challenges, concerns, and first-hand experience of stakeholders of a landscape disturbance issue to apply this knowledge to enhance land management practice and how researchers on this overall project enhanced science communication efforts.
