Addressing the Elephant in the Room: A Quantitative Approach to Understanding 'Wild'

The concept of "wild" is poorly defined when applied to non-human animals, despite its central role in conservation, wildlife management and environmental policy. Despite numerous attempts to define "wildness", the distinction between "wild" and "non-wild" remains inconsistently applied. A shared, empirically grounded understanding of wildness would strengthen communication, support policy and legislation, and clarify human attitudes towards wildlife and nature. We assessed whether a shared understanding of wildness exists within the research community. A total of 358 professionals from different fields completed an online survey comprising 44 wildness-related statements along established measures of attitude and acceptability toward wildlife (AATW) and nature-relatedness (NRS). . Exploratory Factor Analysis revealed six components (19 statements): Human-mediated animal availability, Urbanisation, Independence from humans, Human-wildlife perceived conflict, Individual history of wildness, and Feralisation. These factors explained 43.91% of the variance. Mediation analysis showed that urbanisation and human-wildlife perceived conflict shape nature-relatedness by influencing attitudes and acceptability towards wildlife. Respondents demographic and professional backgrounds influenced their conceptualisation of wildness. While there is a shared latent structure of wildness across fields, it is multidimensional. This has implications for developing working definitions applicable to research, policy and practice.

The timid invasion: Behavioral adjustments favor range expansion in a non-native rodent

In biological invasion processes animal behavior moderates the success of invasive species, and the native faunas ability to adapt. The importance of behavioral syndromes and flexibility of invading species for invasion success remains debated. We investigated behavior of rodents, the bank vole (Myodes glareolus) currently invading Ireland, and the native wood mouse (Apodemus sylvaticus) that declines with vole invasion, at replicated sites at pre-invasion, edge, and source of the invasion. We found that individual rodents varied consistently in risk-taking behaviors, and mice had not adapted to the presence of invasive voles. Voles at the invasion edge were more careful but also more flexible compared to voles the invasion source. The ability to develop timid and flexible phenotypes may contribute to the invasion success of rodents worldwide.
