    Quantitative Wood Anatomy—Relating Anatomy to Transverse Tensile Strength

    Get PDF
    The tension perpendicular-to-grain properties of eight North American hardwood species were determined and related to their anatomy. Stereological techniques based on countings of points and intersections were used to quantitatively characterize the anatomy of each species. Modulus of elasticity and proportional limit stress values were found to be more dependent on specific gravity than anatomy. However, the properties associated with failure were closely associated with anatomical features. Earlywood vessel area fraction negatively influenced radial maximum stress and strain, whereas the ray width and area fraction were positively related to the maximum radial properties. Analysis showed that the rays significantly affected the transverse stiffness

    Biocultural approaches to sustainability : A systematic review of the scientific literature

    Get PDF
    Current sustainability challenges demand approaches that acknowledge a plurality of human-nature interactions and worldviews, for which biocultural approaches are considered appropriate and timely. This systematic review analyses the application of biocultural approaches to sustainability in scientific journal articles published between 1990 and 2018 through a mixed methods approach combining qualitative content analysis and quantitative multivariate methods. The study identifies seven distinct biocultural lenses, that is, different ways of understanding and applying biocultural approaches, which to different degrees consider the key aspects of sustainability science-inter- and transdisciplinarity, social justice and normativity. The review suggests that biocultural approaches in sustainability science need to move from describing how nature and culture are co-produced to co-producing knowledge for sustainability solutions, and in so doing, better account for questions of power, gender and transformations, which has been largely neglected thus far.

    Neural Circuits Underlying Rodent Sociality: A Comparative Approach

    Get PDF
    All mammals begin life in social groups, but for some species, social relationships persist and develop throughout the course of an individual’s life. Research in multiple rodent species provides evidence of relatively conserved circuitry underlying social behaviors and processes such as social recognition and memory, social reward, and social approach/avoidance. Species exhibiting different complex social behaviors and social systems (such as social monogamy or familiarity preferences) can be characterized in part by when and how they display specific social behaviors. Prairie and meadow voles are closely related species that exhibit similarly selective peer preferences but different mating systems, aiding direct comparison of the mechanisms underlying affiliative behavior. This chapter draws on research in voles as well as other rodents to explore the mechanisms involved in individual social behavior processes, as well as specific complex social patterns. Contrasts between vole species exemplify how the laboratory study of diverse species improves our understanding of the mechanisms underlying social behavior. We identify several additional rodent species whose interesting social structures and available ecological and behavioral field data make them good candidates for study. New techniques and integration across laboratory and field settings will provide exciting opportunities for future mechanistic work in non-model species

    Exploring the role of outdoor recreation to contribute to urban climate resilience

    Climate resilience is an important mix of climate mitigation and climate adaptation designed to minimize current and future disruption while promoting opportunity. Given the importance of the regional and local arena for consideration of impacts of climate change trends and needs for climate action, climate resilience in one community, Duluth, Minnesota, is considered. At the core of this project is the climate resilience question: what can we currently be doing in our communities to prepare for projected climate change while simultaneously improving life for current residents and visitors? Given the growing importance of outdoor recreation and nature-based tourism in Duluth, the role this sector may be able to play in climate resilience is considered. Using action research methodology, the research process of adjusting, presenting, and conducting follow-up from a National Oceanic and Atmospheric Administration Climate Adaptation for Coastal Communities workshop is presented. The study takes a unique look at one workshop outcome, a Duluth Parks and Recreation planning tool. Specifically, a resilience checklist is presented as a useful sample outcome of the overall process. Beyond the study community, the role of outdoor recreation to serve climate resilience is explored and affirmed

    Exploring access to nature play in urban parks : resilience, sustainability, and early childhood

    Nature play is an important component of the development of resilience in early childhood. Nature play is also an element of urban sustainability through a consideration of access to urban nature. From the foundation of access to nature play as a part of both resilience and sustainability considerations, a mixed-method case study was initiated. Spatial analysis, survey outreach, and focus group methodology have been combined to consider whether city parkland provides access for preschools to incorporate nature play, and, further, whether other barriers may exist to limit or prevent the use of city parks for nature play by preschool programs. The results indicate the existence of quality proximate access, but other factors creating barriers for broader application of nature play exist. The results also illustrate the critical role of public access to public parks as part of urban sustainability and the development of resilience in young children. The implications for the use of city parkland for nature play are presented.

    Ecological sanitation and sustainable nutrient recovery education : considering the three fixes for environmental problem-solving

    In the context of phosphorus as a finite resource and the unsustainable character of current sanitation in Europe, this paper examined social factors in a technological transition towards sustainable sanitation. The evaluation is based on the idea of cognitive, structural, and technological fixes to achieve environmental protection. The cognitive fix has been evaluated through literature and a European-wide survey with universities that offer civil and environmental engineering programs. Contrary to an initial hypothesis, ecological sanitation and nutrient recycling are taught by the majority (66%) of responding programs. There are, however, local differences in terms of context and detail of the education. The main impediments for teaching were identified as academic resources (especially in Belgium, Germany and Denmark) and the technological status quo (Ireland, Italy, Spain and some programs of the United Kingdom). Instructors’ personal commitment and experience was evaluated to be a key factor for an extensive coverage of sustainable sanitation in higher education programs. The role of higher education has a critical role to play in changing sanitation practices, given the unique professional developmental stage of students and the potential for a cognitive fix to contribute to meaningful change
