Forest Service Enters on Range Research Program in Region Six

Forest Service range research in Region Six, that is, in the States of Oregon and Washington, became a reality with the passage of the Agricultural Appropriation Bill for the fiscal year 1937. Ironically, the region that pioneered range studies, in 1907, was the last west of the hundredth meridian to add range investigations to its formal research program. So soon after its first anniversary, little can be said of research on Oregon and Washington forest ranges other than to discuss briefly the problems to be met, the objectives sought, and the hopes for future accomplishment

Morphological assessment of the Octopus vulgaris species complex evaluated in the light of molecular-based phylogenetic inferences

Cryptic species are common in the ocean, particularly among marine invertebrates such as octopuses. Delineating cryptic species is particularly problematic in octopus taxonomy where the plasticity recorded among taxonomic characters often results in low resolution at the species level. This study investigated the morphological relationships among seven phylogenetic clades (identified using cytochrome c oxidase subunit I) of the broadly distributed Octopus vulgaris species complex and close relatives. Morphological analyses in this study were successful in delimiting O. sinensis, Brazilian O. vulgaris and O. vulgaris sensu stricto, which was congruent with the molecular findings of this study. Analyses based on male morphology were successful in distinguishing 14 of 15 total pairwise comparisons and proved to be a more reliable indicator of species-level relationships in comparison with female morphology. The majority of characters with the greatest discriminatory power were male sexual traits. Significant morphological differences were also recorded among sampling localities of conspecifics, with phenotype showing correlation with local environmental data. The findings of this study support the hypothesis that multiple O. vulgaris-like species are currently being incorrectly treated under a single species name, O. vulgaris. Octopuses being exported globally under the name O. vulgaris are of extremely high fisheries market value and profile. Our findings have potentially significant implications for the naming and conservation of commercially harvested members of this species complex throughout their ranges.Preprint2,793

Structure of the regulatory hyaluronan binding domain in the inflammatory leukocyte homing receptor CD44

Adhesive interactions involving CD44, the cell surface receptor for hyaluronan, underlie fundamental processes such as inflammatory leukocyte homing and tumor metastasis. Regulation of such events is critical and appears to be effected by changes in CD44 N-glycosylation that switch the receptor "on" or "off" under appropriate circumstances. How altered glycosylation influences binding of hyaluronan to the lectin-like Link module in CD44 is unclear, although evidence suggests additional flanking sequences peculiar to CD44 may be involved. Here we show using X-ray crystallography and NMR spectroscopy that these sequences form a lobular extension to the Link module, creating an enlarged HA binding domain and a formerly unidentified protein fold. Moreover, the disposition of key N-glycosylation sites reveals how specific sugar chains could alter both the affinity and avidity of CD44 HA binding. Our results provide the necessary structural framework for understanding the diverse functions of CD44 and developing novel therapeutic strategies

The Centre for Learning and Teaching Associates Scheme: building a learning community for collaboration and impact

This paper presents the outcomes of a small research project that sought to explore the value of a Staff Associate Scheme linked to the Centre for Learning and Teaching (CLT) in a post-92 university. The Associates are a group of academic and professional service staff seconded from their Schools and services for one day a week, usually for a year, to work collaboratively with the core full time Centre for Learning and Teaching team on projects of interest which relate to learning development and align with the strategic aims of the university’s Education Plan. This paper reflects on the findings from narratives provided from autoethnographic Associate reflective diaries and survey responses that sought to explore the participants’ practice experiences, learning journeys, and perceptions of the value of their membership of the Associate Scheme. The discussion is widened by the consideration of findings from the participants, which contributed to the iterative development and enhancement of the Scheme. Findings showed a positive impact of the Scheme on the Associate participants and their practice. They viewed the scheme as beneficial to their collaborative skills, the building of unusual synergies, and in the supporting of innovation and impact as cross-university learning developers. The paper concludes by drawing together themes from the research, lessons learnt, transferability of findings to other universities, and consideration of the requirements for a successful future Scheme

The introduction and refinement of the assessment of digitally recorded audio presentations

This case study critically evaluates benefits and challenges of a form of assessment included in a final year undergraduate Religious Studies Open University module, which combines a written essay task with a digital audio recording of a short oral presentation. Based on the analysis of student and tutor feedback and sample assignments, this study critically examines how teaching and learning practices linked to this novel form of assessment have been iteratively developed in light of the project findings over a period of two years. It concludes that while this form of assessment poses a number of challenges, it can create valuable opportunities for the development of transferable twenty-first-century graduate employability skills as well as deep, effective learning experiences, particularly – though not exclusively – in distance learning settings

Overcoming the barriers to implementing urban road user charging schemes

Urban road user charging offers the potential to achieve significant improvements in urban transport, but is notoriously difficult to implement. Cities need guidance on the range of factors to be considered in planning and implementing such schemes. This paper summarises the results of a 3 year programme which has collated evidence on the issues of most concern to cities. A state of the art report has provided evidence on 14 themes, ranging from objectives and design to implementation and evaluation. A set of 16 case studies has reviewed experience in design and implementation across Europe. The paper summarises their findings, provides references to more detailed information, presents the resulting policy recommendations to European, national and local government, and outlines the areas in which further research is needed

Wikipedia as an encyclopaedia of life

In his 2003 essay E O Wilson outlined his vision for an “encyclopaedia of life” comprising “an electronic page for each species of organism on Earth”, each page containing “the scientific name of the species, a pictorial or genomic presentation of the primary type specimen on which its name is based, and a summary of its diagnostic traits.” Although the “quiet revolution” in biodiversity informatics has generated numerous online resources, including some directly inspired by Wilson's essay (e.g., "http://ispecies.org":http://ispecies.org, "http://www.eol.org":http://www.eol.org), we are still some way from the goal of having available online all relevant information about a species, such as its taxonomy, evolutionary history, genomics, morphology, ecology, and behaviour. While the biodiversity community has been developing a plethora of databases, some with overlapping goals and duplicated content, Wikipedia has been slowly growing to the point where it now has over 100,000 pages on biological taxa. My goal in this essay is to explore the idea that, largely independent of the efforts of biodiversity informatics and well-funded international efforts, Wikipedia ("http://en.wikipedia.org/wiki/Main_Page":http://en.wikipedia.org/wiki/Main_Page) has emerged as potentially the best platform for fulfilling E O Wilson’s vision

Building A Sense Of Belonging In Students: Using A Participatory Approach With Staff To Share Academic Practice

This paper outlines ongoing work undertaken by a university educational development team to strengthen and share colleagues’ academic practice in relation to inclusive learning and teaching activities interventions. The paper outlines our institutional “Fora” structure (coordinated by The Centre for Learning and Teaching) and, taking one of the three Forum events as a modelled example, shows how consideration of the research literature informed colleagues’ discussion and catalysed the sharing of written and oral best practice through participatory action research (PAR) to ultimately build a resource guide. This paper specifically focuses on exploring the different approaches that colleagues adopted to build their students’ “sense of belonging” (both for the face to face and online experiences). A student’s perceived strong sense of belonging to their university can be a core factor in enhancing student satisfaction, engagement and retention (Pickford, 2016; Thomas, 2014). Critique and consideration of Ahn & Davis’ s (2019) four domains of belonging formed the starting point for the discussion. Digital tools and pedagogic approaches sourced from colleagues who have found them valuable in developing student engagement and belonging during the Covid-19 crisis are also explored
