Burns and the Borders of Poetry in the Letters of James Wodrow and Samuel Kenrick
Full text linkThe rich and lengthy correspondence (1750–1810) between the Ayrshire minister, James Wodrow, and his friend Samuel Kenrick contains four pairs of letters which discuss how much local knowledge was required to understand and appreciate the Scots poetry of Robert Burns, located in their own ongoing conversation about the transferability of language beyond borders. Wodrow was deeply embedded in the church and social life of Burns’s Ayrshire, while Kenrick, a Welshman living in England, also had substantial roots in the southwest of Scotland. Their discussions present an example of informal but informed literary criticism in the Enlightenment, beyond the circles of the celebrated literati or published reviewers
Patterns of declining zooplankton energy in the northeast Atlantic as an indicator for marine survival of Atlantic salmon
Full text linkReturn rates of Atlantic salmon (Salmo salar) from the sea to European rivers have declined in recent decades. The first months at sea are critical for growth and survival; recent evidence suggests that reduced food availability may be a contributory factor to the observed declines. Here, zooplankton abundance data are used to derive a measure of prey energy available to forage fish prey of salmon during early marine migration. This zooplankton prey energy has significantly and dramatically declined over much of the northeast Atlantic, and specifically within key salmon migration domains, over the past 60 years. Marine return rates from a set of southern European populations are found to exhibit clustering not entirely predictable from geographical proximity. Variability in grouped return rates from these populations is correlated with zooplankton energy on a range of scales, demonstrating the potential use of zooplankton energy as an indicator of salmon marine survival. Comparison with environmental variables derived from ocean model reanalysis data suggests zooplankton energy is regulated by a combination of climate change impacts on ecosystem productivity and multi-decadal variability in water mass influence along the migration routes
Survival and transfer potential of Salmonella enterica serovar Typhimurium colonising polyethylene microplastics in contaminated agricultural soils
Full text linkAgricultural environments are becoming increasingly contaminated with plastic pollution. Plastics in the environment can also provide a unique habitat for microbial biofilm, termed the ‘plastisphere’, which can also support the persistence of human pathogens such as Salmonella. Human enteric Salmonella enterica serovar Typhimurium can enter agricultural environments via flooding or from irrigation with contaminated water. Using soil mesocosms we quantified the ability of S. Typhimurium to persist on microplastic beads in two agriculturally relevant soils, under ambient and repeat flood scenarios. S. Typhimurium persisted in the plastisphere for 35 days in both podzol and loamy soils; while during multiple flood events was able to survive in the plastisphere for up to 21 days. S. Typhimurium could dissociate from the plastisphere during flooding events and migrate through soil in leachate, and importantly could colonise new plastic particles in the soil, suggesting that plastic pollution in agricultural soils can aid S. Typhimurium persistence and facilitate further dissemination within the environment. The potential for increased survival of enteric human pathogens in agricultural and food production environments due to plastic contamination poses a significant public health risk, particularly in potato or root vegetable systems where there is the potential for direct contact with crops
Bdelloid rotifers deploy horizontally acquired biosynthetic genes against a fungal pathogen
Full text linkCoevolutionary antagonism generates relentless selection that can favour genetic exchange, including transfer of antibiotic synthesis and resistance genes among bacteria, and sexual recombination of disease resistance alleles in eukaryotes. We report an unusual link between biological conflict and DNA transfer in bdelloid rotifers, microscopic animals whose genomes show elevated levels of horizontal gene transfer from non-metazoan taxa. When rotifers were challenged with a fungal pathogen, horizontally acquired genes were over twice as likely to be upregulated as other genes — a stronger enrichment than observed for abiotic stressors. Among hundreds of upregulated genes, the most markedly overrepresented were clusters resembling bacterial polyketide and nonribosomal peptide synthetases that produce antibiotics. Upregulation of these clusters in a pathogen-resistant rotifer species was nearly ten times stronger than in a susceptible species. By acquiring, domesticating, and expressing non-metazoan biosynthetic pathways, bdelloids may have evolved to resist natural enemies using antimicrobial mechanisms absent from other animals
Born4Life: Creating and Supporting Meaningful, Authentic Intergenerational Experiences
Full text linkIntergenerational Practice, which brings two or more generations together for mutual benefit, is growing in popularity in the United Kingdom. While practices are well meaning, they are not always research informed. This critical evaluation research draws upon an evaluation of meaningful practice undertaken by Born4Life practitioners; a network of early years educators based in some Early Years settings across the UK, who are on an intergenerational journey. Through surveys, focus groups, and interviews, this research aimed to determine what an intentional, meaningful, and sustainable intergenerational community looks like and how such communities can be supported by identifying training and development requirements for the intergenerational team
Women’s experiences of seeking healthcare for abdominal pain in Ireland: a qualitative study
Full text linkBackground Evidence suggests that women's abdominal pain is more likely to be minimised or dismissed by healthcare professionals than men's. This can have a detrimental impact on health-related outcomes as well as quality of life. The aim of this study was to explore women's experiences of seeking healthcare for abdominal pain in Ireland. Method A qualitative design and opportunity sampling approach were employed in this study. Fourteen women living in Ireland with experience of seeking healthcare for abdominal pain took part in one-to-one semi-structured interviews via video-conferencing software. Data were analysed using reflexive thematic analysis. Results Four themes were constructed from the data: [1] "Just Get on with It"-Normalisation and Invalidation; [2] "Bad Enough"? Costs of (Not) Seeking Help; [3] "Fight Your Case, " Fight for Care; and [4] "Out of the Loop"-Systemic Barriers to Care. Perceived invalidation of pain by healthcare professionals was common, as was internalised normalisation of pain. This created challenges when negotiating pain management solutions. Despite functional interference, participants felt their pain needed to reach an extreme level of severity before seeking help. Costs of private healthcare were implicated in delayed help-seeking. Participants felt the onus was on them to fight for care. Social support and information-seeking facilitated participants in this fight while systemic issues were identified as barriers to adequate care. Despite their frustrations, participants expressed empathy for healthcare professionals operating in a flawed system. Conclusions Participants described mostly negative experiences of seeking healthcare for abdominal pain, characterised by dismissal of symptoms and internalisation of normative views of women's pain as less worthy of care. These experiences reinforced participants' views that self-advocacy is essential to access care for their pain. There are systemic issues at play within the Irish healthcare system that limit women's ability to access abdominal pain management support. Education and training for healthcare professionals on the Gender Pain Gap and its implications for patient care, as well as clear referral pathways for women presenting with abdominal pain, may help to ensure more equitable healthcare delivery for individuals with abdominal pain in Ireland
A family of process-based models to simulate landscape use by multiple taxa
Full text linkContext Land-use change is a key driver of biodiversity loss. Models that accurately predict how biodiversity might be affected by land-use changes are urgently needed, to help avoid further negative impacts and inform landscape-scale restoration projects. To be effective, such models must balance model realism with computational tractability and must represent the different habitat and connectivity requirements of multiple species. Objectives We explored the extent to which process-based modelling might fulfil this role, examining feasibility for different taxa and potential for informing real-world decision-making. Methods We developed a family of process-based models (*4pop) that simulate landscape use by birds, bats, reptiles and amphibians, derived from the well-established poll4pop model (designed to simulate bee populations). Given landcover data, the models predict spatially-explicit relative abundance by simulating optimal home-range foraging, reproduction, dispersal of offspring and mortality. The models were co-developed by researchers, conservation NGOs and volunteer surveyors, parameterised using literature data and expert opinion, and validated against observational datasets collected across Great Britain. Results The models were able to simulate habitat specialists, generalists, and species requiring access to multiple habitats for different types of resources (e.g. breeding vs foraging). We identified model refinements required for some taxa and considerations for modelling further species/groups. Conclusions We suggest process-based models that integrate multiple forms of knowledge can assist biodiversity-inclusive decision-making by predicting habitat use throughout the year, expanding the range of species that can be modelled, and enabling decision-makers to better account for landscape context and habitat configuration effects on population persistence
Substantial increase of organic carbon storage in Chinese lakes
Full text linkPrevious studies typically assumed a constant total organic carbon (OC) storage in the lake water column, neglecting its significant variability within a changing world. Based on extensive field data and satellite monitoring techniques, we demonstrate considerable spatiotemporal variability in OC concentration and storage for 24,366 Chinese lakes during 1984–2023. Here we show that dissolved OC concentration is high in northwest saline lakes and particulate OC concentration is high in southeast eutrophic lakes. Along with increasing OC concentration and water volume, dissolved and particulate OC storage increase by 44.6% and 33.5%, respectively. Intensified human activities, water input, and wind disturbance are the key drivers for increasing OC storage. Moreover, higher OC storage further leads to an 11.0% increase in nationwide OC burial and a decrease in carbon emissions from 71.1% of northwest lakes. Similar changes are occurring globally, which suggests that lakes are playing an increasingly important role in carbon sequestration
Low-intensity logging alters species and functional composition, but does not negatively impact key ecosystem services in a Central African tropical forest
Full text linkSelective logging can impact tree composition and the long-term sustainability of forests. Studying the ecological consequences of logging practices is crucial for guiding forest management strategies aiming at maintaining ecological integrity and supporting landscape-level conservation goals. We investigated the consequences of very low-intensity selective logging in multiple tree life stages across a logged forest chronosequence in Gabon. We found that species composition differed between logged and unlogged forests at all life stages (seedlings, saplings, and adults), which were most pronounced in the understory of older forests (logged 10 years prior) compared to unlogged areas. However, logging explained a small portion of the variation in species composition (<3% alone, <8% in combination with habitat). For functional composition, we observed higher wood density in the understory of older logged forests than in unlogged forests. Light-demanding saplings and saplings with animal-dispersed seeds were more prevalent in older logged forests than in unlogged forests. Timber species were less prevalent as seedlings and adults but more prevalent as saplings in logged forests compared to unlogged forests. Our results suggest that very low-intensity logging does not negatively impact key ecosystem services like carbon storage and food availability for frugivores. However, reduced prevalence of timber species may impact logging sustainability. Our study indicates that, when considering best-case scenarios, selectively logged forests have the potential to support conservation goals by offering refugia for biodiversity and maintaining essential ecosystem services. Thus, these forests have the potential to complement protected areas and serve as a sustainable alternative to more intensive land us
Health visiting in the UK in light of the COVID-19 pandemic experience: (RReHOPE) findings from a realist review
Full text linkBackground: Child health programmes in the United Kingdom offer every child and their family an evidence-based programme to support child health and development. During the COVID-19 pandemic, health visiting services in many areas were reduced to a partial service, with significant variability between and within the four United Kingdom countries. This study investigated the impact of the pandemic on health visiting services and developed recommendations for policy and practice. Objectives: Conduct a realist review of relevant literature. Engage with key stakeholders in policy, practice and research across the United Kingdom. Identify recommendations for improving the organisation and delivery of health visiting services, with a focus on services being equitable, effective and efficient. Review methods: The realist review followed Pawson's five iterative steps and involved key stakeholder representatives at every step. We searched five electronic databases and references of included articles, as well as relevant organisational websites, to find quantitative, qualitative, mixed-methods and grey literature related to health visiting services in the United Kingdom during the COVID-19 pandemic. An assessment of their relevance to our initial programme theory determined inclusion in the review. Data were extracted, organised and presented as draft context, mechanism and outcome configurations. These were iteratively refined through meetings with 6 people with lived experience of caring for babies during the pandemic and 23 professional stakeholders. Context, mechanism and outcome configurations were then translated into findings and recommendations. Results: One hundred and eighteen documents contributed to the review and collectively revealed the far-reaching, uneven and enduring impact of the COVID-19 pandemic on babies and families. Data uncovered significant concerns of families and practitioners amidst the pandemic, along with the service's corresponding actions. These concerns and responses underscored the critical importance of fostering and sustaining trusting relationships between health visitors and families, as well as conducting holistic assessments for early intervention. Although we found minimal evidence of decision-making within organisational/managerial levels, the data illustrated the diverse and complex nature of health visiting work and the need for flexibility and resourcefulness. Limitations: The primary limitation of this review was a lack of specific evidence from the United Kingdom nations other than England. There was also a lack of data focusing on changes during the COVID-19 pandemic at a local management level. Conclusions: The needs of babies, children and families, and the delivery of services to support them, were not prioritised in the early phase of the pandemic response. Our data show that the health visiting service was concerned with maintaining visibility of all children, and especially supporting families with a new baby. Health visiting services adapted in numerous ways to respond to these concerns. Implications for policy and practice are presented, identified from our analysis and discussions with stakeholders. Future work: The RReHOPE study is part of a jigsaw of evidence, which will provide a much stronger evidence base for future policy and practice. This realist review presents several areas for future research, including how health visiting is organised at local management level; how to optimise limited resources; factors affecting differing uptake in different regions; and analysis of the effectiveness of health visiting using large cohort studies
