    National Plans of Action (NPOAs) for reducing seabird bycatch: Developing best practice for assessing and managing fisheries impacts

    Get PDF
    Fisheries bycatch is one of the biggest threats to seabird populations. Managers need to identify where and when bycatch occurs and ensure effective action. In 1999, the Food and Agriculture Organization of the United Nations released the International Plan of Action for Reducing Incidental Catch of Seabirds in Longline Fisheries (IPOA-s) encouraging states to voluntarily assess potential seabird bycatch problems and implement a National Plan of Action (NPOA) if needed. However, the IPOA-s is ambiguous about the steps and objectives, diminishing its value as a conservation tool

    OBJECTIVES: To assess whether it is feasible to quantify acute change in temporal lobe volume and total oedema volumes in herpes simplex virus (HSV) encephalitis as a preliminary to a trial of corticosteroid therapy. METHODS: The study analysed serially acquired magnetic resonance images (MRI), of patients with acute HSV encephalitis who had neuroimaging repeated within four weeks of the first scan. We performed volumetric measurements of the left and right temporal lobes and of cerebral oedema visible on T2 weighted Fluid Attenuated Inversion Recovery (FLAIR) images using stereology in conjunction with point counting. RESULTS: Temporal lobe volumes increased on average by 1.6% (standard deviation (SD 11%) in five patients who had not received corticosteroid therapy and decreased in two patients who had received corticosteroids by 8.5%. FLAIR hyperintensity volumes increased by 9% in patients not receiving treatment with corticosteroids and decreased by 29% in the two patients that had received corticosteroids. CONCLUSIONS: This study has shown it is feasible to quantify acute change in temporal lobe and total oedema volumes in HSV encephalitis and suggests a potential resolution of swelling in response to corticosteroid therapy. These techniques could be used as part of a randomized control trial to investigate the efficacy of corticosteroids for treating HSV encephalitis in conjunction with assessing clinical outcomes and could be of potential value in helping to predict the clinical outcomes of patients with HSV encephalitis

    Updating requirements for Endangered, Threatened and Protected species MSC Fisheries Standard v3.0 to operationalise best practices

    This is the final version. Available from Elsevier via the DOI in this record. Bycatch in fisheries is a key threat to non-target marine species, particularly for those species that have life histories with low productivity or poor conservation status. In this paper, the requirements of the new Marine Stewardship Council (MSC) Fisheries Standard (hereafter “the Standard”) are summarised relevant to Endangered, Threatened and Protected (ETP) species. This covers both how species are designated as ETP, and how performance of management is assessed with respect to ETP species, when scoring fisheries against the Standard. The process used to select these requirements is described, including a review of the requirements for earlier versions of the Standard and the scoring of these requirements in assessment reports for a selection of fisheries that have achieved MSC certification. The review identified a lack of consistency in the implementation of scoring guidelines, which was in part due to a lack of clarity in the requirements of the Standard. The revised Standard has been designed to achieve more consistent implementation of the requirements with respect to management of impacts on ETP species, and to align the requirements more closely with global best practice. The requirements may be used as a template for fisheries managers seeking to prioritise bycatch species for improved management and setting more specific and measurable objectives in relation to population status and minimising mortalities.Marine Stewardship Counci

    Background: This study sought to establish the long-term effects of Covid-19 following hospitalisation. Methods: 327 hospitalised participants, with SARS-CoV-2 infection were recruited into a prospective multicentre cohort study at least 3 months post-discharge. The primary outcome was self-reported recovery at least ninety days after initial Covid-19 symptom onset. Secondary outcomes included new symptoms, disability (Washington group short scale), breathlessness (MRC Dyspnoea scale) and quality of life (EQ5D-5L). Findings: 55% of participants reported not feeling fully recovered. 93% reported persistent symptoms, with fatigue the most common (83%), followed by breathlessness (54%). 47% reported an increase in MRC dyspnoea scale of at least one grade. New or worse disability was reported by 24% of participants. The EQ5D-5L summary index was significantly worse following acute illness (median difference 0.1 points on a scale of 0 to 1, IQR: -0.2 to 0.0). Females under the age of 50 years were five times less likely to report feeling recovered (adjusted OR 5.09, 95% CI 1.64 to 15.74), were more likely to have greater disability (adjusted OR 4.22, 95% CI 1.12 to 15.94), twice as likely to report worse fatigue (adjusted OR 2.06, 95% CI 0.81 to 3.31) and seven times more likely to become more breathless (adjusted OR 7.15, 95% CI 2.24 to 22.83) than men of the same age. Interpretation: Survivors of Covid-19 experienced long-term symptoms, new disability, increased breathlessness, and reduced quality of life. These findings were present in young, previously healthy working age adults, and were most common in younger females.

    Evaluating the appropriateness of risk-based approaches to assess the sustainability of fishery impacts on seabirds

    Get PDF
    Many seabird populations are declining, with fisheries bycatch as one of the greatest threats. Explicit risk criteria should be used to identify whether bycatch is a problem for particular species and fisheries, but these are often poorly defined. A variety of methods are used to determine the risk that a specific fishery is having an unsustainable impact on a seabird population. Up until October 2022, the Marine Stewardship Council (MSC) applied a general semi-quantitative productivity susceptibility analysis (PSA), a tool that has also been used widely by other management agencies for diverse taxa. Given the need to ensure fisheries risk assessments are robust and consistent, we examined how general PSAs perform when applied in 2 situations with good information on both the seabird population and fisheries bycatch rates and compare the outputs with those from 2 accessible and more quantitative tools: potential biological removal and population viability analysis. We found that risk scoring using the previous MSC version of the PSA was less robust and precautionary than using other approaches, given the steep declines observed in some seabird breeding populations. We make recommendations on how to select attributes for species-specific PSAs and, depending on the data available, identify the most appropriate risk assessment method to achieve a given objective. These should help ensure more consistent assessment and prioritisation of seabird bycatch issues, and improved ecosystem-based management of fisheries

    Uninversion error in English-speaking children’s wh-questions: Blame it on the bigrams?

    Get PDF
    English-speaking children’s uninversion errors with wh-questions (e.g., *Who he can draw; c.f., Who can he draw?) are influenced by the surface frequency of individual bigrams and trigrams in the input, as predicted by input-based approaches. Production methods were used to elicit nonsubject wh-questions from 67 children aged 3;1 to 4;8 (M=4;0, SD=4 months). No support was found for the preregistered prediction that children will produce more uninversion errors when those errors incorporate – in the Bigram 3 position – high-frequency bigrams from uninverted structures (e.g., *Who he can draw?) than lower-frequency bigrams from uninverted structures (e.g., *Who he can name?), with all other bigram and unigram frequencies matched for each pair. However, a non-preregistered exploratory analysis found a facilitatory effect on correct-question production of the frequency of the second and third bigrams from inverted structures (e.g., can he…he draw), even after controlling for unigram frequency. This analysis also found that rates of uninversion error (e.g., *Who he can draw?) were higher when the first uninverted bigram (e.g., Who he…) is of higher frequency in the input. We conclude that while input-based accounts are correct to highlight the importance of n-gram input frequencies on rates of correct production versus uninversion error, it is unclear on current evidence which n-grams are driving errors and why. In particular, the special emphasis placed by some such accounts on n-grams at the left-edge of the utterance (e..g, Who can…) may be unwarranted
