Determining a welfare prioritization for horses using a Delphi method

Equine welfare issues are receiving increasing attention in the UK, but welfare problems can arise from a wide range of causes. In order to identify the most important welfare concerns for horses, we used a Delphi method with 19 equine welfare experts. An initial list of 84 equine welfare issues was generated using an online discussion board and NVivo thematic analysis. Subsequently, experts ranked these welfare issues for perceived prevalence, severity and duration of suffering associated with each issue on a 6-point Likert scale. All issues with a mean score of 3 or above (n = 37) were included in subsequent rounds. Finally, a subset of experts attended a two-day workshop to determine the final priority list of welfare issues. The welfare issues perceived to be most prevalent were lack of biosecurity, delayed euthanasia, lack of owner knowledge of equine welfare needs, fear and stress from use, and obesity. The issues considered to cause greatest suffering for individual horses were delayed euthanasia, lack of recognition by owners of pain behaviour, large worm burdens, obesity and being fed unsuitable diets for equine feeding behaviour. These outcomes can help to focus research and education interventions on the most pressing welfare issues for horses

The Welfare of Traveller and Gypsy Owned Horses in the UK and Ireland

SIMPLE SUMMARY: Travellers and Gypsies are recognised ethnic groups in the UK and Ireland. Horse ownership is an important part of their lives; however, poor horse welfare is often perceived to be associated with these horse-owning communities. Nevertheless, studies on the welfare of Traveller and Gypsy-owned horses are lacking. The welfare of 104 horses in the UK and Ireland was evaluated using a horse welfare protocol that assessed health conditions, resource provision, management and horse behaviour. In order to potentially understand how a horse was feeling, Qualitative Behaviour Assessment (QBA) was used to evaluate their body language. Most horses were found to have good body condition, a healthy coat and few skin problems or joint issues, however, 27% of horses were found to have neglected hooves. In the voluntary animal approach test, most horses showed a friendly response. Positive QBA terms were more prevalent than negative terms, therefore, the emotional state of Traveller and Gypsy owned horses was deemed to be positive overall. An association between QBA and various horse welfare measures was identified, e.g., improved mood was associated with better water availability. Findings in this study did not support previous negative perceptions of horse welfare in Traveller and Gypsy horse owning communities. ABSTRACT: Travellers and Gypsies are recognised ethnic groups in the UK and Ireland. Horse ownership is an important cultural tradition, however, practices associated with poor welfare are often perceived to be linked to these horse owning communities. Despite this, empirical studies on the welfare status of Traveller and Gypsy owned horses are lacking. To determine the welfare status of Traveller and Gypsy owned horses, 104 horses were assessed using a bespoke horse welfare protocol. This protocol assessed animal, resource and management-based measures. In addition, Qualitative Behaviour Assessment (QBA) identified horses’ emotional state. Results indicated that 81% of horses had an optimal body condition score, with no horse recorded as very thin/fat. The absence of limb conditions (95%), ocular (98%) and nasal (93%) discharges were evident in most horses, and 81% of horses responded positively to the voluntary animal approach test. The most commonly observed welfare issues were hoof neglect (27%), with hoof cracks/breakages (19%) being the most prevalent. QBA indicated that positive emotional states were more commonplace than negative. A relationship between QBA and other horse welfare measures was observed, e.g., improved mood was associated with better water availability. This research provides novel data in the under-researched area of the welfare of Traveller and Gypsy owned horses and counters perceptions of a poor welfare state in this group of horses

Trade-offs and Optimisation of Land-Use for Pastoralism and Carbon in Southeastern Australia

Globally, pressure to ensure future food security is being challenged by competing needs for multiple land-uses in agricultural systems. Rangelands are both a source of greenhouse gas emissions as well as providing opportunities for emissions reduction. Carbon farming is a new land-use option that sequesters carbon in vegetation and soils. National incentive programs in Australia for this option have resulted in significant recent land-use change across Australian rangelands. Beyond the mitigation benefits, the potential for carbon farming income to enhance socio-ecological resilience in rangelands has been identified. However, there are major uncertainties about the impacts of climate change on sequestration rates and trade-offs between land-use for carbon and pastoral production. The AUD$2.45 billion Commonwealth Emissions Reduction Fund has driven recent land-use change and a further AUD$2 billion over the next 10 years, coupled with a fast-growing secondary carbon market is continuing to drive demand for carbon credits. The ability to supply these carbon credits and meet international emissions reduction obligations but limit the trade-offs with pastoral production can be supported through an identification of spatial prioritisation and optimisation at a landscape scale. We use a case study of New South Wales where ~3 million ha of traditional rangeland pastoralism is currently delivering ~27% of the national land sector abatement. Priority areas and optimisation of land-use for carbon farming and production under current and future climates were determined by developing a Carbon Optimisation Model (COM). This high-resolution integrated environmental-economic model provides predictions of spatiotemporal dynamics of land-use options for variations of incentive payment levels and policy settings. Regional downscaling of an ensemble of global circulation models (GCMs) were used to predict the climate impacts on future sequestration rates derived from 3PG forest growth model to quantify carbon supply under future climates. The COM can be used to produce spatial maps to underpin strategic prioritisation abatement activities and allow abatement opportunities to be incorporated into regional NRM planning

Health and Climate–Needs

This paper describes the needs for climate risk management and information services for the health sector to serve research, educational and operational needs of ministries of health and their partners, those agencies that support broader public health service provision as well as respond to epidemics and emergencies. While climate information is considered highly relevant to helping guide improvements in public health provision, to date this information is largely underutilized. We explore some of the gaps in satisfying these needs, and we make recommendations to help fill the identified gaps

Polls and the political process: the use of opinion polls by political parties and mass media organizations in European post‐communist societies (1990–95)

Opinion polling occupies a significant role within the political process of most liberal-capitalist societies, where it is used by governments, parties and the mass media alike. This paper examines the extent to which polls are used for the same purposes in the post-communist countries of Central and Eastern Europe, and in particular, for bringing political elites and citizens together. It argues that these political elites are more concerned with using opinion polls for gaining competitive advantage over their rivals and for reaffirming their political power, than for devolving political power to citizens and improving the general processes of democratization

Mechanism of age-dependent susceptibility and novel treatment strategy in glutaric acidemia type I

Glutaric acidemia type I (GA-I) is an inherited disorder of lysine and tryptophan metabolism presenting with striatal lesions anatomically and symptomatically similar to Huntington disease. Affected children commonly suffer acute brain injury in the context of a catabolic state associated with nonspecific illness. The mechanisms underlying injury and age-dependent susceptibility have been unknown, and lack of a diagnostic marker heralding brain injury has impeded intervention efforts. Using a mouse model of GA-I, we show that pathologic events began in the neuronal compartment while enhanced lysine accumulation in the immature brain allowed increased glutaric acid production resulting in age-dependent injury. Glutamate and GABA depletion correlated with brain glutaric acid accumulation and could be monitored in vivo by proton nuclear magnetic resonance (1H NMR) spectroscopy as a diagnostic marker. Blocking brain lysine uptake reduced glutaric acid levels and brain injury. These findings provide what we believe are new monitoring and treatment strategies that may translate for use in human GA-I

RNA sequencing reveals MMP2 and TGFB1 downregulation in LRRK2 G2019S Parkinson's iPSC-derived astrocytes

Non-neuronal cell types such as astrocytes can contribute to Parkinson's disease (PD) pathology. The G2019S mutation in leucine-rich repeat kinase 2 (LRRK2) is one of the most common known causes of familial PD. To characterize its effect on astrocytes, we developed a protocol to produce midbrain-patterned astrocytes from human induced pluripotent stem cells (iPSCs) derived from PD LRRK2 G2019S patients and healthy controls. RNA sequencing analysis revealed the downregulation of genes involved in the extracellular matrix in PD cases. In particular, transforming growth factor beta 1 (TGFB1), which has been shown to inhibit microglial inflammatory response in a rat model of PD, and matrix metallopeptidase 2 (MMP2), which has been shown to degrade α-synuclein aggregates, were found to be down-regulated in LRRK2 G2019S astrocytes. Our findings suggest that midbrain astrocytes carrying the LRRK2 G2019S mutation may have reduced neuroprotective capacity and may contribute to the development of PD pathology

LSST: from Science Drivers to Reference Design and Anticipated Data Products

(Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a single wide-deep-fast sky survey, and LSST will have unique survey capability in the faint time domain. The LSST design is driven by four main science themes: probing dark energy and dark matter, taking an inventory of the Solar System, exploring the transient optical sky, and mapping the Milky Way. LSST will be a wide-field ground-based system sited at Cerro Pach\'{o}n in northern Chile. The telescope will have an 8.4 m (6.5 m effective) primary mirror, a 9.6 deg$^2$ field of view, and a 3.2 Gigapixel camera. The standard observing sequence will consist of pairs of 15-second exposures in a given field, with two such visits in each pointing in a given night. With these repeats, the LSST system is capable of imaging about 10,000 square degrees of sky in a single filter in three nights. The typical 5$\sigma$ point-source depth in a single visit in $r$ will be $\sim 24.5$ (AB). The project is in the construction phase and will begin regular survey operations by 2022. The survey area will be contained within 30,000 deg$^2$ with $\delta<+34.5^\circ$, and will be imaged multiple times in six bands, $ugrizy$, covering the wavelength range 320--1050 nm. About 90\% of the observing time will be devoted to a deep-wide-fast survey mode which will uniformly observe a 18,000 deg$^2$ region about 800 times (summed over all six bands) during the anticipated 10 years of operations, and yield a coadded map to $r\sim27.5$. The remaining 10\% of the observing time will be allocated to projects such as a Very Deep and Fast time domain survey. The goal is to make LSST data products, including a relational database of about 32 trillion observations of 40 billion objects, available to the public and scientists around the world.Comment: 57 pages, 32 color figures, version with high-resolution figures available from https://www.lsst.org/overvie
