The power of protest in the media: examining portrayals of climate activism in UK news
Over the last several years, the United Kingdom has seen a wave of environmental movements demanding action on the climate crisis. While aligned in their goals, the groups undertaking this activism often diverge on the question of tactics. One such divergence occurred in January 2023, when Extinction Rebellion (XR) declared âWe Quitâ, ending actions that were disruptive to the general public. Peer groups Just Stop Oil and Animal Rising continued disruptive actions, viewing them as the best way to gain media coverage for their causes. Despite the urgency of addressing climate change and the growing prominence of direct action in British life, little research has examined how the news media covers and reacts to different climate actions. News media plays a vital role in influencing the publicâs perception of the climate crisis and âappropriateâ responses. We assembled a unique dataset of British news coverage of climate actions over a 7 month period, covering both before and after XRâs âWe Quitâ statement. Our results reveal that conservative publications cover climate actions more unfavorably and more inaccurately than other publications. Legal actions are generally covered more favorably than illegal ones in both conservative and non-conservative outlets and receive more coverage. Actions that target industry attract more coverage than those that target other actors, while actions that target the public are covered more favorably than those that do not. These results contribute to the scholarly debates surrounding the interaction between social movements and news media, especially on how different strategies potentially influence the extent and affective nature of coverage. They have implications for strategies adopted by climate advocates, depending on whether their goal is merely to draw attention to an issue or if it is to generate positive coverage

A scoping review into the impact of animal imagery on pro-environmental outcomes
With the recognition that most global environmental problems are a result of human actions, there is an increasing interest in approaches which have the potential to influence human behaviour. Images have a powerful role in shaping persuasive messages, yet research on the impacts of visual representations of nature is a neglected area in biodiversity conservation. We systematically screened existing studies on the use of animal imagery in conservation, identifying 37 articles. Although there is clear evidence that images of animals can have positive effects on peopleâs attitudes to animals, overall there is currently a dearth of accessible and comparable published data demonstrating the efficacy of animal imagery. Most existing studies are place and context-specific, limiting the generalisable conclusions that can be drawn. Transdisciplinary research is needed to develop a robust understanding of the contextual and cultural factors that affect how animal images can be used effectively for conservation purposes
Flagship individuals in biodiversity conservation
Flagship species are an important tool for mobilizing support for conservation. Here, we extend this concept to include individual organisms, whose characteristics, fates, and connections to people can garner public attention, attract conservation support, and spur activism. Flagship individuals typically share a similar suite of characteristics, including (1) species-level traits associated with charisma; (2) individual traits that are unique or distinctive; (3) a high degree of exposure to humans; and (4) a known, noteworthy life history or fate. The interplay between these characteristics and human agency establishes unique connections between flagship individuals and people, and generates widespread media attention. We discuss how the selection and promotion of flagship individuals can inspire empathy and, ultimately, conservation action. Finally, we identify the limitations of the flagship individual approach, while arguing that, if carefully and strategically implemented, it has the potential to produce substantial benefits for conservation policy and practice
Nature documentaries and saving nature: Reflections on the new Netflix series Our Planet
Netflix recently launched its highâprofile nature documentary Our Planet. Voiced by Sir David Attenborough in English (with Salma Hayek, Penelope Cruz and other Hollywood actors voicing versions simultaneously released in 10 other languages), Netflix are making a clear play for core BBC territory. However, they claim that this is a nature documentary with a difference as it puts the threats facing nature front and center to the narrative. We coded the scripts of Our Planet, and those of three recent Attenboroughâvoiced BBC documentaries, to explore the extent to which threats (and conservation action and success) are discussed. The only other series which comes close to the frequency with which these issues are discussed is Blue Planet II, but Our Planet is unique in weaving discussion of these issues throughout all episodes rather than keeping them to a dedicated final episode. However, although Our Planet sounds different to other documentaries, the visuals are very similar. Nature is still mostly shown as pristine, and the presence or impacts of people on the natural world very seldom appear. We discuss the potential consequences of nature documentaries erasing humans from the land/seascape. We also discuss the mechanisms by which nature documentaries may have a positive impact on conservation. Despite links between information provision and behaviour change being complex and uncertain, nature documentaries may, at least in theory, elicit change in a number of ways. They may increase willingness amongst viewers to make personal lifestyle changes, increase support for conservation organizations, and generate positive public attitudes and subsequently social norms towards an issue, making policy change more likely. Netflix is certainly bringing biodiversity and the threats it faces into the mainstream, but the mechanisms by which viewing these representations translates to concrete behaviour change are poorly understood. Increasing interest in robust impact evaluation, integrating qualitative and quantitative methods, means the time is right to explore how both showing nature on screens and talking about the threats it faces, affects people in ways which might, ultimately, contribute to saving it
A Genetic Investigation of Sex Bias in the Prevalence of Attention-Deficit/Hyperactivity Disorder
A quantitative-PCR based method to estimate ranavirus viral load following normalisation by reference to an ultraconserved vertebrate target
Ranaviruses are important pathogens of amphibians, reptiles and fish. To meet the need for an analytical method for generating normalised and comparable infection data for these diverse host species, two standard-curve based quantitative-PCR (qPCR) assays were developed enabling viral load estimation across these host groups. A viral qPCR targeting the major capsid protein (MCP) gene was developed which was specific to amphibian-associated ranaviruses with high analytical sensitivity (lower limit of detection: 4.23 plasmid standard copies per reaction) and high reproducibility across a wide dynamic range (coefficient of variation below 3.82% from 3 to 3 Ă 108 standard copies per reaction). The comparative sensitivity of the viral qPCR was 100% (n = 78) based on agreement with an established end-point PCR. Comparative specificity with the end-point PCR was also 100% (n = 94) using samples from sites with no history of ranavirus infection. To normalise viral quantities, a host qPCR was developed which targeted a single-copy, ultra-conserved non-coding element (UCNE) of vertebrates. Viral and host qPCRs were applied to track ranavirus growth in culture. The two assays offer a robust approach to viral load estimation and the host qPCR can be paired with assays targeting other pathogens to study infection burdens
Oscillatory, computational and behavioural evidence for impaired GABAergic inhibition in schizophrenia
The dysconnection hypothesis of schizophrenia (SZ) proposes that psychosis is best understood in terms of aberrant connectivity. Specifically, it suggests that dysconnectivity arises through aberrant synaptic modulation associated with deficits in GABAergic inhibition, excitationâinhibition balance and disturbances of high-frequency oscillations. Using a computational model combined with a graded-difficulty visual orientation discrimination paradigm, we demonstrate that, in SZ, perceptual performance is determined by the balance of excitationâinhibition in superficial cortical layers. Twenty-eight individuals with a DSM-IV diagnosis of SZ, and 30 age- and gender-matched healthy controls participated in a psychophysics orientation discrimination task, a visual grating magnetoencephalography (MEG) recording, and a magnetic resonance spectroscopy (MRS) scan for GABA. Using a neurophysiologically informed model, we quantified group differences in GABA, gamma measures, and the predictive validity of model parameters for orientation discrimination in the SZ group. MEG visual gamma frequency was reduced in SZ, with lower peak frequency associated with more severe negative symptoms. Orientation discrimination performance was impaired in SZ. Dynamic causal modeling of the MEG data showed that local synaptic connections were reduced in SZ and local inhibition correlated negatively with the severity of negative symptoms. The effective connectivity between inhibitory interneurons and superficial pyramidal cells predicted orientation discrimination performance within the SZ group; consistent with graded, behaviorally relevant, disease-related changes in local GABAergic connections. Occipital GABA levels were significantly reduced in SZ but did not predict behavioral performance or oscillatory measures. These findings endorse the importance, and behavioral relevance, of GABAergic synaptic disconnection in schizophrenia that underwrites excitationâinhibition balance
