Honest advocacy for nature: presenting a persuasive narrative for conservation.

Conservation scientists are increasingly recognising the value of communicating policy-relevant knowledge to policy-makers. Whilst considerable progress has been made in offering practical advice for scientists seeking to engage more closely with decision-makers, researchers have provided few tangible examples to learn from. This paper uses an English case study, but draws out important high-level messages relevant to conservation scientists worldwide. The case study looks at how the Lawton Review presented knowledge persuasively about the suitability of England's ecological network to deal with future pressures. Through skilful framing of rigorous scientific knowledge it was able to make a significant impact on government policy. Impact was achieved through: (1) selecting politically salient frames through which to communicate; (2) using clear, accessible language, and; (3) conducting rigorous science using an authoritative team of experts. Although its publication coincided with a favourable policy window, the Lawton Review seized on this opportunity to communicate a rigorously argued, persuasive and practical conservation message; in other words, it performed 'honest advocacy'. Thus, whilst it remains important to conduct scientific research with technical rigour, conservation scientists could also benefit from identifying salient frames for conservation and communicating clearly.This work is taken from a PhD project in the Department of Geography funded by ESRC (grant number ES/I901957/1) and Homerton College (Charter Scholarship).

A Global Biological Conservation Horizon Scan of Issues for 2023

We present the results of our 14th horizon scan of issues we expect to influence biological conservation in the future. From an initial set of 102 topics, our global panel of 30 scientists and practitioners identified 15 issues we consider most urgent for societies worldwide to address. Issues are novel within biological conservation or represent a substantial positive or negative step-change at global or regional scales. Issues such as submerged artificial-light fisheries and accelerating upper ocean currents could have profound negative impacts on marine or coastal ecosystems. We also identified potentially positive technological advances, including energy production and storage, improved fertilisation methods and expansion of biodegradable materials. If effectively managed, these technologies could realise future benefits for biological diversity.This exercise was coordinated by the Cambridge Conservation Initiative and was funded by the Natural Environment Research Council and the RSPB.

A horizon scan of global biological conservation issues for 2024.

We present the results of our 15th horizon scan of novel issues that could influence biological conservation in the future. From an initial list of 96 issues, our international panel of scientists and practitioners identified 15 that we consider important for societies worldwide to track and potentially respond to. Issues are novel within conservation or represent a substantial positive or negative step-change with global or regional extents. For example, new sources of hydrogen fuel and changes in deep-sea currents may have profound impacts on marine and terrestrial ecosystems. Technological advances that may be positive include benchtop DNA printers and the industrialisation of approaches that can create high-protein food from air, potentially reducing the pressure on land for food production

The phylogenetic and geographic structure of Y-chromosome haplogroup R1a.

International audience: R1a-M420 is one of the most widely spread Y-chromosome haplogroups; however, its substructure within Europe and Asia has remained poorly characterized. Using a panel of 16 244 male subjects from 126 populations sampled across Eurasia, we identified 2923 R1a-M420 Y-chromosomes and analyzed them to a highly granular phylogeographic resolution. Whole Y-chromosome sequence analysis of eight R1a and five R1b individuals suggests a divergence time of ∼25 000 (95% CI: 21 300-29 000) years ago and a coalescence time within R1a-M417 of ∼5800 (95% CI: 4800-6800) years. The spatial frequency distributions of R1a sub-haplogroups conclusively indicate two major groups, one found primarily in Europe and the other confined to Central and South Asia. Beyond the major European versus Asian dichotomy, we describe several younger sub-haplogroups. Based on spatial distributions and diversity patterns within the R1a-M420 clade, particularly rare basal branches detected primarily within Iran and eastern Turkey, we conclude that the initial episodes of haplogroup R1a diversification likely occurred in the vicinity of present-day Iran.European Journal of Human Genetics advance online publication, 26 March 2014; doi:10.1038/ejhg.2014.50
