The Kunming-Montreal Global Biodiversity Framework: what it does and does not do, and how to improve it

The Kunming-Montreal Global Biodiversity Framework (GBF) marks one of the most ambitious environmental agreements of the 21st century. Yet despite the ambition, and the considerable change in approach since negotiating its predecessor (the 2025 Vision and Aichi targets), the many pressures, including working through a global pandemic mean that the final agreement, despite several years of delay, is weaker than might have been hoped for. The GBF provides a set of four goals, composed of 23 targets (and a series of supporting annexes) which explore the options for conservation, restoration and sustainable use of biodiversity, and the mobilisation of necessary resources to maintain life on Earth. In this perspective we systematically examine the composition of the GBF, exploring what the targets lack and what weaknesses exist in text. We also detail the link between the targets and the key indicators which can be used to track success toward fulfilling the targets. We offer key recommendations which could help strengthen the application of various targets, and show where the indicators could be improved to provide more detailed information to monitor progress. Furthermore, we discuss the association between targets and their indicators, and detail where indicators may lack the necessary temporal resolution or other elements. Finally, we discuss how various actors might better prepare for the successor to the GBF in 2030 and what has been learnt about the negotiating process, including lessons to help ensure that future agreements can circumnavigate issues which may have weakened the agreement

Searching the web builds fuller picture of arachnid trade

Trade in arachnids includes millions of individuals and over 1264 species, with over 70% of individuals coming from the wild. Wildlife trade is a major driver of biodiversity loss, yet whilst the impacts of trade in some species are relatively well-known, some taxa, such as many invertebrates are often overlooked. Here we explore global patterns of trade in the arachnids, and detected 1,264 species from 66 families and 371 genera in trade. Trade in these groups exceeds millions of individuals, with 67% coming directly from the wild, and up to 99% of individuals in some genera. For popular taxa, such as tarantulas up to 50% are in trade, including 25% of species described since 2000. CITES only covers 30 (2%) of the species potentially traded. We mapped the percentage and number of species native to each country in trade. To enable sustainable trade, better data on species distributions and better conservation status assessments are needed. The disparity between trade data sources highlights the need to expand monitoring if impacts on wild populations are to be accurately gauged and the impacts of trade minimised.Peer reviewe

Developing a collaborative framework for naturalistic visual search

While much research has investigated the mechanisms of visual search behaviour in laboratory-based computer tasks, there has been relatively little work on whether these results generalise to more naturalistic search tasks and thus how well existing theories explain real-world search behaviour. In addition, work relating to this question has often been carried out by researchers working in very different disciplines, including not just vision science but also fields such as consumer behaviour, sports science and medical science, making it more difficult to get an overview of the progress made and open questions remaining. We present findings from a systematic review of real-world visual search, showing that we can group the current literature into theoretical and applied approaches, and that there are certain well-studied topics (e.g., X-ray screening) but that there are relatively few links made across different search tasks and/or search contexts. We also present preliminary work detailing our development of a “naturalistic search task battery”, which aims to provide a suite of open source, reproducible and standardised real-world search tasks, thus enabling the generation of comparable data across multiple studies and aiding theory and modelling in this area

Copper(I) complexes of P-stereogenic Josiphos and related ligands

Starting from (R)-Ugi's amine, diastereoselective lithiation followed by Ar'PCl 2 and then Ar’’MgBr led to the generation, as single diastereoisomers, of (R,S p,S phos) [Ar’=Ph, Ar’’=o-Tol] and (R,S p,R phos) [Ar’=o-Tol, Ar’’=Ph] PPFA ligand derivatives. Amine substitution of both with HPCy 2 gave P-stereogenic Josiphos ligands, and then addition of CuCl, the corresponding copper(I) complexes. The latter were also generated by using borane P and N protecting groups and in situ Cu(I) complexation, avoiding the isolation of air-sensitive phosphine intermediates. This protection methodology was also applied to the synthesis of Josiphos/CuCl complexes derived from PCl 3. In addition, related bulky cobalt-sandwich complex-based derivatives were also obtained. Preliminary investigation revealed isolated CuCl complexes as competent catalyst precursors for enantioselective conjugate addition reactions

Sustainability in a changing world: integrating human health and wellbeing, urbanisation, and ecosystem services

There is an urgent need to address interlinked sustainability issues in a world challenged by inequality, finite resources and unprecedented changes across Earth’s systems. As Future Earth Fellows, based on our collective expertise in a diverse range of sustainability issues, here we identify a specific need to recognise and respond appropriately to the nexus between human health and wellbeing, urbanisation, and ecosystem services (the ‘WUE nexus’). This nexus is a priority area for research, policy and practice. In particular, it provides a useful pathway to meet the challenges of successful implementation of the Sustainable Development Goals (SDGs). In this brief, we present the following policy recommendations:1. By emphasising urban-rural linkages, foster an integrated approach to ensure food security, food safety, and health promotion;2. Secure resilient livelihoods for all, in particular for vulnerable groups; and3. Integrate co-production of knowledge in science for decision-making, including the co-design of implementation frameworks, and the adoption of a nexus approach.<br/
