Urban environments are dynamic landscapes shaped by a multitude of factors, including environmental conditions and socio-economic influences. This study systematically investigates how various factors shape urban plant diversity in Haikou City, Hainan Province, China, focusing on 30 key drivers including socioeconomic aspects, biophysical conditions, landscape elements, and management practices. Our research methodology involved a comprehensive analysis of these factors' impact on six types of urban plant species: spontaneous, native spontaneous, exotic spontaneous, cultivated, native cultivated, and exotic cultivated. Conducted in urban areas with varying population densities and landscape features, our sampling approach aimed to understand the species' distribution patterns. We discovered significant correlations between plant species diversity and specific environmental and socio-economic variables. Our results indicate that spontaneous species are prevalent in densely populated areas with strong social ties, whereas areas rich in tree and shrub cover see fewer such species. Native cultivated species favor more serene, less urbanized landscapes, while exotic cultivated species are predominantly found in economically affluent areas with diverse vegetation. These findings offer valuable insights for urban planning and biodiversity conservation, emphasizing the need for customized greening strategies that align with local environmental and social contexts. By adopting such tailored approaches, urban planners can more effectively manage landscapes, enrich green spaces, and foster biodiverse, sustainable ecosystems. This research not only enhances our understanding of urban plant biodiversity but also lays the groundwork for future studies and policy-making, promoting harmonious integration of diverse plant life within urban settings.

Understanding patterns of species distribution and diversity plays a vital role in biodiversity conservation. Such documentation is frequently lacking for bats, which are relatively little studied and often threatened. The Western Ghats biodiversity hotspot in peninsular India is a bat hotspot with 63 species. We conducted a comprehensive bat survey across the southern Western Ghats and used maximum entropy modeling (MaxEnt) to model the potential distribution of 37 bat species for which sufficient data were available. We generated binary maps of each species using species-specific thresholds to estimate suitable habitat areas and overlaid binary maps of species to produce bat hotspots (we use the term "bat hotspot" for regions that were suitable for more than 25 bat species). We also estimated species richness across protected area networks in the southern Western Ghats to assess the level of protection. The highest levels of species richness were found mainly along the southmost Periyar–Agastyamalai landscape. The study also identified a 1,683 km2 area of potential bat hotspot and 726 km2 (43%) of the total bat hotspots are currently within the protected area network. However, more than 50% of suitable habitats for each of the 37 species remain unprotected. Therefore, conservation decisions are needed to take into account both bat hotspots and species with restricted distributions. [ABSTRACT FROM AUTHOR]

Biodiversity science in China has seen rapid growth over recent decades, ranging from baseline biodiversity studies to understanding the processes behind evolution across dynamic regions such as the Qinghai-Tibetan Plateau. We review research, including species catalogues; biodiversity monitoring; the origins, distributions, maintenance and threats to biodiversity; biodiversity-related ecosystem function and services; and species and ecosystems' responses to global change. Next, we identify priority topics and offer suggestions and priorities for future biodiversity research in China. These priorities include (i) the ecology and biogeography of the Qinghai-Tibetan Plateau and surrounding mountains, and that of subtropical and tropical forests across China; (ii) marine and inland aquatic biodiversity; and (iii) effective conservation and management to identify and maintain synergies between biodiversity and socio-economic development to fulfil China's vision for becoming an ecological civilization. In addition, we propose three future strategies: (i) translate advanced biodiversity science into practice for biodiversity conservation; (ii) strengthen capacity building and application of advanced technologies, including high-throughput sequencing, genomics and remote sensing; and (iii) strengthen and expand international collaborations. Based on the recent rapid progress of biodiversity research, China is well positioned to become a global leader in biodiversity research in the near future. [ABSTRACT FROM AUTHOR]

Human population (often treated as overpopulation) has long been blamed as the main cause of biodiversity loss. Whilst this simplistic explanation may seem convenient, understanding the accuracy of the statement is crucial to develop effective priorities and targets to manage and reverse ongoing biodiversity loss. If untrue, the assertion may undermine practical and effective measures currently underway to counter biodiversity loss by distracting from true drivers, alienating some of the most diverse countries in the world, and failing to tackle the structural inequalities which may be behind global biodiversity declines. Through examining the drivers of biodiversity loss in highly biodiverse countries, we show that it is not population driving the loss of habitats, but rather the growth of commodities for export, particularly soybean and oil-palm, primarily for livestock feed or biofuel consumption in higher income economies. Thus, inequitable consumption drives global biodiversity loss, whilst population is used to scapegoat responsibility. Instead, the responsibilities are clear and have recently been summarized by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services IPBES: Leverage points for biodiversity conservation lie in reducing unsustainable consumption through diet shifts, tracking supply chains, and technological innovation as well as ensuring sustainable production to reduce biodiversity losses associated with industrial agriculture. • Population is often mistakenly blamed as the main driver of biodiversity loss. • However such arguments actually mis-apportion blame and hinder progress. • Consumption patterns, largely from developed economies is a major driver of biodiversity loss. • Maintaining global biodiversity will require reducing imported impacts. • Sustainable supply chains and diets are crucial to counter current trends.

The Post-2020 Global Biodiversity Framework currently is under development as part of the Convention of Biodiversity's aim to prevent global biodiversity losses by 2050, but targets can only be effectively developed and assessed if the data used for them are fit for purpose. The monitoring framework has been discussed at length and ensuring appropriate data use is critical to target effectiveness, enabling the monitoring of global biodiversity trends and assessment of target success. We outline a vision for how conservation data resources can be improved via automation and other routes to greatly enhance both ease of use and effectiveness for conservation. Synthesis across different types of data is urgently needed and could be enabled by a unified data system and automated workflows for cross-validation between data types, with downstream products such as grades for expert range maps that reflect their underlying bases and data quality and reliability to determine their fit for analysis, as well as automated preliminary IUCN assessments to expedite conservation. Capacity building and collaboration rooted in international agreements will be necessary for these initiatives to effectively function globally to enable new global targets to be achieved for effective conservation and targeted resource mobilization at all scales. • Biodiversity data underpin conservation, but they must be used more carefully. • We must build a unified data system for indexing and improving biodiversity data. • Automation throughout could greatly enhance and expedite biodiversity conservation. • International funding schemes and enhanced career recognition for data generation are needed.

In response to the global call for biodiversity conservation and sustainable development, China plans to reform its protected areas (PAs) system. Despite positive progress, there are still challenges in defining PAs boundaries, allocating management authority, and securing sustainable funding. This paper reviews the current state and challenges of China's PAs management and advocates a paradigm shift towards comprehensive public governance. This shift aligns with the Ecological Conservation Redline (ECR) and integrates PAs into the National Territorial Spatial Planning, for a coordinated layout of Ecological-Productive-Living Spaces. The current study emphasizes the need for a refined assessment of PAs, including ecosystem services, to balance human development rights and environmental sustainability. It also advocates for multi-stakeholder consultation mechanisms to ensure broader social participation, particularly for indigenous peoples and local communities. The current investigation highlights the importance of valuing ecological products to harmonize environmental protection with community welfare. This review contributes to the discourse on balancing ecological integrity with socio-economic progress and provides insights into the difference between human rights, ecological conservation, and sustainable development, marking a significant stride towards global sustainability goals.

Our 15th annual horizon scan identified 15 emerging issues of concern for global biodiversity conservation. A panel of 31 scientists and practitioners submitted a total of 96 topics that were ranked using a Delphi-style technique according to novelty and likelihood of impact on biodiversity conservation. The top 37 issues were discussed in person and online in September 2023 during which the issues were ranked according to the same criteria. Our 15 issues cover impacts from the development of new sources of hydrogen fuel to temperature changes in the mesopelagic ocean zone. Other emerging technologies include benchtop DNA printers and the creation of high-protein food from air. 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.

We present the results of our 13th annual horizon scan of issues likely to impact on biodiversity conservation. Issues are either novel within the biological conservation sector or could cause a substantial step-change in impact, either globally or regionally. Our global panel of 26 scientists and practitioners identified 15 issues that we believe to represent the highest priorities for tracking and action. Many of the issues we identified, including the impact of satellite megaconstellations and the use of long-distance wireless energy transfer, have both elements of threats and emerging opportunities. A recent state-sponsored application to commence deep-sea mining represents a significant step-change in impact. We hope that this horizon scan will increase research and policy attention on the highlighted issues. Our 13th annual horizon scan identified 15 emerging issues of concern for global biodiversity conservation. A panel of 26 scientists and practitioners submitted a total of 80 topics that were ranked using a Delphi-style technique according to the novelty and likelihood of impact on biodiversity conservation. The top 36 issues were discussed at an online meeting held in September 2021 during which issues were ranked according to the same criteria. Our 15 issues cover impacts ranging from satellite megaconstellations to deep-sea mining. Other emerging issues include floating photovoltaics, long-distance wireless energy, and ammonia as a fuel source. [ABSTRACT FROM AUTHOR]

Landscape-level conservation strategies are needed to protect the saltwater crocodile population and habitats in Myanmar. Identifying the remaining habitats and movement corridors is essential due to population decline across coastal regions and insufficient habitat coverage, even within protected areas. This study predicts the distribution of habitats and creates low-resistance corridors that facilitate movement across the landscape. Occurrence dataset encompassing a 20-year period (1999–2019) was used incorporating records gathered from the Global Biodiversity Information Facility—GBIF, crocodile counting reports from the Meinmahla Kyun wildlife sanctuary of Myanmar, and recent spotlight and camera-trap surveys. Using landscape connectivity tools, structural compositions of habitat classes were determined, and habitat patches were delineated to simulate the least-cost corridor and dispersal pathways. Two patches in Rakhine, two in Ayeyarwady and Yangon, one in Mon, and two in Tanintharyi, were identified that include 1247 km2 of core suitable habitat areas. The Ayeyarwady Delta exhibits a plethora of suitable habitats, while the Rakhine and Tanintharyi regions have higher marginal habitats that are largely unprotected. Only 12 % of the extent of occurrence of saltwater crocodiles are suitable habitats with a high potential for occupancy. Habitats are highly fragmented and four bottlenecks are identified to assist population connectivity in those fragmented patches. Despite notable challenges in ensuring connectivity to restore populations across the habitat patches, we highlighted connectivity as the foundation for establishing an ecological network of Myanmar's coastal habitats, leveraging the saltwater crocodile as an umbrella species for the region's coastal wetlands, and identifying key areas for enhanced protection. • Coastal habitats are frequently neglected in conservation planning. • Increased connectivity maybe needed for long-term viability in some species. • We identify bottlenecks for crocodile habitat connectivity in Myanmar. • Range shrinkage of saltwater crocodiles requires targeted action to counteract. • Five key coastal wetland areas are proposed for the need for critical protection.

We present the results from our 12th annual horizon scan of issues likely to impact biological conservation in the future. From a list of 97 topics, our global panel of 25 scientists and practitioners identified the top 15 issues that we believe society may urgently need to address. These issues are either novel in the biological conservation sector or represent a substantial positive or negative step-change in impact at global or regional level. Six issues, such as coral reef deoxygenation and changes in polar coastal productivity, affect marine or coastal ecosystems and seven relate to human and ecosystem-level responses to climate change. Identification of potential forthcoming issues for biological conservation may enable increased preparedness by researchers, practitioners, and decision-makers. Our 12th annual horizon scan identified 15 emerging issues of concern for global biodiversity conservation. A panel of 25 scientists and practitioners submitted a total of 97 topics that were ranked using a Delphi-style technique according to novelty and likelihood of impact on biodiversity conservation. The top 38 issues were discussed at an online meeting held in September 2020 during which issues were ranked according to the same criteria. Six of the 15 issues primarily affect marine or coastal ecosystems and seven are related to human and ecosystem-level responses to anthropogenic climate change. Other emerging issues include complete coverage of Indian states for sustainable farming and the potential for use of self-healing building materials. [ABSTRACT FROM AUTHOR]

The Belt and Road Initiative (BRI) is the largest infrastructure development in human history. Given its scale of influence and infrastructure undertakings, it is set to bring far-reaching environmental impacts to regions such as Southeast Asia, one of the biologically richest and most diverse regions in the world. Knowing where and what biodiversity BRI will potentially affect is crucial to plan and address its negative impacts. Using BRI transport infrastructure spatial data, we conducted a GIS analysis of the potential BRI impacts in Southeast Asia on terrestrial and marine biodiversity indicators, including protected areas (PAs), Key Biodiversity Areas (KBAs), terrestrial ecoregions, forest cover, threatened species, and fragile ecosystems such as seagrasses, mangroves, and coral reefs. We assessed the potential impacts across four key distance thresholds (1, 5, 25, and 50 km "impact zones") on either side of the routes. For the terrestrial routes we assessed impacts for five different types of linear rail and road infrastructure development. Within 1 km of all routes 32 PAs, 40 KBAs and 29 ecoregions are intersected. While, 142 threatened species including 26 critically endangered species are within 5 km from new rail, which are also commonly found in frontier landscapes. In marine ecosystems 20 marine PAs and 16 KBAs are intersected by BRI marine routes. We conclude by discussing ways BRI could minimise its environmental impacts and utilise its political weight to advance conservation efforts in host nations. • BRI linear infrastructure impacts on biodiversity in Southeast Asia were mapped • Impacts were assessed within four impact zone distances for road, rail and shipping • 32 PAs, 40 KBAs and 29 ecoregions are within 1 km of terrestrial routes • 26 critically endangered and species are within 5 km of new rail • Vietnam and Peninsular Malaysia land and Indonesian marine routes are of concern [ABSTRACT FROM AUTHOR]
