Wild birds have experienced unprecedented, near‐global mass mortalities since 2021, driven by outbreaks of high‐pathogenicity avian influenza virus (HPAIV) H5N1 lineage 2.3.4.4b. Managing this panzootic requires identification of transmission pathways. We investigated potential HPAIV transmission via kleptoparasitism (food theft) by examining the distribution, behaviors, and movements of two globally

Land use is both a major cause of the biodiversity crises and a potential solution to it. Decisions about land use are made in complex social–ecological systems, yet conservation research, policy, and practice often neglect the diverse and dynamic nature of land use. A deeper integration of land system science and conservation science provides major opportunities in this context, through a transfer

In many countries, complex environmental problems such as biodiversity decline are regulated at the national level by a disparate range of laws and nonstatutory policy instruments variously described by terms including plans, strategies, guidelines, statements of intent, and/or incentives. Such instruments are often grouped together by conservation policymakers and scientists under the umbrella term

Invasive species are a major cause of biodiversity loss and are notoriously expensive and challenging to manage. We developed a decision‐analytic framework for evaluating invasive species removal strategies, given objectives of maximizing eradication probability and minimizing costs. The framework uses an existing estimation model for spatially referenced removal data—one of the most accessible types

The preservation of genetic variation is fundamental in biodiversity conservation, yet its importance for population viability remains contentious. Mixed‐source reintroductions, where individuals are translocated into a single vacant habitat from multiple genetically divergent and often depauperate populations, provide an opportunity to evaluate how genetic variation and hybridization influence individual

Rigorous scientific practice relies on the tenet of transparency. However, despite regular transparency in areas such as data availability and methodological practice, the influence of personal and professional values in research design and dissemination is often not disclosed or discussed in conservation science. Conservation scientists are increasingly driven to work in collaboration with communities

Hydropower expansion is increasingly responsible for connectivity and biodiversity loss in freshwater ecosystems. The Amazon basin, which supports the highest level of freshwater biodiversity globally, faces such unplanned expansion. Here, we demonstrate and quantify the impacts of two major hydroelectric dams on the Madeira River on the trans‐Amazonian movements of one apex predatory catfish (Brachyplatystoma

The Kunming‐Montreal Global Biodiversity Framework lays out an ambitious set of goals and targets aimed at halting and reversing biodiversity loss. The extent of natural ecosystems has been selected as one of a small set of headline indicators against which countries will report progress under this framework. We evaluate the effectiveness with which this indicator is expected to capture the overall

Information about species’ locations can influence what happens to them—from supporting habitat protection to exposing poaching targets. Debate about releasing locations when new species are found highlights the trade‐off between the risk of loss and the benefits of funding and public support. No research so far has collected data on how such decisions are made, and no decision tools easily compare

There is limited quantitative evidence of the effects of socio‐economic shocks on biological resource use. Focusing on wild meat hunting, a substantial livelihood and food source in tropical regions, we evaluated the impacts of the shock from Nigeria's coronavirus disease (COVID‐19) lockdown on species exploitation around a global biodiversity hotspot. Using a 3‐year quantitative dataset collected

Protected areas have been gazetted to protect natural resources and biodiversity, but evaluations of effectiveness rarely include measures of species population change. We compiled annual site-level spending and elephant population data for 102 protected areas conserving either savannah (Loxodonta africana) or forest (Loxodonta cyclotis) elephants, which showed a median annual population decline of

The EU Biodiversity Strategy 2030 aims to better protect natural ecosystems with high biodiversity and climate change mitigation potential. To achieve this goal, it is crucial to identify forests worth protecting, such as those characterized by long continuity and old age. Here, we propose a robust approach that combines historical maps from the mid‐19th century with remote sensing data to identify

Consumer behavior change is a key priority to address the illegal wildlife trade, but evaluation of these interventions is lacking. We used surveys and randomized controlled trials to assess the effectiveness of three types of messages, which were codesigned with key stakeholders, with 2496 potential consumers and nontarget consumers in China. We found a 23% decrease in intention among potential consumers

To achieve the goals of the 2030 Global Biodiversity Framework, the European Biodiversity Strategy, and the EU Green Deal, biodiversity monitoring is critical. Monitoring efforts in Europe, however, suffer from gaps and biases in taxonomy, spatial coverage, and temporal resolution, resulting in fragmented and disconnected data. To assess user and policy needs in biodiversity monitoring, we employed

Tropical and subtropical trees provide key ecosystem services but are facing global population decline due to logging, habitat degradation, land conversion, and climate change. Vatica guangxiensis used to be a characteristic timber species of China's tropical forests but is now terminally endangered (280 individuals) and fragmented into three relictual populations in southwest China. Generating genome-wide

To ensure the protection of both people and nature, conservation practitioners have a responsibility to integrate human rights considerations into their conservation policies and practices. Here, we (i) develop a human rights-based scoring framework for international conservation organization (NGO) policy commitments and (ii) use this to conduct a gap analysis of policy commitments for nine NGOs, which

Although widely regarded as the go-to for comprehensive wildlife trade data (Eskew et al., 2020; Watters et al., 2022), short comings of the US Fish & Wildlife (USFWS) Law Enforcement Management Information System (LEMIS) have been noted for decades (GAO, 1994; Reaser & Waugh, 2007). Most recently, Weissgold (2024) recommended measures to improve LEMIS quality controls necessary for accurate scientific

The Kunming–Montreal Global Biodiversity Framework (GBF) will become the most important multilateral agreement to guide biodiversity conservation actions globally over the coming decades. An ecosystem goal and various targets for maintaining integrity, restoring degraded ecosystems, and achieving representation in conservation areas feature throughout the GBF. Here, we provide an operational framework

Coordinated policies and effective global environmental governance are needed to address the global biodiversity crisis. Human dimensions like geopolitics influence conservation decision-making and outcomes. The importance of considering these complex social factors is heightened in an era of renewed great-power politics, as the intensifying US–China rivalry has direct implications for environmental

International wildlife trade is implicitly complex and esoteric. Oftentimes, the data are doubly so, as crucial contextual information is not readily apparent. Working effectively with these data often requires a robust comprehension of international and domestic trade processes as well as their intersections with national policy administration, conservation, and ecological processes. Weissgold (2024)

Solar photovoltaic (PV) has become the second renewable energy source, giving rise to potential conflicts with biodiversity conservation. However, the information available about the impacts and mitigation measures of solar PV energy is scarce and scattered, and a rigorous and comprehensive review on the topic is lacking. Here, we review the state of knowledge on its impacts and mitigation measures

Unsustainable snaring is causing biodiversity declines across tropical protected areas, resulting in species extinctions and jeopardizing the health of forest ecosystems. Here, we used 11 years of ranger-collected data to assess the impact of intensive snare removal on snaring levels in two protected areas in Viet Nam. Snare removal resulted in significant declines in snare occupancy (36.9, 95% Bayesian

Other effective area-based conservation measures (OECMs) create opportunities for a wide range of area-based conservation strategies. As countries seek to integrate OECMs into conservation planning, it is useful to consider the types of areas that might meet the formal criteria. To support this goal, I analyzed the different types of measures discussed as possible OECMs in the literature, identifying

To achieve the goals of the Kunming–Montreal Global Biodiversity Framework (KMGBF), agreed by Parties to the Convention on Biological Diversity, there is an urgent need to address the economic drivers of biodiversity loss. The KMGBF includes a target to encourage businesses and financial institutions to disclose their impacts and dependences on biodiversity. While transparent biodiversity disclosures

Wildlife use is widespread across the world where animals and their derivates are consumed and/or traded (Ingram et al., 2021). When the use is unsustainable, it is a leading cause of biodiversity loss worldwide, with profound consequences for ecosystem services and functions (IPBES, 2022). In December 2022, Parties to the Convention on Biological Diversity adopted the Kunming–Montreal Global Biodiversity

Ecological risk assessments (ERAs) are crucial when developing national strategies to manage adverse effects from pesticide exposure to natural populations. Yet, estimating risk with surrogate species in controlled laboratory studies jeopardizes the ERA process because natural populations exhibit intraspecific variation within and across species. Here, we investigate the extent to which the ERA process

The international community set a global conservation target to protect at least 30% of the ocean by 2030 (“30 × 30”) to reverse biodiversity loss, including through marine protected areas (MPAs). However, varied MPAs result in significantly different conservation outcomes, making MPA coverage alone an inadequate metric. We used The MPA Guide framework to assess the the world's largest 100 MPAs by

Environmental losses are increasingly evoking ‘‘ecological grief’’ among environmental and conservation professionals. Ecological grief is a natural but difficult psychological experience, and a risk to well-being. Despite this, there are currently few resources available to support environmental professionals and their organizations to reduce the risks to well-being and cope effectively with ecological

Uncontrolled crossbreeding is a major challenge to the conservation of landrace horses in East Asia. Understanding the factors driving this trend is crucial for effective conservation efforts. Here, we investigate the genomic makeup of 40 Mongolian Naadam racehorses and 21 Asian landrace horse breeds through analyzing whole-genome resequencing and Y chromosome data. Our results show that crossbreeding

Forest loss and overhunting are eroding African tropical biodiversity and threatening local human food security, livelihoods, and health. Emblematic of this ecological crisis is Africa's most endangered group of monkeys, the red colobus (genus Piliocolobus). All 17 species, found in forests from Senegal in the west to the Zanzibar archipelago in the east, are threatened with extinction. Red colobus

While habitat loss is a major threat to species, the effects of habitat fragmentation independent of habitat loss (fragmentation per se) are debated. Metapopulation studies often assert negative fragmentation effects, but they do not measure fragmentation per se. We evaluate the effects of fragmentation per se (patch density) across 20 years of patch occupancy patterns of the Åland Islands Glanville

The increased availability of remote sensing products and new legislative agendas are driving a growing focus on farm-level traceability and monitoring to tackle commodity-driven deforestation. Here, we use data on land use change in Brazil (1985–2021) from Mapbiomas to demonstrate how analyses of the drivers of deforestation are sensitive to the scale of analysis: while pixel- or property-level analyses

Even after research identifies new approaches for wildlife management, translating those methods for delivery can be logistically challenging. In tropical Australia, invasive cane toads (Rhinella marina) fatally poison many anuran-eating native predators. Small-scale trials show that vulnerable predators exposed to small (nonlethal) toads can learn to delete toads from their diets, increasing survival

Numerous policy and international frameworks consider that “destructive fishing” hampers efforts to reach sustainability goals. Though ubiquitous, “destructive fishing” is undefined and therefore currently immeasurable. Here we propose a definition developed through expert consultation: “Destructive fishing is any fishing practice that causes irrecoverable habitat degradation, or which causes significant

Fungal conservation is gaining momentum globally, but many challenges remain. To advance further, more data are needed on fungal diversity across space and time. Fundamental information regarding population sizes, trends, and geographic ranges is also critical to accurately assess the extinction risk of individual species. However, obtaining these data is particularly difficult for fungi due to their

Rotational closures have potential fisheries benefits, yet their impact on coral cover is unknown. Research has shown that permanent closures can protect herbivorous fish, indirectly benefiting corals, but these observations may not apply when closed periods alternate with fishing. Here, we examine how rotational closures affect coral, focusing on systems with the potential to switch between alternative

K., Luncz, L., Ohashi, G., Pascual-Garrido, A., Piel, A., Samuni, L., Soiret, S., Sanz, C., & Koops, K. (2022). Using nonhuman culture in conservation requires careful and concerted action. Conservation Letters, e12860

Protected areas (PAs) are central to sustainability targets, yet few evaluations explore outcomes for both conservation and development, or the trade-offs involved. We applied counterfactual analyses to assess the extent to which PAs maintained forest cover and influenced well-being across >31,000 villages in Sumatra and Kalimantan, Indonesia. We examined multidimensional aspects of well-being, tracking

Conservation funding is currently limited; cost-effective conservation solutions are essential. We suggest that the thousands of field stations worldwide can play key roles at the frontline of biodiversity conservation and have high intrinsic value. We assessed field stations’ conservation return on investment and explored the impact of COVID-19. We surveyed leaders of field stations across tropical

The state of biodiversity for most of the world is largely enigmatic due to a lack of long-term population monitoring data. Citizen science programs could substantially contribute to resolving this data crisis, but there are noted concerns on whether methods can overcome the biases and imprecision inherent to aggregated opportunistic observations. We explicitly test this question by examining the temporal

Fish maw (teleost swim bladder) is a dried seafood product valued highly by Chinese cultures in East Asia, though global supply chains are poorly understood. Here, we describe the rapid development of a fish maw fishery in a low-income nation to illustrate how globalization can affect sustainability. In Papua New Guinea (PNG), fish maw developed into a fishery valued at ∼$831,000 USD annually between

International wildlife trade data are frequently used by government agencies, conservation organizations, and scientific researchers to study and protect species from overexploitation and prevent the spread of invasive species and introduction of zoonotic pathogens. Inaccurate data can lead to mistaken conclusions by researchers, the development of unsuccessful remedial conservation actions, and provide

Of the goals and targets specified by the Kunming-Montreal Global Biodiversity Framework, Target 3, often referred to as “30 × 30,” has garnered widespread attention globally. In this paper, we critique India's potential to meet this target. We find that with its vast network of ecosystems that are under some form of protection and through the recognition of other effective area-based conservation

Marine protected areas (MPAs) are a crucial component of international biodiversity conservation commitments, yet are increasingly affected by climate change. No synthesis or analysis exists of the specific on-the-ground management actions that have been taken by MPA managers in response to climate change. Here, we extract, evaluate, classify, and analyze adaptation responses from 646 existing, English-language

Coastal areas offer a diversity of habitats providing refugia and nursery for fish, promoting their biodiversity and associated contributions to people. Yet, natural coastlines are replaced by artificial infrastructures such as seaports and the influence of this artificialization on fish biodiversity remains poorly known. Here, we assessed fish biodiversity indicators using environmental DNA metabarcoding

As global tree-growing efforts have escalated in the past decade, copious failures and unintended consequences have prompted many reforestation best practices guidelines. The extent to which organizations have integrated these ecological and socioeconomic recommendations, however, remains uncertain. We reviewed websites of 99 intermediary organizations that promote and fund tree-growing projects to

Predator Free 2050 (PF2050) is a government initiative aiming to eradicate selected invasive mammals (mustelids, rats, and possums) from New Zealand (NZ) by 2050. Selecting which of 32 introduced mammal species to include has received little evaluation, yet targeting a few species often results in perverse ecological outcomes given interactions within the invasive guild. We explore how PF2050 could

A variety of criteria may influence the efficacy of networks of marine protected areas (MPA) designed to enhance biodiversity conservation and provide fisheries benefits. Meta-analyses have evaluated the influence of MPA attributes on abundance, biomass, and size structure of harvested species, reporting that MPA size, age, depth, and connectivity influence the strength of MPA responses. However, few

In 1992, the UN banned the use of large-scale pelagic driftnets on the high seas (UNGA Resolution 46/215). Three decades later, however, drift gillnets remain one of the primary fishing gears in the Indian Ocean, accounting for approximately 30% of tuna catches in this ocean. Recent estimates indicate that several million small cetaceans have been killed in Indian Ocean gillnets over the past few decades

Snakes in Africa are responsible for over 20,000 deaths annually, their indiscriminate killing. As a result, snakes are vulnerable to human population increases even at low intensities. Thus, the predicted doubling of Africa's population by 2050 is likely to pose a disproportionate threat to snakes compared to other taxa. Here we quantify the current and future overlap of snake distributions and human

Translocation is an increasingly used tool in conservation management, but there is a risk that source populations are overcollected. The risk depends critically on the detection probability and the source population size. We quantified this risk for a wingless grasshopper population in a patch of remnant habitat in suburban Melbourne that was condemned to be cleared for housing development. We collected

Areas beyond national jurisdiction, or the high seas, are vital to life on Earth. However, the conservation of these areas, for example, through area-based management tools (ABMTs), is challenging, particularly when accounting for global change. Using decision science, integrated population models, and a Critically Endangered seabird (Kuaka; Pelecanoides whenuahouensis) as a case study, we evaluated

Reeves's pheasant feathers are used to make headgears for the Chinese opera—Xiqu; however, this posed a considerable threat to the bird's population before it was banned from hunting/trade. It is unclear whether Xiqu-troupes currently use feathers from wild or captive breeding; therefore, we investigated their source and scale of feather utilization. Through interviews, we clarified the current status

The pelagic ocean is Earth's largest habitat, constituting 99% of the global biosphere by volume, directly or indirectly supporting most marine life, and supplying the majority of fish consumed by humans (Game et al., 2009; Pauly et al., 2002). However, the world's pelagic fauna is globally declining largely as a result of unsustainable fishing (Pauly & Zeller, 2016). Industrial fishing has reduced

Variation in the legal status and management of wolves (Canis lupus) across EU Member States provides a good opportunity to test the effectiveness of different practices to reduce livestock losses. This opportunity for testing is particularly useful for lethal interventions, as they are among the most controversial actions within the large carnivore management toolbox. We aimed to test a conservation
