Growth of non-English-language literature on biodiversity conservation

Language barriers in conservation science citation networks

Using relevant scientific evidence is crucial to effectively conserve species and ecosystems worldwide. Currently, evidence that is available only in non-English languages is severely underutilized. We examined many underutilized non-English languages in the conservation evidence literature and factors that facilitate the use of non-English-language evidence based on citation patterns of articles testing the effectiveness of conservation actions published in English and 15 non-English languages. Multivariate models incorporated explanatory variables, such as lexical distance from English, availability of an English abstract, study design complexity, conservation status of studied species, and language of citing articles. Non-English-language articles received significantly fewer English citations (i.e., citations in English-language articles) than English-language articles. Hungarian, Polish, Korean, and Russian articles were particularly undercited in English. Despite fewer English citations, many non-English-language articles had high citation rates in their own languages, indicating their value in local conservation communities. Non-English-language articles with English abstracts received more English citations. The content of the article, such as a more robust study design or assessment of threatened species, was not significantly associated with the number of English citations received. Our findings highlight the importance of increasing the visibility and recognition of non-English-language articles, especially those in currently underutilized languages, for a more comprehensive understanding of global conservation challenges. Providing a translated English abstract has the potential to increase readership of an article by increasing the accessibility to those who can understand English.

Understanding author choices in the current conservation publishing landscape

Conservation literature addresses a broad spectrum of interdisciplinary questions and benefits. Conservation science benefits most when a diverse range of authors are represented, particularly those from countries where much conservation work is focused. In other disciplines, it is well known that barriers and biases exist in the academic publishing sphere, which can affect research dissemination and an author's career development. We used a discrete choice experiment to determine how 7 journal attributes affect authors' choices of where to publish in conservation. We targeted authors directly by contacting authors published in 18 target journals and indirectly via communication channels for conservation organizations. We only included respondents who had previously published in a conservation-related journal. We used a multinomial logit model and a latent class model to investigate preferences for all respondents and distinct subpopulations. We identified 3 demographic groups across 1038 respondents (older authors from predominantly middle-income countries, younger authors from predominantly middle-income countries, and younger authors from high-income countries) who had published in conservation journals. Each group exhibited different publishing preferences. Only 2 attributes showed a consistent response across groups: cost to publish negatively affected journal choice, including authors in high-income countries, and authors had a consistent preference for double-blind review. Authors from middle-income countries were willing to pay more for society-owned journals, unlike authors from high-income countries. Journals with a broad geographical scope that were open access and that had relatively high impact factors were preferred by 2 of the 3 demographic groups. However, journal scope and open access were more important in dictating journal choice than impact factor. Overall, different demographics had different preferences for journals and were limited in their selection based on attributes such as open access policy. However, the scarcity of respondents from low-income countries (2% of respondents) highlights the pervasive barriers to representation in conservation research. We recommend journals offer double-blind review, reduce or remove open access fees, investigate options for free editorial support, and better acknowledge the value of local-scale single-species studies. Academic societies in particular must reflect on how their journals support conservation and conservation professionals.

Language barriers in conservation: consequences and solutions

Language barriers can severely hinder the advance of conservation science and its contribution to addressing the biodiversity crisis. We build a framework for understanding how language barriers can impede the evidence-based conservation of biodiversity in three ways: barriers to (i) the generation of evidence by non-native English speakers; (ii) the global synthesis of evidence scattered across different languages; and (iii) the application of English-language evidence to local decision making. We provide evidence, building on a growing body of literature, that quantifies the three consequences of language barriers in conservation. We also propose a checklist of solutions for reducing language barriers in conservation by addressing language disparities among scientists, promoting linguistic diversity in conservation, and making conservation science and its communication multilingual.

Effects of protected area coverage and research on conservation status of primates globally

Conducting conservation research and establishing protected areas (PAs) based on research results are critical to biodiversity conservation. However, the effect of research and PAs on conservation of threatened species has rarely been evaluated simultaneously. We collected data on PAs from 2000 for 2021 and determined the number of publications on global primates (published from 1950 to 2021) to assess the effect of PAs, research, and biological and socioeconomic factors on the current International Union for Conservation of Nature endangered status and change in status. We used the MCMCglmm package to conduct a phylogenetic comparative analysis to control the phylogenetic relationship of primate species. The status of 24.6% (82 of 333) of species assessed at least twice declined. Only the black lion tamarin (Leontopithecus chrysopygus) had an improved status. Species with status declines mostly occurred on the south coast of West Africa and in Madagascar. PAs covered 22.1% of each species' range. Forest loss in PAs (5.5%) was significantly lower than forest loss within 5 km outside PAs (13.8%), suggesting PAs effectively mitigated forest loss. Both the median number of total publications and conservation publications on critically endangered species were higher than those of other categories. Models showed that PA coverage and number of publications or conservation-focused publications were not related to current status or change in status over time. A decline in status was not related to creation of PAs or increase of research since the last assessment. Our results suggest that current PAs and research are not reversing the extinction crisis of global primates. Doing more conservation-oriented research, strengthening management of current PAs, and expanding PAs will be needed to protect primates globally.

The potential for AI to revolutionize conservation: a horizon scan

Artificial Intelligence (AI) is an emerging tool that could be leveraged to identify the effective conservation solutions demanded by the urgent biodiversity crisis. We present the results of our horizon scan of AI applications likely to significantly benefit biological conservation. An international panel of conservation scientists and AI experts identified 21 key ideas. These included species recognition to uncover 'dark diversity', multimodal models to improve biodiversity loss predictions, monitoring wildlife trade, and addressing human-wildlife conflict. We consider the potential negative impacts of AI adoption, such as AI colonialism and loss of essential conservation skills, and suggest how the conservation field might adapt to harness the benefits of AI while mitigating its risks.

A. Content Analysis of Digital Archives Contributes to the Historical Distribution and Folk Knowledge of the Highly Toxic Cicuta virosa L. in Hungary

The northern water hemlock is an endangered species that has been severely diminished in Hungary due to water regulation and river control in the 18th and 19th centuries. We collected data on this highly toxic plant from Hungary using archival sources, including digitized databases of daily and weekly newspapers and books. By exploring historical digital archives, we identified 88 locatable occurrence records spanning 65 flora mapping grids, 52 of which represent new additions to its known distribution. Between 1721 and 1943, a total of 103 records were found relating to its vernacular names. The most widespread names were csomorika (predominantly used in the Berettyó-Sárrét and Hortobágy regions), mételytorzsa (Rétköz, Taktaköz, Ecsedi-láp), and Kónyi gyökér (Fertő-Hanság region). Human poisonings caused by this species were primarily due to confusion with parsley, celery, and, less frequently, parsnips or carrots, occasionally resulting in the deaths of entire families. Children, in particular, were at risk when they accidentally consumed it raw as a snack. There have also been instances of intentional homicidal use and unintentional fatalities associated with its ethnomedicinal application. The plant was primarily used to treat scrofula (a form of tuberculosis-induced lymphoma) and for abortion.

How is the concept of charisma used in the academic literature about biodiversity conservation? A systematic map protocol

BACKGROUND

The extinction of species is a multifaceted phenomenon shaped by the complex interplay between biological and socio-cultural factors. Public and academic preferences for different species often play a direct or indirect role in influencing the conservation outlook of these species. The "charisma" of species and other components of biodiversity is often mentioned as an important factor in shaping human preferences, determining both the scope of scientific studies and justifications for such scope. Here, we present a protocol for systematically mapping the use of the concept of "charisma" in relation to biodiversity peer-reviewed academic literature focused on biodiversity conservation.

METHODS

The search targeting academic peer-reviewed research articles and reviews will be conducted in three publication databases, The Lens, Scopus and Web of Science (Core Collection and SciELO), and will be supplemented by search engine results from Google Scholar. Broad-scope searches will be performed in 3 different languages (English, Portuguese, and Spanish) and article screening will be performed at two stages to ensure the relevance of each entry and consistency amongst reviewers in their use of the defined inclusion criteria. The resulting systematic map of the literature will be summarised by employing a narrative synthesis approach, and through descriptive statistics and analysis of temporal trends.

Strategies for advancing inclusive biodiversity research through equitable practices and collective responsibility

Biodiversity research is essential for addressing the global biodiversity crisis, necessitating diverse participation and perspectives of researchers from a wide range of backgrounds. However, conservation faces a significant inclusivity problem because local expertise from biodiversity-rich but economically disadvantaged regions is often underrepresented. This underrepresentation is driven by linguistic bias, undervalued contributions, parachute science practices, and capacity constraints. Although fragmented solutions exist, a unified multistakeholder approach is needed to address the interconnected and systemic conservation issues. We devised a holistic framework of collective responsibility across all research participants and tailored strategies that embrace diversity and dismantle systemic barriers to equitable collaboration. This framework delineates the diverse actors and practices required for promoting inclusivity in biodiversity research, assigning clear responsibilities to researchers, publishers, institutions, and funding bodies. Strategies for researchers include cultivating self-awareness, expanding literature searches, fostering partnerships with local experts, and promoting knowledge exchange. For institutions, we recommend establishing specialized liaison roles, implementing equitable policies, allocating resources for diversity initiatives, and enhancing support for international researchers. Publishers can facilitate multilingual dissemination, remove financial barriers, establish inclusivity standards, and ensure equitable representation in peer review. Funders must remove systemic barriers, strengthen research networks, and prioritize equitable resource allocation. Implementing these stakeholder-specific strategies can help dismantle deep-rooted biases and structural inequities in biodiversity research, catalyzing a shift toward a more inclusive and representative model that amplifies diverse perspectives and maximizes collective knowledge for effective global conservation.

A protocol for harvesting biodiversity data from Facebook

The expanding use of community science platforms has led to an exponential increase in biodiversity data in global repositories. Yet, understanding of species distributions remains patchy. Biodiversity data from social media can potentially reduce the global biodiversity knowledge gap. However, practical guidelines and standardized methods for harvesting such data are nonexistent. Following data privacy and protection safeguards, we devised a standardized method for extracting species distribution records from Facebook groups that allow access to their data. It involves 3 steps: group selection, data extraction, and georeferencing the record location. We present how to structure keywords, search for species photographs, and georeference localities for such records. We further highlight some challenges users might face when extracting species distribution data from Facebook and suggest solutions. Following our proposed framework, we present a case study on Bangladesh's biodiversity-a tropical megadiverse South Asian country. We scraped nearly 45,000 unique georeferenced records across 967 species and found a median of 27 records per species. About 12% of the distribution data were for threatened species, representing 27% of all species. We also obtained data for 56 DataDeficient species for Bangladesh. If carefully harvested, social media data can significantly reduce global biodiversity knowledge gaps. Consequently, developing an automated tool to extract and interpret social media biodiversity data is a research priority.

Bird names as critical communication infrastructure in the contexts of history, language, and culture

Standardized taxonomies and lists of birds were created to improve communication. They are linguistic infrastructure-biodiversity indices and dictionaries-that have been painstakingly built and maintained and that have enhanced regional and global participation in the study and enjoyment of birds. Inclusion of people has been a core objective in creating and maintaining these standardized lists, and dissatisfaction and desires to overwrite objectionable names have been associated with them for nearly two centuries. Suggestions that bird names should be changed are continuous. Today, these suggestions include the view that some bird names must be changed to make them more accurate, inoffensive, and culturally appropriate to further increase diversity and inclusion among ornithologists and bird watchers. The latter, meritorious goal has been largely successful thus far despite many ongoing objections. Historic examples indicate that large-scale name changes, however, are not needed to accomplish major societal goals of inclusion. Some barriers to inclusion likely remain, and some changes are likely needed for English names. Often overlooked or underappreciated in name change discussions are that: 1) standardized names lists have had numerically staggering success in fostering inclusion of diverse participants globally; 2) stability is vital in such systems, and destabilization has exclusionary effects; 3) dissatisfaction with such lists and the names they include has been ongoing since these naming systems began; 4) important flexibilities exist in conjunction with these communication systems that enhance local and regional communication (e.g., alternative names in English and other languages); and 5) cultural values, important as they are, are neither universally shared nor constant, and thus risk bringing divisiveness and instability when used as a central reason for change. Consideration of standardized lists of bird names as communication systems in the fuller context of history, language, and culture will improve our management of these systems and their continued utility in fostering inclusion. With standardized, stable naming systems acting as a skeleton, proactively building outwards, both within and among languages and cultures, offers a positive and productive way to increase inclusion and to improve cultural and biodiversity conservation.

Overcoming the Tropical Andes publication divide: Insights from local researchers on challenges and solutions

The Tropical Andes, one of the world's most biodiverse regions, is vital for ecological research and conservation. However, while researchers in Bolivia, Ecuador, and Peru contribute significantly to scientific knowledge, their publication rates in academic journals have historically lagged behind neighboring nations. A multifaceted strategy was employed to understand and address the publication divide in the Tropical Andes region. This approach focused on regional researchers and consisted of a three-day workshop to improve scientific writing skills, offer publication insights, and equip researchers with tools to overcome obstacles. A series of surveys were also conducted to explore the challenges faced by local researchers and their proposed solutions, covering topics such as participant demographics, factors contributing to lower publication rates, personal barriers, proposed strategies for improving publications, specific topics of interest, participant satisfaction, most valuable workshop topics, and future recommendations. The workshop had an overwhelming response, with over 500 interested participants registering in just a few days, mostly experienced professionals, highlighting the need for such initiatives in the region. About two-thirds had ready-to-publish materials, highlighting the potential impact of targeted interventions on unlocking untapped knowledge. The surveys revealed the challenges contributing to the publication divide, including insufficient training, cultural emphasis on economic development, language barriers, limited resource access, lack of institutional support, high publishing costs, and time and financial constraints. The most common personal barriers were insufficient knowledge and experience in the publication process, lack of self-confidence, and fears of rejection. Proposed solutions include conducting training workshops, fostering collaborative networks, improving resource accessibility, and an institutional and cultural shift that encourages publishing. Addressing challenges faced by experienced professionals in the Tropical Andes by understanding individual needs, fostering support, and demystifying the publication process offers a promising path to closing the publication divide and unlocking the region's valuable scientific contributions.

Language inclusion in ecological systematic reviews and maps: Barriers and perspectives

Systematic reviews and maps are considered a reliable form of research evidence, but often neglect non-English-language literature, which can be a source of important evidence. To understand the barriers that might limit authors' ability or intent to find and include non-English-language literature, we assessed factors that may predict the inclusion of non-English-language literature in ecological systematic reviews and maps, as well as the review authors' perspectives. We assessed systematic reviews and maps published in Environmental Evidence (n = 72). We also surveyed authors from each paper (n = 32 responses), gathering information on the barriers to the inclusion of non-English language literature. 44% of the reviewed papers (32/72) excluded non-English literature from their searches and inclusions. Commonly cited reasons included constraints related to resources and time. Regression analysis revealed that reviews with larger author teams, authors from diverse countries, especially those with non-English primary languages, and teams with multilingual capabilities searched in a significantly greater number of non-English languages. Our survey exposed limited language diversity within the review teams and inadequate funding as the principal barriers to incorporating non-English language literature. To improve language inclusion and reduce bias in systematic reviews and maps, our study suggests increasing language diversity within review teams. Combining machine translation with language skills can alleviate the financial and resource burdens of translation. Funding applications could also include translation costs. Additionally, establishing language exchange systems would enable access to information in more languages. Further studies investigating language inclusion in other journals would strengthen these conclusions.

Global meta-analysis of urbanization stressors on insect abundance, richness, and traits

Anthropic stressors are among the greatest concerns in nature conservation. Among these, deforestation and urban expansion are major drivers of habitat loss, which is a major threat to biodiversity. Insects, the largest and most abundant group of animals, are declining at alarming rates. However, global estimates of the impact of anthropic stressors on insect abundance, richness, and traits are still lacking. Here, we performed a meta-analysis to estimate the impact of urbanization stressors on insect abundance, diversity, and traits. Our design focused on the effects of urbanization on moderators such as insects' activity periods, climatic zones, development stages, ecosystem, functional roles, mobility, orders, and life history. We found that insects are negatively affected by urban stressors across most moderators evaluated. Our research estimated that in insects, urbanization resulted in a mean decrease of 42 % in abundance, 40 % in richness, and 24 % in trait effects, compared to a conserved area. Even though in general there was greater loss in abundance than in richness, each moderator was affected by different means and to varying degrees, which results from artificial lighting at night as well as land use. Our study highlights the importance of promoting better protection of insect biodiversity in the future from the enormous loss in biodiversity reported in >500 papers assessed.

Revegetation through seeding or planting: A worldwide systematic map

Roughly 2 billion ha of land are degraded and in need of ecological restoration worldwide. Active restoration frequently involves revegetation, which leads to the dilemma of whether to conduct direct seeding or to plant nursery-grown seedlings. The choice of revegetation method can regulate plant survival and performance, with economic implications that ultimately feed back to our capacity to conduct restoration. We followed a peer-reviewed protocol to develop a systematic map that collates, describes and catalogues the available studies on how seeding compares to planting in achieving restoration targets. We compiled a database with the characteristics of all retrieved studies, which can be searched to identify studies of particular locations and habitats, objectives of restoration, plant material, technical aspects, and outcomes measured. The search was made in eight languages and retrieved 3355 publications, of which 178 were retained. The systematic map identifies research gaps, such as a lack of studies in the global South, in tropical rainforests, and covering a long time period, which represent opportunities to expand field-based research. Additionally, many studies overlooked reporting on important technical aspects such as seed provenance and nursery cultivation methods, and others such as watering or seedling protection were more frequently applied for planting than for seeding, which limits our capacity to learn from past research. Most studies measured outcomes related to the target plants but avoided measuring general restoration outcomes or economic aspects. This represents a relevant gap in research, as the choice of revegetation method is greatly based on economic aspects and the achievement of restoration goals goes beyond the establishment of plants. Finally, we identified a substantial volume of studies conducted in temperate regions and over short periods (0-5 y). This research cluster calls for a future in-depth synthesis, potentially through meta-analysis, to reveal the overall balance between seeding and planting and assess whether the response to this question is mediated by species traits, environmental characteristics, or technical aspects. Besides identifying research clusters and gaps, the systematic map database allows managers to find the most relevant scientific literature on the appropriateness of seeding vs. planting for particular conditions, such as certain species or habitats.

Insights into the coexistence of birds and humans in cropland through meta-analyses of bird exclosure studies, crop loss mitigation experiments, and social surveys

Birds share lands with humans at a substantial scale and affect crops. Yet, at a global scale, systematic evaluations of human-bird coexistence in croplands are scarce. Here, we compiled and used meta-analysis approaches to synthesize multiple global datasets of ecological and social dimensions to understand this complex coexistence system. Our result shows that birds usually increase woody, but not herbaceous, crop production, implying that crop loss mitigation efforts are critical for a better coexistence. We reveal that many nonlethal technical measures are more effective in reducing crop loss, e.g., using scaring devices and changing sow practices, than other available methods. Besides, we find that stakeholders from low-income countries are more likely to perceive the crop losses caused by birds and are less positive toward birds than those from high-income ones. Based on our evidence, we identified potential regional clusters, particularly in tropical areas, for implementing win-win coexistence strategies. Overall, we provide an evidence-based knowledge flow and solutions for stakeholders to integrate the conservation and management of birds in croplands.

Language Barriers in Organismal Biology: What Can Journals Do Better?

In the field of organismal biology, as in much of academia, there is a strong incentive to publish in internationally recognized, highly regarded, English-language journals to promote career advancement. This expectation has created a linguistic hegemony in scientific publishing, whereby scholars for whom English is an additional language face additional barriers to achieving the same scientific recognition as scholars who speak English as a first language. Here, we surveyed the author guidelines of 230 journals in organismal biology with impact factors of 1.5 or greater for linguistically inclusive and equitable practices and policies. We looked for efforts that reflect first steps toward reducing barriers to publication for authors globally, including the presence of statements that encouraged submissions from authors of diverse nationalities and backgrounds, policies regarding manuscript rejection based on perceived inadequacies of the English language, the existence of bias-conscious reviewer practices, whether translation and editing resources or services are available, allowance for non-English abstracts, summaries, or translations, and whether journals offer license options that would permit authors (or other scholars) to translate their work and publish it elsewhere. We also directly contacted a subset of journals to verify whether the information on their author guidelines page accurately reflects their policies and the accommodations they would make. We reveal that journals and publishers have made little progress toward beginning to recognize or reduce language barriers. Counter to our predictions, journals associated with scientific societies did not appear to have more inclusive policies compared to non-society journals. Many policies lacked transparency and clarity, which can generate uncertainty, result in avoidable manuscript rejections, and necessitate additional time and effort from both prospective authors and journal editors. We highlight examples of equitable policies and summarize actions that journals can take to begin to alleviate barriers to scientific publishing.

Aliens in caves: the global dimension of biological invasions in subterranean ecosystems

Alien species are a significant threat to natural ecosystems and human economies. Despite global efforts to address this challenge, the documented number of alien species is rapidly increasing worldwide. However, the magnitude of the impact of alien species may vary significantly across habitats. For example, some habitats are naturally less prone to biological invasions due to stringent abiotic and biotic characteristics, selecting for a limited number of introduced species possessing traits closely related to the native organisms. Subterranean ecosystems are quintessential examples of habitats with strong environmental filters (e.g. lack of light and scarcity of food), driving convergent adaptations in species that have successfully adapted to life in darkness. Despite these stringent environmental constraints, the number of records of alien species in subterranean ecosystems has increased in recent decades, but the relevant literature remains largely fragmented and mostly anecdotal. Therefore, even though caves are generally considered very fragile ecosystems, their susceptibility to impacts by alien species remains untested other than for some very specific cases. We provide the first systematic literature survey to synthesise available knowledge on alien species in subterranean ecosystems globally. This review is supported by a database summarising the available literature, aiming to identify gaps in the distribution and spread of alien invertebrate species in subterranean habitats, and laying the foundations for future management practices and interventions. First, we quantitatively assessed the current knowledge of alien species in subterranean ecosystems to shed light on broader questions about taxonomic biases, geographical patterns, modes of dispersal, pathways for introductions and potential impacts. Secondly, we collected species-specific traits for each recorded alien species and tested whether subterranean habitats act as ecological filters for their establishment, favouring organisms with pre-adaptive traits suitable for subterranean life. We found information on the presence of 246 subterranean alien species belonging to 18 different classes. The dominant alien species were invertebrates, especially insects and arachnids. Most species were reported in terrestrial subterranean habitats from all continents except Antarctica. Palaearctic and Nearctic biogeographic regions represented the main source of alien species. The main routes of introductions into the recipient country are linked to commercial activities (84.3% of cases for which there was information available). Negative impacts have been documented for a small number of case studies (22.7%), mostly related to increased competition with native species. For a limited number of case studies (6.1%), management strategies were reported but the effectiveness of these interventions has rarely been quantified. Accordingly, information on costs is very limited. Approximately half of the species in our database can be considered established in subterranean habitats. According to our results, the presence of suitable traits grants access to the stringent environmental filter posed by subterranean environments, facilitating establishment in the new habitat. We recommend that future studies deepen the understanding of invasiveness into subterranean habitats, raising public and scientific community awareness of preserving these fragile ecosystems.
