Overview of SnakeCLEF 2022: Automated Snake Species Identification on a Global Scale

The main goal of the third year of the SnakeCLEF challenge was to provide an evaluation platform that helps track the performance of AI-driven methods for snake species recognition systems on a global scale and allows direct comparison with human experts. We ran two challenges separately for humans — experts and novices — and AI methods in order to lay the groundwork for future comparison between human and machine-based snake species identification. We have provided 187,129 snake observations with 318,532 photographs — 270,251 for training and 48,281 for testing — of 1,572 snake species collected in 208 countries. The human performance evaluation was conducted on a tailored subset with 150 images derived from the full test set. We report (i) a description of the provided data, (ii) evaluation methodology and principles, (iii) an overview of the methods submitted by the participating teams, and (iv) a discussion of the obtained results. © 2022 Copyright for this paper by its authors

Understanding and tackling snakebite envenoming with transdisciplinary research

Snakebite envenoming (SBE) is a neglected tropical disease (NTD) of high global impact. The World Health Organization (WHO) estimates 4.5 to 5.4 million people are bitten by snakes annually, resulting in 1.8 to 2.7 million envenomings, 81,000 to 138,000 deaths, and at least 400,000 people suffering from physical or psychological sequelae. SBE mostly affects impoverished rural populations in sub-Saharan Africa, Asia, Latin America, and parts of Oceania, thus fueling a vicious cycle of poverty and illness. SBE not only affects humans, but also domestic animals, including livestock, with negative social and economic consequences. This requires a better understanding of the complex social, cultural, and ecological contexts where SBE occurs, within the conceptual frame of One Health, an integrated approach that recognizes the health of humans, animals, and the environment as closely linked and interdependent. Such complexity demands more integrative approaches for better understanding and confronting this disease. SBE has unique features that make its prevention and control challenging. Unlike many infectious diseases, SBE cannot be eradicated, but its incidence and impact can be reduced through effective programs aimed at better prevention and rapid access to treatment. This in turn demands the engagement of communities to improve the cohabitation of humans, domestic animals, and snakes in rural agroecosystems. In 2019, the WHO launched a strategy for the prevention and control of SBE, aimed at halving the deaths and disabilities caused by this NTD by the year 2030. This strategy is based on 4 pillars, i.e., empower and engage communities; ensure safe, effective treatment; strengthen health systems; and increase partnerships, coordination, and resources. Building on previous ideas and publications, this article discusses and advocates for transdisciplinary research on SBE and for promoting dialogue and collaboration between sectors, particularly by engaging communities affected by SBE at all levels of the research process

Crowdsourcing snake identification with online communities of professional herpetologists and avocational snake enthusiasts

Species identification can be challenging for biologists, healthcare practitioners and members of the general public. Snakes are no exception, and the potential medical consequences of venomous snake misidentification can be significant. Here, we collected data on identification of 100 snake species by building a week-long online citizen science challenge which attracted more than 1000 participants from around the world. We show that a large community including both professional herpetologists and skilled avocational snake enthusiasts with the potential to quickly (less than 2 min) and accurately (69–90%; see text) identify snakes is active online around the clock, but that only a small fraction of community members are proficient at identifying snakes to the species level, even when provided with the snake's geographical origin. Nevertheless, participants showed great enthusiasm and engagement, and our study provides evidence that innovative citizen science/crowdsourcing approaches can play significant roles in training and building capacity. Although identification by an expert familiar with the local snake fauna will always be the gold standard, we suggest that healthcare workers, clinicians, epidemiologists and other parties interested in snakebite could become more connected to these communities, and that professional herpetologists and skilled avocational snake enthusiasts could organize ways to help connect medical professionals to crowdsourcing platforms. Involving skilled avocational snake enthusiasts in decision making could build the capacity of healthcare workers to identify snakes more quickly, specifically and accurately, and ultimately improve snakebite treatment data and outcomes

Citizen science and online data: Opportunities and challenges for snake ecology and action against snakebite

The secretive behavior and life history of snakes makes studying their biology, distribution, and the epidemiology of venomous snakebite challenging. One of the most useful, most versatile, and easiest to collect types of biological data are photographs, particularly those that are connected with geographic location and date-time metadata. Photos verify occurrence records, provide data on phenotypes and ecology, and are often used to illustrate new species descriptions, field guides and identification keys, as well as in training humans and computer vision algorithms to identify snakes. We scoured eleven online and two offline sources of snake photos in an attempt to collect as many photos of as many snake species as possible, and attempt to explain some of the inter-species variation in photograph quantity among global regions and taxonomic groups, and with regard to medical importance, human population density, and range size. We collected a total of 725,565 photos—between 1 and 48,696 photos of 3098 of the world's 3879 snake species (79.9%), leaving 781 “most wanted” species with no photos (20.1% of all currently-described species as of the December 2020 release of The Reptile Database). We provide a list of most wanted species sortable by family, continent, authority, and medical importance, and encourage snake photographers worldwide to submit photos and associated metadata, particularly of “missing” species, to the most permanent and useful online archives: The Reptile Database, iNaturalist, and HerpMapper.ISSN:2590-171

Climate change and One Health

The journal The Lancet recently published a countdown on health and climate change. Attention was focused solely on humans. However, animals, including wildlife, livestock and pets, may also be impacted by climate change. Complementary to the high relevance of awareness rising for protecting humans against climate change, here we present a One Health approach, which aims at the simultaneous protection of humans, animals and the environment from climate change impacts (climate change adaptation). We postulate that integrated approaches save human and animal lives and reduce costs when compared to public and animal health sectors working separately. A One Health approach to climate change adaptation may significantly contribute to food security with emphasis on animal source foods, extensive livestock systems, particularly ruminant livestock, environmental sanitation, and steps towards regional and global integrated syndromic surveillance and response systems. The cost of outbreaks of emerging vector-borne zoonotic pathogens may be much lower if they are detected early in the vector or in livestock rather than later in humans. Therefore, integrated community-based surveillance of zoonoses is a promising avenue to reduce health effects of climate change

Precision global health : a roadmap for augmented action

With increased complexity in various global health challenges comes a need for increased precision and the adoption of more tailored health interventions. Building on precision public health, we propose precision global health (PGH), an approach that leverages life sciences, social sciences, and data sciences, augmented with artificial intelligence (AI), in order to identify transnational problems and deliver targeted and impactful interventions through integrated and participatory approaches. With more than four billion Internet users across the globe and the accelerating power of AI, PGH taps on our current augmented capacity to collect, integrate, analyse and visualise large volumes of data, both non-specific and specific to health. With the support of governments and donors, and together with international and non-governmental organisations, universities and research institutions can generate innovative solutions to improve health and wellbeing of the most vulnerable populations around the world. In line with the Sustainable Development Goals, we propose here a road map for the development and implementation of PGH.https://jphe.amegroups.compm2021Immunolog

Semi-Structured File Analysis for Information Integration

This paper describes a PostScript file analyzer for extracting information from Web PostScript documents. Our motivation for studying this problem is the building of an information- integration system. The information extracted from these semi-structured files can be used to model the contents of Web information sources and to define semantic links between items of information. Extracted information can be integrated to other information coming from different sites. We have demonstrated this analyzer by an operational prototype system. Key words: World Wide Web, information source, semi-structured data file, PostScript analyzer, information integration. 2.1 Introduction The World Wide Web (WWW) is an ever-expanding global information resource. Despite the general availability of information, it is difficult for a user to locate relevant pieces of information and to integrate them. To overcome these problems, several solutions have been proposed recently, which mainly rely on two res..
