It’s possible that I shall make an ass of myself. But in that case one can always get out of it with a little dialectic. I have, of course, so worded my proposition as to be right either way (K.Marx, Letter to F.Engels on the Indian Mutiny)

Uncertainty in measuring biodiversity change could hinder progress towards global targets for nature
Researchers find it could be difficult to detect biodiversity improvements due to conservation action for nature and suggest practical solutions to guide conservation
More than ever before, there is a growing interest in dedicating resources to stop the loss of biodiversity, as recently exemplified by the Kunming-Montreal Global Biodiversity Framework (GBF) decided at COP15 in December 2022. The GBF focuses on understanding why biodiversity is declining and what actions are needed to reverse this trend. However, according to researchers at McGill University, implementing the plan is challenging because information about biodiversity changes is not evenly available everywhere, and is uncertain in many places.
With the available data, can the scientific community and policymakers truly know if they are making progress toward international biodiversity targets, even if their efforts were effective? The research says that without a better picture of how and why biodiversity is changing in most countries, it is difficult to evaluate the effect of national plans outlined in the GBF.
“Even if policies stopped the decline of animal populations, we show mathematically that it will be hard to detect improvements with high certainty, in many places for various types of species (48 of 62 countries and species groups),” explains Prof. Brian Leung from McGill’s Department of Biology and Bieler School of Environment and lead author of the study. “This is because detecting progress is limited by the current levels of uncertainty in the data (the records are either too sparse or too variable) describing animal population trends”.
To further this point, co-author Prof. Andrew Gonzalez compares this issue with monitoring recovery in heart health after an illness. “This would not be easy to do if a doctor had not kept good historical records about a person’s heart health and without good past records, it would be difficult to know if the heart is recovering because of the treatment it is receiving. Now, imagine trying to detect if heart health was improving on average across all Canadians (perhaps by following government recommendations on diet) if data on national heart health was not collected in the past or measured into the future.”
Prof. Gonzalez continues: “instead of heart health we assessed the health of animal populations - how fast they are declining or recovering – and whether we can conclude if populations are recovering worldwide. Tracking biodiversity targets and evaluating progress cannot be done well without filling the gaps in the information at hand and reducing the uncertainty that hinders our ability to evaluate if current trends are improving.”
Measuring efforts across the board
In light of these findings, how should the scientific community and policy makers evaluate their efforts to meet such ambitious goals like preserving 30% of land and water by 2030 and slowing the rate of human-caused species extinctions? The researchers make several suggestions, including proposing a risk framework that would establish unacceptable thresholds for biodiversity decline, which are easier to detect. Also, the authors suggest investment in a national and international biodiversity monitoring systems to improve trend estimates worldwide.
As Prof. Leung concludes: “Our results highlight that care must be taken to structure how we gather knowledge about biodiversity, so that we will be able to report whether we have succeeded in meeting our global targets given international investment in nature conservation or alternatively, whether we need to re-orient our actions.”
In summary, these recommendations put forward a more rigorous approach to interpreting biodiversity trends, incorporating risk considerations, boosting investment in monitoring, explicitly deciding thresholds for success, and the use of reference benchmarks to make informed conservation decisions. If implemented, many countries potentially could benefit, given the international reach of the GBF.
Conservationists have initiated breeding programs in Vietnam to recover spotted softshell turtle populations threatened by overconsumption and habitat loss.
Based on a literature study, field surveys across Vietnam, and genetic screenings of collected samples, researchers estimated the range and conservation status of Pelodiscus variegatus, the spotted softshell turtle. The data were then used to model the species’ potential range in Vietnam.
Alarmingly, although several protected areas in Vietnam appear to harbour suitable habitats for the species, no populations were identified in any of the sites, indicating it is especially susceptible to extinction.
To recover natural populations of the species, the Institute of Ecology and Biological Resources and Cologne Zoo, Germany, initiated an in-country breeding program. In late 2023, they released 50 young and healthy turtles to a site with suitable climate and habitat in northern Vietnam.
It is hoped that additional individuals will be reintroduced to protected areas in north-central Vietnam, the sanctuary of spotted softshell turtles, to reverse its declining trend and further contribute to the global Reverse the Red movement, a target best accomplished by applying the IUCN’s One Plan Approach to Conservation.
Softshell turtles of the genus Pelodiscus are broadly distributed from southeastern Siberia through China to Vietnam. However, their range is currently extended to Indonesia, northern Australia, western Europe, North America, Hawaii, and Mauritius as a result of human transportation and breeding activities.
The turtles are considered a delicacy in China and some Southeast Asian countries. In China alone, each year hundreds of million turtles are traded, making them the most widely consumed turtles in the world.
Traditionally, this genus had been considered monotypic with only one recognised species, the Chinese softshell turtle (Pelodiscus sinensis). However, recent research has shown that the genus is much more diverse with at least seven species known to science.
Due to their morphological similarity, widespread farming activities, overharvesting, and their aquatic lifestyle, it is often difficult to study them in their natural habitat to better understand their distribution as well as their population and conservation status.
Like other congeners, the spotted softshell turtle is facing tremendous threats, from habitat loss to overharvesting for food and genetic pollution because the Chinese softshell turtle has been farmed across the country, imperilling the native genetic sources.
As the result, the Turtle Taxonomy Working Group, the global authority on taxonomic and conservation status of turtles worldwide, provisionally classifies the species as Critically Endangered, the highest ranking for taxa most vulnerable to extinction.

THE BICIKL CONSORTIUM GATHERED IN CAMBRIDGE (UNITED KINGDOM) AND ON ZOOM FOR THE FINAL GENERAL ASSEMBLY OF THE HORIZON 2020-FUNDED PROJECT ALMOST THREE YEARS AFTER ITS LAUNCH.
The city of Cambridge and the Wellcome Campus hosted the Final General Assembly of the EU-funded project BiCIKL (acronym for Biodiversity Community Integrated Knowledge Library): a 36-month endeavour that saw 14 member institutions and 15 research infrastructures representing diverse actors from the biodiversity data realm come together to improve bi-directional links between different platforms, standards, formats and scientific fields. Consortium members who could not attend the meeting in Cambridge joined the meeting remotely.
After a welcome cocktail reception on Monday evening at Hilton Cambridge City Centre, on Tuesday, the consortium made an early start with a recap of BiCIKL’s key milestones and outputs from the last three years. All Work Package leaders had their own timeslot to discuss the results of their collaborations.
They all agreed that the Biodiversity Knowledge Hub - the one-stop portal for understanding the complex - yet increasingly interconnected landscape of biodiversity research infrastructures - is likely the flagship outcome of BiCIKL.
In the afternoon, the participants focused on the services developed under BiCIKL. Amongst the many services resulting from the project some were not originally planned. Rather those were the ‘natural’ products of the dialogue and collaboration that flourished within the consortium throughout the project. “A symptom of passion,” said Prof. Lyubomir Penev, project coordinator of BiCIKL and founder/CEO of Pensoft Publishers.
An excellent example of one such service is what the partners call the “Biodiversity PMC”, which brings together biodiversity literature from thousands of scholarly journals and over 500,000 taxonomic treatments, in addition to the biomedical content available from NIH’s PubMed Central, into the SIB Literature Services (SIBiLS) database. What’s more, users at SIBiLS - be it human or AI - can now use advanced text- and data-mining tools, including AI-powered factoid question-answering capacities, to query all this full-text indexed content and seek out, for example, species traits and biotic interactions. Read more about the “Biodiversity PMC” in its recent official announcement.
Far from being the only one, the “Biodiversity PMC” is in good company: from the blockchain-based technology of LifeBlock to the curation of the DNA sequences by PlutoF, the BiCIKL project consortium takes pride in having developed twelve services dedicated to FAIR and linked ready-to-use biodiversity data.
On Wednesday, the consortium focused on BiCIKL's activities from the Transnational and Virtual Access Pillar, which included both presentations by each open call leader and VA leader, as well as open discussions and a recap of what the teams have learnt from these experiences.
Thursday was dedicated to an open event where BiCIKL partners and ELIXIR Biodiversity and Plant Communities came together to discuss the Future of Biodiversity and Genomics data integration at the EMBL Wellcome Genome Campus. You can find the agenda on BiCIKL's website.
After 36 months of action, the BiCIKL project will officially end in April 2024, but does it mean that all will be done and dusted come May 2024? Certainly not, point out the partners.
To ensure that the Biodiversity Knowledge Hub will not only continue to exist but will not cease to grow in both use and participation, the one-stop portal will remain under the maintenance of LifeWatch ERIC.
In conclusion, we could say that an appropriate payoff for the project is “Stick together!” as put by BiCIKL’s Joint Research Activity Leader Dr. Quentin Groom.
