1. The last 3 years have seen a global outbreak of media headlines predicting a global insect apocalypse and a subsequent collapse of natural ecosystems, a socalled `ecological armageddon' resulting in the demise of human civilisation as we know it. Despite the worrying implications of these papers, all studies on global insect extinction to date clearly reflect the Prestonian shortfall, the general lack of knowledge on the abundance of species and their trends in space and time. 2. Data currently available concerning global insect abundance trends invariably suffer from phylogenetic, functional, habitat, spatial and temporal bias. Here, we suggest that to follow the real global changes in insect (and all other taxa) communities, biases or shortcomings in data collection must be avoided. 3. An optimised scheme would maximise phylogenetic, functional, habitat, spatial and temporal coverage with minimum investment. Standardised sampling would provide primary data, on a first step in the form of abundance and biomass. Individuals would then be identified to species level whenever possible, with a morphospecies approach or genetics serving as intermediate steps, complementing or even final steps for non-described species. 4. If standardised abundance and ecological data can be readily made available, biodiversity trends can be tracked in real time and allow us to predict and prevent an impending global insect apocalypse.

Antonio O. Soares, Danny Haelewaters, Olga M. C. C. Ameixa, Isabel Borges, Peter M. J. Brown, Pedro Cardoso, Michiel D. de Groot, Edward W. Evans, Audrey A. Grez, Axel Hochkirch, Milada Holecova, Alois Honek, Jan Kulfan, Ana Lillebo, Zdenka Martinkova, J. P. Michaud, Oldrich Nedved, Omkar, Helen E. Roy, Swati Saxena, Apoorva Shandilya, Arnaud Sentis, Jiri Skuhrovec, Sandra Viglasova, Peter Zach, Tania Zaviezo, John E. Losey

Summary: Ladybird populations are compromised by anthropogenic threats, and there is a lack of knowledge on the conservation status and factors driving their population dynamics. Short-term actions such as citizen science programs and education are suggested for conservation and recovery, while long-term actions involve the development of a global monitoring program to fill data gaps.

Summary: Climate warming is a serious anthropogenic stress on the environment, exacerbating the harmful effects of other threats and potentially threatening species preservation and ecosystem services provided by biodiversity. Insects, as central components of many ecosystems, are highly affected by climate change, with effects on physiology, behavior, distribution, and interactions, as well as extreme events.

Triantis, Francois Guilhaumon, David M. Watson, Lluis Brotons, Corrado Battisti, Osanna Chu, Francois Rigal

Summary: Research on island species-area relationships (ISAR) has expanded to incorporate functional (IFDAR) and phylogenetic (IPDAR) diversity. However, we lack comprehensive global analyses of how these categories of island diversity-area relationship (IDAR) vary. In this study, we provide the first comparative evaluation of IDARs at the global scale using avian data sets from 51 archipelagos. Our results show that increasing richness with area drives the non-richness corrected IPDAR and IFDAR. We also find that archipelagos with steeper ISARs have larger differences in slope between IDARs, indicating increased redundancy on larger islands in these archipelagos.

Shrub and precipitation interactions shape functional diversity of nematode communities on the Qinghai-Tibet Plateau

Anning Zhang, Shuyan Chen, Jingwei Chen, Hanwen Cui, Xiaoxuan Jiang, Sa Xiao, Jiajia Wang, Haining Gao, Lizhe An, Pedro Cardoso

Summary: Land use and climate change have significant impacts on biodiversity patterns and ecosystem functioning globally. This study examined the effects of shrub encroachment and precipitation changes on the functional diversity of soil nematode communities on the Qinghai-Tibet Plateau. The results showed that shrubs did not alter functional richness and dispersion, but decreased functional beta diversity, promoting functional homogenization. These effects were influenced by precipitation, with increasing precipitation reversing the negative effects of shrubs on functional richness and dispersion but amplifying their negative effects on functional beta diversity. Structural equation models revealed that shrubs indirectly increased functional richness and dispersion through plant biomass and soil total nitrogen, while directly decreasing functional beta diversity. This study enhances our understanding of the impacts of global climate change on nematode communities in the Qinghai-Tibet Plateau.

Arthropod co-occurrence networks indicate environmental differences between islands and signal introduced species in Azorean native forest remnants

Gabor Pozsgai, Pedro Cardoso, Francois Rigal, Mario Boieiro, Rosalina Gabriel, Eduardo Brito de Azevedo, Paulo A. V. Borges

Summary: Island biotas face imminent threats from anthropogenic impacts. The negative effects of exotic species on taxonomic and functional diversity of local fauna are of major concern. Co-occurrence networks of arthropods in native forest fragments from seven Azorean islands were sensitive to environmental and community dissimilarities, showing clear differences between islands and between indigenous and exotic networks. The presence of exotics in the networks decreased connectance and increased modularity, indicating that they have low associations with other species. Our study highlights the usefulness of co-occurrence network analysis in studying island ecosystems for conservation purposes.

The use of machine learning in species threats and conservation analysis

Vasco Veiga Branco, Luis Correia, Pedro Cardoso

Summary: The concepts and methodologies of machine learning are increasingly used for creating semi-autonomous programmes that can adapt to various problems and decision-making scenarios. This systematic review summarizes the use of machine learning methods in studying species threats and conservation measures, and identifies the emerging trends. Maximum entropy, Bayesian models, ensemble methods, and other algorithms have gained popularity for various conservation problems due to their relevance, ease of implementation, and availability in software packages.

An expert-based global assessment of threats and conservation measures for subterranean ecosystems

Veronica Nanni, Elena Piano, Pedro Cardoso, Marco Isaia, Stefano Mammola

Summary: Subterranean ecosystems are important for biodiversity and human well-being, but there is limited data and global monitoring programs for these ecosystems, hindering effective conservation strategies. We surveyed experts on subterranean ecosystems worldwide to determine the threats and conservation measures. Experts identified habitat change, direct destruction, and climate change as the most relevant threats, and legislation, land protection, and education as the most effective conservation measures. Expert opinion can provide valuable information for conservation interventions when data is lacking.

Time-travelling pathogens and their risk to ecological communities

Giovanni Strona, Corey J. A. Bradshaw, Pedro L. Cardoso, Nicholas Gotelli, Frederic L. Guillaume, Federica Manca, Ville L. Mustonen, Luis Zaman

Summary: By conducting simulated experiments, we found that the thawing of permafrost and the potential 'lab leak' of ancient microorganisms pose risks of biological invasions for modern ecological communities. In most cases, invading pathogens had negligible effects on the invaded community, but in a few cases, they caused substantial losses or gains in species richness.

Using Red List Indices to monitor extinction risk at national scales

Domitilla Raimondo, Bruce E. Young, Thomas M. Brooks, Pedro Cardoso, Dewidine van der Colff, Braulio Ferreira de Souza Dias, Ugo Vercillo, Estevao de Souza, Aino Juslen, Esko Hyvarinen, Lize von Staden, Krystal Tolley, Philip J. K. McGowan

Summary: The Red List Index (RLI) is a key indicator for tracking progress toward biodiversity targets. There are two formulations of RLI used for reporting biodiversity trends at national scales. The national RLI measures national extinction risk, while the disaggregated global RLI measures national contributions to global extinction risk. It is important for governments to monitor a standard set of taxonomic groups using both RLI formulations to ensure effective target tracking and accurate feedback on conservation investments in the post-2020 Global Biodiversity Framework.
