Understanding and reversing biodiversity decline in the Anthropocene requires robust data on species taxonomic identity, distribution, ecology, population trends. Data deficits hinder assessments conservation, despite major advances over past few decades, our understanding of bee diversity, distribution Europe is still hampered by such shortfalls. Using a unique digital dataset wild occurrence we identify seven critical shortfalls which are an absence knowledge geographic distributions, (functional) trait variation, dynamics, evolutionary relationships, biotic interactions, tolerance to abiotic conditions. We describe "BeeFall," interactive online Shiny app tool, visualizes these highlights missing data. also define new impediment, Keartonian Impediment, addresses high-quality situ photos illustrations with diagnostic characteristics directly affects outlined Shortfalls highly correlated at both provincial national scales, identifying key areas where gaps can be filled. This work provides important first step towards long-term goal mobilize aggregate European into multi-scale, easy access, shareable, updatable database inform research, practice, policy actions for conservation bees.

ABSTRACT Motivation Pollinators play a crucial role in maintaining Earth's terrestrial biodiversity. However, rapid human‐induced environmental changes are compromising the long‐term persistence of plant‐pollinator interactions. Unfortunately, we lack robust, generalisable data capturing how communities structured across space and time. Here, present EuPPollNet (European Plant‐Pollinator Networks) database, fully open European‐level database containing harmonised taxonomic on interactions referenced both time, along with other ecological variables interest. In addition, evaluate sampling coverage EuPPollNet, summarise key structural properties networks. We believe will stimulate research to address gaps guide future efforts conservation planning.

DNA barcoding insufficiently identifies European wild bees (Hymenoptera, Anthophila) due to undefined species diversity, genus‐specific barcoding gaps and database errors

Molecular Ecology Resources, Год журнала: 2024, Номер 24(5)

Опубликована: Март 25, 2024

Abstract Recent declines in insect abundances, especially populations of wild pollinators, pose a threat to many natural and agricultural ecosystems. Traditional species monitoring relies on morphological character identification is inadequate for efficient standardized surveys. DNA barcoding has become standard approach molecular organisms, aiming overcome the shortcomings traditional biodiversity monitoring. However, its efficacy depends completeness reference databases. Large efforts are (almost entirely) lacking European countries such patchy data limit Europe‐wide analyses precisely how apply bee identification. Here, we advance towards an effective bees. We conducted high‐effort survey bees at junction central southern Europe barcoded all collected morphospecies. For global analyses, complemented our barcode dataset with relevant delimitation, general genus‐specific gaps examined error rate repositories. found that (i) sixth specimens from Slovenia could not be reliably identified, (ii) delimitation methods show numerous systematic discrepancies, (iii) there no gap across (iv) genus specific, but only after curating errors Intense sampling underrepresented regions strict curation repositories needed enhance use

Big data, big problems? How to circumvent problems in biodiversity mapping and ensure meaningful results

Ecography, Год журнала: 2024, Номер 2024(8)

Опубликована: Май 30, 2024

Our knowledge of biodiversity hinges on sufficient data, reliable methods, and realistic models. Without an accurate assessment species distributions, we cannot effectively target stem loss. Species range maps are the foundation such efforts, but countless studies have failed to account for most basic assumptions mapping practices, undermining credibility their results potentially misleading hindering conservation management efforts. Here, use examples from recent literature broader community highlight substantial shortfalls in current practices consequences both analyses management. We detail how different decisions data filtering impact outcomes analysis provide practical recommendations steps more analysis, whilst understanding limits what available will reliably allow methods appropriate. Whilst perfect not possible many taxa given limited biases, ensuring within reasonable inherent is crucial ensure appropriate use. By embracing enacting best can accuracy improved comparability going forward, ultimately enhancing our ability facilitate protection natural world.

The Distribution of Wild Bee Species Along a Latitudinal Gradient in Northern Europe Depends on Their Flower Preferences

Diversity and Distributions, Год журнала: 2025, Номер 31(2)

Опубликована: Фев. 1, 2025

ABSTRACT Aim The functional diversity of bees contribute to the maintenance plant biodiversity because different species wild prefer and pollinate plants. Many bees, in particular with narrow flower preferences or specialised habitat requirements, are threatened by landscape homogenisation climate change. Nonetheless, we still lack an understanding large‐scale impacts anthropogenic stressors on distribution bee preferences. Location Northern Europe: Norway, Denmark Germany. Methods We combine a dataset comprising ~30,000 observations presences absences occurrences from structured surveys at 269 sites northern Europe investigate if modulate distributions across multiple environmental gradients. Bees were assigned continuous trait separating preference for short vs. tubular flowers. Results observe that either flowers (Fabaceae) plants shallow (including Apiaceae Brassicaceae) can be described score. likelihood observing along latitudinal gradient—encompassing variation temperature, atmospheric N deposition elevation—is dependent its Specifically, have higher occurrence latitudes, while non‐tubular increase towards south. Main Conclusions Our results improve our how species‐specific drives community‐wide shifts therefore help devise region‐specific conservation strategies.

Abstract While global patterns of bee diversity have been modelled, our understanding fine‐scale regional is more limited, particularly for under‐sampled regions such as Africa. South Africa among the exceptions on African continent; its fauna (ca. 1253 species) has well collected and documented, including mass digitising natural history collections. It a region with high floral diversity, habitat heterogeneity variable rainfall seasonality. Here, we combine species distributional database (877 geospatial modelling approach to determine (~11 × 11 km grid cell resolution) hotspots richness, endemism range‐restricted species. Our analyses, based probabilities occurrence surfaces each across 108,803 two‐minute cells, reveal three richness: Winter rainfall, Aseasonal Early‐to‐late summer rainfall. These contain large numbers endemic geographically restricted taxa. Hotspots include Fynbos, Succulent Karoo Desert biomes; latter showing 6–20 times per unit area than other biomes. results conform species‐area patterns: areas higher‐than‐expected density are largely concentrated in Mediterranean arid habitats. This study further enhances knowledge identifying richness keystone group insects enabling these be accounted when setting conservation priorities.

Diversity can be examined and interpreted from various perspectives, including species richness, genetic phenotypic differences, variation in behaviors natural history, phylogenetic history. Centuries of taxonomic research have revealed approximately 21,000 bee worldwide. These subdivided into a hierarchy subgroups that reflects their evolutionary thanks to the increasingly more comprehensive hypotheses available. Advances systematics enhanced our understanding how diversity has evolved, origin Cretaceous, shifts geographical distribution, evolution social parasitic behaviors, changes relationships between bees plants they visit throughout 120-million-year shared An important outcome enduring relationship with flowering is vital role play pollination both agricultural ecosystems. Habitat loss, climate change, other anthropogenic environmental alterations led declines populations, which sparked concerns about conservation highlighted importance complementary aspects diversity, components this variation.
