Assessing the extent of ongoing pollinator declines and predicting future changes is key to defining priorities developing adequate policies mitigate consequences such negative trends. Nevertheless, a lack basic information on species identity, trends, traits, requirements hinders our ability make assessments. Such knowledge gaps are particularly pronounced in tropical regions, which expected be severely affected upcoming years by climate change. Identifying taxonomic groups regions have greater can help direct efforts. Recent studies proposed quantify ignorance (shortfalls) methods them for pollinators. Here, we use Brazilian bees as case study evaluate feasibility applying these pollinators provide first assessment gaps. While some adaptations were proposed, evaluated time all seven shortfalls (Linnean, Wallacean, Raunkiaerian, Eltonian, Prestonian, Darwinian, Hutchinsonian) Keartonian impediment. We found that Linnean shortfall at least five-fold one recently European countries with most outstanding (i.e., an increase rate 1% per year, reaching 3% certain families). Also, more than half Brazil’s land area (ca. 57.5% 50x50 km pixels) lacks known bee records, less ten spatially unique indicating Wallacean shortfall. Despite gaps, important sources do exist just not accessible or spread out. Substantial compilation efforts would necessary unite existing into databases.

Abstract Chile's isolation and varied climates have driven the evolution of a unique biodiversity with high degree endemism. As result, Chile encompasses diverse environments, including Mediterranean‐type ecosystem, global hotspot. These environments are currently threatened by anthropogenic land use change impacting integrity local biomes associated species. This area is most intensively sampled in country endemicity native bee Characterizing habitat requirements bees pressing priority to safeguard these insects ecosystem services they provide. We investigated broadscale patterns (Hymenoptera: Apoidea: Anthophila) diversity using newly accessible expert‐validated datasets comprising digitized specimen records from Chilean US collections, novel expert‐validated‐type data for Chile. used generalized dissimilarity modeling (GDM) approach explore both compositional phylogenetic β‐diversity across latitudinal, altitudinal, climate, gradients well‐sampled assemblages Central Using GDM measures increasing environmental dissimilarity, we categorized compared important drivers them classify “wild ecoregions” (WBEs) representing assemblages.

Buzz-world: Global patterns and drivers of buzzing bees and poricidal plants

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2024, Номер unknown

Опубликована: Март 11, 2024

SUMMARY Foraging behavior frequently plays a major role in driving the geographic distribution of animals. Buzzing to extract protein-rich pollen from flowers is key foraging used by bee species across at least 83 genera (these comprise ∼58% all species). Although buzzing widely recognized affect ecology and evolution bees flowering plants (e.g., buzz-pollinated flowers), global patterns drivers biogeography remain unexplored. Here, we investigate within each family how differ with respect species. We found that both distributional richness typically differed for compared hotspots when grouped family. A predictor distribution, but not overall members four five families included analyses (Andrenidae, Halictidae, Colletidae lesser extent, Apidae) was poricidal plant species, which depend on pollination. As highest areas low wind high aridity, discuss biodiversity are likely driven biogeographic factors host availability. Whilst explored State-level data, higher resolution work needed explore local level patterns, perspective, clearly play greater than previously predicted.

We present a checklist of the Swiss bees and provide information on distribution every bee species in all 26 cantons. 632 are reported, including European honeybee Apis mellifera Linnaeus, 1758 exotic Megachile sculpturalis Smith, 1853. Species richness each canton was correlated with area, four largest cantons hosting highest number species. Bee diversity hotspots were located some Alpine inner valleys characterized by dry warm climate due to rain shadow effects surrounding mountains. These mostly steppe-like habitats Valais Graubünden They host diverse wild communities which include unique assemblage submediterranean faunal elements subalpine In addition, these rare strongly disjunct distributions Europe, further stressing conservation priority for conservation. Intensive faunistic surveys performed last 20 years have revealed that about species, either previously unknown Switzerland or had disappeared from country several decades, colonised areas close borders France Italy. Most new reappeared observed warmest area presumably colonized recolonized neighbouring regions following global warming. Lastly, DNA barcodes presented 394 specimens, many so far not represented BOLD database.

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 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 Slovenia, country where central Europe meets Balkan peninsula, barcoded all collected morpho-species. 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 problems, iii) there no gap across bees, iv) genus-specific, but only after curating errors Intense sampling underrepresented regions strict curation repositories needed enhance use

Abstract The mining bee ( Andrena spp.) play a key role in ensuring plant and animal diversity. present study examines their diversity post-agricultural landscape exemplified by the Kampinos National Park (KNP), UNESCO Biosphere Reserve Poland. following hypotheses were addressed: (H1) bees demonstrate narrow ecological amplitude, (H2) there are no indicator species for particular habitats, (H3) studied have same preferences to those presented literature. A total of 40 catch per unit effort samples (CPUE) collected across various habitats with different soil humidity. Forty-six recorded, representing 46% approximately 10% known Polish fauna. Nineteen recorded (41%) assigned CR-NT threat categories, indicating that national park plays significant preserving conservation. None (H1, H2, H3) confirmed. found wide amplitude. Surprisingly, located dry wet soils both characterised high abundance richness. Seventeen indicators distinguished among dominant rarer species. Our findings suggest nigroaenea . ventralis (lower humidity), as well alfkenella minutuloides (higher relationships habitat humidity reported

Climatic stability and species turnover as potential drivers of latitudinal diversity gradients in Chilean wild bees

Insect Conservation and Diversity, Год журнала: 2024, Номер unknown

Опубликована: Дек. 22, 2024

Abstract This study explores the latitudinal diversity gradient (LDG) of wild bees (Hymenoptera: Anthophila) in Chile, a region with diverse climates and geographic isolation. By examining species richness patterns, this research seeks to uncover key factors influencing these patterns Chilean bees. We compiled analysed occurrence records bee from five families, evaluating across gradients. To explain LDG, we tested hypotheses such as Rapoport's effect, mid‐domain effect (MDE), source‐sink dynamics, Climatic Variability Hypothesis. Additionally, conducted cluster analyses beta assessments identify distinct ecoregions understand turnover nestedness along Our analysis revealed mid‐latitudinal peak around 34° S, consistent global bimodal for The data did not support MDE predictions, implying that geometric constraints alone cannot patterns. Instead, positive correlation between extent latitude supports indicating broader environmental tolerances at higher latitudes. Beta showed turnover, nestedness, drives variation gradients, reflecting significant replacement latitudes due changing conditions. Cluster identified groups corresponding Northern, Central, Southern Chile ecoregions, reinforcing substantial shifts composition bands. findings emphasise importance stable supporting high Understanding is vital predicting biodiversity responses climate change guiding conservation strategies, especially Chile's hotspots endemism.
