Abstract This study explores the latitudinal diversity gradient (LDG) of wild bees (Hymenoptera: Anthophila) in Chile, a region with diverse climates and geographic isolation.

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.

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.

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.

Ichneumonidae, or Chilean Darwin wasps, are an important component of South American hymenopteran diversity, but the taxonomic and distributional knowledge on this insect is still deficient. Taking advantage recently updated knowledge, we assessed biogeographic relationships at genus level biodiversity spatial patterns along latitudinal gradient. The results show presence 264 species in Chile, arranged 102 genera 22 subfamilies. Biogeographic based six elements (cosmopolitan (n = 50; 36%), endemic 29; 21%), Neotropical 22; 16%), Holarctic–Oriental 19; 14%), south-temperate 16; 11%) Australasian) composed just three genera: Anacis, Labena, Meringops. Species a bimodal distribution gradient: around 34° 38° S.

Abstract Although mollusks represent Earth’s second most diverse invertebrate group, their natural history and ecology are still scarcely known. The compilation of non-traditional data, such as those from citizen science, represents an alternative to fill these gaps, particularly on striking land snail species Macrocyclis peruvianus. Based long-term we aimed update describe some basic ecological aspects, the distribution protected area types used by M. We performed pairwise comparisons test potential changes in occurrence occupancy among administrative regions, forest types, using chi-squared tests. scientists were also asked provide number peruvianus individuals observed tree that dominated habitat. Thus, tested if snails found could be related a generalized linear mixed model. expanded northern distributional limit, with Nothofagus, evergreen, forests far frequented Parallelly, official areas (65.73%) was significantly higher than privately owned areas.
