Abstract An animal’s diet breadth is a central aspect of its life history, yet the factors determining why some species have narrow dietary breadths (specialists) and others broad (generalists) remain poorly understood. This challenge pronounced in herbivorous insects due to incomplete host plant data across many taxa regions. Here, we develop validate machine learning models predict pollen bees, using bee phylogeny occurrence for 682 native United States, aiming better understand key drivers. We found that specialist bees made an average 72.9% their visits plants could be predicted with high accuracy (mean 94%). Our generalist species, which up minority our dataset, lower 70%). The tested on spatially phylogenetically blocked revealed most informative predictors are phylogenetic diversity, species’ geographic range, regional abundance. findings also confirm range size predictive both male female mostly visit plants. Overall, results suggest can use visitation regions taxonomic groups where unknown, though predicting generalists may more challenging. These methods thus enhance understanding plant-pollinator interactions, leading improved conservation outcomes pollination services provide.

Species assemblages constrained by ecological and evolutionary processes (and the interactions between them) are vulnerable to changes in their environment. Network analyses do not explicitly build phylogenetic histories when exploring how they assembled, yet can be a critical source of information for understanding species may incorporated into webs. Recent studies have revealed unexpected diversity monophyletic clade native Fijian bees subgenus Lasioglossum (Homalictus). These undergone remarkable recent radiation with evidence conservatism elevational niches physiological traits. Here we use bipartite network analyses, as an adjunct further inform likely ancestral elevations these explore patterns occupied other niches.

Native bees augment pollination services in the Northern Hemisphere, especially cultivated apple crops, yet Southern Hemisphere contexts are poorly known. We observed foraging behaviour of 69 354 invertebrate flower visitors Australian orchards (two regions, 3 years) to assess efficacy service ( P eff ). stingless and introduced honey were most abundant efficacious pollinators Tetragonula = 6.16; Apis 13.02), with becoming important providers above 22°C. However, visits by tree-nesting decreased distance from native forest (less than 200 m) their tropical/subtropical distribution precludes other major apple-producing regions. More broadly distributed allodapine halictine transferred pollen per-visit, but low abundances reduce efficacies Exoneura 0.03; Lasioglossum 0.06), resulting a general dependence on bees. This reliance is burden biogeography, since key Andrena, , Bombus Osmia ) do not naturally occur Australasia—where there only 15% generic overlap Central Asian sympatric wild distributions (cf. Palaearctic 66% Nearctic 46% overlaps). The historical biogeography therefore drives an extreme one species for Australia.

Abstract Habitat loss is causing declines in native bees and reducing pollination services. Revegetation can be used to reverse these declines, this restoration technique attracts growing efforts resources. However, how the quality of revegetation affects bee abundance, diversity their services not well understood, limits opportunities improve outcomes. To assess gap, we surveyed floral revegetated landscapes ranging habitat quality, compared among each other remnant cleared areas. We also measured using two phytometer species, which pollinated by only, or both introduced honey ( Apis mellifera ). found that richness were higher within treatments diversity. In addition, while provided uniform across treatments, vegetation supported greater plant species only. These results indicate characterized establishment a more diverse set has potential restore associated for investigated, had occurred might require time. suggest preserving should highest priority conservation action, practitioners landowners wishing support landscape‐level services, aim high flowering
