Native Bee and Nectar-Producing Plant Community Data from Iowa and Missouri (2017-2018)
The majority of tallgrass prairie in the American Midwest has been lost, largely due to extensive conversion to agriculture, with negative impacts on prairie-dependent taxa. Pastureland managed with both periodic fire and grazing (“pyric herbivory”) to mirror historic disturbance shows promise as a tool to restore grassland species’ diversity. The benefits of pyric herbivory management to the abundance and diversity of grassland insect pollinators has been demonstrated at "site" level but finer spatial scale benefits remain unclear. These data focus on native bee communities and nectar-producing flower abundance within sites either managed with graze and burn (same fire schedule as burn only but with cattle grazing) or patch-burn graze (grazing by cattle with a burn on one third of the site every year). The graze and burn sites were further managed against an invasive grass (tall fescue; Schedonorus arundinaceus) where one third of the site was left as a control, two thirds were sprayed with the herbicide glyphosate in 2014 and one of those two thirds was also seeded with native prairie plants the following spring. Native bees and flowers were sampled from May to August 2017 and 2018 on six sites in southern Iowa (Ringgold Co.) and norther Missouri (Harrison Co.).
Molecular sequencing and morphological identification reveal similar patterns in native bee communities across private and public grasslands of eastern North Dakota
<p>Bees play a key role in the functioning of human-modified and natural ecosystems by pollinating agricultural crops and wild plant communities. Global pollinator conservation efforts need large-scale and long-term monitoring to detect changes in species' demographic patterns and shifts in bee community structure. The objective of this project was to test a molecular sequencing pipeline that would utilize a commonly used locus, produce accurate and precise identifications consistent with morphological identifications, and generate data that are both qualitative and quantitative. We applied this amplicon sequencing pipeline to native bee communities sampled across Conservation Reserve Program (CRP) lands and native grasslands in eastern North Dakota. We found the 28S LSU locus to be more capable of discriminating between species than the 18S SSU rRNA locus, and in some cases even resolved instances of cryptic species or morphologically ambiguous species complexes. Overall, we found the amplicon sequencing method to be a qualitatively accurate representation of the sampled bee community richness and species identity, especially when a well-curated database of known 28S LSU sequences is available. Both morphological identification and molecular sequencing revealed similar patterns in native bee community structure across CRP lands and native prairie. Additionally, a genetic algorithm approach to compute taxon-specific correction factors using a small subset of the most concordant samples demonstrated that a high level of quantitative accuracy could be possible if the specimens are fresh and processed soon after collection. Here we provide a first step to a molecular pipeline for identifying insect pollinator communities. This tool should prove useful for future national monitoring efforts as use of molecular tools becomes more affordable and as numbers of 28S LSU sequences for pollinator species increase in publicly-available databases.</p>
Characterization of Salix nigra floral insect community and activity of three native Andrena bees
<i>Salix nigra</i> (black willow) is a widespread tree that hosts many species of polylectic hymenopterans and oligolectic bees of the genus <i>Andrena</i>. The early flowering of <i>S. nigra</i> makes it an important nutritive resource for insects emerging from hibernation. However, since <i>S. nigra</i> is dioecious, not all insect visits will lead to successful pollination. Using both visual observation and pan-trapping we characterized the community of insects that visited <i>S. nigra</i> flowers and assessed differences among male and female trees as well as the chemical and visual drivers that influenced community composition across three years. We found that male trees consistently supported higher diversity of insects than female trees and only three insect species, all <i>Andrena spp.</i>, consistently visited both sexes. Additionally, <i>A. nigrae</i>, which was the only insect that occurred more on female than male flowers, correlated strongly to volatile cues. This suggests that cross-pollinators cue into specific aspects of floral scent, but diversity of floral visitors is driven strongly by visual cues of yellow male pollen. Through time the floral activity of two <i>Andrena</i> species remained stable, but <i>A. nigrae</i> visited less in 2017 when flowers bloomed earlier than other years. When native bee emergence does not synchronize with bloom, activity appears to be diminished which could threaten species that subsist on a single host. Despite the community diversity of <i>S. nigra</i> flowers, its productivity depends on a small fraction of species that are not threatened by competition, but rather by rapidly changing conditions that lead to host-insect asynchrony.

Spillover of chalkbrood fungi to native solitary bee species from non-native congeners
<p>Introduced, managed bees such as mason bees (genus <em>Osmia</em>) can confer significant pollination benefits to agricultural systems, but a risk of introducing non-native species into new ecosystems is the co-introduction of pathogens along with them. Pathogen spillover to wild, native bees may then drive native bee species declines.</p> <p>This study examined prevalence of the chalkbrood-causing fungal genus <em>Ascosphaera</em> in the nests of both non-native and native mason bee species. We conducted large-scale trap-nesting and pan-trapping efforts across the Mid-Atlantic United States with community scientists. Using molecular methods, nests were screened for all known <em>Ascosphaera</em> species in which genetic sequences have been published. After finding <em>Ascosphaera</em> species first described in Asia, we compared their local prevalence with the local abundance of mason bees from Asia. Lastly, we compared the prevalence of co-introduced Ascosphaera species across sites with a variety of landcover profiles.</p> <p>Results indicate species originally described in Japan, <em>Ascosphaera naganensis</em> and <em>Ascosphaera fusiformis</em>, are now present in native Virginia mason bees, <em>Osmia lignaria</em> and <em>Osmia georgica</em>, with high prevalence of <em>A. naganensis</em> found in <em>O. georgica</em>.</p> <p>We also found that the declining native mason bee <em>O. georgica</em> experienced higher prevalence of non-native <em>Ascosphaera</em> spp. at sites with larger numbers of non-native <em>O. cornifrons</em> and <em>O. taurus</em>, perhaps indicating greater likelihood of spillover of these <em>Ascosphaera</em> species with greater sources of transmission. Lastly, when the proportion of agricultural landcover surrounding bee nests was high, there was significantly greater prevalence of non-native <em>Ascosphaera</em> in <em>O. georgica</em> compared to more natural landcover types.</p> <p>Synthesis and applications. Through community science programming, we documented species of Japanese chalkbrood fungi inside native mason bee nests in North America. Native mason bees encounter non-native fungi more frequently with increasing abundance of non-native mason bees. Agricultural landscapes may exacerbate spillover of non-native fungi for native mason bees. The use of non-native bee species in agriculture should involve monitoring native bees for pathogens in the surrounding area for detection of spillover and species declines.</p>
