Wildflower survey data from French Broad River Basin, North Carolina, 2014
This dataset includes measures of the abundance of blooming wildflowers from field surveys conducted in the French Broad River Basin in western North Carolina, USA. This basin is in the Southern Appalachian Mountains. Data were collected to examine the spatial and seasonal supply of biodiversity-based cultural ecosystem services (CES), in this case, nature study by viewing wildflowers. The data includes blooming species observed at 69 sites on public and private lands during the period 2014-04-01 to 2014-08-08. Flower species were characterized as charismatic if represented in tourism websites. Environmental data for 56 sites are provided: elevation, early season precipitation, mean summer temperature, land cover diversity, tree cover, vegetation structural diversity, vegetation annual productivity, and building density at local and landscape scales. Graves et al. (2017, doi: 10.1007/s10980-016-0452-0) used these data to analyze seasonal shifts in supply of floral resources and how those shifts impacted public access to projected resource hotspots. Relationships between landscape gradients, biodiversity, and ecosystem service supply varied seasonally, and the analysis identified CES hotspots otherwise obscured by simple proxies. Landscape models of biodiversity-based cultural ecosystem services should include seasonal dynamics of biotic communities to avoid under- or over-emphasizing the importance of specific locations in ecosystem service assessments.

Data from: Homogenization of populations in the wildflower Texas bluebonnet (Lupinus texensis)
Wildflowers seeds are routinely spread along highways and thoroughfares throughout North America as part of federal beautification policy, but the genetic effect of the introduction of these cultivated populations on wild populations of the same species is unknown. Interbreeding may occur between these seeded and wild populations, resulting in several possible outcomes. Here we sample 187 individuals in 12 matched pairs of neighboring wild and seeded populations of the Texas bluebonnet (Lupinus texensis), a species popular in commercially available wildflower seed mixes used by both the Texas Department of Transportation and the public. We use genotyping by sequencing to identify 11,741 genome-wide single nucleotide polymorphisms, as well as a smaller number of SNPs from the chloroplast genome, to analyze population structure and genetic diversity within and between the populations. We find a striking lack of population structure both between wild and seeded populations and amongst wild populations. STRUCTURE analyses indicate that all populations are apparently panmictic. This pattern may be explained by extensive swamping of wild populations by seeded germplasm and increased dispersal of semi-domesticated seed across this species' core native range by humans. We discuss the possible negative and positive ramifications of homogenization on the evolutionary future of this popular wildflower species.
Rare and declining bee species are key to consistent pollination of wildflowers and crops across large spatial scales
<p>Biodiversity promotes ecosystem function in experiments, but it remains uncertain how biodiversity loss affects function in larger-scale natural ecosystems, where rare and declining species which are likely to be lost and function needs to be maintained across space and time. Here we explore the importance of rare and declining bee species to the pollination of three wildflowers and three crops using large-scale (72 sites across 5,000 km2), multi-year datasets. Half (82/164) bee species were rare or declining, but these species provided ~15% of overall pollination. To determine the number of species important to ecosystem function, we used two methods of 'scaling up', both of which have previously been used for biodiversity-function analysis. First, we summed bee species' contributions to pollination across space and time and then found the minimum set of species needed to provide a threshold level of function across all sites; according to this method, effectively no rare and declining bee species were important to pollination. Second, we account for the "insurance value" of biodiversity by finding the minimum set of bee species needed to simultaneously provide a threshold level of function at each site in each year. The second method leads to the conclusion that 25 rare and eight declining bee species (36% and 53% of all rare and declining bee species, respectively) are important. Our findings provide some of the strongest evidence yet for the importance of rare and declining species, thereby providing a more direct link between real-world biodiversity loss and ecosystem function.</p>

Experimental addition of marine-derived nutrients affects wildflower traits in a coastal meta-ecosystem
<p>Organismal movement can bring individuals, resources, and novel interactions across ecosystem boundaries and into recipient habitats, thereby forming meta-ecosystems. For example, Pacific salmon ecosystems receive large marine-derived nitrogen subsidies during annual spawning events, which can have a wide range of effects on aquatic and terrestrial plant species and communities. In this study, we evaluate the effects of cross-ecosystem nutrient subsidies on terrestrial plant growth and reproduction. We conducted a large-scale field experiment with four treatments: (1) addition of a pink salmon (<em>Oncorhynchus</em> <em>gorbuscha</em>) carcass, (2) addition of the drift seaweed rockweed (<em>Fucus</em> <em>distichus</em>), (3) addition of both salmon + rockweed, and (4) a control. We examined treatment effects on leaf nitrogen and fitness-associated floral traits in four common estuarine wildflower species. We found elevated leaf ∂<sup>15</sup>N in all plant species and all sampling years in treatments with salmon carcass additions but did not observe any differences in leaf percent nitrogen. We also observed larger leaf area in two species, a context-dependent increase in floral display area in two species, and a limited increase in plant seed set in response to both salmon carcass treatments. In sum, our study suggests that marine nutrients can affect terrestrial plant growth and reproduction.</p>

Data from: Phenological mismatch with trees reduces wildflower carbon budgets
Interacting species can respond differently to climate change, causing unexpected consequences. Many understory wildflowers in deciduous forests leaf out and flower in the spring when light availability is highest before overstory canopy closure. Therefore, different phenological responses by understory and overstory species to increased spring temperature could have significant ecological implications. Pairing contemporary data with historical observations initiated by Henry David Thoreau (1850s), we found that overstory tree leaf out is more responsive to increased spring temperature than understory wildflower phenology, resulting in shorter periods of high light in the understory before wildflowers are shaded by tree canopies. Because of this overstory-understory mismatch, we estimate that wildflower spring carbon budgets in the northeastern United States were 12-26% larger during Thoreau's era and project a 10-48% reduction during this century. This underappreciated phenomenon may have already reduced wildflower fitness and could lead to future population declines in these ecologically important species.
Data from: Ecological factors influence balancing selection on leaf chemical profiles of a wildflower
<div> <div> <div> <div> <p>Balancing selection is frequently invoked as a mechanism to maintain variation within and across populations. However, rigorous tests demonstrating balancing selection operating in nature are scarce, particularly on complex traits, which frequently display high levels of variation. Leveraging a focal polymorphism, leaf chemical profile in a perennial wildflower (<em>Boechera stricta</em>, Brassicaceae), we investigated the ecological and genetic mechanisms that may influence the maintenance of variation in this trait. A suite of common garden and greenhouse experiments showed that the alleles underlying variation in chemical profile have contrasting fitness effects across environments, implicating two ecological drivers of selection on chemical profile: herbivory and drought. Phenotype-environment associations and molecular genetic analyses revealed additional evidence of past selection by these drivers. Together, these data are consistent with balancing selection on chemical profile, likely caused by pleiotropic effects of genes that influence secondary chemical biosynthesis on herbivore defense and drought response.</p> </div> </div> </div> </div>
The attraction of western honey bees (Apis mellifera L.) to commercially available pollen substitutes and wildflower pollen
<p>Many beekeepers supplement their western honey bee (<em>Apis mellifera</em>) colonies with artificial pollen substitutes to provide colonies with adequate nutrition during times of low pollen availability or limited pollen quality. Here, we provided caged adult worker bees with three commercially available pollen substitutes (AP23, MegaBee, UltraBee) and wildflower pollen to determine which diet is most attractive to the bees. We measured diet weight change (as a proxy for consumption) and observed honey bee behavior to test for bee preferences for certain diets. We found that the bees interacted with and consumed more wildflower pollen than they did with any of the commercially available pollen substitutes. Ultimately, our data suggest that bees have a strong preference for wildflower pollen over that of commercially available pollen substitutes.</p>
Effects of temperature and wildflowers on survival and macronutrient stores of the alfalfa leafcutting bee under extended cold storage
<p><em>Megachile rotundata</em> (F.) is an important pollinator of alfalfa in the United States. Enhancing landscapes with wildflowers is a primary strategy for conserving pollinators and may improve sustainability of <em>M. rotundata</em>. Changing cold storage temperatures from a traditionally static thermal regime (STR) to a fluctuating thermal regime (FTR) improves overwintering success and extends <em>M. rotundata</em>'s shelf life and pollination window. Whether floral resources enhance overwintering survival and/or interact with thermal regime are unknown. With these data sets we tested the combined effects of enhancing alfalfa fields with wildflowers and thermal regime on survival and macronutrient stores under extended cold storage (i.e., beyond one season). <em>Megachile rotundata </em>adults were released in alfalfa plots with and without wildflower strips summer 2017. Completed nests were harvested in September 2017 and stored in STR. After a year, cells were randomly assigned to remain in STR for 6 months or in FTR for a year of extended cold storage; emergence rates were observed monthly. Macronutrient levels (i.e., sugars, glycogen, trehalose and total lipids) of newly emerged females were assessed. </p>
Data from: Developing perennial wildflower strips for use in Mediterranean orchard systems
<p>To support sustainable food production and the delivery of ecosystem services through ecological intensification, wildflower strips have become a popular strategy. Despite their success in temperate orchard systems, they remain understudied in Mediterranean ecosystems, which poses a significant barrier to uptake. In order to further promote their adoption, seed mixes must be optimised for commercial orchard systems and for the Mediterranean climate. Plant species should be selected for their consistent performance, while the availability of resources for ecosystem service providers determines the quality of the wildflower strip. In this study, the suitability of 12 native perennial forbs and two tussock-forming grass species for wildflower strips in commercial <em>Citrus</em> orchards was assessed over a three year period. Distinct resources for natural enemies according to the different plant growth stages was used an indicator of wildflower strip quality. The wildflower strips were managed under two different cutting strategies; i) standard management, in which wildflower strips were cut once annually in February, ii) active management, in which wildflower strips were cut two additional times each year. The establishment and success of the sown species were compared. The influence of wildflower strips and their management on plant species richness, community structure, and the provision of resources was compared with iii) a control treatment, in which alleyways were managed conventionally by cutting any naturally occurring vegetation to a height of ≤5 cm, four to five times annual. For the first time, the performance of native perennial plant species has been assessed in Mediterranean orchard systems and a seed mix developed targeting pest regulation services. The wildflower strips were successful in increasing plant species richness and the available resources expected to support natural enemies. However, only wildflower strips managed with cutting once annually enhanced vegetation cover relative to the control, whilst extending the flowering period. This study therefore provides crucial tools for the further development of sustainable approaches to food production in Mediterranean orchard systems. </p>
Data from: The interplay of intercropping, wildflower strips and weeds in conservation biological control and productivity
<p>Diversifying agroecosystems is instrumental to reduce pesticide use in agriculture. While different diversification practices have the potential to reduce pests, their integration at the agroecosystem level and the evaluation of their multifunctional effects remain limited. Through a two-year field experiment conducted in Germany, we tested whether associating intercropping (faba bean-wheat, followed by breadseed poppy-barley) with pluriannual wildflower strips strengthens the biological regulation of aphid pests and weeds, and enhances cropping system productivity. The contribution of flowering weeds to conservation biological control was also analysed. Aphid colonization rates, but also predator colonization and predation rates, on bean and poppy were consistently lower in intercropping compared to sole cropping. Associating wildflower strips to intercropping enhanced aphid predation in bean-wheat intercropping, and further reduced aphid colonization at 10 m distance from the flower strip but not at 20 m in poppy-barley intercropping. Weed biomass was strongly reduced in intercropping compared to sole crop bean and poppy, and did not significantly affect bean and poppy yields in intercropping. The cover of one flowering weed species, <em>Matricaria recutita</em>, was negatively correlated to aphid colonization rate and positively correlated to predation rate in bean-wheat intercropping. In poppy-barley intercropping, <em>M. recutita</em> flowers were visited more often by predatory hoverflies in plots adjacent to wildflower strips. Finally, land equivalent ratio, measuring land-use efficiency, was consistently higher than 1, and the highest in bean-wheat intercropping associated to wildflower strips. The study shows that intercropping is key to control multiple pests and enhance land-use efficiency, and demonstrates that associating wildflower strips to intercropping can strengthen biological control and cropping system productivity. Flowering weeds, maintained at an acceptable level through intercropping, turn out to be relevant functional biodiversity in interacting with wildflower strips to support natural enemies for conservation biological control.</p>
