Peatland Vascular Plant Leaf N Concentrations (10 Species) From Leaves Collected From N-Addition Plots in an Alberta Peatland, 2011-2015

Development of the oil sands has led to increasing atmospheric N deposition, with values as high as 17 kg N ha-1 yr-1; regional background levels <2 kg N ha-1 yr-1. Bogs, being ombrotrophic, may be especially susceptible to increasing N deposition. To examine responses to N deposition, over five years, we experimentally applied N (as NH4NO3) to a bog near Mariana Lakes, Alberta, at rates of 0, 5, 10, 15, 20, and 25 kg N ha-1 yr-1, plus controls (no water or N addition). In July of each year, we collected new growth of ten species of vascular plants, returned them to the lab, cleaned them, dried and ground them, and ran them on a Flash EA 1112 Series CN Soil Analyzer. Leaf N concentration responses to increasing N input differed between species. Increasing N input led to increasing leaf N concentrations in A. polifolia, C. calyculata, V. vitis-idaea, and V. oxycoccos, with differences in N concentrations between years for all of these species except V. vitis-idaea. There was no leaf N concentration response to increasing N input for E. vaginatum, R. chamaemorus, S. trifolia, or K. polifolia. Water input alone had no significant effect on leaf N concentration for any of the species (p >= 0.18). Although aboveground growth of bog vascular plants may be a general response to increasing N deposition, we do not have a species-specific mechanistic understanding of how growth and leaf/needle N concentrations respond to increasing N deposition, however, there appeared to be no strong evidence for luxury consumption of N.

Peatland Vascular Plant Leaf N Concentrations (5 species) From Leaves collected from N-Addition plots in an Alberta Poor Fen, 2011-2015

Development of the oil sands has led to increasing atmospheric N deposition, with values as high as 17 kg N ha-1 yr-1; regional background levels <2 kg N ha-1 yr-1. To examine responses to N deposition, over five years, we experimentally applied N (as NH4NO3) to a poor fen near Mariana Lake, Alberta, at rates of 0, 5, 10, 15, 20, and 25 kg N ha-1 yr-1, plus controls (no water or N addition). In July of each year, we collected new growth of 5 species of vascular plants, returned them to the lab, cleaned them, dried and ground them, and ran them on a Flash EA 1112 Series CN Soil Analyzer Leaf N concentrations in C. calyculata, A. polifolia, and V. oxycoccos increased significantly with increasing N addition (Fig. 5). For C. calyculata and A. polifolia, there were differences in N concentrations between years, but the regression slopes describing the response to N addition were consistent across all years. Leaf N concentrations were unaffected by N addition for E. vaginatum and S. palustris, with the latter exhibiting interannual differences in leaf N concentrations. Water addition alone had no significant effect on N concentrations for any of the vascular plant species (p >= 0.67).

Plant biomass collection on the Biodiversity Experiment at the Kellogg Biological Station, Hickory Corners, MI (2001 to 2011)

Dataset Abstract The biodiversity gradient experiment is an additional long-term study located within the LTER Main Site complex, in which a series of 21 different experimental treatments vary in plant species diversity. Treatments range from bare soil to single-crop rotations to multiple-crop rotations to annually fallowed fields with early successional plant communities. Plant species richness thus varies from 0 to >15 in any given 3-year rotation cycle. Treatment plots are 9.1×27.4 meters (30×90 feet) replicated in each of 4 randomized blocks. The study site was established in 2000. original data source http://lter.kbs.msu.edu/datasets/112

Data from: Introduced bees (Osmia cornifrons) collect pollen from both coevolved and novel host-plant species within their family-level phylogenetic preferences

Studying the pollen preferences of introduced bees allows us to investigate how species utilize host-plants when establishing in new environments. Osmia cornifrons is a solitary bee introduced into North America from East-Asia for pollination of crops in the Rosaceae. We investigated whether O. cornifrons 1) more frequently collected pollen from host-plant species they coevolved with from their geographic origin, or 2) prefer hosts-plant species of specific plant taxa independent of origin. To address this question, using pollen metabarcoding we examined the identity and relative abundance of pollen in larval provisions from nests located in different habitats with varying abundance of East-Asian and non-Asian plant species. Our results show that O. cornifrons disproportionately, yet not exclusively, collected pollen from their native range. Plants in the family Rosaceae were their most preferred pollen hosts, where they differentially collected species native to East-Asia, Europe, or North America depending on the landscape. Our results suggest that while O. cornifrons more frequently collect pollen of East-Asian origin, the collection of pollen from novel species within their phylogenetic familial affinities can facilitate pollinator establishment. This phylogenetic preference highlights the effectiveness of O. cornifrons as crop pollinators of a variety of Rosaceae crops from different geographic origins. Ourresults imply that globalization of non-native plant species may ease the naturalization of their coevolved pollinators outside of their native range.

Ecological data from: Combining botanical collections and ecological data to better describe plant community diversity

In this age of rapid biodiversity loss, we must continue to refine our approaches to describing variation in life on Earth. Combining knowledge and research tools from multiple disciplines is one way to better describe complex natural systems. Understanding plant community diversity requires documenting both pattern and process. We must first know which species exist, and where (i.e., taxonomic and biogeographic patterns), before we can determine why they exist there (i.e., ecological and evolutionary processes). Floristic botanists often use collections-based approaches to elucidate biodiversity patterns, while plant ecologists use hypothesis-driven statistical approaches to describe underlying processes. Because of these different disciplinary histories and research goals, floristic botanists and plant ecologists often remain siloed in their work. Here, using a case study from an urban greenway in Colorado, USA, we illustrate that the collections-based, opportunistic sampling of floristic botanists is highly complementary to the transect- or plot-based sampling of plant ecologists. We found that floristic sampling captured a community species pool four times larger than that captured using ecological transects, with rarefaction and non-parametric species estimation indicating that it would be prohibitive to capture the "true" community species pool if constrained to sampling within transects. We further illustrate that the discrepancy in species pool size between approaches led to a different interpretation of the greenway's ecological condition in some cases (e.g., transects missed uncommon cultivated species escaping from nearby gardens) but not others (e.g., plant species distributions among functional groups were similar between species pools). Finally, we show that while using transects to estimate plant relative abundances necessarily trades off with a fuller assessment of the species pool, it is an indispensable indicator of ecosystem health, as evidenced by three non-native grasses contributing to 50% of plant cover along the highly modified urban greenway. We suggest that actively fostering collaborations between floristic botanists and ecologists can create new insights into the maintenance of species diversity at the community scale.

Plant collections for conservation and restoration: can they be adapted and adaptable?

Plant collections are important for the conservation of threatened species, and as a source of material for ecological restoration. Typically we want collections to have high genetic diversity so populations founded from it are adaptable to future challenges. Sometimes, we have additional objectives for collections, such as enrichment for desirable traits controlled by adaptive alleles. We used landscape genomic datasets for two plants, Westringia fruticosa and Wilkiea huegeliana, to design collections that are genetically diverse, and that are adapted to warming climates. We characterized temperature adaptation by: (i) using the mean annual temperature of the sites of origin of the plants, and (ii) using the representation of alleles that are associated with warm temperatures. In Westringia fruticosa, there was a negative correlation, or tradeoff between designing a collection that was both genetically diverse and adapted to warm temperatures. This tradeoff was weaker in Wilkiea huegeliana. We hypothesized this was because neutral genetic variation was strongly correlated with temperature in Westringia fruticosa, and not in Wilkiea huegeliana. Accordingly, when we shuffled the temperature data, breaking up the covariance between Westringia fruticosa genetic variation and temperature, there was a relaxation of the observed tradeoff. In sum, we explore tradeoffs between genetic diversity and environmental adaptation in plant collections, and highlight factors that influence the strength of these tradeoffs. This represents a useful step towards understanding when selection will have a large cost in genetic diversity, and when it will be possible to design a collection that is both adapted and adaptable.

Results of questionnaire on live plant health nematode collections

In the framework of the Euphresco project 2016-F-186 'Inventory of living collections of cyst and root knot nematodes in Europe and their maintenance techniques (Cyst and Melo Collect)', a survey was organised during the Autumn 2017 with the aim to collect information on the live nematode collections in different countries. 32 (reference) collections in Austria, Belgium, Canada, Czech Republic, France, Germany, Italy, Latvia, Mexico, Netherlands, Portugal, Spain, United Kingdom, and United States of America participated in the survey. Of the 32 mentioned collections the preferred nematode populations are clearly different between the USA and Europe: the tropical Meloidogyne species are the most represented in North America while Globodera species are in Europe. The comparison of the protocols for live nematode storage for short and long periods of time showed high variability, although in general, Globodera spp. can be stored at 4 °C for longer time (>20 years) than Meloidogyne spp., whose optimal storage time is 8 months at 14 °C, when kept in soil. The need to verify the population for its trueness, with other words, the frequency of identification differs; various possibilities are mentioned between never and almost monthly to frequently, each time the nematodes are extracted from the soil (90 days for PCN, 16 weeks for Meloidogyne) to yearly or only upon arrival. The frequency depends on the amount of time people can afford to put into this work and the risk assessment for getting cross contamination. The conditions for rearing and maintaining were inventoried as well. For Meloidogyne spp., host differences for rearing and maintaining them are rarely observed (often Solanum lycopersicum -tomato- is used for both), although Ficus carina for long maintenance of Meloidogyne spp. and Solanum dulcamara for M. fallax have been used in France (pers. comm. Fabrice Ollivier, ANSES). For cyst nematode species their specific host is used for both rearing and maintenance purposes: Solanum tuberosum (potato), Nicotiana tabacum (tobacco), or Glycine max (soybean) are used respectively for the potato cyst nematodes (Globodera rostochiensis and G. pallida), G. tabacum and G. glycines.
