Data from: Edge effects and mating patterns in a bumblebee-pollinated plant

Dorothy Christopher, Randall J Mitchell, Dorset W Trapnell, Patrick A Smallwood, Wendy R Semski & Jeffrey D Karron
Researchers have long assumed that plant spatial location influences plant reproductive success and pollinator foraging behavior. For example, many flowering plant populations have small, linear, or irregular shapes that increase the proportion of plants on the edge, which may reduce mating opportunities through both male and female function. Additionally, plants that rely on pollinators may be particularly vulnerable to edge effects if those pollinators exhibit restricted foraging and pollen carryover is limited. To explore the...

The Rhododendron genome and chromosomal organization provide insight into shared whole-genome duplications across the heath family (Ericaceae)

Valerie L. Soza, Dale Lindsley, Adam Waalkes, Elizabeth Ramage, Rupali P. Patwardhan, Joshua N. Burton, Andrew Adey, Akash Kumar, Ruolan Qiu, Jay Shendure & Benjamin Hall
The genus Rhododendron (Ericaceae), which includes horticulturally important plants such as azaleas, is a highly diverse and widely distributed genus of >1,000 species. Here, we report the chromosome-scale de novo assembly and genome annotation of Rhododendron williamsianum as a basis for continued study of this large genus. We created multiple short fragment genomic libraries, which were assembled using ALLPATHS-LG. This was followed by contiguity preserving transposase sequencing (CPT-seq) and fragScaff scaffolding of a large fragment...

Soil microbial communities associated with giant sequoia: How does the world's largest tree affect some of the world's smallest organisms?

Stephen Hart, Chelsea J. Carey, Sydney I. Glassman, Thomas D. Bruns & Emma L. Aronson
Giant sequoia (Sequoiadendron giganteum) is an iconic conifer that lives in relic populations on the western slopes of the California Sierra Nevada. In these settings, it is unusual among the dominant trees in that it associates with arbuscular mycorrhizal fungi rather than ectomycorrhizal fungi. However, it is unclear whether differences in microbial associations extends more broadly to non-mycorrhizal components of the soil microbial community. To address this question, we characterized microbiomes associated with giant sequoia...

ABCB transporters in a leaf beetle respond to sequestered plant toxins

Paulina Kowalski, Michael Baum, Marcel Koerten, Alexander Donath & Susanne Dobler
Phytophagous insects can tolerate and detoxify toxic compounds present in their host plants and have evolved intricate adaptations to this end. Some insects even sequester the toxins for their defense. This necessitates specific mechanisms, especially carrier proteins that regulate uptake and transport to specific storage sites or protect sensitive tissues from noxious compounds. We identified three ATP-binding cassette subfamily B (ABCB) transporters from the transcriptome of the cardenolide-sequestering leaf beetle Chrysochus auratus and analyzed their...

Field‐based individual plant phenotyping of herbaceous species by unmanned aerial vehicle

Wei Guo, Yuya Fukano, Koji Noshita & Seishi Ninomiya
1. Recent advances in Unmanned Aerial Vehicle (UAVs) and image processing have made high-throughput field phenotyping possible at plot/canopy level in the mass grown experiment. Such techniques are now expected to be used for individual level phenotyping in the single grown experiment. 2. We found two main challenges of phenotyping individual plants in the single grown experiment: plant segmentation from weedy backgrounds and the estimation of complex traits that are difficult to measure manurally. 3....

Habitat selection of foraging male Great Snipes on floodplain meadows: importance of proximity to the lek, vegetation cover and bare ground

Michał Korniluk, Paweł Białomyzy, Grzegorz Grygoruk, Łukasz Kozub, Marcin Sielezniew, Piotr Świętochowski, Tomasz Tumiel, Marcin Wereszczuk & Przemysław Chylarecki
Drainage of wetlands and agricultural intensification has resulted in serious biodiversity loss in Europe, not least in grasslands. Consequently, many meadow birds have drastically declined, and the habitats they select for breeding currently rely on land management. However, the selection of habitats maintained by agriculture may contribute to reduced fitness and thus remain maladaptive for individuals, which makes conservation challenging. An understanding of the relationships between species’ habitat selection, food supply and land management in...
