Like many species, the model plant Arabidopsis thaliana exhibits multiple different life histories in natural environments. We grew mutants impaired signaling pathways field experiments across species' native European range order to dissect mechanisms underlying this variation. Unexpectedly, mutational loss at loci implicated cold requirement for flowering had little effect on history except late-summer cohorts. A genetically informed photothermal of progression toward explained most...
Overwhelming evidence demonstrating the benefits of active-learning pedagogy has led to a shift in teaching that requires students interact more classroom. To date, few studies have assessed whether there are gender-specific differences participation science, technology, engineering, and mathematics (STEM) courses, fewer looked across different types classroom participation. Over two semesters, we observed an introductory biology course at large research-intensive university categorized...
Abstract Selection on quantitative trait loci ( QTL ) may vary among natural environments due to differences in the genetic architecture of traits, environment‐specific allelic effects or changes direction and magnitude selection specific traits. To dissect environmental life history across climatic regions, we grew a panel interconnected recombinant inbred lines RIL s) Arabidopsis thaliana four field sites its native European range. For each environment, mapped for growth, reproductive...
Abstract Interactions with microbial symbionts have yielded great macroevolutionary innovations across the tree of life, like origins chloroplasts and mitochondrial powerhouses eukaryotic cells. There is also increasing evidence that host‐associated microbiomes influence patterns microevolutionary adaptation in plants animals. Here we describe how microbes can facilitate to test for differentiate between two main mechanisms by which produce adaptive responses higher organisms:...
Abstract As science, technology, engineering, and mathematics (STEM) classrooms in higher education transition from lecturing to active learning, the frequency of student interactions class increases. Previous research documents a gender bias participation, with women participating less than would be expected on basis their numeric proportions. In present study, we asked which attributes learning environment contribute decreased female participation: abundance in-class interactions,...
Abstract Plant‐root‐associated microbes influence plant phenotype and tolerance to environmental stress, thus have been hypothesized play a role in local adaptation. Here, we test this hypothesis with factorial experiments addressing the of adaptation Hypericum perforatum (St. John’s wort) stressful limestone barrens (alvars) compared neighboring old‐fields. Alvar plants benefited more from early life history stages, while at later growth alvar old‐field equally but only habitat. Patterns...
Abstract Switchgrass ( Panicum virgatum L.), as a dedicated bioenergy crop, can provide cellulosic feedstock for biofuel production while improving or maintaining soil quality. However, comprehensive evaluations of how switchgrass cultivation and nitrogen (N) management impact plant parameters remain incomplete. We conducted field trials in three years (2016–2018) at six locations the North Central Great Lakes Region to evaluate effects cropping systems (switchgrass, restored prairie,...
Premise of research. Plants in natural and agricultural systems are influenced myriad ways by their microbial communities, particularly providing goods services that change plant functional traits. Microbes considered an influential part the environmental context trait expression, but often, microbe-mediated effects contingent on local resources, such as nitrogen. Here, we ask how microbes nitrogen affect belowground traits patterns phenotypic selection.Methodology. We performed a fully...
Less than 1% of native prairie lands remain in the United States. Located eastern Washington, rare habitat called Palouse was largely converted to wheat monocropping. With this conversion came numerous physical, chemical, and biological changes soil that may ultimately contribute reduced yields. Here, we explored how (
In savanna ecosystems, mound-building termites and ungulate herbivores profoundly affect the abundance diversity of aboveground organisms. Yet, surprisingly little is known about how these two groups interact to impact belowground communities. Using Kenya Long-term Exclosure Experiment (KLEE), where have been excluded for over 15 years, we examined presence herbivore exclusion affected species richness, community composition, infectivity arbuscular mycorrhizal fungi (AMF). We also measured...

ABSTRACT We present the genomes of two Microvirga isolates isolated from nodules found on Medicago lupulina herbarium specimens at Marion Ownbey Herbarium Washington State University. These and others offer an unprecedented opportunity to study bacterial evolution plant-associated microbes over long time scales.

Abstract Aims Saint John’s wort, Hypericum perforatum , is a medicinally and ecologically important perennial plant species that has broad global distribution. Despite the species’ importance, little known about factors structure its microbial communities identity of microbes enhance growth fitness. Here we aim to describe associated with elucidate these communities. Methods We collected H. root samples in three adjacent habitat types: wet dry alvars (two types limestone barren) fallow...
