Data from: Tree genetics strongly affect forest productivity, but intraspecific diversity-productivity relationships do not

Numerous studies have demonstrated biodiversity–productivity relationships in plant communities, and analogous genetic diversity–productivity studies using genotype mixtures of single species may show similar patterns. Alternatively, competing individuals among genotypes within a species are less likely to exhibit resource-use complementarity, even when they exhibit large differences in their effects on ecosystem function. In this study, we test the impact of genotype diversity and genetic identity on ecosystem function using an ecosystem-scale common garden experiment. Distinct tree...

Data from: Combining citizen science species distribution models and stable isotopes reveals migratory connectivity in the secretive Virginia rail

Auriel M. V. Fournier, Alexis R. Sullivan, Joseph K. Bump, Marie Perkins, Mark C. Shieldcastle & Sammy L. King
Stable hydrogen isotope (δD) methods for tracking animal movement are widely used yet often produce low resolution assignments. Incorporating prior knowledge of abundance, distribution or movement patterns can ameliorate this limitation, but data are lacking for most species. We demonstrate how observations reported by citizen scientists can be used to develop robust estimates of species distributions and to constrain δD assignments. We developed a Bayesian framework to refine isotopic estimates of migrant animal origins conditional...

Data from: The influence of plant defensive chemicals, diet composition, and winter severity on the nutritional condition of a free-ranging, generalist herbivore

Grace L. Parikh, Jennifer Sorensen Forbey, Brecken Robb, Rolf O. Peterson, Leah M. Vucetich & John A. Vucetich
When consuming plants, herbivores must deal with both low nutritional quality from cell wall constituents and potentially toxic plant secondary metabolites, which are often inversely related. Herbivores that consume a highly nutritious, but chemically defended plant, may consume high levels of toxins that require energy for detoxification. Alternatively, herbivores may avoid consuming high levels of toxins by consuming a diverse diet that may be lower in overall nutritional quality. In this study, we assessed the...

Data from: Nutrient release from moose bioturbation in aquatic ecosystems

Joseph K. Bump, Brenda G. Bergman, Amy J. Schrank, Amy M. Marcarelli, Evan S. Kane, Anita C. Risch & Martin Schütz
While the ecological importance of bioturbation is well recognized and the prevalence of aquatic foraging by terrestrial ungulates is increasingly appreciated, research linking how terrestrial ungulates function as disturbance mechanisms via bioturbation in freshwater systems is lacking. The purpose of this study was to quantify potential nutrient pulses released from benthic sediments into the water column when moose Alces alces feed on aquatic plants. We also determined if we could experimentally mimic the benthic disturbance...

Data from: MycoDB, a global database of plant response to mycorrhizal fungi

V. Bala Chaudhary, Megan A. Rúa, Anita Antoninka, James D. Bever, Jeffery Cannon, Ashley Craig, Jessica Duchicela, Alicia Frame, Monique Gardes, Catherine Gehring, Michelle Ha, Miranda Hart, Jacob Hopkins, Baoming Ji, Nancy Collins Johnson, Wittaya Kaonongbua, Justine Karst, Roger T. Koide, Louis J. Lamit, James Meadow, Brook G. Milligan, John C. Moore, , Bridget Piculell, Blake Ramsby … & Jason D. Hoeksema
Plants form belowground associations with mycorrhizal fungi in one of the most common symbioses on Earth. However, few large-scale generalizations exist for the structure and function of mycorrhizal symbioses, as the nature of this relationship varies from mutualistic to parasitic and is largely context-dependent. We announce the public release of MycoDB, a database of 4,010 studies (from 438 unique publications) to aid in multi-factor meta-analyses elucidating the ecological and evolutionary context in which mycorrhizal fungi...

Imaging the Upper Crust at Newberry Volcano using Large offset Reflections

, &
This experiment deployed a temporary seismic array of 81 L22 sensors across Newberry Volcano to record wide-agle refractions and reflections off of the geophysically-identified magma body underlying the volcano. Newberry is a large, recently active volcano that is most likely underlain by a shallow magma chamber; characterizing the size, depth, and percentage of melt in a magma rich volume is critical for assessing the hazard posed by a volcano.

Data from: An Avida-ED digital evolution curriculum for undergraduate biology

James J. Smith, Wendy R. Johnson, Amy M. Lark, Louise S. Mead, Michael J. Wiser & Robert T. Pennock
We present an inquiry-based curriculum based on the digital evolution platform Avida-ED (http://​avida-ed.​msu.​edu). We designed an instructional sequence and lab book consisting of an introduction to Avida-ED and a set of three lessons focused on specific evolutionary concepts. These served to familiarize students with experimental evolution and Avida-ED. Students then developed independent Avida-ED research projects to test their own questions. Curriculum design and implementation occurred over the course or two semesters, with a pilot implementation...
