Atmospheric nitrogen (N) deposition is altering grassland productivity and community structure worldwide. Deposited N comes in different forms, which can have different consequences for productivity due to differences in their fertilization and acidification effects. We hypothesize that these effects may be mediated by changes in plant functional traits. We investigated the responses of aboveground primary productivity and community functional composition to addition of three nitrogen compounds (NH4NO3, [NH4]2SO4, and CO[NH2]2) at the rates of 0,...

Stability of elemental content correlates with plant resistance to soil impoverishment

Aims We investigated whether plant resistance to soil impoverishment would depend on their flexibility in taking up nutrients and on maintaining elemental stoichiometry. Methods We mixed sand with grassland soil in mass proportions of 0, 10, 30, 50 and 70% to simulate soil impoverishment as caused by a gradient of desertification intensity and examined how plant nitrogen (N) uptake (15NH4NO3 and NH415NO3 labelling) and nutrient stoichiometry were associated with plant growth responses of a sedge...

Defining the Syrian hamster as a highly susceptible preclinical model for SARS-CoV-2 infection

Following emergence in late 2019, SARS-CoV-2 rapidly became pandemic and is presently responsible for millions of infections and hundreds of thousands of deaths worldwide. There is currently no approved vaccine to halt the spread of SARS-CoV-2 and only very few treatment options are available to manage COVID-19 patients. For development of preclinical countermeasures, reliable and well-characterized small animal disease models will be of paramount importance. Here we show that intranasal inoculation of SARS-CoV-2 into Syrian...

Carbon allocation to the rhizosphere is affected by drought and nitrogen addition

Ruzhen Wang, Timothy Cavagnaro, Yong Jiang, Claudia Keitel, Feike Dijkstra, Timothy R. Cavagnaro & Feike A. Dijkstra
Photosynthetic carbon (C) allocated below-ground can be shared with mycorrhizal fungi in exchange for nutrients, but also added into soil as rhizodeposits that potentially increases plant nutrient supply by supporting microbial nutrient mineralization from organic matter. How water and nitrogen (N) availabilities affect plant C allocation to the rhizosphere, including both arbuscular mycorrhizal fungi (AMF) symbionts and rhizodeposits, remains largely unknown. We used a 13CO2 pulse labelling experiment to assess effects of drought and N...
