Ant and plant diversity respond differently to seed‐based prairie restoration

Burning reveals cryptic plant diversity and promotes coexistence in a California prairie restoration experiment

Grassland and prairie restoration projects in California often result in long-term establishment of only a few native plant species, even when they begin with a diverse seed palette. One explanation for the disappearance of certain native species over time is that they are excluded through competition. If so, management that reduces interspecific competition may favor ‘‘subordinate’’ natives an...

Arbuscular mycorrhizal fungi respond to increasing plant diversity

The effect of plant diversity (1, 2, 8, or 16 species) on arbuscular mycorrhizal fungi (AMF) was assessed at the Cedar Creek Long-Term Ecological Research site at East Bethel, Minnesota, from 1997 to 1999. At each of the five samplings, AMF in 16-species plots produced from 30 to 150% more spores and from 40 to 70% greater spore volumes than AMF in one-species plots. Regressions of spore number...

Bouncing Back: Plant-Associated Soil Microbes Respond Rapidly to Prairie Establishment

It is well established that soil microbial communities change in response to altered land use and land cover, but less is known about the timing of these changes. Understanding temporal patterns in recovering microbial communities is an important part of improving how we assess and manage reconstructed ecosystems. We assessed patterns of community-level microbial diversity and abundance in corn...

Nitrogen Remobilization and N-P-K Concentration of Wheats of Different Ploidy Levels Respond Differently to Nitrogen Supply

Relationship of nitrogen (N) supply to nitrogen remobilization and leaf and grain P, K, and N status of wheat lacks clarity. The present pot experiment was conducted to evaluate nitrogen remobilization and leaf and grain P, K, and N status of ancient wheats of different ploidy levels in response to nitrogen. The experiment was carried out in Fall 2017-Spring 2018 at the Isfahan University of Te...
