Small trees, big impact: Rethinking how trees and their underground partners shape their soils

Adam Weiler, Indiana University, discusses his article: Seeing the forest for all the trees: Mycorrhizal-associated nutrient economies are modulated by stem density and the synchrony between overstorey and understorey tree communities When we think about how forests influence the soil beneath them, it’s easy to picture the towering overstorey trees that define a woodland. These…

How the strategies of bilberry roots to access nutrients vary at small scales and with changes in nutrient availability

Barbara Meyers, University of Freiburg in Germany, discusses her article: Soil nutrient availability rather than spatial nutrient heterogeneity shapes the intraspecific response of root architectural, morphological and mycorrhizal traits in Vaccinium myrtillus Roots make up for a large proportion of plant biomass and play a central role in several plant functions: accessing water and nutrients…

High-altitude allies: Alpine plants and their fungal partners

Skylar Burg, University of Jyväskylä in Finland, discusses her article: Abiotic conditions along altitude shape plant-fungal associations by influencing both fungal availability and association strength Setting out in the mountains High in the mountainous tundra of Norway, Sweden, and Finland, the perennial herb Bistorta vivipara, known as alpine bistort, thrives in conditions that challenge most…

Climate and mycorrhizal type shape global plant nitrogen dynamics

Qiong Chen and Zuoqiang Yuan, Northwestern Polytechnical University in China, discuss their article: Global mycorrhizal status drives leaf δ15N patterns Nitrogen: A Vital Nutrient for Plants Nitrogen is a crucial nutrient for plants. It plays a vital role in their growth, development, and overall productivity. The availability of nitrogen is a key factor in understanding…

Do mutualist limitations hinder ectomycorrhizal tree seedling establishment in North American secondary forests?

Andrew Cortese, from Michigan State University, discusses his article: Ectomycorrhizal tree islands in arbuscular mycorrhizal forests: hotspots of fungal inoculum important for seedling establishment of historically dominant trees Present-day forests echo past disturbance history Northeastern North American forests are comprised of a mixture of arbuscular mycorrhizal (AM) and ectomycorrhizal (EM) trees. However, by the turn…

Exploring How Mycorrhiza Affect Strawberry Offspring: A Look at Sexual vs. Clonal Reproduction

Vít Latzel (@LatzelV; @IBOTCZ; @popecolIBOT), Institute of Botany of the Czech Academy of Sciences, discusses his article: Transgenerational effects of mycorrhiza are stronger in sexual than in clonal offspring of Fragaria vesca and are partly adaptive BackgroundPlants have a great capacity to adjust their phenotypes to the environment—not just during their own lifetimes, but also…

How mycorrhizal associations are growing our understanding of plant-soil feedback across plant communities

Andrew Eagar and Sara Moledor, from Michigan State University’s Department of Plant Biology, discuss their research group’s new review paper: Setting the Stage for Plant-Soil Feedback: Mycorrhizal Influences over Conspecific Recruitment, Plant and Fungal Communities, and Coevolution A holistic view of plant-soil feedback Research over the last 20 years on plant-soil interactions has greatly advanced…

Unraveling the Complex Interactions in Tallgrass Prairie Ecosystems

Eric Duell, from the Kansas Biological Survey & Center for Ecological Research, discusses his article: ‘Mycorrhizal-herbivore interactions and the competitive release of subdominant tallgrass prairie species‘ Tallgrass prairies of central and eastern North America are characterized by diverse plant communities consisting of grasses and forbs (often called wildflowers or broadleaves) which possess a variety of…

Soil fertility drives plant life down-under

Rachel Standish discusses her recent article: Mycorrhizal symbiosis and phosphorus supply determine interactions among plants with contrasting nutrient-acquisition strategies. Find out more about the importance of below-ground mechanisms for understanding factors determining community structure. The south-west region of Western Australia is a drawcard for plant nerds. Geographic isolation, a stable climate, and ‘quiet’ flat landscape…
