Plant functional trait dissimilarity drives plant mixture effects on fine root biomass and trait variations. [PDF]
New PhytolSummary Fine roots are critical for soil resource uptake, yet how declining plant diversity alters fine root biomass (RB) and traits remains unclear. We tested how plant functional trait dissimilarity in shade tolerance, drought tolerance, growth rate, and nitrogen‐fixation ability drives variation in root attributes.

Functional Ecology, Volume 37, Issue 7, Page 1948-1961, July 2023., 2023 Read the free Plain Language Summary for this article on the Journal blog. Abstract Orchid mycorrhiza forms unique symbiotic associations between members of the Orchidaceae and multiple ecological guilds of fungi. Because orchids associate with a wide variety of fungi with different ecological functions, they represent an ideal study system to address ...

Factors that shape large‐scale gradients in clonality
Journal of Biogeography, Volume 50, Issue 5, Page 827-837, May 2023., 2023 Abstract Aim Many plant species reproduce clonally. However, ecologists still have much to learn about the factors that shape large‐scale patterns in plant clonal growth and reproduction, especially in the southern hemisphere. We addressed this knowledge gap by quantifying relationships between reproductive mode and a suite of plant characteristics and

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.
