Microbial drivers of root plasticity. [PDF]

New Phytol
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

Seasonality regulates the structure and biogeochemical impact of ectomycorrhizal fungal communities across environmentally divergent neotropical dry forests

Journal of Ecology, Volume 111, Issue 8, Page 1598-1613, August 2023., 2023
These results highlight the importance of seasonality and plant community composition in shaping different aspects of SDTF ECM fungal community structure and diversity as well as the potential for both the plant and fungal components of ECM symbioses to impact soil functioning across heterogenous SDTFs.

Functional diversity of experimental annual plant assemblages drives plant responses to biological soil crusts in gypsum systems

Functional Ecology, Volume 37, Issue 3, Page 488-503, March 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Biological soil crusts (BSC) are complex biotic aggregates comprised of lichens, cyanobacteria, algae and other micro‐organism that are known to differently affect plant development along life cycle by selecting plant functional traits based on species‐specific effects.

Plant chemical diversity and its frequency have distinct but complementary effects on insect foraging

Journal of Applied Ecology, Volume 59, Issue 5, Page 1362-1371, May 2022., 2022
Whereas previous work investigates how the amount of chemical diversity in a plant population influences insect ecology, our results indicate that local spatial distribution of diversity is equally important. A key implication of this work is the potential to design cultivar mixtures spatially, at the movement scale of target organisms, to create more ...

Structural and compositional dimensions of phytochemical diversity in the genus Piper reflect distinct ecological modes of action

Journal of Ecology, Volume 110, Issue 1, Page 57-67, January 2022., 2022
Crude extract 1H NMR diversity synthesizes the compositional diversity and structural complexity of phytochemical mixtures. Plants can develop chemical diversity through different combinations of structural and compositional biosynthetic mechanisms; thus, methods incorporating both dimensions of phytochemical diversity can provide new theoretical ...

Variation in biomass allocation and root functional parameters in response to fire history in Brazilian savannas

Journal of Ecology, Volume 109, Issue 12, Page 4143-4157, December 2021., 2021
Fire stimulated the increase of absorptive root biomass in the upper soil layer in response to the higher demand for below‐ground resources, but did not promote modification of morphological root parameters. Differences in morphological root parameters reflected variation in soil properties, especially soil P, as well as differences in graminoid ...
