Feedback in the plant-soil system
TL;DR: In this article, the authors review the mechanistic basis and assess the evidence that feedback occurs between plants and the soil and find that the evidence of feedback is strongest for plants growing in extreme environments and for plant-mutualist or plant-enemy interactions.

Abstract: ▪ Abstract Feedback between plants and the soil is frequently invoked on the basis of evidence of mutual effects. Feedback can operate through pathways involving soil physical properties, chemical and biogeochemical properties and processes, and biological properties, including the community composition of the microbiota and soil fauna. For each pathway, we review the mechanistic basis and assess the evidence that feedback occurs. We suggest that several properties of feedback systems (for example, their complexity, specificity, and strength relative to other ecological factors, as well as the temporal and spatial scales over which they operate) be considered. We find that the evidence of feedback is strongest for plants growing in extreme environments and for plant-mutualist or plant-enemy interactions. We conclude with recommendations for a more critical appraisal of feedback and for new directions of research. Let us not make arbitrary conjectures about the greatest matters. Heraclitus (1)

Influence of Trees Species on Nutrient Availability in the Forest Ecosystem
Anietie Godwin Ezekiel,Omodot Timothy Umoh,Justina Cosmos Ataekong,Victoria Enoh Uyoh,Augustine Ochuko Oghenekevwe +4 more
TL;DR: In this paper , the influence of tree species on the availability of nutrients in the forest ecosystem was assessed using a quadrats size of 10 m x 10 m spaced at regular intervals of 20 m. Soil samples were collected from the sampled plots closer to the base of the species using a soil auger at a depth (0-30 cm).

Comparative impacts of aboveground and belowground enemies on an invasive thistle
30 Jan 2023
TL;DR: This article performed a reciprocal transplant experiment to test the relative impacts of above-ground and belowground interactions at three sites across a 509-km latitudinal gradient in its invaded range in Ontario, Canada, at each site, C. arvense seedlings were protected with above-and/or belowground exclosures in a factorial design.

The vertical distribution of soil organic carbon and its relation to climate and vegetation
TL;DR: In this paper, the authors examined the association of soil organic carbon (SOC) content with climate and soil texture at different soil depths, and tested the hypothesis that vegetation type, through patterns of allocation, is a dominant control on the vertical distribution of SOC.

Acceleration of global warming due to carbon-cycle feedbacks in a coupled climate model
TL;DR: Results from a fully coupled, three-dimensional carbon–climate model are presented, indicating that carbon-cycle feedbacks could significantly accelerate climate change over the twenty-first century.
Mycorrhizal fungal diversity determines plant biodiversity, ecosystem variability and productivity
Marcel G. A. van der Heijden,John N. Klironomos,Margot Ursic,Peter Moutoglis,R. Streitwolf-Engel,Thomas Boller,Andres Wiemken,Ian R. Sanders +7 more
TL;DR: It is shown that below-ground diversity of arbuscular mycorrhizal fungi (AMF) is a major factor contributing to the maintenance of plant biodiversity and to ecosystem functioning, and that microbial interactions can drive ecosystem functions such as plant biodiversity, productivity and variability.
Predicting changes in community composition and ecosystem functioning from plant traits: revisiting the Holy Grail
Sandra Lavorel,Eric Garnier +1 more
TL;DR: A framework using concepts and results from community ecology, ecosystem ecology and evolutionary biology to provide a linkage between traits associated with the response of plants to environmental factors and traits that determine effects of plants on ecosystem functions is presented.
The Mineral Nutrition of Wild Plants Revisited: A Re-evaluation of Processes and Patterns
Rien Aerts,F. S. Chapin +1 more
TL;DR: The issues of nutrient-limited plant growth and nutrient uptake, with special emphasis on the importance of the uptake of nutrients in organic form—both by mycorrhizal and by non-mycorrhIZal plants—and the influence of symbiotic nitrogen fixation are treated.
