Root functional traits explain root exudation rate and composition across a range of grassland species

Alex Williams, Holly Langridge, Angela L. Straathof, Howbeer Muhamadali, Katherine A. Hollywood, Royston Goodacre, Franciska T. de Vries

Summary: Plant root exudation is a crucial means of communication between plants and soil microbes, impacting rhizosphere processes and ecosystem responses to changing environmental conditions. Differences in root exudate quantity and quality among plant species are influenced by plant functional group and traits such as root diameter, root tissue density, and root nitrogen content. Higher rates of root exudation were linked to traits indicative of exploitative growth and resource outsourcing, providing insights into species-specific differences and the role of root exudates in the resource-outsourcing strategy.

The Unseen Effects of Deforestation: Biophysical Effects on Climate

Deborah Lawrence, Michael Coe, Wayne Walker, Louis Verchot, Karen Vandecar

Summary: Climate policy has mainly focused on carbon stocks and sequestration in forests, neglecting the impact of changes in forest cover, structure, and composition on biophysical processes and climate effects. This study highlights the importance of evaluating the combined net climate impact of carbon and biophysical effects in different latitudes. Results show that tropical deforestation leads to global warming, while at mid-latitudes, deforestation causes modest warming due to released forest carbon outweighing biophysical cooling. Beyond 50 degrees N, large-scale deforestation leads to net global cooling mainly driven by biophysical processes. Forests play a crucial role in mitigating global climate change and promoting local climate stability.

Effects of fragmentation on grassland plant diversity depend on the habitat specialization of species

Yongzhi Yan, Scott Jarvie, Qingfu Liu, Qing Zhang

Summary: This study evaluated the impacts of habitat loss and fragmentation on grassland plant species richness in the agro-pastoral ecotone of northern China. The results showed that habitat loss had a negative effect on overall species richness and grassland specialist richness, but a positive effect on weed richness. Additionally, the increase in patch density caused by habitat loss had a positive effect on overall species richness and grassland specialist richness. These findings highlight the importance of adding habitat patches in fragmented landscapes for conserving habitat specialists.

Deconstructing the microbial necromass continuum to inform soil carbon sequestration

Kate M. Buckeridge, Courtney Creamer, Jeanette Whitaker

Summary: Looking at the necromass continuum, three conclusions are drawn for future research. Firstly, controls on necromass persistence become clearer when viewed through the continuum's lens; secondly, destabilization is the least understood stage with recycling also insufficiently evidenced in many ecosystems; and thirdly, the response of necromass process rates to climate change remains unresolved for most continuum stages and ecosystems.

Microplastic fiber and drought effects on plants and soil are only slightly modified by arbuscular mycorrhizal fungi

Anika Lehmann, Eva F. Leifheit, Linshan Feng, Joana Bergmann, Anja Wulf, Matthias C. Rillig

Summary: The study reveals that microplastics in soil can affect the plant-soil system by promoting plant growth and favoring key root symbionts, AM fungi. However, microplastics still have a negative effect on soil aggregates, counteracting the positive influence of plant roots and AM fungi on soil aggregation. Concerns about microplastics interacting with other factors of global change were not observed in relation to drought.

Clarifying the evidence for microbial- and plant-derived soil organic matter, and the path toward a more quantitative understanding

Emily D. Whalen, A. Stuart Grandy, Noah W. Sokol, Marco Keiluweit, Jessica Ernakovich, Richard G. Smith, Serita D. Frey

Summary: To predict and mitigate changes in soil carbon stocks, understanding the factors regulating soil organic matter formation and persistence is crucial. Recent studies have emphasized the dominance of microbial-derived organic matter inputs, but others have challenged this view, suggesting larger contributions from plants. However, methodological limitations introduce uncertainty into quantifying plant- and microbial-derived SOM. It is important to re-evaluate methods, define their limitations, and improve quantification strategies.

Summary: Habitat selection is a fundamental animal behavior that affects a wide range of ecological processes. Technological and methodological advances in the past 20 years have led to a surge in studies addressing this process, but there is a lack of guidance on best analytical practices. This paper provides a non-technical overview and synthesis of literature on habitat-selection analyses, aiming to clarify the complex literature while serving as a reference and best practices guide for practitioners.

Summary: The priming effect (PE) is a key mechanism contributing to the carbon balance of the soil ecosystem. Recent research has shown increased interest in understanding and studying this mechanism. Although there are still gaps in knowledge, progress has been made in deciphering the non-biological mechanisms underlying PE and identifying the microbial actors involved. However, including PE into mechanistic models remains challenging as the mechanisms are not fully understood.
