Summary: The structure and function of the endolithic microbiome in corals are linked to bleaching susceptibility. Corals that are resistant to bleaching have endolithic microbiomes with greater functional diversity and redundancy, and lower endolithic primary productivity, possibly due to the dominance of chemolithotrophs. Lower primary production within the skeleton may help maintain nutrient-limiting conditions in the coral-algal symbiosis under heat stress.

Summary: In this study, it was found that habitat fragmentation alone did not affect the gut microbiome of wildlife, but the microbiomes of individuals living in fragmented forests affected by anthropogenic disturbances showed a shift in community composition and structure, with a higher likelihood of containing microbiota associated with domesticated animals and their pathogens.

Africa possesses significant genetic diversity in its ecosystems, humans, and animals. In this Comment, we address the lack of available microbiome datasets from Africa and suggest measures to promote microbiome research in the region.

Summary: In this study, the tissue metabolomes and microbiomes of corals, macroalgae, and crustose coralline algae were characterized, and associations between microbial taxa and metabolites specific to different hosts were defined. The results showed that both tissue metabolomes and microbiomes had host specificity at both the phylum and genus level. There were distinct differences in microbiomes and metabolomes between calcifiers (corals and CCA) and erect macroalgae. The study also highlighted common lipid-based immune response pathways across different host organisms.

Summary: Skin is a complex organ that acts as a critical barrier and regulator in interactions between the human body and its environment. Recent studies have revealed the significant role of microbial communities in maintaining the health and function of the skin and immune system. Various factors influence the composition and diversity of these communities on the skin, and specific changes in skin microbiota have been linked to the development of chronic diseases. Standardized practices in studying skin microbial communities can enhance our understanding of their structures, functions, and associations with health.

Summary: Temperature has a significant impact on the adaptation and composition of microbiomes, and their enzymes play a crucial role in the thermal response. This study demonstrates that enzyme thermal properties not only explain microbial thermal plasticity but are also finely tuned by the thermal variability of the environment. The findings highlight the importance of temperature-driven enzyme selection in shaping microbiome thermal plasticity and emphasize the need to consider thermal variability in addition to mean annual temperature in understanding microbial community response to temperature.

Summary: Sustainable cropping systems need to be both stable and resilient to erratic and extreme climate conditions, while also remaining profitable and providing critical ecosystem services. The study found that perennial and diverse cropping systems showed higher productivity and better stability in the face of drought, with soil health indicators positively correlated with both stability and perenniality. More diverse cropping systems exhibited greater resilience to disturbances, emphasizing the necessity of promoting perennial and diverse cropping systems for sustainable food production under increasingly erratic climate patterns.

Summary: The question of whether large-scale geographical patterns in diversity observed for macroorganisms also apply for their microbiomes and whether microbiomes are shaped by the same processes that appear key for determining biogeographical patterns in their hosts remains largely unknown. This article discusses challenges and potential approaches for studying microbiome biogeography, with a focus on bacterial microbiomes, and provides an overview of host-associated bacterial microbiome research examining classic biodiversity patterns in ecology and evolution.

Summary: This study demonstrates that moth defoliation has far-reaching consequences on soil food webs, leading to increased diversity and structural differences in soil food webs. After moth outbreaks, certain trophic groups experienced declines in diversity and relative abundance, while others expanded, resulting in increased belowground diversity at different trophic levels. A holistic view of ecosystems is crucial for understanding the cascading effects of major disturbances on soil food webs.

Summary: The aim of this study was to investigate the potential of heterogeneous composite cross populations (CCPs) to increase sustainability and resilience of wheat cropping systems. The results showed that under organic conditions, CCPs had similar yields to commercial cultivars and higher yields than inbred lines, while under conventional conditions, conventionally-bred cultivars had higher yields. The CCPs exhibited higher yield stability and foliar disease resistance compared to commercial cultivars and inbred lines due to their high genetic diversity. The CCPs also showed differences in morphological and phenological traits, indicating adaptation to environmental conditions through natural selection.

Summary: The survey conducted in Germany from 2016-2019 evaluated the effects of management systems, pedo-climatic conditions, and crop rotation history on faba bean root health, diversity of root rot pathogens, and yield. Results showed that there was no significant difference in root rot incidence between organic and conventional fields, but rotational history had an impact on the isolation frequencies of certain species. Pedo-climatic conditions favored the most prevalent Fusarium species identified in the study.

Summary: Conservation tillage in organic farming systems has potential effects on the physical and mechanical properties of the soil. This study evaluated the impact of different conservation management treatments on the soil's physical quality in an organic field trial. The reduced-tillage systems showed lower total porosity, air capacity, and higher bulk density compared to plowing treatments, with enhanced soil aggregate stability. However, overall, the reduced-tillage treatments did not negatively affect the critical physical values or functionality of the soil, demonstrating its feasibility for sustainable organic farming.

This study estimates the burden of foodborne diseases caused by specific hazards in two African countries and attributes them to specific foods. The results show that Campylobacter and Salmonella are the main pathogens, and the burden of meat is higher than that of vegetables.

Summary: This study investigated fungal strains isolated from eggs of the cereal cyst nematode Heterodera filipjevi and roots of Microthlaspi perfoliatum. The strains were found to belong to a distinct lineage closely related to Equiseticola and Ophiosphaerella. Pathogenicity tests demonstrated that the fungus could parasitize its original nematode host as well as the sugar beet cyst nematode H. schachtii. The fungus also showed the ability to colonize the roots of wheat and produce melanized hyphae.

By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
