Summary: Research suggests that slower leaf litter decomposition rates in forests dominated by ectomycorrhizal (ECM) fungi compared to arbuscular mycorrhizal (AM) fungi may be more related to litter phosphorus content rather than the mycorrhizal type. The quality of litter and environmental conditions play a significant role in the manifestation of slower decomposition rates in ECM-dominated stands.

Summary: This study investigated the impact of different fire frequencies on soil systems and found that only the A horizon was significantly affected by the prescribed fire interval manipulation. The richness and composition of microbial communities in the A horizon differed between the burned treatments and the unburned control. Soil chemistry changes were also observed in the A horizon, with higher levels of certain nutrients in the burned treatments compared to the fire exclusion treatment. The results indicate that long-term changes in fire frequencies can induce shifts in the soil microbial community.

Summary: The coastal and marine ecosystems in the unique environment of the Red Sea have adapted and flourished for millennia, providing socio-economic and environmental benefits to the bordering coastlines and countries. While the coral reef ecosystems in the Red Sea appear to be relatively healthier compared to global trends, they are still vulnerable to stressors such as increasing ocean temperature, acidification, and pollution. Degradation of marine habitats in many regions, coupled with increasing population pressure and coastal development projects, poses environmental costs and significant economic losses. Investment in blue natural capital and strategic development model focusing on the health of natural ecosystems can safeguard the sustainable development of the Red Sea.

Summary: Experimental manipulation of protozoan predation pressure in activated sludge communities had strong and positive effects on bacterial diversity components, with responses leveling off at higher predation pressure levels. While predator intensity positively impacted taxa richness, predator diversity had mixed effects on bacterial diversity. Reduction in top-down control by predators negatively affected taxa associated with treatment efficiency, particularly nitrogen removal. The study highlights distinct mechanisms linking protozoan predation with bacterial diversity and community composition in activated sludge communities.

Summary: Global biodiversity loss and mass extinction of species have become crucial environmental issues, leading to disruptions in various ecosystems and human health. Microbiome-targeted interventions, such as probiotics and microbiome transplants, are emerging as potential options to reverse biodiversity deterioration and enhance wildlife and ecosystem resilience. However, implementation of these interventions is urgently needed. This article summarizes concepts, challenges, and ethical aspects of microbiome stewardship, which involves managing ecosystem resources responsibly to restore organisms and ecosystem functions. A framework guiding the application of environmental and wildlife probiotics is proposed, with consideration of risks versus the consequences of inaction. Careful and responsible microbiome management is critical to counteract biodiversity loss, but practical and regulatory obstacles must be addressed to maximize its effectiveness.

Summary: Reef-building corals rely on symbiosis with unicellular algae for their evolutionary success, but frequent heat waves cause coral mass-bleaching events, posing a serious threat to reef ecosystems. Understanding the functioning, breakdown, and prevention of coral-algal symbiosis remains incomplete due to difficulties in experimental handling and manipulating the association. The study identifies the stony coral species Galaxea fascicularis as a novel candidate coral model system, which allows for genotype studies and experimental investigation of the symbiosis.
