Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Carbon of microbial biomass in Al-Fe-humus soils of the northwestern Russia

open access: yesБюллетень Почвенного института им. В.В. Докучаева
The study was carried out in blueberry pine forests of the middle taiga subzone of Karelia. The results of complex studies of the microbiocenosis of Al-Fe-humus soils (Albic Podzols) formed on fluvioglacial deposits are presented.

The diversity and ecological role of protozoa in fresh waters [PDF]

open access: yes, 1997
Protozoa feed on and regulate the abundance of most types of aquatic microorganisms, and they are an integral part of all aquatic microbial food webs. Being so small, aerobic protozoa thrive at low oxygen tensions, where they feed (largely unaffected by ...

High atmospheric pressure rescues plant growth under humidity stress: A model for climate‐resilient deep underground agriculture

open access: yesDeep Underground Science and Engineering, EarlyView.
High atmospheric pressure (120 kPa) in deep underground counteracts humidity‐induced physiological stress in plants, stabilizing water balance and enhancing antioxidative defenses. This synergy boosts biomass despite elevated humidity, demonstrating sustainable deep underground agriculture potential under climate uncertainty.

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra

open access: yesEcography, EarlyView.
Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.

State‐Level Politics in Forest Governance: The Role of the Narrative‐Policy Nexus in the Brazilian Amazon

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Deforestation and its social impacts are an enduring challenge in agrarian frontiers, especially in the tropics. Fueled by global demand for commodities, this process is mediated by ideas, concepts, meanings, and policies that uphold socioenvironmental degradation. A key and understudied—arena in which this mediation occurs is the sub‐national

The effect of climate and land uses on soil microbial biomass and activities [PDF]

open access: yesمجله جنگل ایران, 2019
Today, one of the major concerns in the world and Iran is land use change from forests and pastures to agricultural lands which causes soil quality mitigation and global climate change.

On the tree-root-soil-continuum - temporal and spatial coupling of the belowground carbon flux [PDF]

open access: yes, 2007
The direct flux of current assimilates from the tree canopy to the belowground compartment drives roughly half of the soil respiratory activity in boreal forests.

Scaling and balancing carbon dioxide fluxes in a heterogeneous tundra ecosystem of the Lena River Delta

open access: yes, 2019
The current assessments of the carbon turnover in the Arctic tundra are subject to large uncertainties. This problem can (inter alia) be ascribed to both the general shortage of flux data from the vast and sparsely inhabited Arctic region, as well as the

A Highly Stable Zinc‐Mimosinate Metal–Organic Framework for Controlled Agrochemical Delivery

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The graphical abstract illustrates the design of metal–organic frameworks (MOFs) as agrochemicals constructed from active building blocks. The highly robust GR‐MOF‐25 is assembled from the natural herbicide L‐mimosine and Zn2+ ions, combining herbicidal, micronutrient, and antibacterial properties.
