Soils are self-organized ecological systems within which organisms interact within a nested suite of discrete scales. Microorganisms form communities and physical structures at the smallest scale (microns), followed by the community of their predators organized in microfoodwebs (tens of microns), the functional domains built by ecosystem engineers (centimeters to meters), ecosystems, and landscapes. Ecosystemengineers, principally plant roots, earthworms, termites, and ants, play key roles in creating habitats for other organisms and controlling their activities through physical and biochemical processes. The biogenic, organic, and organomineral structures that they produce accumulate in the soil space to form threedimensional mosaics of functional domains, inhabited by specific communities of smaller organisms (microfauna and mesofauna, microorganisms) that drive soil processes through specific pathways. Ecosystem engineers also produce signaling and energy-rich molecules that act as ecological mediators of biological engineering processes. Energy-rich ecological mediators may selectively activate microbial populations and trigger priming effects, resulting in the degradation, synthesis, and sequestration of specific organic substrates. Signalingmolecules informsoil organisms of their producers? respective presences and change physiologies by modifying gene expression and through eliciting hormonal responses. Protection of plants against pests and diseases is largely achieved via these processes. At the highest scales, the delivery of ecosystem services emerges through the functioning of self-organized systems nested within each other. The integrity of the different subsystems at each scale and the quality of their interconnections are a precondition for an optimum and sustainable delivery of ecosystem services. Lastly, we present seven general research questions whose resolution will provide a firmer base for the proposed conceptual framework while offering new insights for sustainable use of the soil resource.

Abstract: The concentration of CO2 in the atmosphere has been increasing significantly since the Industrial Revolution. Because of the potential impacts of the increase in CO2 from the air on the various pathosystems, assays were carried out in a controlled environment to check the effects of elevation of the concentration of CO2 from the air on Cylindrocladium candelabrum in detached leaves and seedlings of Eucalyptus urophylla. In three trials, detached leaves were wrapped in plastic trays with foam moistened with concentration of 607 ± 86, 705 ± 105, 855 ± 152 and 1101 ± 305 micromol mol-1 CO2 from the air, sprayed with conidia of the pathogen (2 × 105 conidia ml-1) and maintained at 28 ± 1.7 oC and photoperiod of 12 h for 21 days. It was evaluated the severity of leaf spot and the sporulation of the pathogen. In both experiments with seedlings of eucalyptus, the seedlings were grown in plastic tubes, kept in plastic boxes containing vermiculite at the bottom and kept in concentrations of 451 ± 35 (control), 645 ± 118, 904 ± 116, 1147 ± 216 micromol mol-1 CO2 per 30 days for acclimatization. After this period, the seedlings were sprayed with conidia of the pathogen and kept on the same conditions for six days. It was evaluated the incidence of lesioned leaves, leaf spot severity and the number of leaves containing spores of the pathogen. The height of the seedlings, the diameter of the stem and the weight of the dry matter of the aerial part and root were also evaluated. In the tests with detached leaves, the increase of CO2 concentration had no effect on the severity of leaf spot and sporulation of the pathogen. In seedlings, the elevation of CO2 concentration decreased the incidence of leaves lesioned, the severity of the disease and the number of leaves containing spores of the pathogen when compared to the control.
