TL;DR: In this article, a comprehensive analysis of invertebrate activities shows that they may be the best possible indicators of soil quality, and they should also be considered as a resource that needs to be properly managed to enhance ecosystem services provided by agro-ecosystems.

TL;DR: A number of hypotheses which could be tested to explore the relationships between agricultural intensification, biodiversity in tropical soils and ecosystem functions are proposed and a conceptual framework within which such hypotheses can be tested is provided.

TL;DR: This chapter illustrates the functional classification of soil organisms based on their adaptive strategies and suggests that the three systems defined, operate at nested scales of time and space and have decreasing overall effects on the determination of soil function in the order micro-foodwebs.
Abstract: Publisher Summary This chapter helps in understanding the role of soil fauna in soil function. Soils host an extremely diverse community of invertebrates that differ in their adaptive strategies and hence in the functions they fulfill in soils. The chapter illustrates the functional classification of soil organisms based on their adaptive strategies. Three major groups of invertebrates may be defined based on the nature of the relationship that they develop with soil microflora. The microfauna comprise invertebrates of less than 0.2 mm on an average, makes use of micro-organisms mainly through predation in micro-foodweb systems. Mesofauna and large arthropods comprise the group of litter transformers. Earthworms, termites and, to a lesser extent, ants, are “ecosystem engineers” that create diverse organo-mineral structures. It is suggested that the three systems defined, operate at nested scales of time and space and have decreasing overall effects on the determination of soil function in the order micro-foodwebs

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.
Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: Understanding this complexity, while taking strong steps to minimize current losses of species, is necessary for responsible management of Earth's ecosystems and the diverse biota they contain.
Abstract: Humans are altering the composition of biological communities through a variety of activities that increase rates of species invasions and species extinctions, at all scales, from local to global. These changes in components of the Earth's biodiversity cause concern for ethical and aesthetic reasons, but they also have a strong potential to alter ecosystem properties and the goods and services they provide to humanity. Ecological experiments, observations, and theoretical developments show that ecosystem properties depend greatly on biodiversity in terms of the functional characteristics of organisms present in the ecosystem and the distribution and abundance of those organisms over space and time. Species effects act in concert with the effects of climate, resource availability, and disturbance regimes in influencing ecosystem properties. Human activities can modify all of the above factors; here we focus on modification of these biotic controls. The scientific community has come to a broad consensus on many aspects of the re- lationship between biodiversity and ecosystem functioning, including many points relevant to management of ecosystems. Further progress will require integration of knowledge about biotic and abiotic controls on ecosystem properties, how ecological communities are struc- tured, and the forces driving species extinctions and invasions. To strengthen links to policy and management, we also need to integrate our ecological knowledge with understanding of the social and economic constraints of potential management practices. Understanding this complexity, while taking strong steps to minimize current losses of species, is necessary for responsible management of Earth's ecosystems and the diverse biota they contain.
