چکیده

Mycorrhizal associations, by which most land plants receive mineral nutrition, are diffuse and often non-specific. A common mycorrhizal network is formed when fungal mycelia colonize and link together the roots of two or more plants, sometimes of different species. Here, we discuss recent work showing how, under realistic ecological conditions, such networks can affect the physiology and ecology of plants by facilitating interplant nutrient exchange, acting as inoculum reservoirs for seedlings and altering plant competitive abilities. Although mechanisms for their evolutionary emergence remain unclear, investigating mycorrhizal networks profoundly modifies our understanding of plant communities.

This paper shows that a financial network can be most resilient for intermediate levels of risk diversification, and not when this is maximal, as generally thought so far. This finding holds in the presence of th...

Previous research in the field of authorship attribution has shown that the writing style of an author can be characterized and distinguished from that of other authors automatically. In this paper we take a look at the less approached problem of how the styles of different characters can be di...

Rational Choice in Love

I WANT TO FOCUS ON A SINGLE WORK OF LITERATURE. It is not directly concerned with war among states, though its author, Choderlos de Laclos, was in fact a soldier, an artillery officer, and an expert in fortifications. It deals with other kinds of war. My goal today is to consider the place of reason—of rational choice in the commonsense version of this term—and, specifically, of rational choice...

The endothelin system in pulmonary and renal vasculopathy: les liaisons dangereuses.

Endothelial cells regulate vascular tone largely by the actions of endothelin-1. Endothelin-1 is a potent vasoconstrictor, with effects that are dependent on the receptors to which it binds as well as their location. Endothelin-1 dysregulation is implicated in pathological conditions, including those of the pulmonary vasculature and the kidney. In this review, we describe the physiology and act...
