[Show abstract] [Hide abstract] ABSTRACT: Computing the phylogenetic diversity of a set of species is an important part of many ecological case studies. More specifically, let \(\mathcal {T}\) be a phylogenetic tree, and let R be a subset of its leaves representing the species under study. Specialists in ecology want to evaluate a function \(f(\mathcal {T},R)\) (a phylogenetic measure) that quantifies the evolutionary distance between the elements in R.

An open market purchase means that the FOMC is putting cash into the marketplace and taking bonds away. A key item to understand is this increase in cash may be temporary or permanent. The Fed is constantly adjusting the money supply for the season effects of demand for cash.o the Fed increases money supply by buying back bonds and it decreases money supply by selling them. If the Fed buys from you, you have more money. If you buy from the Fed, you have less money. Chris Â· 8 years ago.
