This study examined the sterol compositions of 102 dinoflagellates using clustering and cluster validation techniques, as a means of determining the relatedness of the organisms. In addition, dinoflagellate sterol-based relationships were compared statistically to 18S rDNA-based phylogenetic relationships using the Mantel test. Our results indicated that the examined dinoflagellates formed six ...

General equilibrium theory (GET) took the entire edifice of economic theory by storm during the 1950s. Its elegant existence theorems, proved by, among others, Kenneth Arrow and Gerard Debreu (1954) and Lionel McKenzie (1959), provided a framework of analysis that made more precise and sound the main intuitions of the neoclassical school. An even more important consequence of these developments...

Ectomycorrhizal fungal (EMF) communities are highly diverse at the stand level. To begin to understand what might lead to such diversity, and to improve sampling designs, we investigated the spatial structure of these communities. We used EMF community data from a number of studies carried out in seven mature and one recently fire-initiated forest stand. We applied various measures of spatial p...
