Ecological diversification

In this chapter it is outlined how man has exploited the signaling, defensive, and environmentally relevant metabolites. That bioactive metabolites of phylogeneticaUy distant organisms are detected by man s receptors finds rationalization in the origin of all organisms fi-om a common ancestor and the limited possibilities of diversification of receptors and biosynthetic pathways. This is why the pharmaceutical industry is interested in chemical ecology (Caporale 1995). 

As is apparent from the foregoing discussion, plants produce a huge array of natural products, many of which are specialized secondary metabolites associated with particular plant species and/or having to play important ecological roles. It is likely that for diversification and survival of the plant kingdom, individual... 

This diversification would lead to distinct types of biofilms in specific habitats—the earliest biomes. They may have been only a few microns thick, but these would have been the first complex communities the ancestors of interdependent ecologies. 

Such inherencies and analogs suggest that the motors of adaptation and ecological diversification make the emergence of complex biological systems, say an eye seeing a rose garden, probable, and perhaps even inevitable. The basic similarity...

Reliable estimates of future supplies remain difficult to obtain due to the lack of information on the ecology of new sites, the productivity of the local Artemia population, and on technical and economic studies related to accessibility, sustainable quantities, characteristics of the resource relevant to larviculture, etc. (see for example Marden et al, 2012). Diversification of resources remains a most important issue, along with the further rationalization of the use of Artemia. As a net result of all the factors that play on the aquaculture market, the global demand for cysts, currently -2500-3000 tons/year, is expected to increase further. China is the main consumer (and will continue to be so) with an annual consumption of -1500 tons, of which about one half is imported from Russia and Kazakhstan and the other half produced domestically (mainly from inland lakes Bohai Bay has had a relatively stable production over the past years of about 400 tons of raw product).

Ecological/architectural diversification is the most common. When it is applied to the software, it is important that the diversificahon of architecture is evident, ensuring that different software will not have the same defects.
