In principle, phylogenetic trees may be generated from any data set that contains phylogenetic information. This chapter, however, is confined to nucleotide and amino acid sequences. These are the most widely used sources of molecular information for phylogenetic studies of species or higher taxa such as families or orders, and the phylogeny of proteins is an important and useful pursuit in its own right. To make a tree... 

In any event, when higher taxa are examined, biodiversity is greater in the sea than on land (May 1994). This finds a parallel in a greater natural product diversity in the sea than on land at the molecular skeleton level (Part III). The reverse is true when biodiversity is considered at the species level and the actual metabolites are taken as a measure of natural product diversity (Part IV).

Build databases that contain reliable ecological background information on species or higher taxa inhabiting different types of European freshwater ecosystem. Information on traits which demonstrate sensitivity to direct and indirect effects of climate change (e.g. temperature preferences, resilience to droughts) is especially important. 

As dissolved oxygen concentrations continue to fall, less mobile organisms become stressed and move up out of the sediments, attempt to leave the seabed, and often die (Figure 5). As oxygen levels fall from 0.5 toward 0mgl , there is a fairly linear decrease in benthic infaunal diversity, abundance, and biomass. Losses of entire higher taxa are features of the... 

The degree of sequence similarity varies even more for higher taxa, i.e. between the levels of the genus and the phylum (kingdom). Consequently, it is not possible to deduce taxon affiliation of an isolate or a clone sequence on the basis of sequence similarity alone [22],...
