Philosophy of Ecology (Handbook of the Philosophy of Science, Volume 11)

The main urgent difficulties dealing with humanity at the present time - over-population, power shortages, weather swap, soil erosion, species extinctions, the chance of epidemic affliction, the specter of conflict that can smash the entire hard-won earnings of civilization, or even the hot fibrillations of the inventory marketplace - are all ecological or have a wide ecological part.

Ice Age Southern Andes: A Chronicle of Paleoecological Events

The Southern Andes, stretching from the subtropics to the subantarctic, are preferably positioned for palaeoenvironmental study. Over the huge and non-stop latitudinal quantity of the cordillera (-24˚), plants is adjusted to climatic gradients and atmospheric movement styles. against the present Southern Westerlies, the Southern Andes are located to obtain the brunt of the winds, whereas biota are set to list the moving of incoming hurricane platforms over the years.

The Ecology of Bruchids Attacking Legumes (Pulses): Proceedings of the International Symposium held at Tours (France), April 16–19, 1980

As editor of this quantity it's not that i am going to stress the commercial im­ portance of the Bruchids of pulses, nor how helpful it's to understand the stipulations of infestation of vegetation that allows you to in attaining a good defense; either issues are testified by way of F. A. O. 's sponsorship, in addition to of the overseas association for organic keep an eye on.

Sample text

The natural population constituents so far characterized by 5S rRNA analysis (bold lettering) mostly fall into the "purple photosynthe tic" group of the eubacteria [see inset (adapted from Stackebrand t and Woese, 1981) and text]. The sequences were aligned and the tree inferred as described by Stahl eta!. (1984) (also see text). The 5S rRNA sequences are from Erdmann eta!. (1984), Stahl eta!. (1984), Lane eta!. (1985), and N. R. Pace, D. A. Stahl, D. 1. Lane, and G. J. Olsen (unpublished data).

No 16S rRNA sequence information is yet available for Thermus, and because phylogenetic analysis based on 5S rRNA does not satisfactorily bridge longer phylogenetic distances (Section 6. 7), the suggested placement of Thermus with the purple photosynthetic bacteria should be considered tentative until the data base of reference sequences in this region of the phylogenetic "map" is more complete. , however, is clear. Members of the genus Thermus are formally described as filamentous, nonmotile, obligately aerobic, oligotrophic heterotrophs.

It has proven possible, using end-labeled primers rather than labeled dNTPs, to sequence directly from recombinant X DNA rather than subcloning into single-strand phage M13, the conventional approach (N. R. Pace, D. A. Stahl, D. J. Lane, and G. J. Olsen, unpublished observation). In the case of sorting among clones for unique representatives, sequencing reactions need be carried out with only one of the chain-terminating nucleotides, using only one of the primers. , ofT residues on sequencing gels) readily identify clones containing different 16S rRNA genes.
