| Popis: | This work started in the spring in 1996 and finished in the winter in 1997 and it had as its objective to study the populational survey of soil fauna in the Pinus elliotti and Eucalyptus spp. in areas situaded in Campus at Federal University of Santa Maria, Rio Grande do Sul, Brazil. An extractor was utilized to collect the soil from 10 sample points, in the 0-5, 5-10, 10-15 and 15-20 cm of soil depth, in each season of the year. With this study it was possible to identify some representants of Phylum Annelida and Arthropoda who belong to fauna-soil-vegetable context. The individual total, its percentile and number of individual for square meter were obtained. It was observed the predominance of Phylum Arthropoda and, in special, of Insecta class in the Eucalyptus spp. area; and the Phylum Annelida in the Pinus elliottii area. The depth variable originated mathematical models to explain the populational distribution for each studied areas. The seasons of year variable did not show a significative difference. It was not possible to establish a populational distribution model. |
