Cambios en la comunidad macrofaunística en suelos del Vichada (Quartzipsammentic haplustox) afectados por las quemas

The changes occurred in soil macrofaunistic community of experimental plots in the region of Marandua (Vichada, Colombia), when the soil way subjected to the action of fire, were studied. In general, there is an increase of taxonomic groups (39%, because of the burning. The Classes Insecta, Arachnida, and Oligochaeta were found during the 16months of experimental work under three treatments (no burning, burning and double burning). The largest increase of Orders was registered in the Class Insecta in each treatment. The total number of individuals decreased (55%, as result of the first burning... Mehr ...

The changes occurred in soil macrofaunistic community of experimental plots in the region of Marandua (Vichada, Colombia), when the soil way subjected to the action of fire, were studied. In general, there is an increase of taxonomic groups (39%, because of the burning. The Classes Insecta, Arachnida, and Oligochaeta were found during the 16months of experimental work under three treatments (no burning, burning and double burning). The largest increase of Orders was registered in the Class Insecta in each treatment. The total number of individuals decreased (55%, as result of the first burning but, these valúes, presented an increase in number and variety during the following ten months. ; Se estudiaron, en parcelas experimentales de la región de Marandúa (Víchada, Colombia), los cambios que sufre la comunidad edafofaunistica cuando el suelo es sometido a la acción del fuego. Los grupos taxonómicos, en términos generales, aumentan (39% a causa de la quema; las clases Insecta, Arachnida y Oligochaeta se registraron durante los 16meses de experimentación y bajo los 3 tratamientos aplicados (no quema, quema y quema recurrente); la clase Insecta presentó el mayor incremento de órdenes con cada una de las quemas. El número de individuos disminuyó en un 55% como consecuencia de la primera quema, pero se recuperó e incrementó variedad, durante los 10 meses siguientes a ésta.
