Efecto del uso de suelo sobre la abundancia de artrópodos a nivel de orden y especies, en un agroecosistema al sur del Ecuador

Abstract

Abstract: In the Fina farm located south of Ecuador, the abundance of arthropods was studied, comparing order vs species, in three soil uses (low coffee plantation, forest, vegetable cropland) to know if they were affected. Hypotheses were posed as differences in the abundance of the two taxonomic levels and land uses, composition, and indicators 12.313 arthropods corresponding to 12 orders, and 853 dung beetles belonging to five species were collected. Vegetable cultivation was the one with the highest abundance in the two levels compared. The order that stands out for its greater abundance was Lepidoptera, and the species Dichotomius problematicus. In composition, groupings were found at the order level, and at the species level they share similarities between thethree uses. Indicator groups were identified only at the order level (Lepidoptera, Hemíptera, Hymenoptera and Odonatos) associated with the croplandof vegetables. The three uses do have an effect on the abundance of the two taxonomic levels studied. The indicator of biodiversity in this study had no influence, since similarity was found in the results of both levels.
