![]() Consequently, ecotourism should be regulated to minimize its effects in the site. Ecotourism in the park has caused a negative impact on the dung beetle assemblage structure due to the loss of habitat specialists in favor of widespread generalists. There were differences in composition, diversity, and evenness of the dung beetle assemblage, evidencing ecological disturbances in the intensive-use zone. We recorded a significantly lower beetle abundance in the intensive-use zone, even though biomass tended to increase with ecotourism intensity due to proportional increase in large-sized species. Six samplings using pitfall traps were carried out from June-November, 2013 in each zone. Three zones differing in tourism intensity: conservation, extensive, and intensive, were evaluated. The objective of this study was to evaluate the impact of ecological disturbances produced by ecotourism, using dung beetles as biological indicators in the park. To this respect, National Park El Imposible is the largest natural protected area in the nation, with 23% of its extension designated for ecotourism. Although ecotourism in El Salvador is currently underdeveloped, it has been proposed for the conservation of forests that remain within the territory. You are likely to trap beetles and other insects, as well as spiders and slugs. Dung beetle species with different sets of ecological traits may differ in their dispersal ability, so we suggest a new minimum distance of 100 m between pairs of traps to minimize interference between baited pitfall traps for sampling copronecrophagous Scarabaeinae dung beetles.Įcotourism involves visiting natural areas without adversely affecting biodiversity, an objective that is often not reached. Pitfall traps are extremely cheap to make and can be added to any garden. Pitfall and stocking traps were the most effective, followed by the pot trap. Our results suggest that, based on the analyses of the whole community or the species with the highest number of recaptured individuals, the minimum distance of 50 m between pairs of baited pitfall traps proposed roughly 10 years ago is inadequate. In this study, we found that the efficacy of baited trap designs varied substantially. Large-diurnal-tunneler species showed greater mobility than did both large-nocturnal tunneler and roller species. We found differences in mean movement rate between Scarabaeinae species, and between species with different sets of ecological traits. We investigated the mobility of dung beetles using mark-release-recapture technique, and tested the usefulness of the current recommendation for interaction distance between baited pitfall traps in the Brazilian Atlantic Forest. The baited kill traps (KB) are identical except that a bait bag hangs from a small fi sh hook beneath the centre. Understanding the dispersal process is of great interest in ecology because it is related to several mechanisms driving community structure. Cross-section of non-baited kill pitfall trap (KNB) design used during the study. If you can not cover the hole you can also lay bait, and create an edge that. This study provides an inventory of the arboreal and ground ant fauna contributing to the knowledge and conservation of Amazonian ant fauna.A primary goal of community ecologists is to understand the processes underlying the spatiotemporal patterns of species distribution. A simple design, but one that requires a lot of work, is the trapping pit. Also, the composition of the ant assemblages was different between these habitats (with only 20% occurring in both) indicating that complementary methods which include arboreal and terrestrial ants are indicated for efficient inventory. ![]() As expected, the abundance and richness of ants was higher on the ground than in the understory. Two hundred and three (203) species distributed among 23 genera and eight subfamilies were sampled, wherein 34 species had not yet been reported in the literature for Mato Grosso State. Moreover, we compared the composition of the ground dwelling and vegetation foraging ants. This paper aimed to list the ant species collected both on the ground and in the vegetation of the Parque Estadual do Cristalino, an important protected site in the center of the southern Amazon. However, the majority of inventories have concentrated on ground-dwelling ant fauna disregarding arboreal fauna. Ants are ecologically dominant and have been used as valuable bio-indicators of environmental change or disturbance being used in monitoring inventories. ![]()
