These gradients affect community structures, generating beta diversity replacement patterns. The two main patterns of spatial replacement are turnover and nestedness. However, there are very few studies that analyze diversity changes along environmental gradients in the Colombian Caribbean region. In an attempt to understand these spatial changes, a complete sampling was conducted in five Colombian Caribbean ecoregions (Golfo de Morrosquillo, Montes de Maria, Sabanas, San Jorge, and La Mojana) using dung beetles as an indicator. In each region, a linear transect with 20 pitfall traps baited with dung was established. Differences in abundance, richness, Shannon-index, evenness, and beta diversity between ecoregions were evaluated. A total of 923 individuals belonging to 27 species were collected. The tribe Deltochilini and the genus Canthon were the most diverse. The most abundant species was Silvicanthon aequinoctialis. Significant differences were found in the parameters measured between the ecoregions. A Beta diversity index established a clear spatial pattern demonstrating high turnover with low nestedness values. The Montes de Maria ecoregion has the highest diversity, which was linked with the maintenance of conserved forest fragments. It is advisable to generate conservation strategies and the designation of a new National Natural Park for Montes de Maria in order to stop the negative impact caused by agricultural and cattle farming expansion in the region.

This work was carried out in the province of Rodríguez de Mendoza, Amazonas region, Peru, with the objective of analyzing the effect of artisanal traps of different colors and attractive alcoholics in the capture of adults of coffee borer adults, Hypothenemus hampei, in a highly infested plantation, and its implication in reducing the incidence of damage caused by this pest. Six treatments generated from the combination of levels of the following color factors (transparent, red and green) and alcoholic attractants (without and with coffee essence) were evaluated. The test was conducted in a randomized complete block experiment design. The incidence of coffee berry bore damage was measured in periodic measurements every 30 days, while the capture levels (adults / trap) were evaluated every 15 days. The obtained data was subjected to an analysis of covariance, detecting statistically significant differences between the treatments and once applied the multiple comparisons test, specifically minimum significant difference, it was evidenced that the red trap without essence of coffee captured a greater number of adults (with a maximum of 4,000 adults / trap / week) and proved to be more effective in reducing the incidence (43.7 % less than the initial incidence). On the other hand, the least effective trap was the transparent one without coffee essence.","PeriodicalId":54476,"journal":{"name":"Revista Colombiana de Entomologia","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2020-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48644923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
