The objective of this work was to evaluate the species composition and functional groups of ants in nonagricultural (NA) and in irrigated areas (S, seasonal irrigation; P, irrigation with well water; W, irrigation with wastewater) in an arid agricultural region in central Mexico, throughout 2005 and 2006. A total of 52,358 ants belonging to 6 subfamilies, 21 genera and 39 species was collected using pitfall traps. The species best represented in all plots were: Forelius pruinosus, Pheidole obtusospinosa, Monomorium minimum and Dorymyrmex spp. NA plots recorded the highest density of ants. The highest values for diversity (H') and equitativity (J') were recorded in NA and P plots, while the lowest were recorded in W plots. Cluster analysis showed two different groups regarding species composition: NA-S and W-P. Functional groups recorded were: dominant Dolichoderinae, three species; subordinate Camponotini, five species; hot climate specialists, three species; tropical climate specialists, seven species; cold climate specialists, five species; cryptic species, one species; opportunists, six species; generalized Myrmicinae, nine species. Agricultural activity affects the structure of the ant community with epiedaphic forage, and the constant use of irrigation wastewater in conjunction with intense agricultural practices has negative effect upon species richness of epiedaphic ants. |

Abstract: A liquid chromatography-tandem mass spectrometry method was developed and validated for the simultaneous determination of the veterinary drug florfenicol (FF) and its major metabolite, florfenicol amine (FFA), in tilapia muscles (Oreochromis niloticus). Three different sample preparation procedures (DLLME, sub-zero, and modified QuEChERS) were tested. The best extraction results were obtained by using the modified QuEChERS. The quantification was made by using a LC-MS/MS analysis, with a Lichrocart Cartridge Purospher Star C8 HPLC column (250 mm×4.6 mm, 5 µm particle size). Analytes were separated with a mobile phase consisting of Milli-Q water to acetonitrile 40:60 (v/v), both with 0.1% formic acid. The validation parameters were recovery of 70 to 79% and 62 to 69%, limit of detection of 0.0625 µg g-1 and 0.125 µg g-1, and limit of quantification of 0.125 µg g-1 and 0.25 µg g-1, for FF and FFA, respectively. CC alfa was 1183 µg kg-1 and CC beta was 1365 µg kg-1 for FF, intraday and interday precision has CV greater than or equal to 20%, and linear range was 0.625 to 5.00 µg g-1. This method was shown to be simple and rapid when compared to other, more conventional methods. Also, it has low reagent and solvent consumption, with low waste generation, which is in line with the principles of green chemistry. The method was successfully applied for the analyzes of tilapia exposed to the antibiotic. |
