As indicators of environmental conditions, ants are very useful organisms. This study focused
on determining the composition and the functional groups of epiedaphic ants in non-agricultural
systems and agroecosystems with varying qualities of irrigation water, as well as seasonal
variations. This work is being carried out in Valley of Mezquital, a semi-arid ecosystem located
in Central Mexico, with a very important agricultural activity. Thirty nine plots with various irrigation
types were studied from 2005 to 2006 [nine non-agricultural plots (NA), nine temporal plots (T),
six plots irrigated with well water (P), and 15 plots irrigated with waste water (W)]. Twelve pitfall
traps were used in each plot. A total of 52,223 organisms were collected, belonging to six subfamilies
(Dolichoderinae, Ecitoninae, Formicinae, Myrmicinae, Ponerinae and
Pseudomyrmicinae), corresponding to 22 genera and 34 species. The highest abundances
were recorded in NA and T plots. The average of ants by trap varied from 65.3±d.e.9.39 in NA
plots, 36.31±6.77 in T, 9.49±1.36 in W, and 7.25±0.79 in P plots. The NA plots showed the
highest richness of species (30), followed by T (29), P (23), and W plots (24). The highest
similarity value among communities was recorded between the NA and T plots, with 91.5%
(similarity Sörensen index) and the lowest between NA and P, with 79.2%. The groups with
highest abundance and richness of species in all plots were Opportunists and Generalized
Myrmicinae (sensu Andersen, 1995) (with 6-8 spp). In particular, Hot Climate Specialists showed
more abundance and richness of species (5) in NA and T plots than in P and W plots. Generalized
Myrmicinae recorded the highest abundance in P and W plots, Opportunists in NA and Dominant
Dolichoderinae in T plots. Not irrigated plots (NA + T) are characterized by registering high
relative abundance of genera Liometopum, Forelius, Camponotus, Pogonomyrmex, Atta,
Dorymyrmex and Odontomachus, while irrigated plots (P+W) recorded a high relative abundance
of Tapinoma. It is possible to infer that the constant irrigation (with waste water or well water) has
a negative effect on the structure of the community of edaphic ants. Two communities are clearly
distinguishable: that of non-irrigated areas and the other of irrigated areas. In accordance with
the composition and abundance of species, areas may be characterized based on functional
groups, with emphasis on stress and disturbance. The functional groups characteristic of not
irrigated areas were Dominant Dolichoderinae (Liometopum and Forelius), Subordinate
Camponotini (Camponotus), Hot Climate Specialists (Pogonomyrmex), Tropical Climate
Specialists (Atta) and Opportunists (Dorymyrmex and Odontomachus); while the functional group
characteristic of irrigated areas was Opportunists (represented by Tapinoma). The decrease of
Dominant Dolichoderinae and Hot Climate Specialists, characteristic of conserved and natural
arid areas, respectively, as well as high abundance of Generalized Myrmicinae and Opportunists,
suggests that there are habitats with a certain degree of disturbance in the whole region. MenosAs indicators of environmental conditions, ants are very useful organisms. This study focused
