Since development of the sustainable agriculture interest on soil conservation and maintenance
of the biodiversity ecosystem function has increased (González et al. 2003). Microarthropods,
mainly mites and springtails, represented about 98% of the soil fauna (Palacios-Vargas, 1983).
Nevertheless, there are few studies on those organisms living in coffee plantations, where there
are two or more convergent vegetational types, representing areas with biogeographical and
ecological importance, due the presence of tropical and temperate elements. That originate a
very high diversity and species richness in flora and fauna in that regions (Perfecto et al., 2003).
The aim of the present study was to compare the Oribatid mites and springtails communities
in three plots with different soil use, Coffee Plantation (CP), Acahual (A) and Cloud Mountain
Forest (CMF). They were sampling in ?El Nueve?, a coffee plantation located in the Sta. Ma.
Huatulco, Oaxaca State, Mexico. A total of 60 samples were taken, 20 in each plot, 10 of litter
and 10 from soil. The samples were processed in Berlese funnels. The fauna was stored in 70%
alcohol. After isolating and counting the specimens, slides in Hoyer?s solution were prepared in
order to identified the species. A total of 3,031 Oribatid mites belonging to 33 species were
collected, while a total of 1,177 specimens of springtails were collected, included in 43 species.
In the CP were found 27 species (14 for Oribatid mites and 13 of springtails), at A, the total of
species were 44 (19 Oribatids; 25 springtails), and at CMF, it was recorded the highest value of
species number, with 62 (32 for each group). We found differences in the soil and litter
communities, in soil were recorded 53 species (26 Oribatids; 27 springtails), while in litter were
found 57 species (25 Oribatids; 32 springtails). The most abundant Oribatid species were
Hoplophorella ca. fonseciai, Epilohmannia pallida, Tectocepheus sp., Karenella sp. and
Rostrozetes foveolatus; and the springtails Ceratophysella ca. gibbosa, Mesaphorura sp.,
Proisotoma ca. minuta and Pseudosinella ca. octopunctata.
For the Oribatid mites 18 species and 14 families represent new records for the State, and for
Collembola were 34 species and 5 families as new in Oaxaca. Soil pH, organic carbon content
and soil temperature influences the distribution and composition of springtails and mites
communities, in the different soil groups and uses.
This study was supported by the projects SEP-CONACyT 43702 and PAPIIT IN104807.
We acknowledgment to M.Sc. Leopoldo Cutz and Ricardo Iglesias their help in the identification
of Collembola and Oribatida species, respectively. Biól. Arturo García help in the data analysis.
