RESUMO
Soil mite diversity (Prostigmata, Mesostigmata, Astigmata) inhabiting in litter-soil layer from a Shrubland and a Deciduous Forest was estimated from December 2000 to November 2001 in the University Park of UCLA (Universidad Centroccidental Lisandro Alvarado), state of Lara, Venezuela. Samplings were made by using pitfall traps along an 1,800 m-transect in both areas. All morfotypes were mounted in microscope slides using Hoyer's medium. A total of 51 mite morfotypes were collected with higher abundance in Prostigmata (2,528) as compared to Mesostigmata (926) and Astigmata (12). Eupodidae (Prostigmata) and Macrochelidae (Mesotigmata) showed higher abundance in both locations. Higher morfotype richness (S= 43), diversity (H'= 2.67) and evenness (E= 0.69) were found in Deciduous Forest compared to values from Shrubland (S= 36, H'= 2.12 and E= 0.52). Both areas showed a similarity index (J') of 0.59. Although more individuals were found in Shrubland, the diversity-dominance curves indicated that this is a more disturbed habitat than Deciduous Forest. Further detailed studies are required to determine acarofauna role in trophic web maintenance in soils from tropical areas.
