Community structure and diversity of sigmodontine rodents (Muridae: Sigmodontinae) inhabiting maize and soybean fields in pampean agroecosystems, Argentina

Mostrar todas las versiones(2)

The aim of this work was to characterize and compare the communities of small sigmodontine rodents present in soybean and maize plots according to specific composition, richness, diversity and equitativity. The study was performed over two consecutive years (periods); a follow up was made in crop pl...

The study was performed over two consecutive years (periods); a follow up was made in crop plots from sowing (early crop stage) to post-harvest (stubble). For both crop types, analysis was conducted considering the entire plot and each of its habitats (field and border). The results indicate that although rodent communities were composed in both types of plots of the same species: Akodon azarae, Calomys laucha, Calomys musculinus and Oligoryzomys flavescens, these were absent in some sampling months. A. azarae and C. laucha were the most abundant species, the former being captured in the borders and the latter in the fields, regardless the type of crop. Diversity was higher in maize than soybean plots when crops were mature, or after harvest. Differences in diversity were due to both changes in richness (generally by absence of C. musculinus or O. flavescens) and changes in equitativity (due to a high similarity between the densities of C. laucha and A. azarae). Species diversity varied according to the developmental stage of the crop cycle and differences resulted from changes in species richness (generally by absence of C. musculinus or O. flavescens) and equitativity (by high similarity in the densities of C. laucha and A. azarae).
