Abstract: In this review, we compiled published results
on biological interactions at different spatial scales in the Monte
desert of Argentina and identified gaps in current knowledge. We
presented evidence of competitive and facilitative plant–plant
conspecific and heterospecific interactions, and plant–soil–microbes
interactions in relation to the abiotic environment at the fine
patch-scale. We also showed evidence of animal–animal interactions
and plant–animal interactions at the community scale through
study cases involving both native and introduced herbivores. Moreover,
we identified bottom-up and top-down forces governing the interactions
between granivores (birds, ants, and small mammals) and seed availability/production
at the community scale. At the landscape scale, we discussed feedbacks
between domestic grazers and the spatial patterns of resources and
their interrelationships with processes occurring at other scales.
We concluded that research has steadily increased during the last
6 years but knowledge on biological interactions in the Monte desert
is still scarce, particularly at a landscape scale.
