Organic mutualim also influences water and nutrient status of soils, thus the availability of these physical resources 12 is affected by the organisms that once inhabited that landscape.

Background: Soil and aerial seed banks directly affect recruitment in plant populations. Soil banks result as the balance between seed inputs and outputs. Seed bank dynamics vary by species and environmental conditions. Few records on cacti seed banks are available. Questions: What type s of seed bank s do two cacti genera form in a lava-field reserve?

Does seasonality influence the seed bank dynamics? Are inputs and outputs associated to the microenvironment? Studied species: Opuntia tomentosaO. Methods: We collected soil samples from four microenvironments during the rainy and the dry season ssearched for seeds and tested their viability. We compared the number of inputs, outputs and viable seed by microenvironment and season. For M. Results: Opuntia seed bank inputs occurred in all microenvironments and in both seasons.

Rain favored inputs in hollows by secondary seed dispersal. We registered a large number of outputs caused by germination, granivory and loss of viability. Opuntia seed bank was developed in headland, plain and slope. No Mammillaria seed inputs were found, neither an aerial bank in M. Mammillaria seed dynamics may hinders recruitment for their populations. Baker HG.
