WebPelletier et al. ( 2012) studied the role of mound formation underneath vegetation, which, according to their field observations and model, leads to ponding in the bare interband areas during rare rainstorms, inhibiting plant survival. Their model included temporal evolution of (micro)topography. WebSoil macrofauna have both direct and indirect effects on litter decomposition and nutrient cycling, but their net effects are best considered within the context of the entire soil fauna community (Figure 3). As a class, detritivores are characterized by relatively low assimilation efficiencies; estimates vary but range from 10 to 30%.
