The Effect of Soil Texture on Richness and Diversity of Bacterial Communities (2011, background): “…been observed at a range of spatial scales, from sub-centimeter (Becker et al., 2006; Dechesne et al., 2003; Nunan et al., 2003; Grundmann and Debouzie, 2000) to meter (Bent et al., 2003; Nunan et al., 2002; Bundt et al., 2001) to kilometer or more (Fierer and Jackson, 2006; Cho and Tiedje, 2000).”
Pathways of mineral‐associated soil organic matter formation: Integrating the role of plant carbon source, chemistry, and point of entry (2018, background): “While there are regions of very low microbial biomass and activity, there are also microbial hotspots in the bulk mineral soil, including detritus (“the detritusphere”), biopores (such as earthworm burrows), and the surfaces of aggregates (Bundt et al., 2001; Kuzyakov & Blagodatskaya, 2015).”
Biogeographical patterns of soil molecular microbial biomass as influenced by soil characteristics and management (2011, positive): “At the same time, several studies demonstrated a highly positive relationship between the yield of DNA recovered and the measurement of carbon biomass in agricultural, grassland and forest soils, this latter being indicative of the size of microbial biomass (Marstorp et al., 2000; Bundt et al., 2001”
Rhizosphere: biophysics, biogeochemistry and ecological relevance (2009, background): “Bundt et al. (2001) also showed that preferential flow paths in soils were to be considered as biological hot spots, possibly because of being sites of deposition of organic matter and nutrients.”
Microbial Processes in the Vadose Zone (2005, background): “Nutrients (N and C, Table 2) decline dramaticallydirect counts, culturable counts (Palumbo et al., 1994; Severson et al., 1991; Veeh et al., 1996), SIR (Fritze with depth in both bulk soil and in the vicinity of preferential flow paths (Bundt et al., 2001); any increase inet al., 2000), extracted DN”
Microbial diversity and soil functions (2003, background): “However, microbial diversity of soil from preferential flow paths (cracks, fissures, biopores such as earthworm burrows or root channels) was similar to that of the bulk soil (Bundt et al., 2001), in spite of the fact that the former sample showed a greater concentration of organic C and organic N a”
Fungal communities are more sensitive indicators to non-extreme soil moisture variations than bacterial communities (2015, background): “…how the 272 dynamics of bacterial populations localized in different microenvironments are affected by 273 water fluctuation (i.e. different aggregate size or preferential flow paths; Bundt et al., 2001) is 274 necessary to determine whether a transient community is associated with drying periods.”
Archaea in dry soil environments (2009, background): “Some archaea became more rare and some more abundant with increasing soil depth showing adaptation to different depths and conditions in a study by Bundt et al. (2001).”
Extracellular DNA in soil and sediment: fate and ecological relevance (2009, background): “Cai et al. (2007) observed a higher protection of DNA against degradation by nucleases when it was adsorbed by clay organic matter rather than by inorganic clays.”
