      abstract     = {The impact of termites on nutrient cycling and tropical
                      soil formation depends on their feeding habits and related
                      material transformation. The identification of food sources,
                      however, is difficult, because they are variable and changed
                      by termite activity and nest construction. Here, we related
                      the sources and alteration of organic matter in nests from
                      seven different termite genera and feeding habits in the
                      Terra Firme rainforests to the properties of potential food
                      sources soil, wood, and microepiphytes. Chemical analyses
                      comprised isotopic composition of C and N, cellulosic (CPS),
                      non-cellulosic (NCPS), and N-containing saccharides, and
                      molecular composition screening using pyrolysis-field
                      ionization mass spectrometry (Py-FIMS). The isotopic
                      analysis revealed higher soil δ13C (-27.4‰) and δ15N
                      (6.6‰) values in nests of wood feeding Nasutitermes and
                      Cornitermes than in wood samples (δ13C = -29.1‰, δ15N =
                      3.4‰), reflecting stable-isotope enrichment with organic
                      matter alterations during or after nest construction. This
                      result was confirmed by elevated NCPS:CPS ratios, indicating
                      a preferential cellulose decomposition in the nests. High
                      portions of muramic acid (MurAc) pointed to the
                      participation of bacteria in the transformation processes.
                      Non-metric multidimensional scaling (NMDS) revealed
                      increasing geophagy in the sequence Termes < Embiratermes <
                      Anoplotermes and increasing xylophagy for Cornitermes <
                      Nasutitermes, and that the nest material of Constrictotermes
                      was similar to the microepiphytes sample, confirming the
                      report that Constrictotermes belongs to the
                      microepiphyte-feeders. We therewith document that nest
                      chemistry of rainforest termites shows variations and
                      evidence of modification by microbial processes, but
                      nevertheless it primarily reflects the trophic niches of the
                      constructors.},
