  • Belowground competition among invading detritivores 
    Chang, Chih-Han; Szlavecz, Katalin; Filley, Timothy; Buyer, Jeffrey S.; Bernard, Michael J.; Pitz, Scott L. (2016)
    The factors regulating soil animal communities are poorly understood. Current theory favors niche complementarity and facilitation over competition as the primary forms of non-trophic interspecific interaction in soil ...
  • Continuous <SUP>13</SUP>C and <SUP>15</SUP>N Labeling of Tree Litter Using a Climate-Controlled Chamber 
    Bernard, Michael J.; Pitz, Scott L.; Chang, Chih-Han; Szlavecz, Katalin (2015)
    Substrates with a unique stable isotope signature provide researchers with the ability to trace nutrients through food webs. Plant material labeled with carbon (13C) can be produced by exposure to carbon dioxide (CO2) with ...
  • Litter quality, dispersal and invasion drive earthworm community dynamics and forest soil development 
    Szlavecz, Katalin; Chang, Chih-Han; Bernard, Michael J.; Pitz, Scott L.; Xia, Lijun; Ma, Yini; McCormick, Melissa K.; Filley, Timothy; Yarwood, Stephanie A.; Yesilonis, Ian D.; Csuzdi, Csaba (2018)
    In temperate deciduous forests of eastern USA, most earthworm communities are dominated by invasive species. Their structure and functional group composition have critical impacts on ecological properties and processes. ...
  • Manipulating earthworm abundance using electroshocking in deciduous forests 
    Szlavecz, Katalin; Pitz, Scott L.; Bernard, Michael J.; Xia, Lijun; O'Neill, John P.; Chang, Chih-Han; McCormick, Melissa K.; Whigham, Dennis F. (2013)
    Summary Earthworms influence the biotic and abiotic characteristics of soils, including the diversity and abundance of bacteria and fungi, some of which form essential mycorrhizal connections with plants. The indirect ...
  • Methane fluxes from tree stems and soils along a habitat gradient 
    Pitz, Scott L.; Megonigal, J. Patrick; Chang, Chih-Han; Szlavecz, Katalin (2018)
    Forests are major sources of terrestrial CH4 and CO2 fluxes but not all surfaces within forests have been measured and accounted for. Stem respiration is a well-known source of CO2, but more recently tree stems have been ...
