|Detritivore Diversity or Dominant Species: What Drives Detrital Processing?
||The role that biodiversity plays in maintaining ecosystem functioning has been debated for nearly two decades. Previous research suggested that a dominant species (Pycnopsyche gentilis) and not detritivore diversity determined leaf breakdown in a so...
|Effects of a Low Head Dam on a Dominant Detritivore and Detrital Processing in a Headwater Stream
||I evaluated the breakdown of yellow birch leaves in the presence and absence of P. gentilis using a leaf pack breakdown experiment. Leaf packs were placed in reaches above the dam where P. gentilis is present and below where it is essentially absent....
|Partner Control and Environmental Fouling in the Crayfish-Branchiobdellid Symbiosis
||Previous research found that crayfish (Cambarus chasmodactylus) may be engaged in a cleaning mutualism with ectosymbiotic worms (Annelida: Branchiobdellidae), yet mechanisms for symbiosis establishment and maintenance remain unknown. In addition, it ...
|Ontogenetic Shifts and Symbiont Succession in a Freshwater Cleaning Symbiosis Mutualism
||Host-symbiont associations and the outcome of symbioses may vary over host ontogeny. I examined how changes in crayfish size can influence their associations with ectosymbiotic branchiobdellidan worms and the consequences of these associations for bo...
|Do Inhibitory Interactions Between Detritivores Influence Leaf Breakdown?
||Recent research suggests that inhibitory interactions among detritivore taxa may influence the effect of either taxa on detrital processing. Larvae of the stonefly Tallaperla maria were found to inhibit leaf consumption by larvae of the cranefly Tipu...
