|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...
