Concepts
9 concepts
nonconsumptive effects
Behavioral, physiological, and life-history changes that reduce the risk of predation but have associated energetic or fitness costs to prey individuals and populations
nitrification
The oxidation of ammonia to nitrate via nitrite, linking nitrogenous organic matter remineralization to nitrogen loss processes in the microbial N-cycle
invasive species establishment
The process by which non-native species become established and spread in new environments
invertebrate drift
Downstream movement of benthic invertebrates in flowing water either naturally or induced by disturbance
stalk production
Production of extracellular polymeric stalk material by diatoms when photosynthetic rates exceed cellular growth rates
drift phase
biofilm succession
The sequential development of microbial communities on substrates following disturbance
hydro-geomorphological constraints
Physical habitat constraints related to water flow and stream geomorphology that affect oviposition site availability
