LifeStageCodeLifeStageNameLifeStageDescr
AAdultLife stage is an adult; wide use
AKAkineteThick-walled resting spore formed by transformation of a vegetative cell; primarily used for Algae taxonomy
CCystResting spore, usually thick-walled; primarily used for Algae taxonomy
GGametophyteSexual, gamete-producing stage; primarily used for Algae taxonomy
IMImmatureThe organism is immature and does not form structures needed for species identification; primarily used for Algae taxonomy
JJuvenileLife stage is a juvenile; wide use
LLarvaLife stage is a larva; primarily used for freshwater benthic macroinvertebrates (BMI)
NRNot RecordedLife stage was not recorded or is unknown
PPupaLife stage is a pupa; primarily used for freshwater benthic macroinvertebrates (BMI)
PMPalmellaPalmella-stage in the life history of flagellated algae where cells become non-motile and divide to form a mass of cells embedded in an amorphus mucilage; primarily used for Algae taxonomy
SSporophyteAsexual, spore-producing stage; primarily used for Algae taxonomy
SASubadultLife stage is a subadult; primarily used for freshwater benthic macroinvertebrates (BMI)
STSterileThe organism is in vegetative life-stage and does not form sexual reproductive structures needed for species identification; primarily used for Algae taxonomy
XUndefinedUsed when life stage is not defined (e.g., most non-insect taxa for bioassessments); primarily used for freshwater benthic macroinvertebrates (BMI)
ZOZoosporeFlagellated asexual spore capable of swimming and produced in a zoosporangium; primarily used for Algae taxonomy
ZYZygoteResting spore produced following the sexual union of gametes; primarily used for Algae taxonomy
