SystematicsScience of organismal diversityDiscovery, description and interpretation of biological diversityDiscovery and description of the evolutionary tree of life (phylogeny)Synthesis of information in the form of predictive classification systemsProduction of identification tools (e.g., keys, floras and faunas, monographs, databases, etc.)Slide3
What systematists do(when they are not doing phylogenetics)Field workSpecimens/herbariaDatabases, keysFloras, monographs, websitesSlide4
Field WorkSlide5
Important steps in doing field workFigure out where the plants grow (herbarium specimens, databases)Make contacts in those countriesSolicit appropriate collecting and export permitsFind the funds to do the field work!Get the proper equipment (either take it with you or get it when you arrive)Slide6
Important steps cont’d.Arrange for transportation (and lodging if visiting a field station)Collect the specimens (take any necessary measurements in the field; take photos)Process the specimens (drying, sorting into duplicates)Make and distribute the labels (including georeferencing)Arrange for shipping of your duplicates to your institutionSlide7
Collecting ChallengesSlide8
Bamboo flowers!
Costa Rica
Collecting bamboo leaf samples for DNA
(DNA usually requires a special permit)Slide9
PressingspecimensSlide10
Specimens are stored in the herbarium
A herbarium is a plant library,
containing pressed and dried
plant and fungal specimens.Slide11

A flora is a taxonomic treatment of plant diversity
in a given region or political unit or habitat.Slide26

A monograph is ataxonomic treatmentof a particular taxon,usually a family or genusor subdivision of one of
these.
