Field Work, Herbaria, Databases, Floras,

and Monographs for Plant Systematics

Spring 2013


Systematics

Systematics

  • Science of organismal diversity

  • Discovery, description and interpretation of biological diversity

  • Discovery and description of the evolutionary tree of life (phylogeny)

  • Synthesis of information in the form of predictive classification systems

  • Production of identification tools (e.g., keys, floras and faunas, monographs, databases, etc.)


What systematists do when they are not doing phylogenetics

What systematists do(when they are not doingphylogenetics)

  • Field work

  • Specimens/herbaria

  • Databases, keys

  • Floras, monographs, websites

Field Work


Important steps in doing field work

Important steps in doing field work

  • Figure out where the plants grow (herbarium specimens, databases)

  • Make contacts in those countries

  • Solicit appropriate collecting and export permits

  • Find the funds to do the field work!

  • Get the proper equipment (either take it with you or get it when you arrive)


Important steps cont d

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 institution

Collecting Challenges


Field work herbaria databases floras and monographs for plant systematics

Costa Rica

Collecting bamboo leaf samples for DNA

(DNA usually requires a special permit)

Bamboo flowers!

Pressing

specimens


Field work herbaria databases floras and monographs for plant systematics

Specimens are stored in the herbarium

A herbarium is a plant library,

containing pressed and dried

plant and fungal specimens.

described in 2006

We still don’t know our own flora completely!

A flora is a taxonomic treatment of plant diversity

in a given region or political unit or habitat.
