Traditional taxonomic
revisions and monographs,
like Flora Neotropica, are
static and hard to update
Biological monographs are
systematic and biological
treatments of all the species
of a given plant group and,
therefore, are often
substantial.
The same with printed Floras
Why Cyperaceae?
One of the 10 most diverse families of
angiosperms, with over 5400 species
Why Cyperaceae?
Total biomass worldwide is
enormous
A Chesapeake Bay (USA) salt marsh
can have over 27,660 Kg/ha of
Schoenoplectus americanus biomass!
The value of ecosystem
services in wetlands
dominated by Cyperaceae is
extremely high
Ecosystem services, including carbon
sequestration, mitigation of nitrogen runoff,
and erosion control in the Mississippi
Valley wetlands (USA) are valued at
US$ 1,500/ha annually
What do we know? What we know
– Floristic (Regional) Knowledge
– Taxonomic knowledge
What we do not know – Under-collected areas
– Groups not studied
Pooling the Data
• What to put online
• What do we have?
• What can you put
online that can’t be
published (e.g., multi-
entry keys, lots of
color photos)?
What we know about Brazilian Cyperaceae,
From a global perspective
What we know about Brazil is greatly improved by
adding data from adjacent countries
and from unfinished projects
Added to that is the knowledge of specialists in Brazil
and neighboring countries
In 2009, the first complete checklist of the
Cyperaceae of Brazil was published
Rodriguésia 60 (4). 2009
This work, with 9
authors, was the
foundation of the
Cyperaceae treated
in:
Made possible by the development of a multi-user, off-site data entry platform by
CRIA and JBRJ.
Based on all previous work done in and around Brazil, and on the available
databases at CRIA, JBRJ and NYBG.
The product of work during 2010 of 413 specialists who contributed a total of ca. 23
years of work.
Static vs. Dynamic web pages
Normal web pages must be modified and
updated individually
Many are ‘owned’ and maintained by
individuals who eventually will cease to
maintain them
Data stored as part of an institutional database,
however, can be displayed in web pages, but
is maintained institutionally
emonocot, KE EMu, and other databases
provide frameworks to display such data
