April, 13th, 2008 - New trait online

After extensive error checks, new traits are now online. To avoid additional sources of errors, the aggregation routines are not activated for most of these traits. You will only receive the raw data (one record per species, trait and single study).


July, 14th, 2006 - Help file extended

The help file available from the help link on the top banner of the leda web pages now contains valuable information on how to constrain queries to a list of species that you can upload


July, 14th, 2006 - Bug correction

There was a bug within the set default attributes functionality leaving the webquery application in a non-usable state whenever the default button was clicked on. The button may be used now, but the default attributes per trait still have to be reviewed. Comments are welcome. The mentioned bug could only be discovered because we had valuable feedback from webquery users. Please continue to contact us via email (support_at_leda-traitbase.org, replace '_at_' by '@') whenever you suspect a bug. Thank you!


July, 10th, 2006 - Complete publication list available

The list of papers has been completed.


July, 10th, 2006 - Bug correction

There was a bug blocking the LEDA webquery. It has been corrected. Users now get notified when their webquery session expires due to prolongued inactivity


July, 1st, 2006 - The first public version of the Traitbase is on line

In version 0.1 the LEDA Traitbase offers trait data for

shoot growth form, leaf distribution along the stem, woodiness, branching, canopy height
age of first flowering, plant life span, specific leaf area, leaf dry matter content, leaf size
seasonality of buds, bud number / vertical distribution
seed number, seed shedding, seed crop frequency
seed releasing height, terminal velocity

Data quality control for other traits is still under way, namely for
buoyancy, endozoochory, epizoochory, diaspore type, dispersal vector
persistence of connections between mother and daugther plants
number of offspring shoots, lateral spread, clonal growth organs
seed bank longevity, seed mass, seed shape
morphology of dispersal unit, plant growth form, habitat characteristics
. Data for these traits will be published once data quality control is finished. This will hopefully happen before October 2006.

While we have done our best to avoid errors, we can not guarantee error free data and software.
Should you discover errors in the data, please contact us at editor_at_leda-traitbase.org.
Should you discover errors in the software, please contact us at support_at_leda-traitbase.org.
(Replace _at_ by @ in the e-mail addresses above. We had to rewrite them to avoid phishing attacks)
