IAI-Data-CRN_012_DIRZO_PLANTDIV: Variation in florisitc diversity in tropical and temperate ecosystems
Listed in NASA Earthdata CMR
This component of the CRN explores the variation in florisitc diversity in tropical and temperate ecosystems located on the northernost distribution of the Neotropics.
Description
Sampling protocol is based on a modification of the method originally proposed by Al Gentry to carry out standardized surveys of plant diversity at the scale of 0.1 ha. Data are available for a range of tropical sites ranging from dry forest to hyper-wet forests, as well as for mono-dominated to mixed temperate forests.
Our team has sampled a total of 35 independent sites (10 trandomly located transects of 50X2m per site) throughout Mexico (a total of 350 transects). All plants with diameter at breast height (DBH) of at least 1cm have been recorded and identification is nearly complete. All sites are georeferenced.

Soil samples were collected from each site too. For each sampling site, climatic data are available from in situ or near-by weather stations. Data are amenable for search of relationships between environmental variables (edaphic, climatic, geographic) and plant diversity (species, life forms).
Critical drivers of plant diversity can be explored with the data set. In addition, form all tropical sites, foliar material of the most common, and shared species across sites was also collected for ecophysiological analysis. Samples will be shipped to Drs.
Sala and Austin's lab for analysis.
