Abstract:
These data on temporal and spatial patterns of seedling recruitment in conjunction with data on flower and seed rain production allow tests of hypotheses concerning causes of inter-annual variation and roles of different mechanisms in facilitating species coexistence. The data are being used to, among other things 1) quantify seasonal and inter-annual variation in reproductive output in tropical plant populations and communities; 2) analyze relationships between reproduction and a variety of hypothesized local and regional climate drivers; 3) evaluate evidence for long-term directional trends which could reflect responses to anthropogenic global change; 4) quantify spatiotemporal variation in seed arrival and seedling recruitment of individual species; 5) analyze associated evidence of recruitment limitation, life history trade-offs, density dependent recruitment and regeneration niche partitioning; and 6) evaluate how these processes interact with inter-annual variation in climate and plant reproduction.

ADDITIONAL NOTES:
- Values of the variable SPECIES include the six-letter code “UNKSPP” for unknown species. Accompanying notes in the COMMENTS columns may indicate a partial identification to levels above species. Examples include, “VINE1” for unknown lianas, “MYRSPP” for the genus Myrcia, and “RUBIACEAE SP” for plants in the Rubiaceae family.
-
Records marked as ‘Q’ or ‘R’ for the variables ‘FINAL STATUS’ and ‘A/D/N/NF/Q/R’ are kept in the dataset for bookkeeping purposes and should not be used for any analyses.
-
Values for LEAVES, BARE SOIL, ROCK, HERBS, LIVE WOOD and DEAD WOOD for each 1 m2 in any given year XXXX are determined by considering the percent cover of each variable in a 3-dimensional volume between 0-10 cm above the ground.
-
Values for LEAVES, BARE SOIL, ROCK, HERBS, LIVE WOOD and DEAD WOOD in any given year are estimated to the nearest 5% and always sum to 100%.
-
The variable LEAVES includes large palm fronds and other fine organic matter (e.g., a mat of tiny rootlet threads).
-
The total percent cover of grasses and herbs per subplot is summed together with other herbaceous plants and listed in the HERB column.
-
The variable DEAD WOOD includes both standing dead stems and fallen woody debris.
-
The variable LIVE WOOD includes standing live saplings or trees, prone stems and woody vines that are rooted in and/or run through the plot.
-
Non-blank values for the variable HEIGHT GRASS are always associated with a value for the variable NUM. GRASS that is >0.
-
Non-blank values for the variable HEIGHT HELCAR are always associated with a value for the variable NUM. HELCAR that is >0.
