LUQ LTER DATA SETS DOCUMENTATION FORM

ON-LINE VERSION

A DATA SET is a series of observations collected by the same methodology. Each data set should have documentation sufficient for someone unfamiliar with the research to replicate the study. Data sets may be broken into subsets (data files) that are discrete in space and time, in that order. The documentation for a data set should include all spatial and temporal subdivisions of the data.

We define a data file as a component of a data set. A data set can have only one data file or more. Basically, different data files have different data structures or format.

DATA SET ABSTRACT: Seasonal rhythms of flowering and fruiting are an important component of the community dynmics of tropical forest and can be a critical determinant of the dynamics of consumer populations. We sampled the weekly production of flowers and fruits between July 1, 1992 and June 29, 1994 at two sites in the Luquillo Experimental Forest. At El Verde Field Station we placed baskets (numbered 1-120) along trails in the Luquillo Forest Dynamics Plot and in the Bisley Experimental Watersheds (baskets numbered 121-180) at the sites used to measure litterfall. Each reproductive part was counted and identified to species (in the data set using a six letter code -- see species list for full species names) and type (identified using a number code 1 - 6; see Table 1).

Data collection was terminated at Bisley at the end of the period, but sampling continues, on a biweekly basis, at El Verde.

DATA SET METHODS: These data are being used to (1) determine the seasonality of flowering and fruiting in tabonuco forest and test hypotheses concerning the causation of seasonality (or lack thereof), (2) test the effect of annual variation in rainfall and other climatic variables on seed and fruit production of individual species, and (3) compare the relative dispersability of species on the Luquillo Forest Dynamics Plot by applying information on the spatial distribution of canopy trees to the data on seed and fruit fall. Data collected in this study will will be compared to data collected by F.N. Scatena and colleagues using the focal species method at the same sites during the same time period. These data also serve as background information on the flowering and fruiting of individual species.
