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.

DATA SET IDENTIFIER : Heliconia fluid and organic matter analyses

PROJECT TITLE : Invertebrate diversity in Heliconia flower bracts at El Verde (Heliconia flower bracts invertebrate diversity in the LEF)

PROJECT DESCRIPTION : This study complemented the work on bromeliad microcosms. It was carried out to compare the abundance and diversity of the invertebrate fauna supported by the accumulated fluid and organic matter in Heliconia bracts with that of the aquatic component of the bromeliad microcosm.

DATA SET ABSTRACT: Mineral concentrations measured in Heliconia bract fluid and organic matter accumulated in the bracts.

DATA SET METHODS:  Heliconia inflorescences were collected from the same areas as the plants which provided the data for invertebrate abundance. Bract fluid and retained organic matter from each individual bract was collected. Material was pooled [to obtain sufficient quantities for analysis] from upper [with flowers still unopened], middle [flowers ready for pollination] and lower [most floweres in a state of decay] bracts.
