PROJECT TITLE: Bromeliad invertebrate diversity in the LEF

PROJECT DESCRIPTION: Tank bromeliads form complex, but discrete, microcosms whose biological, physical and chemical parameters can be sampled in their entirety. Plants impound canopy litter and throughfall water, and form a microhabitat for mainly detritivorous animal communities. This study of their fauna provided a natural way to examine diversity, and also the relationship between diversity and habitat parameters at different elevations in the LEF.

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 FILES (SUBSETS):

Data File No.	Data File Identifier	On-Line Filename	Starting Date	Periodicity of sample	End Period
1	Bromeliad chemistry	Bromeliadchemistry.txt	February 1996	once	February 1996

RESEARCH LOCATIONS: Three areas within the LEF: Tabonuco at El Verde, Palo Colorado at Tradewinds Trail, and Dwarf Forest at Pico del Este.
