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.

PROJECT TITLE: Frog Population Dynamics
PROJECT DESCRIPTION: El Verde Station, located in the tabonuco forest zone on the NW side of the Luquillo Experimental Forest (LEF), has hosted numerous scientific efforts since the 1960s. Thus, a great deal of information exists concerning anuran populations at the site over the past 30 years. Although past surveys did not use consistent techniques, they clearly document the general status of the anuran community of the area. I began working at El Verde in the 1970s and have collected data on the anuran community primarily in the 1980s and 1990s. Until recently, these surveys also lacked a consistent sampling protocol, although they clearly document declines in species richness in comparison to earlier records.
Most Puerto Rican Eleutherodactylus are terrestrial frogs that breed for prolonged periods of time in more or less continuous habitat. Because their life cycle lacks a free living larvae stage, reproductive behavior is not tied to bodies of water and they do not have the large aggregations typical of many aquatic breeders. For these reasons, assessing their population status requires examining fairly large areas of habitat. I began systematically sampling the anuran community on a 12 ha grid at the Bisley watersheds in 1989 and a second 16 ha grid at El Verde in 1993. These efforts have provided a comprehensive data set that can be used to evaluate future changes in the anuran community in this forest.

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: Population estimates and body sizes of E. coqui were collected on fertilization, litter removal, and control plots.
DATA SET METHODS: Mark-recapture. Adult coquies (725 mm SVL) were and measured with dial calipers. Each was toedipped, individually in some plots, by cohorts or others. Sex and reproductive condition were noted. Juveniles were counted.

DEFINITION OF VARIABLE |
A number assigned by the LUQ infromation manager to facilitate data quality control and hte change of data file structure.. All records have a value in this field. | MRCE fertilization plot plot identifier using the same nopnmenclature as the original MRCE proyect. Each contain the corresponding MRCE Proyect's data variable -Block-; a Roman number representing a 20x20 m square with 10x10 m inner measurement plots. | Type of block treatment. The three treatments are , and | Sex of captured frog, It is left blank if the sex could not be determined. | This
codes the reproductive status, pattern morph, and toc-clip of each animal
marked. The codification is as follows: A1 2345 b where
A represents the reproductive status: male - female;
1 represents a pattern morph (
9- wild type mottled;
11-vertebral stripe;
16-dorsalatesal stripes;
5-spots;
6-interocular bar;
1-smooth monocolor;
2-5=toe numbers); the 4 digit represent the 4 feet (2-left hand; 3-right;
4-left foot;
5-each ranges from 1-4 where its left most toe and 4 is right most);
b means thumbs; Blank-is an optional and determined series representing no thumbs clipperd; T- is an optional and determined series meaning a tumb was found clipped on left foot O-is an optional and determined series meaning a thumb was found clipped on right foot. |
