Hydrograph at Río Tempisquito
Stream Research and Data
Estación Maritza is located near the banks of the Río Tempisquito, and within easy walking distance of 5 other permanent streams that are all tributaries of the Río Tempisque. These streams have been the focus of many of our studies of stream ecology and biogeochemistry. Our efforts have also extended to permanent and temporary streams near other research facilities such as Santa Rosa, Cacao, San Cristóbal, and Pitilla.
We are happy to share data collected for this project and to collaborate in its interpretation. Requests for data access and proposals for collaboration should be directed to John Jackson.
To help continue our work, and in the process facilitate the studies of other researchers needing access to these data, please acknowledge our financial supporters with the following statement:
“Funding support for the ________ data from Área de Conservación Guanacaste came from the National Science Foundation Grant DEB 05-16516, and the research endowments of the Stroud Water Research Center.”

Thraulodes mayfly larva
Data for streams of the ACG include physical, chemical, and biological variables.
Some variables such as air and water temperature, rainfall, stream discharge, organic matter inputs and exports, and adult aquatic insect emergence have been collected more or less continuously or regularly since 1990.
Data for other variables such as analyses for specific chemicals or various aspects of the structure and function of stream biota have been collected far less frequently.
| Data collected regularly since 1990 | |
|---|---|
| Air temperature | Seston |
| Rainfall | Litter and leaf |
| Stream discharge/stage height | Adult aquatic insect collections |
| Water temperature | |
| Data collected at various times and frequencies | |
|---|---|
| Inorganic nutrients | Carbohydrate molecules |
| Base cations | Amino acid molecules |
| Anions | Tetramethyl ammonium hydroxide GC/MS profiles |
| pH | Pesticides |
| Alkalinity | Bacterial densities |
| Conductivity | Bacterial species (TRFLP profiles) |
| Dissolved organic carbon | Diatom species list and densities |
| Biodegradable DOC | Larval aquatic insect collections |
