Description
The Aquatic Ecology Laboratory (Laboratorio de Ecología Acuática, LEA) of the University of Cuenca was formed in 2010 with the aim of generating knowledge on the biology and ecology of high mountain freshwater ecosystems (lotic and lentic). LEA carries out research projects within several research lines such as: freshwater biomonitoring, estimation of environmental flows, taxonomy of freshwater insects, algae, ecology of aquatic communities, use of remote sensing for water resource management, lake limnology, etc. The biological data obtained from both lakes and rivers are consolidated in the database. The dataset published contains: 747 records derived from monitoring of lakes and rivers in the Ecuador.

Sampling Methods
Macroinvertebrates: Different methodologies were applied based on the purpose of the study and the sampled ecosystem. In the rivers, quantitative samples were taken using Surber sampler where the sediment was stirred during 30 seconds on the defined area of the net. In the high mountain lakes, in all possible littoral habitats was swept by hand net during 3 minutes period.
Algae: In each lake, a total of 30 liters of water were collected from integrated samples (at three different points) in plastic containers taken from a depth of 0.5 meters; (i) samples were collected at two points at the littoral areas (10 liters each) and (ii) one point in the center of the lake. In the rivers, integrated samples were taken from each river bank (10-10L) and one from the center (10L) of the main channel until completing 30 L. Once the samples were obtained, they were filtered with the use of a plankton net (mesh: 20 microns), which resulted qualitative samples of algae.
| Study Extent | Macroinvertebrates were collected for different research purposes in Andean lakes and rivers.
Algae were collected in the research project "Biodiversidad de organismos de agua dulce del Ecuador" in lakes and rivers. |
|---|---|
| Quality Control | Macroinvertebrate: Field protocols were elaborated and applied on the field and in the laboratory for sampling and identification of macroinvertebrates for each research project.
Algae: Rigorous field controls were carried out to ensure the quality of the collected samples. In addition, laboratory controls were carried out to verify the correct taxonomic identification of the specimens and the precision of the measurements made. |
Method step description:
- Macroinvertebrate: Samples were taken on the field and conserved in 95 ethanol or 4% formaldehyde. In the laboratory, the samples were washed carefully and identification of all individuals were carried out using specific taxonomic keys.
- Algae: Water samples were collected in the field and preserved using 4% formaldehyde. In the laboratory, samples were filtered and concentrated before taxonomic identification of the algae was performed. This was carried out by observing specimens under an Olympus CKX41 inverted microscope and taking digital photographs for later analysis. Taxonomic identification was carried out by using specific keys and by comparisons with specialized literature. Finally, the samples were deposited in the Aquatic Ecology Laboratory of the University of Cuenca, Ecuador, for future reference.
