地理涵蓋範圍

Sampling stations are located in the high mountains of South of Ecuador nearby the city of Cuenca between -3.06963 and -2.64968 (WGS84) latitude and -79.00267 and -79.48180 (WGS84) longitude. Additionally, some algae samples were collected in the Amazon region between -0.0042333 and -2.610259 (WGS84) latitude and -75,23575 and -77.018503 (WGS84) longitude.

分類群涵蓋範圍

Macroinvertebrate: In the South of Ecuadorian region identification of macroinvertebrates is possible only till genus level. At the monitored sites 118 genus were identified. The following number of groups were identified only to family (47), order (1), subclass (2), class (2) and phylum (1)level.
Algae: The identification was carried out at several taxonomic levels. The following groups were identified: variedad (25), species (42), and genus (78).

取樣方法

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.

方法步驟描述:

1. 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.
2. 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.
