Description
This dataset presents the distribution of freshwater macroinvertebrates in Madeira Island streams.
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 713 records.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Geographic Coverage
Madeira is a typical oceanic island with unique biodiversity under increasing pressure. Madeira island is located 600 km off the Atlantic coast of North Africa, has an area of 742 km2 and a maximum altitude of 1861 m (Pico Ruivo). Madeira island comprises approximately 126 catchments and 200 streams ranging from 1st to 6th order.

Project Data
Here, we present the data obtained from the samples collected in a field campaign during the spring of 2015 which aims for a better understanding of the diversity and distribution patterns of freshwater macroinvertebrates in Madeira Island.

Sampling Methods
Benthic macroinvertebrates were collected following the national sampling protocol (INAG, 2008). Samples were fixed in 96 % ethanol and transported to the laboratory. In the laboratory, samples were rinsed through a sieve of 500 μm mesh size, and macroinvertebrates were sorted and preserved in 70 % ethanol.
| Study Extent | Freshwater macroinvertebrates from 40 sites (MAD01 – MAD40) from 27 permanent streams in Madeira island. |
|---|---|
| Quality Control | Macroinvertebrates were identified and counted under a stereo microscope (Zeiss Stemi, Deutschland). Identification was made to the lowest possible taxonomic level using identification keys (e.g. Tachet, Bournand & Richoux, 2002; Oscoz, Galicia & Miranda, 2011). |
