Efectos del Cambio Ambiental en las comunidades de organismos de los r?os mediterr?neos

Collection of aquatic macroinvertebrates of the studies of biodiversity monitoring and the
ecological state of the rivers and streams. The study sites are within the
protected areas of the Natural Parks of the Diputaci? de Barcelona and in other
river reaches with reference conditions of the province of Barcelona. The main
objective of the project is to examine whether global environmental changes are
affecting the structure of these ecosystems. The collection includes specimens
collected in spring and summer from 2012 to 2019. Specimens of
macroinvertebrates are sorted and identified at major groups (6%), family
(19%), subfamily (9,5%), tribe (2.5%), genus (51%) and species (11,5%) level.
The macroinvertebrates have been fixed in 4% formaldehyde or 70% ethanol and
preserved in 70% ethanol in 5mL vials. This project is the continuation of the
first river quality monitoring studies that started back in 1979, which data
will soon be included in GBIF as well. On the other hand, as the project has
continuity in the future, this collection will grow year by year.
