Doñana’s Singular Scientific-Technical Infrastructure (ICTS-RBD) provides access and support to carry out research at the Doñana Protected Areas.

For such purpose, it provides researchers with accomodation, various facilities and technical/logistical support. It also runs monitoring programs to assess the status and trends of biodiversity, provides online access to all the information gathered by these monitoring programs and delivers ICT service management and tools to facilitate the search and use of that information.


The Lepidoptera Cyaniris semiargus flies in May in Doñana

Cyaniris semiargus and its food plant Armeria velutinaenia  at Doñana

Cyaniris semiargus is a small lepidopteran from the Lycaenidae family that reaches in Doñana its southernmost distribution limit. At this latitude, besides Doñana, it its only observed at higher altitudes in the Sierra Nevada mountains. The Doñana population can be considered a rarity, associated to wet microhabitats linked to subsuperficial groundwater levels. These conditions allow for population persistence despite the high temperatures and scarce rainfall.

In spring, adults emerge in the dry shrubland (monte blanco) where the food plants, Armeria velutina, grows (see picture by Isidro Román). In May 2021, members of Doñana’s Biodiversity Monitoring Group (ICTS-RBD) observed adults flying during the butterfly surveys performed between March and October. These surveys form part of Doñana’s long-term Monitoring Program and are integrated in the National Butterfly Network (BMS-Spain) and the European Butterfly Monitoring (eBMs).

Cyaniris semiargus presents sexual dimorphism (different coloration in males and females), which allows for sex identification as they fly.  The upper (dorsal) side of the wings is purple in males and brownish in females.  Both can be differentiated from other lycaenid species by the lack of moon-like orange marks in the lower rim (submarginal part) of the posterior wings.  


Start a project

If you plan to do research in Doñana, you must bear in mind that your project must be approved by the Research Access Commission of the Doñana Participation Council. The ICTS-RBD provides assistance throughout the procedure. Read more

Request access, accommodation and/or technical and logistic support

Once your research project has been approved by ICTS-RBD, you can request access and accomodation in the Biological Reserve using this online form and/or logistic or technical support using this online form . Do not forget to read carefully the facilities’ use rules. Read more

Request biodiversity data

You can visualize ICTS-RBD’s biodiversity monitoring data at the Data Infrastructure and consult essential ecosystem indicators derived from them at the Global Change Observatory. Raw data are offered free of charge to competitive research projects, subject to the following terms and conditions of use included in this data-request form.
