- Abstract
- The data present here come from samples collected during several monitoring programs developed between 1996 and 2018 which aimed to characterize the biodiversity of inland aquatic ecosystems (lakes and streams) from the islands of Santa Maria, São Miguel, Terceira, Pico, São Jorge, Faial, Flores and Corvo (Azores, Portugal) and to assess the ecological status of these waterbodies using biological quality elements together with physico-chemical and hydromorphological quality elements. These programs contributed to improving the knowledge of cyanobacteria distribution in the Azores, the phytoplankton community structure in regional freshwater ecosystems and the main environmental drivers of aquatic communities in these ecosystems.
- Funding
- This research was funded by Secretaria Regional do Ambiente – Governo dos Açores (Contrato Nº 8/2003/DROTRH), Secretaria Regional do Ambiente e do Mar – Governo dos Açores (Ajuste Direto Nº 18/2009; Concurso Público Nº 3/2009; Contrato Nº 3/2011), Secretaria Regional dos Recursos Naturais – Governo dos Açores (Concurso Público 1/DRA/2014), Fundo Regional para a Ciência e Tecnologia – Governo dos Açores (M3.1.a/F/017/2015) and by FEDER funds through the Interreg-MAC 2014-2020 Programme under the REBECA project - Red de excelencia en biotecnología azul (algas) de la región macaronesia (MAC1.1a/060). This work was also funded by Portuguese National Funds, through FCT − Fundação para a Ciência e a Tecnologia, the European Union, QREN, FEDER, COMPETE, by funding the CIBIO/InBIO (project UID/BIA/50027/2013 and POCI-01-0145-FEDER-006821). This manuscript is also a contribution to the updated checklist of Azorean cyanobacteria that is being prepared within the newly launched project AZORESBIOPORTAL – PORBIOTA (ACORES-01-0145-FEDER-000072), financed by FEDER in 85% and by Azorean Public funds by 15% through Operational Program Azores 2020.

- Description
- Cyanobacteria were identified according to Komárek and Anagnostidis (1998), Komárek and Anagnostidis (2008) and Komárek (2013).
Sampling
- Study Extent
-
Phytoplankton samples from 24 lakes in Corvo (1), Flores (6), Pico (5), and São Miguel (12) islands in the Azores archipelago were collected seasonally between 1996 and 2018.
- Sampling Description
- Phytoplankton samples were taken using Van Dorn bottle and a 10 µm mesh plankton net at lake maximum depth point. In deep lakes (maximum depth > 10 m), until 2010 discrete samples were collected at surface, mid-water column depth and 1 m above sediment. After 2010 a combined sample of the euphotic zone was obtained by mixing discrete 1 L samples collected at 1 m intervals from the surface to the bottom of the euphotic zone. In shallow lakes (maximum depth < 10 m) a surface sample (integrated sample of the first meter of the water column) was collected. Net samples were obtained by a trawl from 1 m above the sediment to the water column surface. All samples were preserved with 1% Lugol solution (v/v) and taxa were identified to the lower taxonomical level possible using light microscopy. Preserved samples after analysis were deposited in Faculdade de Ciências e Tecnologia, Universidade dos Açores.
