Description
The data presented in this paper derives from visual and destructive surveys done along the Portuguese rocky intertidal in the early 2000s. A total of 242 taxa were identified and their abundance quantified (101 Plantae, 37 Chromista, 101 Animalia, 2 Fungi, 1 Bacteria).
Data Records
The data in this sampling event 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 49 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
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.

| Funding | Fieldwork was financed by own resources. Laboratory work and initial data processing was mostly funded by Fundação Para a Ciência e a Tecnologia (FCT) though the grants SFRH/BD/8730/2002 (FPL) and SFRH/BD/8232/2002 (PAR). Final data curation and manuscript preparation was funded by the research project "ThermalBuffer" under the references POCI-01-0145-FEDER-031088 and PTDC/BIA-BMA/31088/2017. |
| Study Area Description | Data were collected during the autumns of 2001 and 2002. Sampling was carried out at 49 wave-exposed rocky shore locations along the Portuguese coast, covering the three major rocky stretches of shoreline in the Northern, Central and Southern regions. |
| Design Description | Specimens in this dataset were collected in field work carried out between autumns of 2001 and 2002. Observations derive from visual and destructive surveys done along the Portuguese coast. The occurrence and abundance of all easily-identified taxa (animals and algae, sensu latu) were recorded in situ. A semi-quantitative estimation of abundance was assigned to each taxa identified during the survey. We used a modified version of the scale established by Crisp and Southward 1958 — SACFOR, where abundances were encoded from 6 to 0 (where 6 means Superabundant; 5 - Abundant; 4 - Common; 3 - Frequent; 2 - Occasional ; 1 - Rare; and 0 - not found). |

Sampling Methods

| Quality Control | In addition to AlgaeBase (Guiry and Guiry 2021), authoritative identification guides and keys for the Eastern Atlantic and Mediterranean were used. Specifically, Dixon and Irvine (1977), Hiscock (1979), Irvine (1983), Bárbara and Cremades (1987), Christensen (1987), Fletcher (1987), Saldanha (1988), Burrows (1991), Cabioc'h et al. (1992), Maggs and Hommersand (1993), Hiscock (1986), Irvine and Chamberlain (1994), Brodie and Irvine (2003) were used for algae, and Naylor (1972), Lincoln (1979), Manuel (1981), Graham (1988), Hayward and Ryland (1991) were used for animals. All scientific names were standardized against the WoRMS - The World Register of Marine Species using the Taxon Match tool available at http://www.marinespecies.org/aphia.php?p=match (accessed on: 2021-07-07). |
Method step description:
- The steps that led to the final release of the dataset were as follows: (1) In-situ identification of species and attribution of a semi-quantitative abundance SACFOR score; (2) destructive sampling (substrate scraping) at three tidal levels and preservation of samples in formaldehyde; (3) cleaning of formaldehyde, sorting, and identification of specimens in the lab; (4) conversion of paper-based records from the field and from the lab into an electronic data format (spreadsheets); (5) integration of the field and laboratory datasets into a standardized format; (6) retrieval of missing geographical information, georeferencing of coordinates through Google Earth and general quality control; (7) standardization of taxonomy against the World Register of Marine Species.
